5/9 - update of code attempting use solution.. still getting errors though. object reference. syntax element not right, , i'm guessing can't select first attribute want base off of it.

var doc3 = xdocument.load(xml_path2);             var elem = doc3.xpathselectelement("//tests/test[name='navigatorlaunch']");               if (checkboxnavigator.checked == true)             {                 elem.attribute("value").value = "1";             }             else             {                 messagebox.show("it not checked");             }             doc3.save("c:\\car_audition\\param.xml");

figured out easiest way me follows:

var doc3 = xdocument.load(xml_path2);             var elem = doc3.xpathselectelement("/tests/test[@name='navigatorlaunch']");              if (elem != null)             {               elem.attribute("value").value = checkboxnavigator.checked ? "1" : "0";             }
