Incorrect XML on IE but not in Firefox

Hello, I’m using PHP script to generate XML string for 2 grids, and jquery to execute that PHP script. If the response from PHP begin with 1 first grid is filled with dhtmlxGrid.parse method and if response begin with 0 second grid is filled… In Firefox this works fine, but (of course) in IE not. Something curious is that I alert the response from PHP and is as follows:

FIREFOX:
117106GANCHO SENC MAGNA CR161710617106-SGANCHO SENC MAGNA S2017106-S

IE:
117106GANCHO SENC MAGNA CR161710617106-SGANCHO SENC MAGNA S2017106-S

First of all in IE row, cell… tags are in uppercase; but I dont think that is the problem.
The weird thing is that id for each row is double-quoted in Firefox but is not in IE, in PHP code that generates that XML string i do especify double quotes.

Can you help me please?? :neutral_face:

That may be reason of the problem.
Try to open generated xml in the IE. If xml is incorrect browser will point you to the incorrect symbol\row.
