The scala.xml library has some very annoying issues. Time for a clean-room replacement!
================================== Anti-XML: The Non-Violent Solution
Documentation and usage can be found at http://anti-xml.org
Anti-XML is a proposed replacement for the scala.xml package in
the Scala standard library. The standard package is outdated and
beyond fixing. We need to start over, on solid foundations and
unburdened by backward compatibility. Anti-XML aims for quality in
three major areas:
-
Usability
- Leverage powerful ideas like combinators and proper ADTs_
- Leverage the 2.8 collections library
- Provide consistent selector behavior
- Avoid these missteps:
Node <: NodeSeq <: Seq[Node],MetaData,Atom[String]
-
Reliability
- Use immutable data structures (in the API and under the hood too)
- Avoid bugs and race conditions
- Provide a proper
equals
-
Performance
- Lower memory usage (
Novell Vibe_ once had a 16 MB chunk of XML use 250 MB of heap!) - Provide efficient selectors
- Lower memory usage (
We are exploring many ideas_ for this project. It will be
interesting to see where things go!

Usage
The Maven artifact descriptor for the latest stable version of
Anti-XML is as follows: com.codecommit:anti-xml_2.9.1:0.3. We also regularly
push -SNAPSHOT releases to the Scala-Tools_ "snapshots" repository, for all
five of you who like to live dangerously. You should be able to use this
descriptor to easily add Anti-XML as a dependency to any project with a
Maven-compatible build system (Maven, Buildr, SBT, Gradle, Ivy, etc). The stable
artifacts themselves are hosted in the Scala-Tools_ "releases" repository. For
reference, here are a few copy/paste snippets you can use for some of the common
build systems.
SBT::
val antiXML = "com.codecommit" %% "anti-xml" % "0.3"
Buildr::
compile.with "com.codecommit:anti-xml_#{Scala.version}:jar:0.3"
Maven2::
<dependency>
<groupId>com.codecommit</groupId>
<artifactId>anti-xml_2.9.1</artifactId>
<version>0.3</version>
</dependency>
Supported Versions of Scala
Anti-XML is cross-built_ for the following Scala versions:
- 2.9.1
- 2.9.0-1
- 2.9.0
Support for the 2.8.x stream is being dropped in version 0.3. It is believed that 2.9.x has had sufficient time to mature and there is very little reason to continue to work with 2.8.1. However, if there is demand for a 2.8.1 (or 2.8.0) compatible release, open an issue and I will manually build a JAR for the appropriate version.

Contributing
Contributions are most welcome! Fork, hack, request pull, rinse and repeat. If
you're looking for things to work on, I would check the issue tracker_ or the
official TODO list. However, before you get started, be sure to read the
information in CONTRIBUTING.rst. It offers some basic code guidelines (don't
worry, curly braces aren't a religious issue here) and explains the legal
mumbo-jumbo involved in contributing.
