Jing task for Ant

Ant is a Java based build tool, which is becoming the build tool of choice for Java-based projects. Ant project files are written in XML.

Ant can be extended with new tasks. The Jing task for Ant allows you to efficiently validate multiple files against multiple RELAX NG patterns and integrate RELAX NG validation with other XML processing.

This version of the Jing task has bee tested with version 1.7.1 of Ant.

To use the Jing task, you must include a taskdef in your project file.

<taskdef name="jing" classname="com.thaiopensource.relaxng.util.JingTask"/>

The jing task has a required rngfile attribute which specifies the file containing the RELAX NG pattern. The files to be validated can be specified in two ways: the jing element may have a file attribute specifying a single file to be validated; alternatively, the jing element may have one or more fileset child elements specifying sets of files to be validated. For example:

<project name="example" default="validate" basedir=".">

  <taskdef name="jing" classname="com.thaiopensource.relaxng.util.JingTask"/>

  <target name="validate">
    <jing rngfile="xslt.rng">
      <fileset dir="xsl" includes="**/*.xsl"/>
    </jing>
  </target>

</project>

The jing task also has two optional boolean attributes:

compactsyntax

if true, uses the compact syntax for the schema; default is false

checkid

if true, checks for ID/IDREF/IDREFS compatibility; default is true

When invoking Ant, you must ensure that jing.jar is in your class path.
