const XercesWrapperNavigator &  theNavigator
) 
 

virtual XercesElementWrapper::~XercesElementWrapper (   )  [virtual]
 

Member Function Documentation

virtual XalanNode* XercesElementWrapper::appendChild (  XalanNode *  newChild  )  [virtual]
 

Adds the node newChild to the end of the list of children of this node.

If the newChild is already in the tree, it is first removed.

Parameters:
newChild The node to add.If it is a DocumentFragment object, the entire contents of the document fragment are moved into the child list of this node
Returns:
The node added.

Implements XalanElement.

virtual XercesElementWrapper* XercesElementWrapper::cloneNode (  bool  deep  )  const [virtual]
 

Returns a duplicate of this node.

This function serves as a generic copy constructor for nodes.

The duplicate node has no parent ( parentNode returns null.).
Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning any other type of node simply returns a copy of this node.

Parameters:
deep If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).
Returns:
The duplicate node.

Implements XalanElement.

virtual const XalanDOMString& XercesElementWrapper::getAttribute (  const XalanDOMString &  name  )  const [virtual]
 

Retrieves an attribute value by name.

Parameters:
name The name of the attribute to retrieve.
Returns:
The DOMAttr value as a string, or the empty string if that attribute does not have a specified or default value.

Implements XalanElement.

virtual XalanAttr* XercesElementWrapper::getAttributeNode (  const XalanDOMString &  name  )  const [virtual]
 

Retrieves an DOMAttr node by name.

Parameters:
name The name (nodeName) of the attribute to retrieve.
Returns:
The DOMAttr node with the specified name (nodeName) or null if there is no such attribute.

Implements XalanElement.

virtual XalanAttr* XercesElementWrapper::getAttributeNodeNS (  const XalanDOMString &  namespaceURI,
const XalanDOMString &  localName
)  const [virtual]
 

Retrieves an DOMAttr node by local name and namespace URI.

Parameters:
namespaceURI The namespace URI of the attribute to retrieve.
localName The local name of the attribute to retrieve.
Returns:
The DOMAttr node with the specified attribute local name and namespace URI or null if there is no such attribute.

Implements XalanElement.

virtual const XalanDOMString& XercesElementWrapper::getAttributeNS (  const XalanDOMString &  namespaceURI,
const XalanDOMString &  localName
)  const [virtual]
 

Retrieves an attribute value by local name and namespace URI.

Parameters:
namespaceURI The namespace URI of the attribute to retrieve.
localName The local name of the attribute to retrieve.
Returns:
The DOMAttr value as a string, or an empty string if that attribute does not have a specified or default value.

Implements XalanElement.

virtual const XalanNamedNodeMap* XercesElementWrapper::getAttributes (   )  const [virtual]
 

Gets a NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.

Implements XalanElement.

virtual const XalanNodeList* XercesElementWrapper::getChildNodes (   )  const [virtual]
 

Gets a NodeList that contains all children of this node.

If there are no children, this is a NodeList containing no nodes. The content of the returned NodeList is "live" in the sense that, for instance, changes to the children of the node object that it was created from are immediately reflected in the nodes returned by the NodeList accessors; it is not a static snapshot of the content of the node. This is true for every NodeList, including the ones returned by the getElementsByTagName method.

Implements XalanElement.

virtual XalanNodeList* XercesElementWrapper::getElementsByTagName (  const XalanDOMString &  name  )  const [virtual]
 

Returns a NodeList of all descendant elements with a given tag name, in the order in which they would be encountered in a preorder traversal of the DOMElement tree.

Caller is responsible for deleting the XalanNodeList instance.

Parameters:
name The name of the tag to match on. The special value "*" matches all tags.
Returns:
A list of matching DOMElement nodes.

