I'm not sure exactly what you mean by "AJAX/mainstream tools/controls" here, but if it is data intended as markup as opposed to text, then it is up to you to parse it and correctly separate it from the textual content. You will then generate correctly formed XML from the result. It's no more reasonable to just throw this mishmash directly at an XML processor and expect it all to "just work" than it would be to throw an MPEG4 file into it and expect the processor to come out with all the subtitles arranged by scene.
