I'm using the following regex to capture the entire src attribute using preg_match_all:

<iframe.*src=\"(.*)\".*><\/iframe>

I'm now looking for a way to capture the src attribute (including parameters) only if the url contains either youtube or vimeo. My attempt failed miserably:

<iframe.*src=.*(?:youtube|vimeo).*>\/iframe>

Any suggestions would be greatly appreciated.

many thanks,

devin

You are missing a left angle – Andy G Feb 05 '18 at 16:29

Split the two tasks: 1) retrieve the src content, 2) analyze that string (with another regex or other parser tecniques) – Oneiros Feb 05 '18 at 16:31

Use an XPath query: `//iframe/@src[contains(.,"youtube") or contains(.,"vimeo")]`. Don't use regex to parse html. – Casimir et Hippolyte Feb 05 '18 at 16:34

With regex you can do something [like this](https://regex101.com/r/wdRJB0/1). – bobble bubble Feb 05 '18 at 16:36
