regex

Have you found any good uses for regex other than class-maps? I recently
started using regex to sort access-list elements in bulky ASA policies.

Example:
sho access-list | i
(172\.)(1[68]\.|2[046]\.)(1\.|(99\.))(1[3,5-8]|8[0-4]|41|2[6-7]|118)

This works pretty well other than end of string. I find the ASA does not
process the $ well in any statement. Has anyone else experienced this?

Example:
In the above example the last octet can be any of the following:
13
15-18
80-84
26-27
41
118

That being said any configuration I use with $ still allows longer string
matches like 131, 151, 801... etc. Has anyone else worked with this and had
success with end of string?

Thanks,
Roger
