Thanks Trevor! (Also Ken). That seems to work very well.
The particular problem I was trying to solve was how to serialize
arrays with arbitrary keys and contents, such that they can be
shared across networks and platforms. I think I've found a solution
for my purposes, (though it won't be reliable with binary data), and
it involves building the xml without the xml library, and then using
the library to unserialize - though it fails if there is any "<?
xml..." header at all!
Mark,
For what it's worth I've been using the attached SerializeArray/
UnserializeArray handlers with relatively small arrays for a while now
and they seem to be working well enough for storing them in a database.
