Question

I’m a newbie in XSLT & XPath so please forgive me for this simple question.

I have the following XML file:

<?xml version="1.0"?>
    <Configuration serviceName="Just Service" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration">
      <Page name="Books">
        <Instances count="5" />
        <ConfigurationSettings>
          <Setting name="index" value="true" />
          <Setting name="number" value="value1" />
          <Setting name="bookstorage" value="value2"/>
        </ConfigurationSettings>
      </Page>
      <Page name="Magazines">
        <Instances count="7" />
        <ConfigurationSettings>
          <Setting name="index" value="false" />
          <Setting name="number" value="value1" />
          <Setting name="magazinestorage" value="value3"/>
        </ConfigurationSettings>
      </Page>
    </Configuration>

All I want is to change the following values …

value1 – for number (in two places);
value2 – for bookstorage;
value3 – for magazinestorage;

… and to remain all the other content unchanged.

For this, I want to use msxsl.exe (Microsoft command line utility). Could you please give me a hint with XSLT style sheet example? How to process initial XML file with XSLT in the most effective way?

Thanks,
Rac

Here is a sample XSLT 1.0 stylesheet that takes three parameters with the new values:

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:sc="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration"
  exclude-result-prefixes="sc"
  version="1.0">

  <xsl:param name="p1" select="'foo'"/>
  <xsl:param name="p2" select="'bar'"/>
  <xsl:param name="p3" select="'foobar'"/>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="sc:Setting[@name = 'number']/@value">
    <xsl:attribute name="{name()}">
      <xsl:value-of select="$p1"/>
    </xsl:attribute>
  </xsl:template>

  <xsl:template match="sc:Setting[@name = 'bookstorage']/@value">
    <xsl:attribute name="{name()}">
      <xsl:value-of select="$p2"/>
    </xsl:attribute>
  </xsl:template>

  <xsl:template match="sc:Setting[@name = 'magazinestorage']/@value">
    <xsl:attribute name="{name()}">
      <xsl:value-of select="$p3"/>
    </xsl:attribute>
  </xsl:template>

</xsl:stylesheet>
