Ok. I would like to distinguish the markers depending on the state (département in French) they are attached. Now, I only search for locations crossing two xml files and display them. I'd like to do something more complex : - on load, show all the markers (only at a certain zoom level --> that's why I use GMarkerManager) - when a click event is detected on one of the three polygons (each polygon matching a state), an infoWindow appears and a zoom in happens (lines 167 and 168). - I'd like to display only the markers of that state ; in order to do that, I've added an attribute "dep" in my villesIMG.xml (I don't feel comfortable dealing with regular expressions to use the two first numbers of the cp attribute) wich takes one of three possibilities. If a click event happens on polygon 0 (polys[0] corresponding to the state of Corrèze then display only the markers of Corrèze (atribute dep ="19") and hide the markers of the others states. So I figured I need to add a conditional loop in my request on villesIMG.xml to create an array of markers for each state and then decide what markers I use. I'm not sure if I'm clear about my intentions here. If you need more explanations, don't hesitate.
