HTML::Selector::XPath - CSS Selector to XPath compiler
use HTML::Selector::XPath; my $selector = HTML::Selector::XPath->new("li#main"); $selector->to_xpath; # //li[@id='main'] # functional interface use HTML::Selector::XPath 'selector_to_xpath'; my $xpath = selector_to_xpath('div.foo');
HTML::Selector::XPath is a utility function to compile CSS2 selector to the equivalent XPath expression.
This module doesn't validate whether the original CSS Selector expression is valid. For example,
div.123foo
is an invalid CSS selector (class names should not begin with numbers), but this module ignores that and tries to generate an equivalent XPath expression anyway.

Most of the code is based on Joe Hewitt's getElementsBySelector.js on http://www.joehewitt.com/blog/2006-03-20.php and Andrew Dupont's patch to Prototype.js on http://dev.rubyonrails.org/ticket/5171, but slightly modified using Aristotle Pegaltzis' CSS to XPath translation table per http://plasmasturm.org/log/444/
