DOMDocument::loadHTMLFile

(PHP 5)

DOMDocument::loadHTMLFile Load HTML from a file

Description

public bool DOMDocument::loadHTMLFile ( string $filename [, int $options = 0 ] )

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

Parameters

filename

The path to the HTML file.

options

Since PHP 5.4.0 and Libxml 2.6.0, you may also use the options parameter to specify additional Libxml parameters.

Return Values

Returns TRUE on success or FALSE on failure. If called statically, returns a DOMDocument 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.

This method may be called statically, but will issue an E_STRICT error.

While malformed HTML should load successfully, this function may generate E_WARNING errors when it encounters bad markup. libxml's error handling functions may be used to handle these errors.

Examples

Example #1 Creating a Document

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

Changelog

Version Description
5.4.0 Added options parameter.

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>
<p><a href="/mypage1">Hello World!</a></p>
<p><a href="/mypage2">Another Hello World!</a></p>
</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!

<?php
// try this html listing example for all nodes / includes a few getElementsByTagName options:

$file $DOCUMENT_ROOT"test.html";
$doc = new DOMDocument();
$doc->loadHTMLFile($file);

// example 1:
$elements $doc->getElementsByTagName('*');
// example 2:
$elements $doc->getElementsByTagName('html');
// example 3:
//$elements = $doc->getElementsByTagName('body');
// example 4:
//$elements = $doc->getElementsByTagName('table');
// example 5:
//$elements = $doc->getElementsByTagName('div');

if (!is_null($elements)) {
  foreach (
$elements as $element) {
    echo 
"<br/>"$element->nodeName": ";

   
$nodes $element->childNodes;
    foreach (
$nodes as $node) {
      echo 
$node->nodeValue"\n";
    }
  }
}

The options for surpressing errors and warnings will not work with this as they do for loadXML()
e.g.
<?php
$doc
->loadHTMLFile($fileLIBXML_NOWARNING LIBXML_NOERROR);
?>
will not work.
you must use:
<?php
libxml_use_internal_errors
(true);
$doc->loadHTMLFile($file);
?>
and handle the exceptions as neccesarry.

In this post http://softontherocks.blogspot.com/2014/11/descargar-el-contenido-de-una-url_11.html I found a simple way to get the content of a URL with DOMDocument, loadHTMLFile and saveHTML().

function getURLContent($url){
    $doc = new DOMDocument;
    $doc->preserveWhiteSpace = FALSE;
    @$doc->loadHTMLFile($url);
    return $doc->saveHTML();
}
