Antw: Using Foreach with Attribute values

Hi Manuel,
This is called a grouping problem. Take a look at: http://www.jenitennison.com/xslt/grouping/index.html and
http://www.dpawson.co.uk/xsl/sect2/N4486.html

Cheers,
Agnes

>       <value2>valB</value2>

>       <value1>valC</value1>
>       <value2>valD</value2>

>       <value2>valF</value2>

>       <value2>valH</value2>
