in reply to RegEx - Positive Look-ahead

This regex:

/[aaaaa]/

is equivalent to:

/[a]/

So this regex:

[^{{}}]

Is equivalent to:

[^{}]

I am expecting it to match the entire block up to the first mismatched '}}'

Huh?

First, you said this:

I am using the following to extract data with a {{Infobox ... }} block, with the catch being that there might be {{ ... }} blocks within it.

Then you said this:

The problem is that this does not match if I have {{ something {{{ text }}} }} in my content ...

Here is a regex that will 'match' both:

/.*/

To ask a regex question that is specific enough to get a relevant answer, you need to post:

  1. An example of your text.
  2. The exact text you want to end up with.

Note that for 2), you DO NOT post a description of the text that you want to end up with. Why? Because descriptions are usually gibberish, and at best they are subject to different interpretations. If required, repeat steps 1) and 2) as many times as needed to highlight the twists and turns in the text you need to match.
