The first code :

// Read the MapDefinition into an XML DOM document object.

$md = " Library://XXX/$mapName.MapDefinition "; // TODO Constant!

$mdResourceId = new MgResourceIdentifier($md);

$mdReader = $resourceService->GetResourceContent($mdResourceId);

$mdXml = $mdReader->ToString();

$mdDomDoc = DOMDocument::loadXML($mdXml); 

 

// Add a new MapLayer

$targetNode = $mdDomDoc->getElementsByTagName("MapLayer")->item(0);

// Save the updated MapDefinition

// Now, update the MapDefinition.

// Prepare the updated XML to be written out to the session.

$wlupdatedXml = $wlDomDoc->saveXML();

// Create a temporary WebLayout

// Write the updated WebLayout to the session.

// Redirect to the Ajax viewer.
