I love except.

This corresponds the XPath 1.0 rule for coercing node sets to +AD4-Booleans, wherein (only) empty node sets become false(). +AD4- +AD4-Gerrit's suggestion using grouping (which I prefer) restricts the test +AD4-to duplicates among the 'a' element children of the parent being +AD4-matched. +AD4- +AD4-For this, one could also say +AD4- +AD4-a+AFsAQA-href +AD0- (../a except .)/+AEA-href+AF0- +AD4- +AD4-... but we all know no one likes 'except' (except me) ... so the +AD4-grouping solution is less apt to mystify. +AD4- +AD4-If one didn't want to see the first instance, only its duplicate(s), then +AD4- +AD4-a+AFsAQA-href +AD0- preceding-sibling::a/+AEA-href+AF0- +AD4- +AD4-Cheers, Wendell +AD4- +AD4- +AD4-On Fri, Jan 31, 2014 at 2:22 AM, Ihe Onwuka +ADw-ihe.onwuka+AEA-gmail.com+AD4- wrote: +AD4APg- No +AFs-2+AF0- means that a 2nd one exists which would be true if a 3rd one +AD4APg-existed etc. +AD4APg- +AD4APg- The full dataset picks up instances where there is more than one +AD4APg- duplicate so I can verify the above interpretation. +AD4APg- +AD4APg- Having said that your offering although more verbose is superior +AD4APg- semantically as really the best way to write this is something like +AD4APg- (and I am pleading the fifth on the syntax here) +AD4APg- exists(key('person',+AEA-href)+AFs-2+AF0-) but then you look at that and you +AD4APg- realise or can argue (I think) that what I wrote is an abbreviated +AD4APg- form of that anyway. +AD4APg- +AD4APg- I suppose a guru could tell whether they are semantically identical +AD4APg- and whether the one abbreviates the other. +AD4APg- +AD4APg- On Fri, Jan 31, 2014 at 12:45 AM, Graydon +ADw-graydon+AEA-marost.ca+AD4- wrote: +AD4APgA+- On Thu, Jan 30, 2014 at 04:38:49PM -0800, Dimitre Novatchev scripsit: +AD4APgA+AD4- +ADw-xsl:key name+AD0AIg-person+ACI- match+AD0AIg-a+ACI- use+AD0AIgBA-href+ACI-/+AD4- +AD4APgA+AD4- +ADw-xsl:template match+AD0AIg-person+ACIAPg- +AD4APgA+AD4- +ADw-duplicate+AD4- +AD4APgA+AD4- +ADw-xsl:copy-of select+AD0AIg-a+AFs-key('person',+AEA-href)+AFs-2+AF0AXQAi-/+AD4- +AD4APgA+AD4- +ADw-/duplicate+AD4- +AD4APgA+AD4- +ADw-/xsl:template+AD4- +AD4APgA+AD4- +ADw-/xsl:stylesheet+AD4- +AD4APgA+- +AD4APgA+- Can I note that the +AFs-2+AF0- would appear to suppose that there's only ever +AD4APgA+- one duplicate? +AD4APgA+- +AD4APgA+- not(position() eq 1) is likely safer. +AD4APgA+- +AD4APgA+- -- Graydon +AD4APgA+- +AD4APgA+- --+AH4------------------------------------------------------------------- +AD4APgA+- XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list +AD4APgA+- To unsubscribe, go to: http://lists.mulberrytech.com/xsl-list/ +AD4APgA+- or e-mail: +ADw-mailto:xsl-list-unsubscribe+AEA-lists.mulberrytech.com+AD4- +AD4APgA+- --+AH4--- +AD4APgA+- +AD4APg- +AD4APg- --+AH4------------------------------------------------------------------- +AD4APg- XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list +AD4APg- To unsubscribe, go to: http://lists.mulberrytech.com/xsl-list/ +AD4APg- or e-mail: +ADw-mailto:xsl-list-unsubscribe+AEA-lists.mulberrytech.com+AD4- +AD4APg- --+AH4--- +AD4APg- +AD4- +AD4- +AD4- +AD4--- +AD4-Wendell Piez +AHw- http://www.wendellpiez.com +AD4-XML +AHw- XSLT +AHw- electronic publishing +AD4-Eat Your Vegetables +AD4AXwBfAF8AXwBf-oo+AF8AXwBfAF8AXwBfAF8AXwBf-o+AF8-o+AF8AXwBf-ooooo+AF8AXwBf AF8-ooooooo+AF8AXg- +AD4- +AD4---+AH4------------------------------------------------------------------ - +AD4-XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list +AD4-To unsubscribe, go to: http://lists.mulberrytech.com/xsl-list/ +AD4-or e-mail: +ADw-mailto:xsl-list-unsubscribe+AEA-lists.mulberrytech.com+AD4- +AD4---+AH4--- +AD4-
