Reducing the need for xsl:if and code duplications

I have XSLT code that differs only by a single class element. However, all of the internal div content.

I attempted to separate out the starting tag as such:

 <xsl:if test="position() = 1">
        <div class="position first">

 </xsl:if>
 <xsl:if test="position() != 1">
        <div class="position">
  </xsl:if>

But ofcourse it produces invalid XSLT code. [The DIV's must be closed within their scope].

Is there another way to add the optional class keyword without have to reduplicate the internal contents?

Here's an alternative way you can do this without duplicating the use of the "position" class in your XSLT:

<div class="position{substring(' first', 1, 6 * (position() = 1))}">
    <!-- Whatever goes inside the div -->
</div>

And you can do this even more cleanly in XSLT 2.0:

<div class="position{if (position() = 1) then ' first' else ''}">
    <!-- Whatever goes inside the div -->
</div>

Try this:

<div class="position">
   <xsl:if test="position() = 1">
      <xsl:attribute name="class">position first</xsl:attribute>
   </xsl:if>    
</div>

The xsl:attribute instruction should override the literal attribute.

You can use xsl:choose. A sample template is given below

<xsl:template match="div">
    <xsl:copy>
        <xsl:apply-templates select="@*"/>
        <xsl:choose>
            <xsl:when test="position() = 1">
                <xsl:attribute name="class">position first</xsl:attribute>
            </xsl:when>
            <xsl:otherwise>
                <xsl:attribute name="class"><xsl:value-of select="concat('position', position())"/></xsl:attribute>
            </xsl:otherwise>
        </xsl:choose>
        <xsl:apply-templates/>
    </xsl:copy>
</xsl:template>
