Fields Summary
Constructors Summary
Methods Summary
public java.lang.String getBaseIdentifier()
Return the base identifier.
return
The base identifier from where relative URIs should be absolutized, or null if the base ID is unknown.
CAVEAT: Note that the base URI in an XML document may vary with where you are in the document, if part of the doc's contents were brought in via an external entity reference or if mechanisms such as xml:base have been used. Unless this PrefixResolver is bound to a specific portion of the document, or has been kept up to date via some other mechanism, it may not accurately reflect that context information.
public java.lang.String getNamespaceForPrefix(java.lang.String prefix)
Given a namespace, get the corrisponding prefix. This assumes that the PrefixResolver holds its own namespace context, or is a namespace context itself.
param
prefix The prefix to look up, which may be an empty string ("") for the default Namespace.
return
The associated Namespace URI, or null if the prefix is undeclared in this context.
public java.lang.String getNamespaceForPrefix(java.lang.String prefix, org.w3c.dom.Node context)
Given a namespace, get the corresponding prefix, based on the context node.
param
prefix The prefix to look up, which may be an empty string ("") for the default Namespace.
param
context The node context from which to look up the URI.
return
The associated Namespace URI as a string, or null if the prefix is undeclared in this context.
