Hi All,
I was trying to parse Item tag with regEx but I am having problems because $capture->{_content} as a string is being translated to some other characterset. So, I am trying to pull out <item> tag using below method and I keep getting this error. Can someone please let me know why?
Error: XPathContext: lost current node at link_ext2.pl line 30
#!/usr/bin/perl -w
#use strict;
use warnings;
use XML::RSS::LibXML;
use XML::LibXML;
use LWP::UserAgent;
use Data::Dumper;
#my ( $htmlInfile, $htmlOutfile, $cssOutfile ) = @ARGV;
my $html_link = "http://rss.news.yahoo.com/rss/topstories";
my $parser = XML::LibXML->new;
my $client = LWP::UserAgent->new();
my $capture = $client->get("$html_link") || die"$!\n";
useLibXmlParseXmlItems($capture->{_content});
sub useLibXmlParseXmlItems
{
my $rss = XML::RSS::LibXML->new;
$rss->parse($_[0]) || die "Could not parse. <$!>";
my $xp = XML::LibXML::XPathContext->new($rss);
my @nodes = $xp->findnodes("/rss/channel/item");
#print @nodes;
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
