If you are parsing user-defined strings like player names, you may want to convert special characters to their XML entities as a precaution beforehand, otherwise the result might be corrupted. private _escapeXML = { _this regexReplace ["&", "&amp;"] regexReplace ["<", "&lt;"] regexReplace [">", "&gt;"] regexReplace ['"', "&quot;"] regexReplace ["'", "&apos;"] }; private _name = '<A&M> Paul "Bear" Bryant'; private _escapedName = _name call _escapeXML; private _redName = parseText format ["<t color='#ff0000'>%1</t>", _escapedName];
