Or, if you prefer shorter, quick-and-dirty syntax closer to perl's approach:

match = re.search(r"<(tag1)>(.*)", line)
if match: variable = match.group(2)

Indeed. I second that.

Joel Hedlund enlightened us with:
> regexp = re.compile(r"<(tag1)>(.*)")

I'd go for

regexp = re.compile(r"<(tag1)>(.*?)")

Otherwise this:

line = "sometextothertext"
match = regexp.search(line) 

will result in 'sometextothertext'

No, but if you use a closing  instead of <\tag1> it does. You had me 
scratching my head for a while there. :-)

This should do it in python:


#!/usr/bin/python

import re

regexp = re.compile(r"<(tag1)>(.*)")
line = "sometext"
match = regexp.search(line) 

if match:
variable = match.group(2)



Good luck!

help in converting perl re to python re

[eight02645999]

hi

i have some regular exp code in perl that i want to convert to python.


if $line =~ m#<(tag1)>(.*)#
   {
 $variable = $2;
}

the perl code finds a line that matches something like

"sometext<\tag1>" in the line and then assign $variable the value
of  "sometext"

how can i do an equivalent of that using re module?
thanks
