Re: Comparison evaluation in XPath

comparison evaluation
      3 > 2 > 1

  would be reduced first to

      true > 1

  which would evaluate to false. But shouldn't the answer be true?


It depends what you mean by "should". You gave an accurate description
of why it should and does return false. The fact that the 9 characters
3 > 2 > 1
parse as (3 > 2) > 1 using the more or less consistent grammar of
Xpath but as (3 > 2) and (2 > 1) using the unspecified and probably
unspecifiable grammar of conventional mathematical notation, and so
produce different results shouldn't be surprising should it?
