Method Detail

getBaseIdentifier

public java.lang.String getBaseIdentifier()

Return the base identifier.

Specified by:

getBaseIdentifier in interface org.apache.xml.utils.PrefixResolver

Returns:

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.

getNamespaceForPrefix

public java.lang.String getNamespaceForPrefix(java.lang.String aPrefix)

Given a namespace, get the corrisponding prefix. This assumes that the PrefixResolver holds its own namespace context, or is a namespace context itself.

Specified by:

getNamespaceForPrefix in interface org.apache.xml.utils.PrefixResolver

Parameters:

prefix - The prefix to look up, which may be an empty string ("") for the default Namespace.

Returns:

The associated Namespace URI, or null if the prefix is undeclared in this context.

getNamespaceForPrefix

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.

Specified by:

getNamespaceForPrefix in interface org.apache.xml.utils.PrefixResolver

Parameters:

prefix - The prefix to look up, which may be an empty string ("") for the default Namespace.

context - The node context from which to look up the URI.

Returns:

The associated Namespace URI as a string, or null if the prefix is undeclared in this context.

handlesNullPrefixes

public boolean handlesNullPrefixes()

Specified by:

handlesNullPrefixes in interface org.apache.xml.utils.PrefixResolver

setNamespaceforPrefix

public void setNamespaceforPrefix(java.lang.String aPrefix,
                                  java.lang.String aUri,
                                  org.w3c.dom.Node aContext)
