PHP : Function Reference : DOM Functions : DOMDocument->loadHTMLFile()

DOMDocument->loadHTMLFile()

Load HTML from a file ()

DOMDocument{
boolloadHTMLFile(stringfilename);
}

The function parses the HTML document in the file named filename. Unlike loading XML, HTML does not have to be well-formed to load.

This function may also be called statically to load and create a DOMDocument object. The static invocation may be used when no DOMDocument properties need to be set prior to loading.

Parameters

filename

The path to the HTML file.

Return Values

Returns TRUE on success or FALSE on failure.

Errors/Exceptions

If an empty string is passed as the filename or an empty file is named, a warning will be generated. This warning is not generated by libxml and cannot be handled using libxml's error handling functions.

Examples

Example523.Creating a Document

<?php
$doc
= new DOMDocument();
$doc->loadHTMLFile("filename.php");
echo
$doc->saveHTML();
?>

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!
