GXml.value() returns the text content of those nodes in a browser
independent way.
This should get that content:
var markers = xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++)
{
var x = GXml.value(markers[i].getElementsByTagName("x")[0]);
var y = GXml.value(markers[i].getElementsByTagName("y")[0]);
*** UNTESTED ***
Note that x and y will be strings and you probably will need to
convert them to numbers (parseFloat is one way).
