Very recently, in one of my previous contracts, I had to develop a tool to easily convert an XML flux to a JSON structure and I made a little XML to JSON Parser library available on Github: https://github.com/Zedenem/XMLParser
It is the second of my libraries to be made available on this really select iOS Controls site ! The first one was a take at making a circular UISlider (https://www.cocoacontrols.com/controls/uicircularslider) and there is more to come.
If you wonder when to use a parser like this one, here is a summary of the context where I thought it was necessary to program it :
I was working for a client’s iOS app that was making a lot of use of REST Web Services, getting and posting JSON requests both to display datas and interact with the server. At some point, I discovered that part of the Web Services weren’t conforming to the global specification and were sending back XML data structures instead of JSON.
No one knew about it when we first conceived our app data model and the problem was that I had to use the XML structured datas the same way as I used the JSON ones (both when displaying it and when posting requests to the server). Given the state of the project and the available time, I decided that it was better not to do specific work dealing with the XML and better try, as soon as I get it from the server, to convert it to JSON and “hide” the complexity behind a conversion parser.
That’s how the XMLParser library was born.
If you want to know more about how it is built and how the conversion is made, there is a README file inside the Git Repository: https://github.com/Zedenem/XMLParser/blob/master/README.md
