regex matching rst code block?

[Edward K. Ream]

Here is a little regular expression puzzle. I wish a regex that matches an
rst code block, that is,



'::' followed by a group of lines all indented by at least as much as the
first non-blank line following the '::'



My guess is that this is not possible. Can anyone prove me wrong

I'll assume you mean reStructuredText with 'rst'.

Why not convert the reStructuredText to XML and parse that?

Try

r":\s*\n(\s*\n)*((\s+).*?\n)(((\4).*?\n)|(\s*\n))*)"

Probably buggy and too complicated, but you didn't post a good test suite...

Because the problem arises for the jEdit syntax colorer whose most powerful
pattern matcher is a regex.

r":\s*\n(\s*\n)*((\s+).*?\n)(((\4).*?\n)|(\s*\n))*)"

Thanks for this. I'll try it out.
