1. XmlStream in your example emits other events than 'data'
2. the endElement handler, is this the right signature? please check the
doc/code of the XmlStream on this point
besides this points i guess this would work IF XmlStream implements the
node core Readable:
var xml = new XmlStream(response, 'utf8');
xml.on('endElement: endmarker ', writetoDB);
function writetoDB(input) {
console.log('i want to arrive here first upon receipt of the xml
endmarker');
db.create(input, function(err){
if(err) {
// do error handling here
return
}
console.log('create complete');
console.log('action this second');
xml.resume()
});
}
