[mapguide-users] Finding list of Mapdefinitions

[Dave Wilson]

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<
/ResourceId>
 
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?
