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.
