SIXX works very good to write/read objects, but it means you have to give up on your own xml schema.

And it's almost to easy to use:

	sws := SixxWriteStream newFileNamed: aFileName.
	sws nextPut: (self objectsToExport).
	sws close.

	srs := SixxReadStream readOnlyFileNamed: (aFileName).
	objects := OrderedCollection new.
	[srs atEnd] whileFalse: [objects add: srs next].
	srs close.
