XML::LibXML::AttributeUser(Contributed Perl DocXML::LibXML::AttributeHash(3pm)NAMEXML::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.
