Indenting XML documents with gEdit
gedit is a pretty cool text editor for the GNOME desktop environment.
The problem is that sometimes I found myself using it to edit XML documents but there is no way to pretty print them.
I found yesterday a quick solution to this problem thanks to the External Tools support in gedit and a small utility called xmlindent.
Once you have installed xmlindent click on Tools->External tools, and on the dialog enter the following informations:
Of course you can customize the options as you wish, the displayed configuration just indents the whole document and replace the unindented one.
To use it just click External Tools -> xmlindent.

If you don’t find the Tools > External Tools , it might just be that it has not been turned on (it is a plugin). Go to Edit > Preferences > Plugins and check that there is an entry for “External Tools” and that it is enabled. Following that the rest of this entry applies.
