In the clj-tagsoup example it has the following line:
(use 'pl.danieljanus.tagsoup)
The use function is like require, except it aliases the vars to the current
namespace. So the pl.danieljanus.tagsoup is the namespace to use.
If the README doesn't provide any clues, you can sometimes figure out the
namespace to use by looking at the src directory in the repository. In the
clj-tagsoup repository there's a file:
src/pl/danieljanus/tagsoup.clj
Which again indicates a namespace of pl.danieljanus.tagsoup. Just convert
"/" to "." and "_" to "-", then remove the file extension to produce the
namespace of the file.
Crouton is an alternative HTML parsing library (that's coincidentally
written by me) and can be found at: https://github.com/weavejester/crouton
Crouton uses a slightly different output syntax, which is compatible with
Clojure's xml zipper functions, making it more suitable for document
searches and traversal (IMO).
