Re: [xsl] following-sibling problem

Thanks Joe,

It seems the reason your process-level isn't returning any <li> tags
is because there isn't a level 3. What's happening is you are
outputting the <ul> before checking to see whether there is a value.


Yes, I should have made clear that I know I needed a test, but just
didn't know *how* to do it.

Alas the below doesn't quite work.  Besides needing to change the "<"
to "&lt;", my level 2 bullets aren't getting applied now.

I think what you want to do is check to see if:

<xsl:if test="@level < following-sibling::bullet[@level][1]">
	<ul>
		<xsl:apply-templates/> <-- You'll have to edit this
	</ul>
</xsl>

Here's the complete stylesheet:
