How to implement if-else statement in XSLT?

Question

I am trying to implement an if -else statement in XSLT but my code just doesn\'t parse. Does anyone have any ideas?

Answer 1

The most straight-forward approach is to do a second if-test but with the condition inverted. This technique is shorter, easier on the eyes, and easier to get right than a choose-when-otherwise nested block:

     
     date:  
     
        
 mooooooooooooo 
     
     
        
 dooooooooooooo 
     

Here's a real-world example of the technique being used in the style-sheet for a government website: http://w1.weather.gov/xml/current_obs/latest_ob.xsl
