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

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 one 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. AUTHORS
