    Intersection of two nodes in umbraco with XSLT

    Hi

    I have two nodes like this:

     

    <Block>
    <nodeId>
        2009
    </nodeId>
    <nodeId>
        2010
    </nodeId
</Block>

<News>
    <nodeId>
        2009
    </nodeId>
</News>

    I would like to find whether Block and News have intersection in their children or not. For example for this sample I want to get true which means these two nodes have intersection. I really prefer to get this with one XSL (XPath) expression.

    Regards,

    Nami

    I'm going to assume that there is some sort of root elemnt around the shown xml. In that case, this should do the trick:

        <xsl:variable name="exists" select="root/Block/nodeId = root/News/nodeId" />
    <xsl:value-of select="$exists"/>

    Using the = operator will return true if there are matching nodes in the two node sets.
