regular expression

Hi all,

short question concering a regular expression pattern.

Code:

line = '1	"bla \"bla\" $%1!\n" $ just "a" test'
rexEntry = re.compile('^(\d+)\s"(.*)" *(\$.*)?')
mo = rexEntry.match(line)
print mo.groups()

With this I get the following result:

Code:

('1', 'bla \"bla\" $%1!\n" $ just "a', None)

But that what I want is:

Code:

('1', 'bla \"bla\" $%1!\n', '$ just "a" test')

Can someone give me a hint?

Thanks in advance!

This works for me... with the example above.

Code:

^([0-9]+)\t"(.+)"\s(\$.+?)$

Note: If you use this with match you shouldnt have to have the ^ at the beginning.

Hope this helps,

Mark.

Thank you for your reply.
Your code works for the example above but there are still cases in my problem that can't be matched with this pattern.
I solved the problem by specifying two patterns and combined them with |
That works now for me...

... I always use ^ if I want to find a string at the beginning. I know that just "match" will do it also but ...
... I don't know ... habit
