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

SYNOPSIS
      use XML::LibXML;
      # Only methods specific to Attribute nodes are listed here,
      # see the XML::LibXML::Node manpage for other methods

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

DESCRIPTION
    This is the interface to handle Attributes like ordinary nodes. The
    naming of the class relies on the W3C DOM documentation.

METHODS
    The class inherits from XML::LibXML::Node. The documentation for
    Inherited methods is not listed here.

    Many functions listed here are extensively documented in the DOM Level 3
    specification (<http://www.w3.org/TR/DOM-Level-3-Core/>). Please refer
    to the specification for extensive 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 "createAttribute" 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
          $string = $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 tries to bound the attribute to a given namespace. If
        $nsURI is undefined or empty, the function discards any previous
        association of the attribute with a namespace. If the namespace was
        not previously declared in the context of the attribute, this
        function will fail. In this case you may wish to call setNamespace()
        on the ownerElement. If the namespace URI is non-empty and declared
        in the context of the attribute, but only with a different
        (non-empty) prefix, then the attribute is still bound to the
        namespace but gets a different prefix than $prefix. The function
        also fails if the prefix is empty but the namespace URI is not
        (because unprefixed attributes should by definition belong to no
        namespace). This function returns 1 on success, 0 otherwise.

    isId
          $bool = $attr->isId;

        Determine whether an attribute is of type ID. For documents with a
        DTD, this information is only available if DTD loading/validation
        has been requested. For HTML documents parsed with the HTML parser
        ID detection is done automatically. In XML documents, all "xml:id"
        attributes are considered to be of type ID.

    serializeContent($docencoding)
          $string = $attr->serializeContent;

        This function is not part of DOM API. It returns attribute content
        in the form in which it serializes into XML, that is with all
        meta-characters properly quoted and with raw entity references
        (except for entities expanded during parse time). Setting the
        optional $docencoding flag to 1 enforces document encoding for the
        output string (which is then passed to Perl as a byte string).
        Otherwise the string is passed to Perl as (UTF-8 encoded)
        characters.
