Re: [xsl] This could be simple, but not for me!

Thanks, Andrew

This is very very close to what I need. But the city name has to be there
only once for all names like:


100, Red
    City1
        Name1
        Name10
        Name100
        ...etc

    City2
        Name4
        Name40
        ...

200, Blue
    City1
        Name2
        Name20
        ...

    City2
        Name5
        ...

300, Green
    City1
        Name3
        Name30
        Name300
        Name3000
        ...

400, Yellow
    City2
        Name6
        ...

Is that possible as well?
