First question. As I saw in sources, both hxt and haxml uses [Char]'s. this is very inefficient. I want to know, does any effective parser for haskell, written in haskell, exists. Efficient means using ByteString to store strings and possibly building representations that shares one string for all similiary named elements. If there is no, is anyone interested in writing one?
ByteString would be only useful for (undecoded) input. XML identifiers and text have to be Unicode, thus the 'text' library could be a replacement for String. In the pre-'text' era I tried to use ByteString as input and String for XML identifiers and text and got no significant speedup.
Second question. I'd like to have a package for read-write-edit SVG graphics. I think, xslt (both transformations and formatting object) are interesting too. Is anyone considering writing such packages?
It would be nice. We already have HPDF for PDF construction and hps for PostScript construction and cairo for construction of PDF, PS, SVG.
