Copy the images directory from the latest stable version of the docbook-xsl-ns package to '${basedir}/doc-src/images/db'. docbook-xsl-ns is available for download from the DocBook project at http://sourceforge.net/packages/docbook. We'll do this automatically for you once Ant has a task to transfer entire directories of files. You must implement your own "gen-docs" target by editing "build-docbook.xml" or overriding it in your own build file which imports "build-docbook.xml". Your "gen-docs" target must depend on -gen-docs-setup, do an "antcall" of "docbook-transform" for each doc.name, then call -gen-docs-complete. ${_for.automation.blurb} You must implement your own "validate-docs" target by editing "build-docbook.xml" or overriding it in your own build file which imports "build-docbook.xml". Your "validate-docs" target must do an "antcall" of "validate-doc" for each doc.name. ${_for.automation.blurb} <!--Dynamically generated Entity Values loaded by a catalog for document '${doc.name}' --> <!ENTITY doc_basename "${doc.name}"> <!ENTITY distro_baseurl "${distro.baseurl}"> Add Ivy jar file to Ant CLASSPATH. Obtain a 2.x version of an Apache Ivy jar file (perhaps at http://ant.apache.org/ivy/), and run a command like the following, changing the jar file path to wherever you have it saved. For any Bourne shell (incl. Bash): export ANT_ARGS; ANT_ARGS='-lib ${basedir}/build/ivy-2.2.0.jar -noclasspath' OR for any CMD-like Windows shell: SET ANT_ARGS=-lib "${basedir}/build/ivy-2.2.0.jar" -noclasspath Just created a local 'ivysettings.xml' file for you. Customize this as you wish and/or set Ivy properties (or any other docbook-specific local build properties) in a 'local.properties' file. 'cd' to the directory containing the XML source files, and run something like java -Xss${java.threadstacksize} -Dxml.catalog.files=${xml.catalog.files} -jar ${jar.file} -v ${dbxirng.url} file.xml... See the XML Commons docs about the Java System Properties to use for XML catalog resolution: http://xml.apache.org/commons/components/resolver/resolver-article.html#ctrlresolver Just created a local 'stylesheets/rng-catalog.xml' file for you. To speed up XML validations, you should edit this file.
