In-place replacement for xml2js parseString. This is about 20x-30x faster and makes use of the rapidxml C++ library.
Run npm install fast-xml2js
Simply replace
var parseString = require('xml2js').parseString;
with
var parseString = require('fast-xml2js').parseString;
Then call it like so:
parseString('<some_xml>', function(err, result) {
console.log(result);
});
