[mapguide-users] Finding list of Mapdefinitions

[Scott Reisdorf]

And heres some parsing of XML in Java:

 MgByteReader byteReader = 
resourceService.EnumerateResources(resId,-1,MgResourceType.MapDefinition);
        String xml = byteReader.ToString();

           DocumentBuilderFactory factory = 
DocumentBuilderFactory.newInstance();
           DocumentBuilder builder = factory.newDocumentBuilder();
           Document document = builder.parse(new InputSource(new 
StringReader(xml)));
          
           NodeList nodes = document.getElementsByTagName("ResourceId");
           for(int i=0;i<nodes.getLength(); i++) {
               Node resNode = nodes.item(i);
               String node = resNode.getFirstChild().getNodeValue();
                //...
             }
