Re: [docbook-apps] Graphs in docbook?

And using a macrodef with ant, it's easy to generate n svg files.


  <!-- ================================================= -->
<!--   Macro definition to run xslt 2, n times-->

    <!-- Call up the macro as needed-->
    <echo>Generate aprilbm.svg</echo>
    <call-xslt2
        source="aprilbm.xml"
        output="aprilbm.svg"/>

    <echo>Generate maybm.svg</echo>
    <call-xslt2
        source="maybm.xml"
        output="maybm.svg"/>


    <echo>Generate junebm.svg</echo>
    <call-xslt2
        source="junebm.xml"
        output="junebm.svg"/>


    <echo>Generate julybm.svg</echo>
    <call-xslt2
        source="julybm.xml"
        output="julybm.svg"/>


  </target>


Nice solution!
