Question

I am having an issue selecting and displaying a substring from each of the child nodes using XSLT I have used the following code I’m sure I’m missing something really simple this just returns the first child node 4 times as there are 4 child nodes. Can anyone help?

XSLT CODE

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:msxml="urn:schemas-microsoft-com:xslt"
  xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets"
  exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">


<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:template match="/">

  <xsl:param name="testString">

    <xsl:for-each select="$currentPage/WhatWeDoItems [@isDoc]">
      <xsl:value-of select="whatWeDoItemDescription"/>
    </xsl:for-each>

  </xsl:param>
  <xsl:for-each select="$currentPage/WhatWeDoItems [@isDoc]">


      <p><xsl:value-of select="umbraco.library:TruncateString($testString,170,'...')"/></p>
    </xsl:for-each>

</xsl:template>

</xsl:stylesheet>

I think you can completely ditch the parameter and the loop.

<xsl:for-each select="$currentPage/WhatWeDoItems [@isDoc]">
    <xsl:variable name="description" select="whatWeDoItemDescription"/>
    <p><xsl:value-of select="umbraco.library:TruncateString($description,170,'...')"/></p>
</xsl:for-each>
