Package javax.xml.namespace

Examples of javax.xml.namespace.NamespaceContext

All get*(*) methods operate in the current scope for Namespace URI and prefix resolution.

Note that a Namespace URI can be bound to multiple prefixes in the current scope. This can occur when multiple XMLConstants.XMLNS_ATTRIBUTE ("xmlns") Namespace declarations occur in the same Start-Tag and refer to the same Namespace URI. e.g.

 <element xmlns:prefix1="http://Namespace-name-URI" xmlns:prefix2="http://Namespace-name-URI">

This can also occur when the same Namespace URI is used in multiple XMLConstants.XMLNS_ATTRIBUTE ("xmlns") Namespace declarations in the logical parent element hierarchy. e.g.
 <parent xmlns:prefix1="http://Namespace-name-URI"> <child xmlns:prefix2="http://Namespace-name-URI"> ... </child> </parent>

A prefix can only be bound to a single Namespace URI in the current scope.
