$$('myform').parse(text,'xml') not work

Hello everyone, recently I’m starting to develop dhtmlxtouch, have had good progress on my computer, however when I opened the page for the first time in a android device (motorola tablet) with firefox, the application does not refresh the forms through the method parse ().
I thought the problem was but it was not like ajax, browser on any PC working properly, this is the example:

var result = dhx.ajax (). get (“data-request”, “iu =” + iu + “&id =” + cvesolicitud + “& it =” + Math.random (), function (text) {
alert (text) // works well
$$(‘fredit’). parse (text, ‘xml’);
alert (“hello”) // does not work

});
any ideas?
Thank you very much.

I’m sorry, I found the error.
The error is in the structure of the xml.
I did not find documentation of the structure of the xml, but recently I see that all the examples are … </ item> </ data>
Do not place the tag
Does anyone know where I can find documentation of the data structures used by the methods "load,parse,etc?
