command line inputs for xsl

rameshnarayan · August 4th, 2005, 01:37 AM

Hi,
   can anyone give me solution for the following :

I have build.xml ,trans.xsl and input.xml.

trans.xsl:

<?xml version ="1.0" encoding ="iso-8859-1" ?>

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="*">
  <xsl:copy>
  <xsl:copy-of select="@*"/>
  <xsl:apply-templates/>
  </xsl:copy>
</xsl:template>

<xsl:template match="property">
<property>
  <xsl:copy-of select="@name"/>
  <xsl:attribute name="value">
    <xsl:apply-templates select="@value"/>
  </xsl:attribute>
</property>
</xsl:template>

<xsl:template match="property[@name='module-name']/@value">
  <xsl:value-of select="document('input.xml')/subbuild/module[@name='inventor']/parameter/@module-name"/>
</xsl:template>

<xsl:template match="property[@name='module-dst']/@value">
  <xsl:value-of select="document('input.xml')/subbuild/module/parameter/@module-path"/>
</xsl:template>

<xsl:template match="property[@name='rmic-class-name']/@value">
  <xsl:value-of select="document('input.xml')/subbuild/module/parameter/@rmic-class-name"/>
</xsl:template>
<xsl:template match="property[@name='interface-class-name']/@value">
  <xsl:value-of select="document('input.xml')/subbuild/module/parameter/@interface-class-name"/>
</xsl:template>
</xsl:stylesheet>

build.xml:

<?xml version="1.0" encoding="iso-8859-1"?>
<project name="module-name" default="all" basedir=".">
  <description>
    Basic template that could be used as a build file by individual module owners.
  </description>

  <property name="module-name" value="some value comes here from input.xml"/>
  <property name="module-dst" value="some value comes here from input.xml"/>
  <property name="rmic-class-name" value="some value comes here from input.xml"/>
  <property name="interface-class-name" value="some value comes here from input.xml"/>
  <target name="clean">
    <delete>
      <fileset dir="${module-dst}" />
    </delete>
    <echo message="Removed directory ${module-dst}"/>
  </target>
  <target name="compile" description="Compiling individual modules">
   <rmic includes="${rmic-class-name}" base="${DST}" />
    <jar destfile="${CLIENTJAR}" update="true">
      <fileset dir=".">
        <include name="*_Stub.class"/>
      </fileset>
      <fileset dir=".">
        <include name="${interface-class-name}"/>
      </fileset>
    </jar>
  </target>
  <target name="all" depends="compile"/>
</project>

input.xml:

<?xml version="1.0" encoding="iso-8859-1"?>
<subbuild>
   <module name="communicator">
             <parameter module-name="communicator"/>
             <parameter module-path="com\ram\nms\${module-name}"/>
             <parameter rmic-class-name="${module-path}\server\cache.class"/>
             <parameter interface-class-name="rameshnarayan"/>
   </module>

</subbuild>

I'm running this from command line using saxon processor it is working nicely.

the problem is that i need to give more module information in the input.xml like

<?xml version="1.0" encoding="iso-8859-1"?>
<subbuild>
   <module name="communicator">
             <parameter module-name="communicator"/>
             <parameter module-path="com\ram\nms\${module-name}"/>
             <parameter rmic-class-name="${module-path}\server\cache.class"/>
             <parameter interface-class-name="rameshnarayan"/>
   </module>
   <module name="inventor">
             <parameter module-name="inventor"/>
             <parameter module-path="com\ram\nms\${module-name}"/>
             <parameter rmic-class-name="${module-path}\server\cache.class"/>
             <parameter interface-class-name="rameshnarayan"/>
   </module>

</subbuild>

My requirement is to read values of one particular module info at a time and generate the resultant.xml

I need to give the module name as parameter from the command line while running accordingly it has to process that particular module info from input.xml and produce resultant.xml.

Thanks and Regards

Firstly, I would not retrieve the "input.xml" every time, store it in a variable. Although I suspect that Mr. Kay's programming skills are such that Saxon caches requests for external documents it seems good practice not to rely on it.

Secondly add an xsl:param element which you pass the name of the module. You can then use a second variable to filter the input.xml

Code:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="moduleName" />
<xsl:variable name="input" select="document('input.xml')" />
<xsl:variable name="module" select="$input/subbuild/module[@name = $moduleName]" />

Another improvement might be to also pass the name of the secondary file:

Code:

<xsl:param name="inputDoc"/>
<xsl:variable name="input" select="document($inputDoc)" />

You can then pass in the params at the command line:

Code:

java -jar saxon8.jar source.xml style.xsl moduleName=communicator [inputDoc=input.xml]

You're almost there.

Add a global parameter to your stylesheet:

<xsl:param name="module"/>

In your templates, change the path expression to:

<xsl:value-of select="document('input.xml')/subbuild/module[@name=$module]/parameter/@module-name"/>

On the command line, add the parameter value:

java ... source.xml style.xsl module=inventor
