Grep help - removing text within a tag

[a k]

Hey all, 

I'm looking to use grep to remove text contained within a tag (including the tag itself). More specifically - I need to find and remove a bunch of iframe tags from multiple .txt files.

Here's an example tag:

<iframe src="https://website.com/1.0/ifr?zid=123456&cb=${CACHEBUSTER}&abc_imp=${AUC_ID}&c=${CLICK_URL_ENC}&" frameborder="0" scrolling="no" width="123" height="456"></iframe>

because the zid, width and height always differ and appear in other places in the document (that need to be preserved) I cant do a regular find and replace.

 a complete beginner to BBEDIT and grep so apologies if this question is a bit remedial. I have bunch of code cleanup tasks that are very repetitive and I'm confident could be solved with grep, just not 100% sure how to go about it.

Can you put the output you expect for this string?

The find pattern would be "<iframe.*?</iframe>" with "Grep" checked. You can use the Multi-File Search... dialog to run this against a folder containing your .txt files to see how many matches there are.

When I'm doing multi-file work like this I'll usually start out doing a Find All in the multi-file dialog and looking at all the results. If it looks like I want to do a replace all then I can go back into the dialog and do that. The replace pattern would be blank if you want to remove the iframe tags.

If I need to be more discerning I'll work through each file by file in the results using Find Next to make sure that I want to replace all the iframes. Or refine the find pattern to be more specific.

Sorry for being unclear - I want to remove the text so output would be blank

Thanks so much! This did the trick. I've been familiarizing myself with multi-file search and am very excited to now have such a powerful tool to use for these repetitive tasks. Hoping to learn more about grep as well as Text Factory
