Hi there,

I do work on following regex:
^(.*)_a[0-9](.*).htm$

This should be valid for "test_a9393.htm", but not for "9393.htm" as 
ther is no leading _a infront of the number.

Unfortunatelly this also works for the 9393.htm file. Can somebody give 
me a hint why the regex also is true for text that does not start with 
_a infront of the number?

Thank you for any help,

Merlin

How about this:

(\w)+(_a){1}(\w)+\.htm$

Worked for me :)
