I want to take paragraph or div from html, but if it don't contain form. For example:

<p><form>I don't want this text</form>and not this text</p>
<p>I want to take this text</p>

I have working variant, without form filter.

/(?:<(?:p|div)[^>]*>)(.*)(?:<\/(?:p|div)>)/iu

And not working variant with filter

/(?:<(?:p|div)[^>]*>)((?:.(?!<form))*)(?:<\/(?:p|div)>)/iu

Can you help me?

  • What exactly is not working? In which cases does it give the wrong result (and what is the expected result in those cases)? –  Apr 15 '15 at 15:52

Warning: parse HTML with Regexp has always been, and will always be a bad idea.

Here is a slightly modified version of your regex:

/(?:<(?:p|div)[^>]*>)(?!.*\<form\>)(.*)(?:<\/(?:p|div)>)/iu

I improved it to allow you to catch any paragraph containing the word "form (and not the tag). Try it with this test:

<p><form>I don't want this text</form>and not this text</p>
<p>I want to take this text even if it contains the "form" word!</p>
<p>I want to take this text</p>
