XML::LibXML::Attr(3)  User Contributed Perl Documentation XML::LibXML::Attr(3)

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

SYNOPSIS
         use XML::LibXML;
         # Only methods specific to Attribute nodes are listed here,
         # see 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/
       <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 "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
             $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.
