Hi! I have almost no experience with scheme, but I started a project just to test and play with the language. I use lizorkins sxml library(?) to parse some xml files. However I have som truble with the way it uses variables in sxpath. This code works: (define (get-title doc) (srl:sxml->xml ((sxpath "books/book[$i]/title/text()") (sxml:document doc) '[(i . 1)]))) But this dosen't: (define (get-title doc num) (srl:sxml->xml ((sxpath ""books/book[$i]/title/text()") (sxml:document doc) '[(i . num)]))) When I debug the code I can se that i changes to num after the evaluation of the xpath query, but I'm not sure if I use the debugger correctly since I've only playd with it today. What am I missing? I know that I jumped on a project thats maybe a bit to hard for my level but I like to learn that way and it often works, but this time I'm stuck. Sorry for the bad english, it's not my native language and I seldom write in it.
