HTML::Selector::XPath.3pm

NAME

HTML::Selector::XPath - CSS Selector to XPath compiler

SYNOPSIS

   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');
 
 

DESCRIPTION

HTML::Selector::XPath is a utility function to compile CSS2 selector to the equivalent XPath expression.

CAVEATS

CSS SELECTOR VALIDATION

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.
