TileMapServiceImageryProvider can't handle casing differences in tilemapresource.xml

We use getElementsByTagName to retrieve values from the document, but that function is case-sensitive for XML documents, unfortunately. What we can do instead is iterate the nodes in the document and check the node names with a case-insensitive regex.

I'm picking this one up.

Just to make sure I understand... As an example, should I replace:

var format = xml.getElementsByTagName('TileFormat')[0];

With something like:

var parseTagName = /tileformat/i;
var nodeList = xml.getElementsByTagName("*");

for(var i = 0; i < nodeList.length; i++){
  if(parseTagName.test(nodeList.item(i).nodeName)){
    format = nodeList.item(i);
    break;
  }
}

Or is there a better way to do this?

Yes, your approach looks reasonable. You might want to iterate through xml.childNodes instead of querying for all elements. Check the document structure as you go, for example, you can find the TileSets element first, then find the TileSet elements inside. The current code doesn't necessary process the data in document order.

I believe this issue can be closed.

Yep, thanks for addressing it, @Andre-Nunes!
