<div dir="ltr">Hello,<div><br></div><div>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.</div>
<div><br></div><div>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.</div>
<div><br></div><div>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.</div>
