It does say xmlReaderForFile after all, doesn't it?

Why aren't you just using xmlReaderForMemory[^]

Up-voted with my 5.
I had to remove my answer. I certainly failed to see the question was about C, thanks for your note.

Okay, that's very kind of you.
Only problem is I can't vote for your answer. There were some good points contained within, but alas - it is all lost to the ether!
Best regards.. :)
