XML to JSON API Proxy for Quick Mash-ups
While building our company dashboard, which was mentioned in our previous blog post on SVG with Raphael, I came across a problem with the project management tool we use, Pivotal Tracker.
The Pivotal Tracker API is only in XML, which means you can't do cross-domain requests and access the API via javascript. This meant that, if I wanted to extract data about the status of our user stories, I would have to do it on the server side. As everything so far had been done with javascript on the client side, I was reluctant to start making things more complicated. I contacted Pivotal, who said they might think about adding JSON at some point, but I didn't want to wait for them to sort it out. Instead, I built a quick API proxy that allows you to make a request to a XML API and get back JSON. So, now, I can do this in my javascript: It will proxy the GET request to the API and convert the XML response into JSON, via http://xml2json.heroku.com (supports JSONP). I've put the code on GitHub http://github.com/bitzesty/xml2jsonp in case anyone else needs to do the same thing.

It seems it ignores additional parameters started with &num_posts=2 for example.

Yea I have noticed the same thing... can't do much if you can't pass params

Actually... You have to use object syntax for the data param when passing additional parameters to $.ajax ... example $.ajax({
type: "GET",
url: 'http://xml2json.heroku.com',
data: {url : 'https://www.pivotaltracker.com/services/v3/projects/'+projectId+'/iterations/current?token='+trackerToken+'&limit=50'},
dataType: 'jsonp',
success: function(data) {
console.log(data);
}
});
This is because their code only grabs the url params and the callback param
