Some more tests with IE 7.0, I don't know why but when reading a KML IE uppercase the tag "Multigeometry" while Firefox lowercase it.<br><br>So, I've change the "parseFeature" method of the KML format, it seems to work OK with both IE and Firefox.<br><br><br>/**<br> * Method: parseFeature<br> * This function is the core of the KML parsing code in OpenLayers.<br> * It creates the geometries that are then attached to the returned<br> * feature, and calls parseAttributes() to get attribute data out.<br> *<br> * Parameters:<br> * node - {<DOMElement>}<br> *<br> * Returns:<br> * {<OpenLayers.Feature.Vector>} A vector feature.<br> */<br> parseFeature: function(node) {<br> // only accept one geometry per feature - look for highest "order"<br> var order = ["MULTIGEOMETRY", "Polygon", "LineString", "Point"]; <br> var type, nodeList, geometry, parser;<br> for(var i=0; i<order.length; ++i) {<br> type = order[i];<br> <br> this.internalns = node.namespaceURI ? <br> node.namespaceURI : this.kmlns;<br> nodeList = this.getElementsByTagNameNS(node, <br> this.internalns, type);<br> if(nodeList.length == 0) { <br> nodeList = this.getElementsByTagNameNS(node, <br> this.internalns, type.toLowerCase());<br> } <br> if(nodeList.length > 0) {<br> // only deal with first geometry of this type<br> var parser = this.parseGeometry[type.toLowerCase()];<br> if(parser) {<br> geometry = parser.apply(this, [nodeList[0]]);<br> } else {<br> OpenLayers.Console.error("Unsupported geometry type: " +<br> type);<br> }<br> // stop looking for different geometry types<br> break;<br> }<br> }<br><br> // construct feature (optionally with attributes)<br> var attributes;<br> if(this.extractAttributes) {<br> attributes = this.parseAttributes(node);<br> }<br> var feature = new OpenLayers.Feature.Vector(geometry, attributes);<br><br> var fid = node.getAttribute("id");<br> if(fid != null) {<br> feature.fid = fid;<br> }<br><br> return feature;<br> }, <br><br><br>Regards,<br><br><br>Benoit Pesty.<br><br><blockquote><hr>From: tchule@hotmail.com<br>To: dev@openlayers.org<br>Date: Wed, 7 Nov 2007 17:09:24 +0000<br>Subject: [OpenLayers-Dev] Multipolygon and KML<br><br>

Hello,<br><br>I'm currently trying to play with the KML Format and I have in the data I'm using some Multipolygon objects.<br>I know that its not completely supported yet and that I should submit a patch with a real test case but I'm very short on time on my projet and I've done a few ugly hacks that make things work with Firefox (but not IE yet).<br><br>So, I'm just posting this in case someone have more time than me to look at this subject.<br><br>For the export, the "buildGeometry.collection" method in the KML format is not working because "this" is refering to the "buildGeometry" object instead of the "KML" object.<br>I've added an ugly "var obj = new OpenLayers.Format.KML();" to make things work, but it's probably not the best way to do.<br><br><br> /**<br> * Method: buildGeometry.collection<br> * Given an OpenLayers geometry collection, create a KML MultiGeometry.<br> *<br> * Parameters:<br> * geometry - {<OpenLayers.Geometry.Collection>} A geometry collection.<br> *<br> * Returns:<br> * {DOMElement} A KML MultiGeometry node.<br> */<br> collection: function(geometry) {<br> var obj = new OpenLayers.Format.KML();<br> var kml = obj.createElementNS(obj.kmlns, "MultiGeometry");<br> var child;<br> for(var i=0; i<geometry.components.length; ++i) {<br> child = obj.buildGeometryNode.apply(obj,<br> [geometry.components[i]]);<br> if(child) {<br> kml.appendChild(child);<br> }<br> }<br> return kml;<br> }<br> },<br><br>For the import, the parser doesn't seems to support the presence of the "id" attribute in the Placemark tag, i've commented the following line of the "createPlacemarkXML" method :<br>placemarkNode.setAttribute("id", feature.fid);<br><br>And last thing, the "MultiGeometry" node is not found by the parser, i've put the node names in lowercase in the "parseFeature" method :<br>var order = ["multigeometry", "polygon", "linestring", "point"];<br> <br>I'll try to correct this for Internet Explorer too and to give more informations ...<br><br>Best Regards,<br><br>Benoit Pesty.<br><hr>Windows Live Hotmail and Microsoft Office Outlook – together at last. <a href="http://office.microsoft.com/en-us/outlook/HA102225181033.aspx?pid=CL100626971033" target="_blank">Get it now!</a>