Implements XalanElement.

virtual XalanNodeList* XercesElementWrapper::getElementsByTagNameNS (  const XalanDOMString &  namespaceURI,
const XalanDOMString &  localName
)  const [virtual]
 

Returns a DOMNodeList of all the DOMElements with a given local name and namespace URI in the order in which they would be encountered in a preorder traversal of the DOMDocument tree, starting from this node.

Caller is responsible for deleting the XalanNodeList instance.

Parameters:
namespaceURI The namespace URI of the elements to match on. The special value "*" matches all namespaces.
localName The local name of the elements to match on. The special value "*" matches all local names.
Returns:
A new DOMNodeList object containing all the matched Elements.

Implements XalanElement.

virtual XalanNode* XercesElementWrapper::getFirstChild (   )  const [virtual]
 

Gets the first child of this node.

If there is no such node, this returns null.

Implements XalanElement.

virtual IndexType XercesElementWrapper::getIndex (   )  const [virtual]
 

Get the node's index.

Valid only if the owner document reports that the document is node-order indexed.

Returns:
The index value, or 0 if the node is not indexed.

Implements XalanElement.

virtual XalanNode* XercesElementWrapper::getLastChild (   )  const [virtual]
 

Gets the last child of this node.

If there is no such node, this returns null.

Implements XalanElement.

virtual const XalanDOMString& XercesElementWrapper::getLocalName (   )  const [virtual]
 

Returns the local part of the qualified name of this node.

For nodes created with a DOM Level 1 method, such as createElement from the DOMDocument interface, it is null.

Implements XalanElement.

virtual const XalanDOMString& XercesElementWrapper::getNamespaceURI (   )  const [virtual]
 

Get the namespace URI of this node, or null if it is unspecified.

This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.

For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Implements XalanElement.

virtual XalanNode* XercesElementWrapper::getNextSibling (   )  const [virtual]
 

Gets the node immediately following this node.

If there is no such node, this returns null.

Implements XalanElement.

virtual const XalanDOMString& XercesElementWrapper::getNodeName (   )  const [virtual]
 

Gets the name of this node.

Implements XalanElement.

virtual NodeType XercesElementWrapper::getNodeType (   )  const [virtual]
 

An enum value representing the type of the underlying object.

Implements XalanElement.

virtual const XalanDOMString& XercesElementWrapper::getNodeValue (   )  const [virtual]
 

Gets the value of this node, depending on its type.

Implements XalanElement.

virtual XalanDocument* XercesElementWrapper::getOwnerDocument (   )  const [virtual]
 

Gets the DOMDocument object associated with this node.

This is also the DOMDocument object used to create new nodes. When this node is a DOMDocument or a DOMDocumentType which is not used with any DOMDocument yet, this is null.

Implements XalanElement.

virtual XalanNode* XercesElementWrapper::getParentNode (   )  const [virtual]
 

Gets the parent of this node.

All nodes, except Document, DocumentFragment, and Attr may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, a null DOMNode is returned.

Implements XalanElement.

virtual const XalanDOMString& XercesElementWrapper::getPrefix (   )  const [virtual]
 

Get the namespace prefix of this node, or null if it is unspecified.

Implements XalanElement.

virtual XalanNode* XercesElementWrapper::getPreviousSibling (   )  const [virtual]
 

Gets the node immediately preceding this node.

If there is no such node, this returns null.

Implements XalanElement.

virtual const XalanDOMString& XercesElementWrapper::getTagName (   )  const [virtual]
 

The name of the element.

For example, in: <elementExample id="demo"> ... </elementExample> , tagName has the value "elementExample". Note that this is case-preserving in XML, as are all of the operations of the DOM.

Implements XalanElement.

const DOMElementType* XercesElementWrapper::getXercesNode (   )  const
 

Get the Xerces node this instance represent.

Returns:
The Xerces node

virtual bool XercesElementWrapper::hasChildNodes (   )  const [virtual]
 

This is a convenience method to allow easy determination of whether a node has any children.

Returns:
true if the node has any children, false if the node has no children.

