CodeMirror might do what you need. BaseX uses CodeMirror in its DBA web app to allow in browser editing of XQuery.
Another option, if your budget can support it, oXygen can be enabled to run in a browser.

Subject: [CODE4LIB] Online XML editing library (JQuery?)
I know there are several nice HTML libraries for editing HTML online, including source views that help you close brackets and do syntax coloring on the tags.
Is there an equivalent for displaying and editing raw XML online? I would prefer if it was something like a JQuery library, but would take anything. So far I am coming up empty on my search.
We are adding a native TEI component to SobekCM and one option is to allow the user to edit the raw TEI directly through the web interface. But, it is all an uncolored mass of text at the moment.
Thanks in advance!
