Okay, let me try again. I need to end up with a string that C++ can
swallow. The way I have it coded now it will find
match(0): href="http://someurl/page.html";
match(1): href
match(2): ="http://someurl/page.html";
I don't believe this is right and I suspect it has something to do with the
"r" in front of the third line. Can someone tell me what the r does?
I found that whitespace is really [ \r\t\n].

I think % are not comments (because the first '(' on the second line
matches the last ')' on the same line). They might just be pattern
replacers...
I guess the one-liner shuld simply be
attrfind = re.compile('[%s]*([a-zA-Z_][-.a-zA-Z_0-9]*)' % string.whitespace
+ ('([%s]*=[%s]*' % (string.whitespace, string.whitespace)) +
r'(\'[^\']*\'|"[^"]*"|[-a-zA-Z0-9./:+*%?!\(\)_#=~]*))?')
or maybe just add parens around each line :
attrfind = re.compile(('[%s]*([a-zA-Z_][-.a-zA-Z_0-9]*)' %
string.whitespace) + ('([%s]*=[%s]*' % (string.whitespace,
string.whitespace)) +
(r'(\'[^\']*\'|"[^"]*"|[-a-zA-Z0-9./:+*%?!\(\)_#=~]*))?'))
