and $ImageWidth != 0)">
I want to check if the incoming parameter ImageWidth is a non-zero
number.
I am wondering it the above expression would work?
Take it out of the spurious true() function, and it should, but....
(There is a function true() but it doesn't take any arguments, it simply
returns the Boolean value "true").
Is there a better way to do that checking ?
Try test="number($ImageWidth)"
If $ImageWidth is a number, it'll test as true unless its value is 0.
If $ImageWidth is a string, it'll be turned into a number by the number()
function, and test as true unless it is 0 or NaN ("not-a-number").
If $ImageWidth is a node-set, the first node in it will be converted into a
string, and test as above. Same if it's a result-tree-fragment.
If $ImageWidth is a Boolean, it'll be true if it's true, false if not.
Cheers,
Wendell