Implements XalanElement.

virtual XalanNode* XercesElementWrapper::insertBefore (  XalanNode *  newChild,
XalanNode *  refChild
)  [virtual]
 

Inserts the node newChild before the existing child node refChild.

If refChild is null, insert newChild at the end of the list of children.
If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before refChild. If the newChild is already in the tree, it is first removed. Note that a DOMNode that has never been assigned to refer to an actual node is == null.

Parameters:
newChild The node to insert.
refChild The reference node, i.e., the node before which the new node must be inserted.
Returns:
The node being inserted.

Implements XalanElement.

virtual bool XercesElementWrapper::isIndexed (   )  const [virtual]
 

Determine if the document is node-order indexed.

Returns:
true if the document is indexed, otherwise false.

Implements XalanElement.

virtual bool XercesElementWrapper::isSupported (  const XalanDOMString &  feature,
const XalanDOMString &  version
)  const [virtual]
 

Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

Parameters:
feature The string of the feature to test. This is the same name as what can be passed to the method hasFeature on DOMImplementation.
version This is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return true.
Returns:
Returns true if the specified feature is supported on this node, false otherwise.

Implements XalanElement.

virtual void XercesElementWrapper::normalize (   )  [virtual]
 

Puts all DOMText nodes in the full depth of the sub-tree underneath this DOMNode, including attribute nodes, into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates DOMText nodes, i.e., there are no adjacent DOMText nodes.

This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.

Note: In cases where the document contains DOMCDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between DOMText nodes and DOMCDATASection nodes.

Implements XalanElement.

virtual void XercesElementWrapper::removeAttribute (  const XalanDOMString &  name  )  [virtual]
 

Removes an attribute by name.

If the removed attribute is known to have a default value, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.
To remove an attribute by local name and namespace URI, use the removeAttributeNS method.

Parameters:
name The name of the attribute to remove.
Exceptions:
DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Implements XalanElement.

virtual XalanAttr* XercesElementWrapper::removeAttributeNode (  XalanAttr *  oldAttr  )  [virtual]
 

Removes the specified attribute node.

If the removed DOMAttr has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix, when applicable.

Parameters:
oldAttr The DOMAttr node to remove from the attribute list.
Returns:
The DOMAttr node that was removed.
Exceptions:
DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if oldAttr is not an attribute of the element.

Implements XalanElement.

virtual void XercesElementWrapper::removeAttributeNS (  const XalanDOMString &  namespaceURI,
const XalanDOMString &  localName
)  [virtual]
 

Removes an attribute by local name and namespace URI.

If the removed attribute has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix.
HTML-only DOM implementations do not need to implement this method.

Parameters:
namespaceURI The namespace URI of the attribute to remove.
localName The local name of the attribute to remove.
Exceptions:
DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Implements XalanElement.

virtual XalanNode* XercesElementWrapper::removeChild (  XalanNode *  oldChild  )  [virtual]
 

Removes the child node indicated by oldChild from the list of children, and returns it.

Parameters:
oldChild The node being removed.
Returns:
The node removed.

Implements XalanElement.

virtual XalanNode* XercesElementWrapper::replaceChild (  XalanNode *  newChild,
XalanNode *  oldChild
)  [virtual]
 

Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node.

If newChild is a DOMDocumentFragment object, oldChild is replaced by all of the DOMDocumentFragment children, which are inserted in the same order.

If the newChild is already in the tree, it is first removed.

Parameters:
newChild The new node to put in the child list.
oldChild The node being replaced in the list.
Returns:
The node replaced.

Implements XalanElement.

virtual void XercesElementWrapper::setAttribute (  const XalanDOMString &  name,
const XalanDOMString &  value
)  [virtual]
 

Adds a new attribute.

If an attribute with that name is already present in the element, its value is changed to be that of the value parameter. This value is a simple string, it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an DOMAttr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNode to assign it as the value of an attribute.

