i have a project to be completed asap...and i have been working day and night on it...

i have to create a map which reads the markers frm an xml file and displays them on the map...after which the user creates a polygon..all the markers within the polygon turn green and the rest stay red...

below is the code..which i have managed to edit..for the time being ... one marker is being read but nt from the xml file...its thru a variable point and them getting stored in the marker...can i know how and where to insert the xml file..???
