Parsing XML in shell extension

[Jay Strict <jay strict posteo de>]

Hello List,

thanks for your help in the last weeks on some gnome-shell extension
questions.
I have since written a small Gnome Shell extension for controlling the
Syncthing [1] daemon. The extension can be found on GitHub [2] and on
the official Shell Extension Website [3].

Now I want to add some features.


1) In the Shell Versions array, I specified "3.16" as a working version,
since that is the Gnome Shell version that I use for development.
I would like to add older versions as well. How do I figure out, which
versions does my extension work with?


2) I want to read and parse the XML file that Syncthing uses as its
configuration file [4]. What is the best way to do so? I found the
Simple XML Subset Parser [5] in the GLib library and I think this would
be suitable, as the config file does not look very complex.
I also found an older thread [6] about this topic, in which it was
suggested to use E4X. But E4X seems to be obsolete.
Are there better alternatives? Can Gjs do something like this?
