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 :-)

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...

Why not convert the reStructuredText to XML and parse that?

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.
