XML::LibXML::AttributeHash(3)  User Contributed Perl Documentation  XML::LibXML::AttributeHash(3)

NAME
       XML::LibXML::AttributeHash - tie an XML::LibXML::Element to a hash to access its
       attributes

SYNOPSIS
	tie my %hash, 'XML::LibXML::AttributeHash', $element;
	$hash{'href'} = 'http://example.com/';
	print $element->getAttribute('href') . "\n";

DESCRIPTION
       This class allows an element's attributes to be accessed as if they were a plain old Perl
       hash. Attribute names become hash keys. Namespaced attributes are keyed using Clark
       notation.

	my $XLINK = 'http://www.w3.org/1999/xlink';
	tie my %hash, 'XML::LibXML::AttributeHash', $element;
	$hash{"{$XLINK}href"} = 'http://localhost/';
	print $element->getAttributeNS($XLINK, 'href') . "\n";

       There is rarely any need to use XML::LibXML::AttributeHash directly. In general, it is
       possible to take advantage of XML::LibXML::Element's overloading. The example in the
       SYNOPSIS could have been written:

	$element->{'href'} = 'http://example.com/';
	print $element->getAttribute('href') . "\n";

       The tie interface allows the passing of additional arguments to
       XML::LibXML::AttributeHash:

	tie my %hash, 'XML::LibXML::AttributeHash', $element, %args;

       Currently only one argument is supported, the boolean "weaken" which (if true) indicates
       that the tied object's reference to the element should be a weak reference. This is used
       by XML::LibXML::Element's overloading. The "weaken" argument is ignored if you don't have
       a working Scalar::Util::weaken.
