=head1 NAME

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

=head1 SYNOPSIS

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

=head1 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.
