QXmlStreamReader looks perfect for parsing LyX XML. QXmlStreamWriter looks perfect for writing it. I seriously doubt these will be unstable. Note that writing [valid] XML is much easier than reading it, so you could write your own stream writer. Reading actually isn't that hard either -- it helps to not support external entities (and, indeed, QXmlStreamReader doesn't). But really, XML itself is stable, and these libraries look well-matched up to XML (as one would expect), so I see no reason for there to be backwards incompatible API/ABI/semantic changes to them. Removal, OTOH, is much harder to foresee, but in that case you can just write your own streamers. Nico --
