xml::libxml::pi

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

NAME

       XML::LibXML::PI - XML::LibXML Processing Instructions

SYNOPSIS

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

	 $pinode->setData( $data_string );
	 $pinode->setData( name=>string_value [...] );

DESCRIPTION

       Processing instructions are implemented with XML::LibXML with read and write access. The PI data is the PI without the PI target (as
       specified in XML 1.0 [17]) as a string. This string can be accessed with getData as implemented in XML::LibXML::Node.

       The write access is aware about the fact, that many processing instructions have attribute like data. Therefore setData() provides besides
       the DOM spec conform Interface to pass a set of named parameter. So the code segment

	 my $pi = $dom->createProcessingInstruction("abc");
	 $pi->setData(foo=>'bar', foobar=>'foobar');
	 $dom->appendChild( $pi );

       will result the following PI in the DOM:

	 <?abc foo="bar" foobar="foobar"?>

       Which is how it is specified in the DOM specification. This three step interface creates temporary a node in perl space. This can be
       avoided while using the insertProcessingInstruction() method. Instead of the three calls described above, the call

	 $dom->insertProcessingInstruction("abc",'foo="bar" foobar="foobar"');

       will have the same result as above.

       XML::LibXML::PI's implementation of setData() documented below differs a bit from the the standard version as available in
       XML::LibXML::Node:

       setData
	     $pinode->setData( $data_string );
	     $pinode->setData( name=>string_value [...] );

	   This method allows to change the content data of a PI. Additionally to the interface specified for DOM Level2, the method provides a
	   named parameter interface to set the data. This parameter list is converted into a string before it is appended to the PI.
