Question

I’m currently in the process of creating an android app that displays a biological key for species identification. At each step of the key, two or more images with text are displayed as buttons that describe some features, which on clicking, take the user to the next corresponding node. The key is defined in an XML file. A simplified snippet is shown below. I have created a large XML file, and it is becoming unwieldy. I was wondering if there was a tool in which I could graphically represent my XML file and the associations between nodes. Ideally, I would like to be able to edit, add, and delete nodes.

I know this is a big ask, but I am willing to create a tool to do this task. Just thought I better ask before I reinvent the wheel.

Cheers,

Neil

In the end I created my own tool using Qt, using the following as a guide: http://doc.qt.nokia.com/4.7-snapshot/itemviews-simpledommodel.html
