Thank you for your answer.
The green example was just for testing. My real example is similar to yellow on a header parameter since i have a client sending me the value of sip.instance between quotes and i can't identify the value when it is quoted. 

Example : Contact:<sip:user@domain>;+sip.instance="<urn:uid:00000000000000>"

It seems to me be a valid sip parameter, but if it's not i'll warn the client

Hello,

the values of parameters can be quoted or unquoted, depending on the format (e.g., URI parameters have to be unquoted). If they start with a quote, then it has to be terminated with the same quote and then the value is in between the quotes. The {param} transformation is using the same parser as for parameters in SIP message.

Now, I am not sure if quote is allowed in an unquoted parameters like green, the grammar in SIP specs has to be checked...

Cheers,
Daniel

In the green example the "" are printed, but on the yellow example it is not.

Greetings,

 

I'm testing some parameters actions and i found a weird behaviour

 

This is my code for the test :

 

$var(Parameter_List) = "blue=twelve;green=twe\"lve\";yellow=\"twelve\"";

xerr("Parameter List = $var(Parameter_List)");

xerr("Value of Parameter blue = $(var(Parameter_List){param.value,blue})");

xerr("Value of Parameter green = $(var(Parameter_List){param.value,green})");

xerr("Value of Parameter yellow = $(var(Parameter_List){param.value,yellow})");

 

 

The printed logs are the following :

ERROR: <script>: Parameter List = blue=twelve;green=twe"lve";yellow="twelve"

ERROR: <script>: Value of Parameter blue = twelve

ERROR: <script>: Value of Parameter green = twe"lve"

ERROR: <script>: Value of Parameter yellow = twelve

 

I have also tried setting the string as :

$var(Parameter_List) = 'blue=twelve;green=twe"lve";yellow="twelve"'; 

But the results were similar

The "" are not recognized in some scenarios. Is this intended behaviour or should i submit it as a bug?

 

 

Best Regards,

 

Duarte Rocha
