Dear,
I have some trouble to extract from XML file to a tab some Lat Lng
points.
On the code bellow, I create a tab "pointsparcours" that will contain
all the coordinate of the XML file.
I use pointsparcours.push(pts[i]); that work fine at this point
(alert(pointsparcours[0]); show me that the coordinate are well
pushed).
The problem is that I can't get this tab data out.
The last line alert(pointsparcours[0]); give me an "undefined" alert
message.
How could I get this tab with data for an external use ? (...if
possible).
Thanks !!
