RE: [xsl] XML/XSLT reading

["Michael Kay" <mike@xxxxxxxxxxxx>]

XSLT can handle this without any problems, though you do need a driver
application of some kind to handle the returned form.

The display side is bread-and-buffer for XSLT, no problems here at all.

On the editing side, there are two minor complications:

(a) you will need a server-side script of some kind to handle the posted
request, extract the parameters, and invoke an XSLT transformation

(b) XSLT works by modifying the old version of the XML to create a complete
new version. This may be inefficient if the file is very large and you are
only changing one value; and you will also need to think about how to manage
the files as they change (for example, do you need to keep the old copy as a
backup, and if so, for how long).

However, neither of these is a serious obstacle.
