Re: HTML and Xpath

Maybe an oversight, maybe a concious decision, but since each $result is a HTML::Element, you may need to detach it from the tree, seems to work

#!/usr/bin/perl --

use strict;
use warnings;

use HTML::TreeBuilder::XPath;

my $tree = HTML::TreeBuilder::XPath->new;
$tree->parse_content(<<'__HTML__');
<html>
    <body>
        <div>
            <div class="here">this's the value</div>
        </div>
        <div>
            <div class="here">this's the value</div>
        </div>
        <div>
            <div class="here">this's the value</div>
        </div>
        <div>
            <div class="here">this's the value</div>
        </div>
        <div>
            <div class="here">this's the value</div>
        </div>
        <div>
            <div class="here">this's the value</div>
        </div>
    </body>
</html>
__HTML__


for my $result ($tree->findnodes(q{/html/body/div})) {
    print "$result ", $result->detach(),"\n<br>\n";
    print $result->findvalue(q{//div[@class="here"]});
    print "\n<br>\n\n";

}

Instead of detaching (which modifies tree), you could clone `print $result->clone->findvalue(q{//div[@class="here"]});` [download]	[reply] [d/l]

Yes, i test and both method works, "clone" is really a good option too, thank you	[reply]

Instead of detaching, you could also `print $result->findvalue(q{./div[@class="here"]});` [download] or `print $result->findvalue(q{div[@class="here"]});` [download]	[reply] [d/l] [select]

Thank you very much, as you told, detaching it from the tree works perfectly. Thk U again	[reply]
