XML serialisation for saving settings
lazarus / 8-Other

----------------------------------------------------------------------

I'm used to using a storage object for saving settings to reduce
duplicate code - rather than each new setting needing to be added in
the variable it's used in, the read method, the write method and the
help method(s) it's just added to the storage object. That storage
object is then streamed in and out as part of program
startup/shutdown. The XMLCfg/XMLConf duplicate units only seem to
support the code-intensive way.

There's a heap of stuff in lazarus/fpc, but I'm struggling to find
documentation and make it work - I'm effectively using grep instead of
help. The xmlstreaming example is useful and I have a derivative of
that  working using laz_XMLStreaming, but there's a lot of overhead (I
need a helper class purely to hold OnFindComponentClass, for example)
that I don't think should be there. I suspect I'm using internal Laz
code that's way more complex than i really need, but i can't see a
simpler way with what's there.

Specifically I'm looking for SaveObjectToXML and LoadObjectFromXML
procedures that accept just a filename and a TPersistent reference to
load or save. Any suggestions much appreciated.
