Hi Monks,
I am trying to parse some URL with HTML TreeBuilder XPATH.
I retrieve an URL using LWP UserAgent which is loaded to $response->content.
Here's the code that loads that variable to a $tree instance:
my $tree = HTML::TreeBuilder::XPath->new;
$tree->parse($response->content);
my $t = $tree->findnodes(qq{/html/body/form/div});
print $t->size;
If I print the content of $response->content to a plain html file and open it using Firefox, the total amount of /html/body/form/div's is 19.
However, printing $t->size results in only 12..
Why is this happening??
$tree is ignoring most of my divs and so I can't retrieve data from them....
Thanks!

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
