Constructor Detail

InscopeNamespaceResolver

public InscopeNamespaceResolver(NodeInfo node)

Create a NamespaceResolver that resolves according to the in-scope namespaces of a given node

Parameters:

node - the given node. Must not be null. If this is an element node, the resolver uses the in-scope namespaces of that element. If it is a document node, the only in-scope namespace is the XML namespace. If it is any other kind of node, then if the node has a parent element, the resolver uses the in-scope namespaces of the parent element, otherwise ithe only in-scope namespace is the XML namespace.

Method Detail

getURIForPrefix

public String getURIForPrefix(String prefix,
                     boolean useDefault)

Get the namespace URI corresponding to a given prefix. Return null if the prefix is not in scope.

Specified by:

getURIForPrefix in interface NamespaceResolver

Parameters:

prefix - the namespace prefix. May be the zero-length string, indicating that there is no prefix. This indicates either the default namespace or the null namespace, depending on the value of useDefault.

useDefault - true if the default namespace is to be used when the prefix is "". If false, the method returns "" when the prefix is "".

Returns:

the uri for the namespace, or null if the prefix is not in scope. The "null namespace" is represented by the pseudo-URI "".

iteratePrefixes

public Iterator<String> iteratePrefixes()

Get an iterator over all the prefixes declared in this namespace context. This will include the default namespace (prefix="") and the XML namespace where appropriate

Specified by:

iteratePrefixes in interface NamespaceResolver

Returns:

an iterator over all the prefixes for which a namespace binding exists, including the zero-length string to represent the null/absent prefix if it is bound

getNode

public NodeInfo getNode()

Get the node on which this namespace resolver is based

Returns:

the node on which this namespace resolver is based
