not working for comma or accented charactes

[Koli14]

The convertXML function does not work if my XML contains Hungarian characters, or commas.
My XML looks like:

<?xml version="1.0" encoding="UTF-8" ?>

But if I remove characters like , ü ó ú ő á é, then it works.
I get the following error message, if it contains the characters above:
