Divida la expresión regular en 2 grupos de captura

Ok, my previous questions were answered ... I have one more, this one is more difficult for me...


Right now this expression produces only 1 capture group as noted with ^() ; How would I do 2 capture groups for this URL? (for IIS regular expression rewrite)

What do you want to grab from the string? Post an example, and what you want to get out of it. -

Ok, you haven't answered my question. Please post an example of the text to parse, and explain which portions of it you want to match. -

oh sry. --- I want to grab ie. silverspring.md.domain.com and capture group example: {c:1} silverspring {c2} md -

You can do this by enclosing the relevant portions like so:

text    = "city.state.domain.com"
pattern = "^([^\.]+).([^\.]+).([^\.]+).([^\.]+)$"
match   = re.match(pattern, text)
# Returns: [ 'city', 'state', 'domain', 'com' ]

Note, BTW, that I made the simplifying assumption that you can have any possible values between the '.' characters. Also, in the future, you can always just split() on '.'. - Stephen Gross
