Subject: Re: [xsl] Do xsl processors contain optimizer for conditions? From: cert21 <cert21@xxxxxxx> Date: Sat, 14 Nov 2009 12:29:56 -0500 |
Thank you.
Technically it is a question about XPath expressions, if you look at the specification http://www.w3.org/TR/xpath#booleans then it clearly says for 'and' expressions:
"The right operand is not evaluated if the left operand evaluates to false."
And for 'or' expressions:
"The right operand is not evaluated if the left operand evaluates to true."
So it is not question about optimization, the language specification prescribes what to do.
