JARV Ant Task

JARV comes with an Ant task implementation that makes it easy to use Ant to automate validation. This document describes how you can use it.

Simple example

<project .... >
  ...
  
  <taskdef name="validate" classname="org.iso_relax.ant.JARVTask">
    <classpath path="isorelax.jar"/>
    <classpath path="msv.jar"/>
  </taskdef>
  
  <target ... >
    ...
    <validate
      schemaLanguage="http://relaxn.org/ns/structure/1.0"
      schema="myschema.rng"
      file="mydocument.xml />
    ...
    <validate
      schemaLanguage="http://relaxn.org/ns/structure/1.0"
      schema="myschema.rng">
      
      <fileset dir="xml" includes="*.xmldoc"/>
    </validate>
  </target>
</project>

First, you need to declare org.iso_relax.ant.JARVTask as a task by using a taskdef task. You should also specify the jar file of the validator implementation you'll be using. In this example, MSV is specified.

To validate documents with a schema, you need to specify three parameters. A schema language (by the schemaLanguage attribute), a schema file (by the schema attribute), and XML files to be validated.

A schema language is specified by passing its name, which is usually its namespace URI. Refer to this list for the names of major schema languages.

XML files can be specified either by a file attribute or by nested fileset elements. The latter allows multiple files to be specified easily. See the documentation of Ant for details of the syntax of fileset.

Synoposis

The JARV task supports the following parameter attributes.

Following nested element parameter is supported.

fileset

Specifies the set of files that will be validated against the schema. Multiple fileset elements can be specified. For the syntax, see the ant documentation.

By specifying neither a file attribute or nested file sets, you can check the correctness of the specified schema file.
