Odd /Even using position

I have a requirement to display content in a Z fashion, e.g. Row 1, item 1 on left item 2 on right; Row 2 , item 3 on left , item 4 on right.

For this to work I am thinking I need to use XSLT's IF condition checking for odd/even number - what would be the syntax for this? some kind of

IF position() mod 2 = 0 or something? - not sure how to do this with XSLT

you use something like this:
```
<xsl:if test="position() mod 2 = 0">
...
```

Is there any examples that do what I want e.g

1 >>> 2

3 >>> 4

5 >>> 6

The DIVs I am forced to use are

<Div class="row>

<div class="first">1</div>

<div>2</div>
</div>

Next row etc..

I feel I am nearly there with the postition but strugliing with how best to do this.

out of my head it would be :

<div>
  <xsl:if test="position() mod 2 = 0">
    <xsl:attribute name="class">first</xsl:attribute>
  </xsl:if>
</div>

aah, sorry, I did not read your post correctly - the previous example was a generic example

Came up against this today, and here's the hack I came up with. You'd probably still need to add the odd/even classes, but this will help wrap two items within a div

   <xsl:variable name="opening">&lt;li&gt;</xsl:variable>
    <xsl:variable name="closing">&lt;/li&gt;</xsl:variable>
   
      <div>
           <xsl:for-each select="$nodeSet/descendant::node">
               
              
              <xsl:if test="position() mod 2 != 0">
                   <xsl:value-of select="$opening" disable-output-escaping="yes" />
                </xsl:if>
               
                  <xsl:value-of select="$currentItem/@nodeName" />
                
              <xsl:if test="position() mod 2 = 0">
                    <xsl:value-of select="$closing" disable-output-escaping="yes" />
                </xsl:if>
                   
          </xsl:for-each>
     </div>

Does this still work in 4.5.1 ? I keep getting errors ...

my code:

<!-- The fun starts here -->
<div id="companyValues">
<xsl:for-each select="$currentPage/* [@isDoc and string(umbracoNaviHide) != '1']">
<div class="companyValueItem">
   <xsl:if test="number(position()) mod 2 != 0">
        a
   </xsl:if>
                                                            
   <xsl:if test="number(position()) mod 2 = 0">
       b
   </xsl:if>

  <div class="companyValuesImage">
  <img>
 <xsl:attribute name="src">
   <xsl:value-of select="umbraco.library:GetMedia(./image, false() )/umbracoFile" />
 </xsl:attribute>

My error:

Nevermind, there was a different error in the xslt somewhere

The following snippet can be used to set the class to odd or even

<xsl:choose>
  <xsl:when test="position() mod 2 = 0">
    <xsl:attribute name="class">even</xsl:attribute>
  </xsl:when>
  <xsl:otherwise>
    <xsl:attribute name="class">odd</xsl:attribute>
  </xsl:otherwise>
</xsl:choose>