Parameters:
name The name of the attribute to create or alter.
value Value to set in string form.
Exceptions:
DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Implements XalanElement.

virtual XalanAttr* XercesElementWrapper::setAttributeNode (  XalanAttr *  newAttr  )  [virtual]
 

Adds a new attribute.

If an attribute with that name (nodeName) is already present in the element, it is replaced by the new one.

Parameters:
newAttr The DOMAttr node to add to the attribute list.
Returns:
If the newAttr attribute replaces an existing attribute, the replaced DOMAttr node is returned, otherwise null is returned.
Exceptions:
DOMException WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another DOMElement object. The DOM user must explicitly clone DOMAttr nodes to re-use them in other elements.

Implements XalanElement.

virtual XalanAttr* XercesElementWrapper::setAttributeNodeNS (  XalanAttr *  newAttr  )  [virtual]
 

Adds a new attribute.

If an attribute with that local name and namespace URI is already present in the element, it is replaced by the new one.

Parameters:
newAttr The DOMAttr node to add to the attribute list.
Returns:
If the newAttr attribute replaces an existing attribute with the same local name and namespace URI, the replaced DOMAttr node is returned, otherwise null is returned.
Exceptions:
DOMException WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another DOMElement object. The DOM user must explicitly clone DOMAttr nodes to re-use them in other elements.

Implements XalanElement.

virtual void XercesElementWrapper::setAttributeNS (  const XalanDOMString &  namespaceURI,
const XalanDOMString &  qualifiedName,
const XalanDOMString &  value
)  [virtual]
 

Adds a new attribute.

If the given namespaceURI is null or an empty string and the qualifiedName has a prefix that is "xml", the new attribute is bound to the predefined namespace "http://www.w3.org/XML/1998/namespace". If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the qualifiedName, and its value is changed to be the value parameter. This value is a simple string, it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create a DOMAttr node plus any DOMText and DOMEntityReference nodes, build the appropriate subtree, and use setAttributeNodeNS or setAttributeNode to assign it as the value of an attribute.

Parameters:
namespaceURI The namespace URI of the attribute to create or alter.
localName The local name of the attribute to create or alter.
value The value to set in string form.
Exceptions:
DOMException INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the qualifiedName is malformed, if the qualifiedName has a prefix that is "xml" and the namespaceURI is neither null nor an empty string nor "http://www.w3.org/XML/1998/namespace", or if the qualifiedName has a prefix that is "xmlns" but the namespaceURI is neither null nor an empty string, or if if the qualifiedName has a prefix different from "xml" and "xmlns" and the namespaceURI is null or an empty string.

Implements XalanElement.

virtual void XercesElementWrapper::setNodeValue (  const XalanDOMString &  nodeValue  )  [virtual]
 

Sets the value of the node.

Any node which can have a nodeValue (

See also:
getNodeValue) will also accept requests to set it to a string. The exact response to this varies from node to node -- Attribute, for example, stores its values in its children and has to replace them with a new Text holding the replacement value.
For most types of Node, value is null and attempting to set it will throw DOMException(NO_MODIFICATION_ALLOWED_ERR). This will also be thrown if the node is read-only.

Implements XalanElement.

virtual void XercesElementWrapper::setPrefix (  const XalanDOMString &  prefix  )  [virtual]
 

Set the namespace prefix of this node.

Note that setting this attribute, when permitted, changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the DOMElement and DOMAttr interfaces, when applicable.

Note also that changing the prefix of an attribute, that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespaceURI and localName do not change.

Parameters:
prefix The prefix of this node.
Exceptions:
DOMException INVALID_CHARACTER_ERR: Raised if the specified prefix contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the specified prefix is malformed, if the specified prefix is "xml" and the namespaceURI of this node is different from "http://www.w3.org/XML/1998/namespace", if specified prefix is "xmlns" and the namespaceURI is neither null nor an empty string, or if the localName is null.
