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();
                //...
             }

Here's a tiny excerpt of some DOM parsing in PHP. I haven't don't much. 

 

Assuming you have saved the XML to $mapXml: 

 

$doc = DOMDocument::loadXML($mapXml);
        $mapNode = $doc->getElementsByTagName('ResourceId')->item(0);
        $mapName = $mapNode->nodeValue; 

 

Of course you probably need a loop to determine vary item(x). Not sure how
you do a while or find the max item(x) in XML.

Thanks Scott. Beat me to it. 

 

With the DOM parser you can search on the <ResourceId> tag and parse the
name of the map, here's an example value: 

 

<ResourceId>Library://QE_Data/Maps/SDF2.0_Dublin_CA83IIIF.MapDefinition</Res
ourceId> 

 

By the way it's Library:// 

 

// and not \\ just in case you missed that too.

In Java you can do something like this, creating a ByteArrayOutputStream and
then displaying that stream back as a String.


 ByteArrayOutputStream bos = new ByteArrayOutputStream();        
        byte[] byteBuffer = new byte[1024];
        int numBytes = byteReader.Read(byteBuffer, 1024);
        while(numBytes > 0)
        {
            bos.write(byteBuffer, 0, numBytes);
            numBytes = byteReader.Read(byteBuffer, 1024);
        }
        System.out.println(bos.toByteArray());


or you can get straight XML back from the MgByteReader, and then parse that:

  MgByteReader byteReader =
resourceService.EnumerateResources(resId,-1,MgResourceType.MapDefinition);
        String xml = byteReader.ToString();
   //  ...parse the xml via the DOM

hope this helps

Did that, but I get an MgByteReader object with no clue how to iterate.isn't
there a count/getitem method I could use or do I have to convert to a string
and Parse or something?

Try MapDefinition 

Case sensitive.

Pulling my Hair out I'm just trying to get a list of Mapdefinitions in the
Library:\\ 

I tried doing EnumerateResources on Library\\: with -1 and Mapdefinition,
but can't find an API way to get the names..Am I way off target here?
