How do you parse a file and pull a block of markup?

[quote author="nubianxp" date="1241481200"]@yorick: thanks for the code man, nice to have something to start with... one question, is it possible to maybe parse a remote file? e.g.

Code:

$remote = 'http://example.com/data.html';
$DOM = new DOMDocument();
$DOM->load($remote);
$content = $DOM->getElementById('somediv');

and do either

Code:

echo $content; OR
print_r($content);

i tested the above, but i get some parsing errors when using $dom->load():

Code:

Warning: DOMDocument::loadHTMLFile() [domdocument.loadhtmlfile]: error parsing attribute name in http://example.com/forecast.html, line: 19 in E:\localweb\projects\test\getfile.php on line 5

and a blank page if i use $dom->loadHTML()... anyway, appreciate the help. :lol:

I'm not really sure if you can parse a remote file using the DOM. However you could use file_get_contents() to fetch whatever is in that file and then parse it later on.

It would look like the following:

Code:

<?php
// Get the content from the remote file
$remote = file_get_contents('your_remote_file.html');

// Load the DOM
$DOM = new DOMDocument();

// Open the $remote variable using the DOM, not sure if it's possible
$DOM->load($remote);

// Parse it
