Hello,

my first post here, hope you don't mind...

I implemented a very basic news section on a client's website and created a landing page with a simple macro that lists all the headlines.
Now he's asking me to put different headers to separate posts from the same year.
Like this:

2011
- post1
- post2
- post3

2010
- post4
- post5

2009
...

How can I use xslt to automatically create the headers?
That's how I would get the date:

<xsl:value-of select="umbraco.library:FormatDateTime(data[@alias='Date'], 'yyyy')"/>

What I don't know is how to show it only before the first post from the same year...
I initially thought of manually create different directories on Umbraco for each year... that would be easy, but would also mean I'd need to manually update it next year, which I don't want to do.

Any ideas?
Please let me know if you wish more details

thanks,
Matteo
