SYNOPSIS

 my $xml = $repository->xml;
 
 $doc = $xml->parse_string( $string );
 $doc = $xml->parse_file( $filename );
 $doc = $xml->parse_url( $url );
 
 $utf8_string = $xml->to_string( $dom_node, %opts );
 
 $dom_node = $xml->clone( $dom_node ); # deep
 $dom_node = $xml->clone_node( $dom_node ); # shallow
 
 # clone and return child nodes
 $dom_node = $xml->contents_of( $dom_node );
 # Return text child nodes as a string
 $utf8_string = $xml->text_contents_of( $dom_node );
 
 $dom_node = $xml->create_element( $name, %attr );
 $dom_node = $xml->create_text_node( $value );

DESCRIPTION

EPrints can use either XML::DOM, XML::LibXML or XML::GDOME modules to generate and process XML. Some of the functionality of these modules differs so this module abstracts such functionality so that all the module specific code is in one place.
