I have an XSLT-script which generates a sub menu recursively. The structure of the HTML generated is basically an unordered list: Code:<ul> <li>Item 1</li> <li>Item 2 <ul> <li>Item 2.1</li> <li>Item 2.2</li> </ul> </li> <li>Item 3</li> I'm doing some graphic stuff which involves rounded corners and therefore I need to insert code before the closing </li> tag in the nested unordered list. Like this: Code:<ul> <li>Item 1</li> <li>Item 2 <ul> <li>Item 2.1</li> <li>Item 2.2 <I WANT TO INSERT CODE HERE> </li> </ul> </li> <li>Item 3</li> This should only be done at a certain level in the structure Does anyone have an example of how to do this? Is it for example possible to check if the current node is the last node at the current level? If I could do that check, perhaps I could inject the code snippet before the closing tag? Thanks in advance!

You can count() the number of nodes and check your current position() against the count to see if you're at the last one, and then add your extra code. Or, you compare the last() function in xslt. cheers, doug.

Thanks Doug! I ended up with this simple test: Code:
<xsl:if test="count(../node) = position()">
<!-- INJECT CODE HERE -->
</xsl:if>
I checks how many nodes there are at the current level in the tree against the position of the current node in the loop. If they are the same, I know that I'm on the last node and I can inject the code before the closing </li> tag.

Hi,
you can use
<xsl:if test="position() = last()">
I think it may be little faster, count must counting in every loop.

Thanks Petr! Your alternative works just like my first attempt. It's always good to learn how to optimize for better performance!
