Regex Question

[Frank Koshti]

Hey Steven,

Thank you for the detailed (and well-written) tutorial on this very
issue. I actually learned a few things! Though, I still have
unresolved questions.

The reason I don't want to use an XML parser is because the tokens are
not always placed in HTML, and even in HTML, they may appear in
strange places, such as <h1 $foo(x=3)>Hello</h1>. My specific issue is
I need to match, process and replace $foo(x=3), knowing that (x=3) is
optional, and the token might appear simply as $foo.

To do this, I decided to use:

re.compile('\$\w*\(?.*?\)').findall(mystring)

the issue with this is it doesn't match $foo by itself, and requires
there to be () at the end.

Thanks,
Frank
