Use PHP to delete section of .html file

Question

I have an HTML page I'd like to edit. I want to remove a certain section of the .html file such as.

<div id="gg">
......
......
</div>

How can I do this?

You mean once, or serially on request (and/or some condition)? — Jared Farrish, Oct 10 '11 at 00:58

I would recommend using PHP's DOM library:

$dom = new DOMDocument;
$dom->loadHTML('<html string />'); // Or $dom->loadHTMLFile('file_name.html');

$xpath = new DOMXPath($dom);
$nodes = $xpath->query('//div[id="gg"]');
if($nodes->length)
  $nodes[0]->parentNode->removeChild($nodes[0]);

$dom->saveHTML(); // Or $dom->saveHTMLFile('file_name.html');

$file = file_get_contents("index.html");
$file = preg_replace('/<div id="gg">.*?<\/div>/im', '' $file);
file_put_contents($file);

I not tested this code.

Attention: nested divs break html structure.

What happens if there's a nested `div` in there? – imm Oct 10 '11 at 01:00

You might have some luck using an XML (or HTML) parser. This one for PHP 5 looks really easy to use, and provides a mechanism for finding a particular element by ID and then setting its contents to an empty string.
