Hello,
How best is the following text extracted
from the following xml, possibly using keys
or some other xslt constructs?
====
size: small, medium, large
crust: thin, pan
topping: olives, pepperoni, peppers
====
<db>
<large category="size">
<thin category="crust">
<olives category="topping/>
<pepperoni category="topping/>
</thin>
<pan category="crust">
<pepperoni category="topping/>
</pan>
</large>
<medium category="size">
<pan category="crust">
<pepperoni category="topping/>
<olives category="topping/>
<peppers category="topping/>
</pan>
</medium>
<small category="size">
<thin category="crust">
<olives category="topping/>
<pepperoni category="topping/>
<peepers category="topping/>
</thin>
<pan category="crust">
<pepperoni category="topping/>
<olives category="topping/>
<peepers category="topping/>
</pan>
</small>
</db>
The basic approach involves:
- using keys to get a unique list of possible values for the @category
attribute
- iterating over these values
- printing each followed by a colon
- getting a unique list of all xml element names which contain this
particular attribute value
- iterating over these values
printing each
printing an endline
Many thanks and Best regards,
Saverio
