RE: (ESED-813) XOR operator in XPath

If you have too boolean values X and Y, you can write (X xor Y) as (X != Y).
If you want to add the coercion to effective boolean value, you can write
boolean(X) != boolean(Y). Do we really need a new operator for something
that can be expressed so concisely already, and that would be used only
rarely?

Subject: (ESED-813) XOR operator in XPath



Hi,

 

XPath 2.0 http://www.w3.org/TR/xpath20/,
http://www.w3schools.com/xpath/xpath_operators.asp, currently does not
provide an 'exclusive or (XOR)' Boolean Operator. As a user of XPath, I
would view it as a useful addition to the specification. It was mentioned in
a working draft http://www.w3.org/TR/2001/WD-xquery-operators-20011220/ but
resolved at the time simply as "The XOR function will not be introduced at
this time."

 

Please consider this operator for future versions of W3C recommendations
http://www.w3.org/TR/xquery-operators/ associated with XPath.

 

Regards,
