Using a Case statement in BI Publisher

This is really useful  and surprisingly easy   if you need to display multiple different pieces of information   on part of the document that depend on a value or values in  the XML  you can use a load of  "if"  or "if:else"  statements   but its much easier neater and more brain friendly to use a case statement like the following

where Company_ID199   is the tag in The tag in the XML that you want to make the decision based on


<?choose:?>
             <?when:Company_ID199=‘00040‘?>Test <?end when?>
             <?when:Company_ID199=‘00041‘?>Test 2<?end when?>
             <?otherwise:?> Test3<?end otherwise?> 
<?end choose?>
