Re: get data from xpath

[tobyink]

A few problems:

• You mention a URL, and you create a UA object, but you never actually use the UA to retrieve any HTML from the URL.

  Anyway, you don't need to use LWP::UserAgent directly because HTML::TreeBuilder::XPath supplies a new_from_url method.

• You use HTML::Selector::XPath - this module is aimed at turning CSS-style selectors into XPath expressions, but you already have an XPath, so you don't need this module!

• You're using @id and @href within double quotes - this will be interpreted as two Perl arrays! You want to single quote the XPath.

• There shouldn't be a slash at the end of the XPath.

The following works:

use 5.010;
use strict;
use warnings;

use HTML::TreeBuilder::XPath;

my $url  = "http://www.youtube.com/results?search_query=run+flo+rida";
my $tree = HTML::TreeBuilder::XPath->new_from_url($url);

my $xpath = '(//*[@id="search-results"]/li)[1]/div[2]/h3/a/@href';
my @nodes = $tree->findnodes($xpath);

say $_->getValue for @nodes;
