ask for a RE pattern to match TABLE in html

[oyster]

that is, there is no TABLE tag between a TABLE, for example
<table >something with out table tag</table>
what is the RE pattern? thanks

the following is not right
<table.*?>[^table]*?</table>

Why not use an HTML parser instead? Try lxml.html.

Stating it differently: in order to correctly recognize HTML
tags, you must use an HTML parser.  Trying to write an HTML
parser in a single RE is probably not practical.

s/practical/possible

It isn't *possible* to grok HTML with regular expressions. Individual
tags--yes. But not a full element where nesting is possible. At least
not properly.

Maybe we need some notes on the limits of regular expressions in the
re documentation for people who haven't taken the computer science
courses on parsing and grammars. Then we could explain the necessity
of real parsers and grammars, at least in layman's terms.
