Variable value based on condition[URGENT]

Hi All,

XSL does not allow variable reassignment. I want to
assign a value to a variable based on a condition. Is
there any workaround for this. If this is possible
anyhow then it will save my 100s of lines of code,
complexity and add to performance as well.

The condition is:
if the count(preceding-sibling::Event) = 0
then value = 1
else If the count(preceding-sibling::Event) > 5
then value = 6
else value = count(preceding-sibling::Event)

If I read it through the xml file

document('names.xml')/Count/*[count(preceding-sibling::Event)
+ 1]

'names.xml' having the appropriate value at
appropriate tag, but in this case how do I handle the
greater than 5 condition?

Please help

Thanks
Deep
