Hey Ivan, Yes, I checked out this your link. But I don´t have success in transferring it to my own document. Here is what I got yet:
=> I perform a GetFeatureInfo-Request on "http://localhost:8080/geoserver/wms"; with INFO_FORMAT: 'application/vnd.ogc.gml'. => this is done via OpenLayers.loadURL("http://localhost:8080/geoserver/wms";, params, this, setHTML, setHTML); => my setHTML-function now looks like that: function setHTML(response){ var g = new OpenLayers.Format.XML(); var features = g.read(response.responseText); var url = g.getAttributeNS(features.documentElement, 'http://www.w3.org/2001/XMLSchema-instance', 'schemaLocation'); document.getElementById('nodelist').innerHTML=response.responseText; document.getElementById('urlOutput').innerHTML=url;} In this case it puts out the schemalocation in the urlOutput. But that´s not what I want to achieve. So the question is, how can i get other elements out of the XML like the ID for example. For that I have to competely understand what all those methods do which is not the case yet ;-). For example the read-method: does it read the content of an XML-File node by node? Or the getAttributeNS-method: What does features.documentElement (= the node) mean and why am I not able to refer to another name than 'schemalocation' (when I try url, which is an attribute in my layer it returns no result). thanks for your help Max Stephan Ivan Grcic-2 wrote: > > Hi, did you check out http://openlayers.org/dev/examples/GMLParser.html > > Function load takes ur xml data (which can be getFeatureInfo), and > gives it to parseData function, which parses all the features and > their attributes...its all you need ;) > And i suggest to make it in JSON format, its much lighter > > function load() { > OpenLayers.loadURL("gml/owls.xml", "", null, parseData); > } > > function parseData(req) { > g = new OpenLayers.Format.GML(); > html = "" > features = g.read(req.responseText); > for(var feat in features) { > html += "Feature: Geometry: "+ features[feat].geometry+","; > html += "<ul>"; > for (var j in features[feat].attributes) { > html += "<li>"+j+":"+features[feat].attributes[j]+"</li>"; > } > html += "</ul>" > } > document.getElementById('output').innerHTML = html; > } > > Cheers > > On Tue, Feb 3, 2009 at 9:09 PM, Max Stephan <[email protected]> wrote: >> >> Ok, that sounds like an idea. >> >> I´ve been reading a bit more about JavaScript-development in general.
