When I try to use the code below I get a duplicate variable error

  • 0

When I try to use the code below I get a duplicate variable error because variables are immutable. How do I set the smaller of the two variables ($nextSubPartPos and $nextQuestionStemPos) as my new variable ($nextQuestionPos)?

        <xsl:variable name='nextQuestionPos'/>         <xsl:choose>             <xsl:when test='$nextSubPartPos &lt; $nextQuestionStemPos'>                 <xsl:variable name='nextQuestionPos' select='$nextSubPartPos'/>             </xsl:when>             <xsl:otherwise>                 <xsl:variable name='nextQuestionPos' select='$nextSubPartPos'/>             </xsl:otherwise>         </xsl:choose>

  1. Don’t close the xsl:variable node in the first line. That is, take the / out of it, then put an </xsl:variable> after </xsl:choose>. Next, change the <xsl:variable> nodes inside the choose to <xsl:value-of> nodes.

    That is, you want to set the value of the variable with the choose. There are two ways to set the value of a variable. One is the select attribute, the other is the inner text of the node.

    <xsl:variable name='nextQuestionPos'>     <xsl:choose>          <xsl:when test='$nextSubPartPos &lt; $nextQuestionStemPos'>                <xsl:value-of select='$nextSubPartPos'/>          </xsl:when>          <xsl:otherwise>                <xsl:value-of select='$nextSubPartPos'/>          </xsl:otherwise>     </xsl:choose> </xsl:variable>
