Hi Ranchers,

I have some XML data of the following structure.

Now I need to process this data using XSL and ensure that the duplicate elements are output only once. Also the order of the elements should not be changed. The output for the above should look like.

Try as I hard I can, I am not able to make any headway. Will really appreciate any leads.

Try this:

<xsl:template match="@*|node()">
<xsl:if test="not(node()) or not(preceding-sibling::node()[.=string(current()) and name()=name(current()])">
<xsl:apply-templates select="@*|node()"/>
