DESCRIPTION

The Web::DOM::XPathNSResolver class implements the DOM XPathNSResolver interface.

In the DOM Perl Binding, an XPathNSResolver object can be represented as either a Perl subroutine (code) reference or an object returned by the create_ns_resolver method of the Document object. The Web::DOM::XPathNSResolver class is used for the latter. In other word, the class is used to wrap an Web::DOM::Node object by the XPathNSResolver interface.

If you'd like to define a custom namespace prefix resolver, you should use a simple subroutine as an XPathNSResolver. The subroutine will be invoked by the XPath parser when a namespace resolution is performed, with two arguments: $self (the code reference itself) and $prefix (the namespace prefix to resolve). The subroutine is expected to return the corresponding namespace URL, as a character string, or undef if the prefix is not has corresponding namespace URL.

METHOD

The following method is available:

$url = $resolver->lookup_namespace_uri ($prefix)

Return the namespace URL associated with the specified namespace prefix. [NSRESOLVER]
