XML "folding" mode

[leo]

hi there

want to do some editing on text data content in xml files. how can emacs
help me?

i think about a xml-mode which hides or "unfolds" the xml tags only showing
the content data. it would make it much easier to edit this stuff.

i found the emacs lib xml.el, but that doesn't seem to provide a mode or so.

any idea is appreciated.

thanks, leo
