Regex help

[David A McInnis]

Is there a more efficient way to do this.  It seams like this is executing
the search twice.

    patt = re.compile("fax<br>\s*([0-9]{3,3}-[0-9]{3,3}-[0-9]{4,4})", re.I)
    if patt.search(tststring):
        faxnum = patt.search(tststring).group(1)
        print faxnum

I cannot just do
    faxnum = patt.search(tststring).group(1)

because if there is no match, it returns an error
