Hi,
Transformation {param.value, param_name} returns incomplete or empty values
when parameter value contains comma (,).
See next example:
*$avp*(my_var)="a=val_a1,val_a2,val_a3;b=val_b";
in next transformations:
$(*avp*(my_var){param.value, a}) returns 'val_a1'
$(*avp*(my_var){param.value, b}) returns empty string
Seams that comma in parameter value conflicts with semi column separator.
Is this bug or wrong documented?

New subject: Parameters list transformations comma and semi column conflict
Hello,
Parameters to SIP headers are ';' separated. ',' is used to concatenate
multiple headers onto a single line. The {param...} transformation is
intended to process SIP header parameters.
However, there is a new feature in Kamailio 4.1 (currently in a
pre-release/testing phase) that allows you to specify the delimiter value.
That may do what you require.
Please see:

New subject: Parameters list transformations comma and semi column conflict
Hi Peter,
I tried transformation {pram.value,name['delimiter']} for 4.1.0-pre0:
$(*avp*(my_var){param.value, a, ';'})
and got parsing error:
0(32237) ERROR: pv [pv_trans.c:2386]: tr_parse_paramlist(): invalid
separator in transformation: value,a,';'}
0(32237) ERROR: <core> [pvapi.c:1586]: tr_lookup(): error parsing
[{param.value,a,';'}]
0(32237) ERROR: <core> [pvapi.c:972]: pv_parse_spec2(): bad tr in pvar name
"avp"
0(32237) ERROR: <core> [pvapi.c:998]: pv_parse_spec2(): invalid parsing in
[$(avp(my_var){param.value,a,';'})] at (4)
If set delimiter without quotes (documentation isn't clear for this), e.g.
$(*avp*(my_var){param.value, a, ;})
then no parsing complain. But, get same wrong results, for parameter value
not quoted if contains ','.
Is this expected behavior?

Seudin

New subject: Parameters list transformations comma and semi column conflict
Hello,
There should be no '' around the delimiter. That's why the documentation
says "single character". The '' in the documentation are there because
the
convention in the documentation is to surround literal examples in '' - you
can see this throughout that wiki-page.
I neither expected comma to work as a delimiter nor expected it not to
work. However, I did think there was a chance it would. I now suspect
comma is one of the few delimiters that won't work and this is probably
because the transformation parser doesn't handle them as it interprets them
as the separator for transformation arguments.
As was pointed out these transformations were originally for parsing SIP
header and URI parameters which are always delimited with semi-colon. I
extended them to take an optional delimiter so that they could be used to
parse HTTP URI parameters which are delimited by ampersand. I would never
expect to have comma delimited parameters in SIP or HTTP, so I did not
consider comma when I extended the transformation.
Regards,
Peter

New subject: Parameters list transformations comma and semi column conflict
Hello,
iirc, the parser beneath is the one used for headers and I think the
parser stops because comma is separator for headers.
Can you try with parameter values in between quotes?
Cheers,
Daniel
