regex help : check contents of capturing group

I have the following string:

op=func&test1=abcd&test2=test

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

^(.+)&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

Don't know if you can do forward lookups in .htaccess, but in this case you need it:

^(.+)&test1=([^&]+)(.*=.*(?=[a-z])+.*)$

Open in new window

Are forward lookups really necessary, this seems to work fine for me...

^(.+)&test1=([^&]*[a-z]+[^&]*)(.*)$

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