[OpenSIPS-Users] Strip prefix

[Ben Newlin]

Glad you got it working! It’s not immediately clear to me why the end of string anchor would be required on the subst_exp nor why it’s absence would cause the errors you were seeing. A bit strange.

Hello Ben, here is what works for me.

dpid = 17

pr = 0

match_op = 1

match_exp = ^770555.+

match_flags = 0

subst_exp = ^770555(.+)$

repl_exp = \1



$ sign did the trick.



Thanks so much for the support.

There’s a few issues.

1. You are missing a “.” in your match_exp. The way you have it written will only match repeating digit 5 after the prefix.
2. Your subst_exp is too greedy. The wildcards in the first grouping will make that grouping match the whole string, and there will be nothing left for the second grouping (or it won’t match at all because of the + in the second grouping, not sure). If you are trying to match a fixed-string prefix you don’t need wildcards for that. You also don’t need to capture that grouping, since you aren’t using it in the replace.

Try this:


dpid = 17

pr = 0

match_op = 1

match_exp = ^770555.+

match_flags = 0

subst_exp = ^770555(.+)

repl_exp = \1
