[RESOLVED] Regex, strip all content from within two html tags

Tak

I'm hoping someone out there can help me with my regular expressions. 🙂

What I'm trying to do is strip all "div" and "table" elements (along with their content) from a string.

What I have so far is this:

$string = preg_replace('/<div>.*<\/div>/', '', $string);
$string = preg_replace('/<table>.*<\/table>/', '', $string);

However, I'm not quite sure how to make it strip/match a few more HTML variables. For example, the following aren't getting stripped because they don't start with <table> or <div> exactly.

<table border="0" cellpadding="0" cellspacing="0">
<div style="font-size:12px;">

This is probably a really easy fix. Thanks for taking the time to read this. 🙂

Is this a full HTML document you're stripping?

No, it's not a full document. It's a small PHP include file that I'm looking to remove some of the HTML structure (just the tables, div tags & their content) from.

In that case, looks like regular expressions is the only way to go. Try something like this general pattern:

@<(tag1|tag2)[^>]*>.*?</\1>@is

The text "tag1"/"tag2" are placeholders for whichever HTML tag(s) you wish to match. Note that this pattern uses a backreference for the ending HTML tag, meaning you can use this one single pattern to match any number of HTML tags (instead of doing one preg_replace() per tag).

Regular expressions are so awesome. Thanks for helping me out. 🙂 This seems to be doing the trick, not to mention it's much better than what I was trying to do.
