Flex Builder MXML Files to Haxe Conversion

Question

I have a very large flex builder project that I need to port to Haxe. All of our actionscript files are converted using as3hx. I have read about HaxeUI, FeathersUI, and NME. Do any of these options make porting MXML files easy and not a complete rewrite of them? It's important to note that a lot of most of my MXML files contain a lot of CDATA.

I found that there is compiler of mxml for feathers specifically see: https://github.com/BowlerHatLLC/feathers-sdk/tree/master/modules/compiler/src/java/flex2/compiler/mxml Haxe can generate externs for Java libraries.

It's pretty easy to hand port as3 to Haxe, that CDATA just has some getters and setter changes needed, void to Void, changing the protect/private/public, and then using an injection library, https://github.com/jasononeil/dodrugs. You could probably create a macro to parse the xml component creations yourself.... or maybe rewrite project with simpler approach is best?
