<DIV dir=ltr><FONT face=Verdana color=#000000 size=2>I've done something to allow a user to add a WMS on the fly.</FONT></DIV>
<DIV dir=ltr><FONT face=Verdana size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Verdana size=2>Here's a few clues :</FONT></DIV>
<DIV dir=ltr><FONT face=Verdana size=2>- I ask the user for the URL</FONT></DIV>
<DIV dir=ltr><FONT face=Verdana size=2>- http request to get the capabilities</FONT></DIV>
<DIV dir=ltr><FONT face=Verdana size=2>- from the answer to the getCapabilities, a pick up the title and the available layer(s) - something like :</FONT></DIV>
<DIV dir=ltr><FONT face=Verdana size=2></FONT> </DIV>
<DIV dir=ltr><FONT face="Courier New" size=2> var xmlFormat = new OpenLayers.Format.XML();<BR> var xml = xmlFormat.read(oHttpRequest.responseText);<BR> var capFormat = new OpenLayers.Format.WMSCapabilities_1_1_1();</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2> var cap = capFormat.read(xml);</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2></FONT> </DIV>
<DIV dir=ltr><FONT face="Courier New" size=2> // title<BR> myTitle=cap.service.title;</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2></FONT> </DIV>
<DIV dir=ltr><FONT face="Courier New" size=2> // layers</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2> for (var i=0; i<cap.capability.layers.length;i++)<BR> {</FONT></DIV>
<DIV dir=ltr><FONT face="Courier New" size=2> ...<BR> }<BR></FONT><BR><FONT face=Verdana size=2>- the user selects the layer(s) of interest (I use the ItemSelector to do so)</FONT></DIV>
<DIV dir=ltr><FONT face=Verdana size=2>- selected layer(s) is(are) added to the map (title previously extracted is used)</FONT></DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr><FONT face=Verdana size=2>biggest problem I had :</FONT></DIV>
<DIV dir=ltr><FONT face=Verdana size=2>- reading the XML returned for the getCapabilities with IE6</FONT> </DIV>
<DIV dir=ltr><FONT face=Verdana size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Verdana size=2>hope it helps</FONT></DIV>

<P><FONT size=2>Hello,<BR><BR>Is it possible with openlayers, that a user can add a WMS on the fly? Can OpenLayers be extended to act more like a geoportal? Or is it only meant for visualisation of preconfigurated wms?<BR><BR>Thanks!<BR>_______________________________________________________________________<BR>DSL zum Nulltarif + 20 Euro Extraprämie bei Online-Bestellung über die<BR>DSL Freundschaftswerbung! <A href="http://dsl.web.de/?ac=OM.AD.AD008K15279B7069a">http://dsl.web.de/?ac=OM.AD.AD008K15279B7069a</A><BR><BR>_______________________________________________<BR>Users mailing list<BR>Users@openlayers.org<BR><A href="http://openlayers.org/mailman/listinfo/users">http://openlayers.org/mailman/listinfo/users</A><BR></FONT></P></DIV></BODY></HTML>
