Syntax for logical OR,AND and not equal to

Question

Hi All,
In the rtf template we are in need of using logical OR,AND and not equal to .
<?choose:?><?when:(M= 0 & N=1) | (M= 1 & N=0)?>
<?end when?>
<?choose:?><?when:(M!= 0 & N=!1)?>
<?end when?>
<?otherwise:?><?end otherwise?><?end choose?>
Is the syntax used above is correct?
Thanks in Advance

Hi,
Been a while since I look at this sort of thing, but from what I can remember, here goes:
When you specify an element name in your XML you are actually specifying some XPath. This means you need to use XPath syntax in your <?when....?> clause.
I think you would need to re-write your statements as follows:
<?choose:?>
<?when:(M=0 and N=1) or (M=1 and N=0)?>
<? end when?>
<?when:not(M=0 and N=1)?>
<?end when?>
<?otherwise:?>
<?end otherwise?>
<?end choose?>
I hope this helps you.
