NAME

XML::LibXML::Devel::SetLineNumber - set the line number for an XML::LibXML::Node

SYNOPSIS

  use XML::LibXML::Devel::SetLineNumber;
  
  my $node = $document->getElementsByTagName('foo')->get_node(1);
  set_line_number($node, 8);
  say $node->line_number;  # says "8"

DESCRIPTION

This module exports one function:

set_line_number($node, $number)

Sets a node's line number.

Why in name of all that is good and holy would you want to do that? Frankly, you probably don't. And you probably shouldn't.

There's just about one sitution where it makes sense. If you are, say, writing a parser for a non-XML format that happens to have an XML-like data model, then you might wish to parse your format into an XML::LibXML document with elements, attributes and so on. And you might want all those nodes to return the correct line numbers when the line_number method is called on them. Say, for instance that you're working on HTML::HTML5::Parser.

THIS MODULE IS WELL DODGY

And you're a fool if you use it.

If you do feel you really must use this module, it's probably best to load it like this:

 eval {
   require XML::LibXML::Devel::SetLineNumber;
   import XML::LibXML::Devel::SetLineNumber;
   1;
 } or *set_line_number = sub { 1 };

Instead of the normal use XML::LibXML::Devel::SetLineNumber.
