RE: [xsl] Value at position()

["SHEIKH Sajjad" <Sajjad.SHEIKH@xxxxxxxxxxx>]

It works definitely means that It meets my needs..i get the values
properly..last()-2 is not the position() where I should look at..it was
just an example..value could be at any position.

I fetch values from all the location to different variables and then I
test those variables to display

Regards,

by "fine" I assume you mean that it doesn't generate an error but it is
not doing anything like this stated requirement.

look again at what you wrote:

position()=last()-2='A'


position() is a number (eg 1)
last() is a number eg 5
so
position = last()-2
is a boolean
which is false() in this case as 1 = 5 - 2 is false
so then you are comparing the string 'A' with the boolean value false()
this will cause the system to convert the string to a boolean, all
non-empty strings convert to trrue() so then you are comparing boolean(1
= 5 - 2) = boolean('A') which is
false()=true()
which is false() so the test is false on all items except the 2nd from
last. The content of the element is not even looked at in this
expression.
