Constructor Detail

PrefixResolverDefault

public PrefixResolverDefault(Node xpathExpressionContext)
Construct a PrefixResolverDefault object.

Method Detail

getNamespaceForPrefix

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

Specified by:
getNamespaceForPrefix in interface PrefixResolver
Parameters:
prefix - Prefix to resolve.
Returns:
Namespace that prefix resolves to, or null if prefix is not bound.

getNamespaceForPrefix

public java.lang.String getNamespaceForPrefix(java.lang.String prefix,
                                              Node namespaceContext)
Given a namespace, get the corrisponding prefix. Warning: This will not work correctly if namespaceContext is an attribute node.
Specified by:
getNamespaceForPrefix in interface PrefixResolver
Parameters:
prefix - Prefix to resolve.
namespaceContext - Node from which to start searching for a xmlns attribute that binds a prefix to a namespace.
Returns:
Namespace that prefix resolves to, or null if prefix is not bound.

getBaseIdentifier

public java.lang.String getBaseIdentifier()
Return the base identifier.
Specified by:
getBaseIdentifier in interface PrefixResolver
Returns:
null

handlesNullPrefixes
