I came with a workaround to my problem after much debugging with SIPp.
To parse the following Contact header:
m: <sip:[EMAIL PROTECTED]>
...I am now successfully using the following workaround regexp:
<ereg regexp="[^ <].*[^>]" search_in="hdr" header="m:"
check_it="false" assign_to="3"/>
=> "In the 'm:' header, skip any space character, any opening angle
brace, capture any number of characters coming afterwards except a
closing angle brace".
1. SIPp's XML parser does not like < and > characters directly (e.g.
this conflicts with XML tag matching, somehow...), so using < and
> is necessary -- these are internally replaced by SIPp with < and >
later. What a hack.
2. I wasn't using a semi-colon (";") in each of these, causing 't'
(first character that matched) in " <sip:[EMAIL PROTECTED]>" to
be recognized at the end delimiter. This explains why I was getting the
following:
<sip:jeanno
3. For some dark reason, the simpler regexp didn't work either:
[^ <>]*
