I'm confused because the thread you linked to is already very good.
You mostly use
in live inspections (ie when you need browser for JS) and as far as I remember did WWW::Mechanize::Firefox and its various siblings support both.
The alternative is mirroring the DOM into a Perl/XML data structure and using the query API. (Mostly like xpath)
Maybe you should ask more precisely and show what you tried?
update
> 1) Find the 6th and 9th rows in a named table (given an id) and pull out the name and value pairs.
> 2) Slurp in every row in a named table and parse out the name value pairs.
See
- $mech->xpath( $query, %options)
and alternatively
- $mech->select( $name, $value )
Both methods support querying children elements of a given ID.
Query syntax is not a Perl question, but there are plenty of good tutorials online.
Look out for browser features/addons allowing to play around with queries.
