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
           "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.
