regex help : check contents of capturing group

I have the following string:


Using a regex in an apache rewritecond I'm wanting to extract the value assigned to test1


Open in new window

this results in 3 capture groups:

1) op=func
2) abcd
3) &test2=test

which is great, I can use all these elements in my apaache rewriterule

However, I'm only interested in finding a match where capture group 2 (in this case, "abcd") contains a lowercase character.  This string can be any length.  If the value was "ABCD" I dont want to find a match.

How can this be done

Yeah, I did not pay attention. My regex checks if there is a lower case character in group 3.
