Looping through the features of a WMS layer<br></font><br></div><div><div></div><div class="h5">
<div></div><font size="2"><span style="font-family:arial,helvetica,sans-serif"></span></font>Hi,<br><br>I want
to get the map of Canada then loop through all provinces, in order to color them
differently (I'm going to create a new Vector layer for each province and apply
its own styleMap) :<br><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace">var wmsLayer = new
OpenLayers.Layer.WMS("Canada", "<a href="http://www2.dmsolutions.ca/cgi-bin/mswms_gmap" target="_blank">http://www2.dmsolutions.ca/cgi-bin/mswms_gmap</a>",</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">{</span><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace"> layers:
"bathymetry,land_fn,park,drain_fn,drainage," +</span><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace">

format: "image/png"</span><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace">});</span><br><br>So the question is
how to loop through the WMS layer features or "prov_bound" to retrieve each
province's geometry. <br><br>Thanks!<br>Francois<br><br><br><br></div></div></div>
