Apache XML Commons Resolver Tools package
This package implements several tool classes for catalog-based entity resolution:
org.apache.xml.resolver.tools.CatalogResolver
org.apache.xml.resolver.tools.ResolvingXMLReader
org.apache.xml.resolver.tools.ResolvingParser
Typically, these classes can be used in other applications. For example, running the Saxon XSLT processor with the arguments:
-x org.apache.xml.resolver.tools.ResolvingXMLReader -y org.apache.xml.resolver.tools.ResolvingXMLReader -r org.apache.xml.resolver.tools.CatalogResolver
will provide catalog-based entity resolution for all of the entities and stylesheets that you use. (The CatalogResolver can only be used with Saxon 6.1 or later.)
In order to use these classes, you must have the JAXP 1.1 jar files in your CLASSPATH.
