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') . "
";

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') . "
";

       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') . "
";

       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.
