You can understand the algorithm I used and implement in your own way. Here what I have done is I created a php script that analyzes your downloaded “xml” data and show you the encoded text.
You need a active webserver .You can also run an offline local host using softwares like phpmyadmin or etc.
The xml file must be named ‘plotMe.xml’ and must be present in the same directory where this php program stays.

You can send me you algorithm for review and your ideas to share in this post. Just add up your thoughts or codes in comment and I will put you here.
