Question

How can I, if possible at all, programmatically edit xml data in Emacs Lisp?

What I need to do, is to programmatically add new nodes into arbitrary locations in the xml:

<root>
  <child>
  </child>
</root>

(xml-add-element xml "hello" (xml-element-by-tagname xml "child"))

<root>
  <child>
    <hello></hello>
  </child>
</root>

---

Edit: I got as far as parsing the xml into a lisp structure and editing it with xml.el and dom.el, but now I need to turn the lisp structure back into xml data.

here’s my version for converting s-expressions created from xml-parse* functions back into xml strings. Hope it’s helpful!
