One additional step is not mentioned in Joerg's description. You must get
cocoon to build its xpatch task code before you can run it over this and
that. A sample from the heml build.xml file is:
<!-- XPatch Stuff -->
<target name="xpatch" depends="xpatch_gump,xpatch_jars"/>
<target name="xpatch_init">
<ant antfile="${cocoon.home}/tools/targets/init-build.xml"
dir="${cocoon.home}" target="init-tasks"/>
<taskdef name="xpatch" classname="XConfToolTask"
classpath="${cocoon.ant.tasks}"/>
</target>
<target name="xpatch_gump" depends="xpatch_init">
<xpatch file="${cocoon.home}/gump.xml"
includes="xpatches/*.xgump"
/>
</target>
<target name="xpatch_jars" depends="xpatch_init">
<xpatch file="${cocoon.home}/lib/jars.xml"
includes="xpatches/*.xjars"
/>
</target>
If someone is interested in doing this with their own project, they would
probably find the exist_as_block code above the easiest to pick apart.
