NAME

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

SYNOPSIS

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

will result the following PI in the DOM:

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

will have the same result as above.

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

setData

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.
