Hey,

I'm building an RSS Feed (well fixing it actually) and it has to work across different child doc types. The Child doc types all ahev the correct properties.

So what mi trying to do is:

  <xsl:variable name="DataSource">
    <xsl:choose>
        <xsl:when test="$currentPage [@nodeTypeAlias = 'K-KnowledgeArticle']">
            <xsl:value-of select="$currentPage//node [@alias = 'K-KnowledgeArticle']"/>
        </xsl:when>
        <xsl:when text="...">
          etc
        <xsl:otherwise>
        </xsl:otherwise>
    </xsl:choose>
  </xsl:variable>

Then:

<xsl:for-each select="$DataSource">
      <xsl:sort select="@createDate" data-type="text" order="descending" />
      <xsl:if test="position() = 1">

......

Is that possible?

Thanks.

Sorry - should have added the error message on save:

Error occured

System.Xml.Xsl.XslTransformException:
To use a result tree fragment in a path expression, first convert it to
a node-set using the msxsl:node-set() function.

Hows about using (it may be msxml:node-set, i can never remember). If the below doesn't work post the copy-of output of your variable se I can see the structure
```
<xsl:for-each select="msxsl:node-set($DataSource)">
```
