Hi friends,

we need to run MathML inside \sym (see below). Is there a way to solve the error "! Argument of \buff_gobble has an extra }."

You can’t use \startbuffer … \stopbuffer in other commands but with \setbuffer there is a command which can be used here.

\sym{\setbuffer … \endbuffer\processxmlbuffer}

great, thanks. but this immediately gives the next error: "invalid xml file - parsed text" what's wrong with the code below?
