Subject: [xsl] Re: What is $p in the definition of fn:subsequence ? From: "Dimitre Novatchev" <dnovatchev@xxxxxxxxx> Date: Fri, 4 Jul 2008 20:45:15 -0700 |
An additional question: The spec doesn't specify the desired behavior if $length is <= 0. Should the function return the empty sequence, a reversed subsequence (if $length is < 0) or should an error be raised? The same question goes for fn:substring(). -- Cheers, Dimitre Novatchev --------------------------------------- Truly great madness cannot be achieved without significant intelligence. --------------------------------------- To invent, you need a good imagination and a pile of junk ------------------------------------- Never fight an inanimate object ------------------------------------- You've achieved success in your field when you don't know whether what you're doing is work or play On Fri, Jul 4, 2008 at 8:16 PM, Dimitre Novatchev <dnovatchev@xxxxxxxxx> wrote: > The definition of the fn:subsequence in the F & O W3C Recommendation at: > > http://www.w3.org/TR/xpath-functions/#func-subsequence > > contains the following text: > > "Summary: Returns the contiguous sequence of items in the value of > $sourceSeq beginning at the position indicated by the value of > $startingLoc and continuing for the number of items indicated by the > value of $length. > > In the two-argument case, returns: > > $sourceSeq[fn:round($startingLoc) le $p] > In the three-argument case, returns: > > $sourceSeq[fn:round($startingLoc) le $p > and $p lt fn:round($startingLoc) + fn:round($length)]" > > > There is no definition of $p and this definitely seems to be a bug in > the document. > > Could somebody, please, confirm what is meant by "$p" in this text? > > -- > Cheers, > Dimitre Novatchev > --------------------------------------- > Truly great madness cannot be achieved without significant intelligence. > --------------------------------------- > To invent, you need a good imagination and a pile of junk > ------------------------------------- > Never fight an inanimate object > ------------------------------------- > You've achieved success in your field when you don't know whether what > you're doing is work or play
