Client for Web Feature Service (Open Geospatial) for Axway Titanium
var Wfs = require("ti.wfs").createWFS("https://geodienste.hamburg.de/HH_WFS_Strassenbaumkataster","2.0.0");
Wfs.getFeature({
region : {
latitude: 53.53,
longitude: 10.0,
latitudeDelta : 0.05,
longitudeDelta: 0.05
},
typeNames : "app:Strassenbaumkataster"
}, function(e){
console.log(e.data)
});
And you will get:

Wfs.getFeature(xml, function(e){

If you want filter the request you have to use XML. In this case the first parameter is a xml string:
var xml = "<?xml version='1.0' encoding='UTF-8'?>

Generates a metadata document describing a WFS service provided by server as well as valid WFS operations and parameters
Returns a description of feature types supported by a WFS service
Wfs.describeFeatureType()
Gives you:
