How does this work ? It seemed to work for over here.
avp_subst("$avp(s:pai)/$avp(s:cli)","/<[[:blank:]]*tel\:([^[:blank:]]+)[[:blank:]]*>/\1/");

Hi Norman!
thanks - this works indeed. Now I wanted to tune it, so that it not
only removes spaces, but also tabs (according to posix this is
[:blank:]).
For positive matching it works:
/<[[:blank:]]*tel:([^ ]+)[[:blank:]]*>/\1/ --> OK
But if I add this to the "negative matching" it fails:
/<[[:blank:]]*tel:([^[[:blank:]]]+)[[:blank:]]*>/\1/ --> not OK
^^^^^^^^^^^^
Do I need a special syntax for this?
thanks
klaus
btw: I think escaping the colon is not necessary

Hi,
Hope the regex below helps you out.
avp_write("< tel:+43108 >", "$avp(s:pai)");
avp_subst("$avp(s:pai)/$avp(s:cli)","/<[ ]*tel\:([^ ]+)[
]*>/\1/");
xlog("L_NOTICE", "pai=($avp(s:pai)) cli=($avp(s:cli))\n");
pai=(< tel:+43108 >) cli=(+43108)

I tried ([^[[:blank:]]]*) but that did not worked
