XML::LibXML::AttributeHash - phpMan

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.
