I am using spacemacs nXML mode to edit build.xml (java ant configuration file), the file is very long, how to fold and unfold it?

  • Here is a related link to some code folding for nXML-mode that I wrote up some time ago -- perhaps you could modify it to suit your needs. The title of the thread is How can I fold arbitrary tags with nxml-mode?: superuser.com/a/787030/206164 – lawlist Apr 15 '15 at 1:36

    Not really what you're looking for but set-selective-display function can help you hide/un-hide some part of your file based on the indention. Also, occur is probably the best way to go when editing a large file, IMHO. – Nsukami _ Apr 15 '15 at 1:42

You need to add this hook:

(add-hook 'nxml-mode-hook 'hs-minor-mode)

After that put this in your init.el file or somewhere it'll be loaded.

(define-key nxml-mode-map (kbd "C-c h") 'hs-toggle-hiding)

If you now press C-c h it will fold the xml at the element where your cursor is.

    I guess you need to have hs-minor-mode enabled too? Should perhaps be part of the answer. – Meaningful Username Apr 15 '15 at 9:45
  • This actually does nothing in my Emacs 24.3.1. Do I need a specific Emacs version? Or hide-show mode version? – wvxvw Apr 15 '15 at 12:32
  • I'm using emacs 24.5.1 with nothing special. You of course need to be in an xml. I'll have a look at what may be missing.. – cb0 Apr 15 '15 at 18:37
