Here is a literal translation with a few more details.
However if you try to use the clarion ole control for xml you are likely to
comit suicide before the project is over.
It would be much smarter to generate the interfaces and do it right. I
wrote the code below a long time ago in c5b
then abandoned it and went early binding.
hence I lived.
