This puts the HTML into a DOM object which can be parsed by individual tags, attributes, etc..  Here is an example of getting all the 'href' attributes and corresponding node values out of the 'a' tag. Very cool....
<?php
$myhtml = <<<EOF
<html>
<head>
<title>My Page</title>
</head>
<body>


<a href="/mypage1">Hello World!</a>


<a href="/mypage2">Another Hello World!</a>
</body>
</html>
EOF;
$doc = new DOMDocument();
$doc->loadHTML($myhtml);
$tags = $doc->getElementsByTagName('a');
foreach ($tags as $tag) {
      echo $tag->getAttribute('href').' | '.$tag->nodeValue."\n";
}
?>
This should output:
/mypage1 | Hello World!
/mypage2 | Another Hello World!

Note that this function doesn't parse the individual tags WITHIN the html file - it's all loaded as a "black box", and you end up with an XML widget that comprises nothing but the complete chunk of HTML.
I was hoping it would function as a sort of HTML-validator/parser, but that doesn't seem to be the case.

If you want to suppress output warnings from loadHTMLFile($url), put an @ sign in front. This even works in:
<?php
$load = @$dom->loadHTMLFile($url);
?>

Andy, the code you gave should not give that result.  In your code, $tag is an <a> element and the nodeValue of elements is null, according to the DOM2 spec.  You need to get at the text node first, before getting the node value.
<?
...
foreach ($tags as $tag) {
      echo $tag->getAttribute('href').' | '.$tag->childNodes->item(0)->nodeValue."\n";
}
?>
This should output:
/mypage1 | Hello World!
/mypage2 | Another Hello World!
