Data.XML.Types
Description
Basic types for representing XML.
The idea is to have a full set of appropriate types, which various XML libraries can share. Instead of having equivalent-but-incompatible types for every binding, parser, or client, they all share the same types can can thus interoperate easily.
This library contains complete types for most parts of an XML document, including the prologue, node tree, and doctype. Some basic combinators are included for common tasks, including traversing the node tree and filtering children.

A fully qualified name.
Prefixes are not semantically important; they are included only to
simplify pass-through parsing. When comparing names with Eq
or Ord
methods, prefixes are ignored.
The IsString
instance supports Clark notation; see

the OverloadedStrings

Doctypes
Note: due to the incredible complexity of DTDs, this type only supports external subsets. I've tried adding internal subset types, but they quickly gain more code than the rest of this module put together.
It is possible that some future version of this library might support internal subsets, but I am no longer actively working on adding them.

Incremental processing
Some XML processing tools are incremental, and work in terms of events
rather than node trees. The Event
type allows a document to be fully
specified as a sequence of events.
Event-based XML libraries include:
