RegEx is required for Wikipedia info box

Question

OK, so here is what I need:

• We have the full Wikipedia article XML file.
• We need an infobox section

I tried different things, but my main problem seems to be unable to match the "inner" curly braces. Any ideas (or any regex that you managed to make?)

For those of you who don't know what I'm talking about, here is a (somewhat abbreviated) example of what I'm trying to analyze: http://regexr.com?38299

(a part is required between {{Infobox ******* to its corresponding closing brackets ( }} ).

Answer 1

OK I understood!

Try the following:

 (?=\{Infobox)(\{([^{}]|(?1))*\}) 

Here is a working example:
