LoadXML error (with parameter passing)

I have 1 funny problem.
Trying to load data into grid using load XML.
If I use
gridQString = “new_import_load.asp?file_name=testdata2.txt”; it works fine.
but if I use
gridQString = “new_import_load.asp?file_name=C:\Inetpub\wwwroot\abc\testdata2.txt”; it will give me error,
Error Type : LoadXML
Description : Incorrect XML

Any ideas what went wrong here

mygrid = new dhtmlXGridObject(‘gridbox’);
mygrid.setImagePath(“dhtmlx/dhtmlxGrid/codebase/imgs/”);
mygrid.setHeader(“Name, Email, Designation”);
mygrid.setInitWidths(“150,150,*”);
mygrid.setColAlign(“left,left,left”);
mygrid.setColTypes(“dyn,txt,ed”);
mygrid.setColSorting(“str,str,str”);
mygrid.init();
mygrid.setSkin(“dhx_skyblue”);
gridQString = “new_import_load.asp?file_name=C:\Inetpub\wwwroot\abc\testdata2.txt”; mygrid.loadXML(gridQString);

I receive this in the called program,
C:Inetpubwwwrootabcestdata2.txt instead of C:\Inetpub\wwwroot\abc\testdata2.txt

any ideas why?
