BaseX already looks/feels like a program I am going to enjoy using, even with the general challenge that I don't know enough about xQuery. I would welcome suggestions for anywhere to find a friendly introduction!

My first specific challenge is trying to under the syntax for replace. In the code, I've managed to retrieve a single xml document where <title> contains "35. Andan" … I made a copy/paste error, and in this document the value of title should be '35. Andantino' instead of '35. Andantino mesto'. My experiment is obviously incorrect, so I'd welcome tips on what's wrong with it.

//score[contains(title, '35. Andan')]//title
replace value of (title) with '35. Andantino'

Thanks in advance!
