Updating xml elements using ant

问题

I have an XSL file, which acts as a configuration file for my application. In fact it is an XML file, which has the elements wrapped around it. This file is called Config.xsl:

<?xml version="1.0" encoding="UTF-8"?>
 <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"           xmlns="http://www.example.org/Config">
 <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"               standalone="yes" />
 <xsl:template match="/">
 <Config>
      <Test>somevalue</Test>
      <Test1>someothervalue</Test1>
 </Config>
 </xsl:template>

I would like the change the value of element Test1 with a newvalue.

Below is my ant code, which I am using to update the values.

<?xml version="1.0" encoding="UTF-8" ?>
<project name="Scripts" default="test">
<taskdef resource="net/sf/antcontrib/antcontrib.properties" />
<taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask"/>
<target name="test">
    <xmltask source="Config.xsl" dest="Config.xsl">
        <replace path="Config/Test1/text()" withText="newvalue" />
    </xmltask>
</target>
</project>

I would appreciate if anyone can let me know how to get this work.

It seems you are confused with namespace. You must handle it before replacing anything. For more details how XML Task handle it goto https://today.java.net/pub/a/today/2006/11/01/xml-manipulation-using-xmltask.html#paths-and-namespaces. However, you may used this code to get our desired output:

input:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns="http://www.example.org/Config">
  <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" standalone="yes"/>
  <xsl:template match="/">
    <Config>
      <Test>somevalue</Test>
      <Test1>someothervalue</Test1>
    </Config>
  </xsl:template>
</xsl:stylesheet>

ANT script:

<project name="XML-VALIDATION" default="main" basedir=".">
  <taskdef name="xmltask" classname="com.oopsconsultancy.xmltask.ant.XmlTask"/>
  <target name="main">
    <xmltask source="config.xsl" dest="output.xml">
      <replace path="//:Config/:Test1/text()">xxxxxxx</replace>
    </xmltask>
  </target>
</project>

output:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.example.org/Config" version="1.0">
  <xsl:output encoding="UTF-8" indent="yes" method="xml" standalone="yes" version="1.0"/>
  <xsl:template match="/">
    <Config>
      <Test>somevalue</Test>
      <Test1>xxxxxxx</Test1>
    </Config>
  </xsl:template>
</xsl:stylesheet>
