scalaz.xml
Tony Morris
I recently ported the hackage xml library written by Galois[1] to the
scalaz-seven branch. It contains a few additional features as well.
This is an XML parser that includes features such as:
1) Error-correcting; will parse invalid XML and rebalance tags, etc.
2) Zipper for traversing the XML tree structure.
3) A cursor shifting function (on top of the zipper) that logs its
operations (using Writer monad) so they can be inspected after document
transformation has been done.
4) Pretty-printing for displaying a XML document structure.
5) Partial lenses for union types and regular lenses for record types to
ease the composition to perform a single operation. There are lots of
record types in the XML library and a few union types.
6) Example usages to demonstrate its capability. It would be good to add
a couple more to exploit the lenses. I will do this if I get a chance.
There are likely to be some possible improvements as I intended to
complete it within a certain time-frame, so comments are most welcome.
In particular, I'd like to resolve this issue:
https://github.com/scalaz/scalaz/blob/scalaz-seven/xml/src/main/scala/scalaz/xml/NSInfo.scala#L52
I'd also like to bring it more inline with the scalaz developer's guide.
Anyway, comments are most welcome -- this library is something that I
know I have needed in the past and I expect others have too, so it would
be nice to polish it up to the usual high scalaz standards. Let me know
what you think, cheers.
