NAME

XML::LibXML::Attr - XML::LibXML Attribute Class  

SYNOPSIS

  $attr = XML::LibXML::Attr->new($name [,$value]);
  $string = $attr->getValue();
  $value = $attr->value;
  $attr->setValue( $string );
  $node = $attr->getOwnerElement();
  $attr->setNamespace($nsURI, $prefix);

 

DESCRIPTION

This is the interface to handle Attributes like ordinary nodes. The naming of the class relies on the W3C DOM documentation.
new
  $attr = XML::LibXML::Attr->new($name [,$value]);

Class constructor. If you need to work with iso encoded strings, you should always use the createAttrbute of XML::LibXML::Document.

getValue
  $string = $attr->getValue();

Returns the value stored for the attribute. If undef is returned, the attribute has no value, which is different of being not specified.

value
  $value = $attr->value;

Alias for getValue()

setValue
  $attr->setValue( $string );

This is needed to set a new attribute value. If iso encoded strings are passed as parameter, the node has to be bound to a document, otherwise the encoding might be done incorrectly.

getOwnerElement
  $node = $attr->getOwnerElement();

returns the node the attribute belongs to. If the attribute is not bound to a node, undef will be returned. Overwriting the underlying implementation, the parentNode function will return undef, instead of the owner element.

setNamespace
  $attr->setNamespace($nsURI, $prefix);

This function activates a namespace for the given attribute. If the attribute was not previously declared in the context of the attribute this function will be silently ignored. In this case you may wish to call setNamespace() on the ownerElement.
