Hello dear anonymous_monk! I am triying to understand your posting!


you refer to the page that explains and hepls finding xpaths. That is very very interesting! I am trying to learn something here.

you use this link: http://www.perlmonks.org/?node_id=865792

It leads to this code!

this is a  great  great  totuorial and a supergreat tool: Lemme ask yo
+u if i got this right!? With that   i can determine the paths - in ot
+her words 
i can find out all the paths in a HTML-file!? 
$ perl htmltreexpather.pl select.html _tag  option
HTML::Element=HASH(0xb139ec)    0.1.1.0.0
Chose Some aaa
/html/body/form/select/option
/html/body/form/select/option
/html/body[@bgcolor='red']/form[@action='/foo.cgi' and @name='queryfoo
+']/select[@name='singlelist']/option[@value='aaa']

Question: this above mentioned code helps to throw out the Paths of a (general) HTML-document!?!?

At least you make usage here: 


#!/usr/bin/perl --

use strict;
use warnings;

use HTML::TreeBuilder::XPath;
#~ $XML::XPathEngine::DEBUG = 1;
my $tree = HTML::TreeBuilder::XPath->new;
$tree->parse_content(<<'__HTML__');

That is very very impressive. I try to understand this code - and your usage of your example -that you were refering to! 


$ perl htmltreexpather.pl select.html _tag  option
HTML::Element=HASH(0xb139ec)    0.1.1.0.0
Chose Some aaa
/html/body/form/select/option
/html/body/form/select/option
/html/body[@bgcolor='red']/form[@action='/foo.cgi' and @name='queryfoo
+']/select[@name='singlelist']/option[@value='aaa']
