Basic xPath getting lots of warnings

Question

I am trying to learn how to work with xPath and PHP by loading a simple URL as a DOM object and querying the DOM using xPath. I have been running in to a lot of trouble and have been trying to troubleshoot these warnings messages for quite a while now with no success.

I appreciate any suggestions as to why this happening.

Many thanks in advance!

PHP

<?php
$doc = new DOMDocument();
$doc->loadHTMLFile("http://n5a.software.com/calendar/da2013/profile.php?__id=691");

$xpath = new DOMXpath($doc);

$elements = $xpath->query("//ul[@class='flper']/li[2]");

if (!is_null($elements)) {
    foreach ($elements as $element) {
        $nodes = $element->childNodes;
        foreach ($nodes as $node) {
            echo $node->nodeValue. "\n";
        }
    }
}

?>

Output

Disable warnings with libxml_use_internal_errors(true) http://www.php.net/manual/en/function.libxml-use-internal-errors.php

It is malformed HTML, nothing you can really do about it if you do not control the HTML.

Thanks for the reply. That got rid of most of the warnings, however, I am still getting this one: `Warning: DOMDocument::loadHTMLFile(): Empty string supplied as input in C:\xampp\htdocs\www\test\xpathgenius.php on line 15` Any ideas why this is? – AnchovyLegend Jun 29 '13 at 03:09
loadHTMLFile() takes in URL stings from an input file and I double checked that there arent any excessive new lines that might be mistaken for a URL... – AnchovyLegend Jun 29 '13 at 03:13
Which line is line 15? probably not the closing curly bracket. – Jens Erat Jun 29 '13 at 08:40
