Subject: RE: [xsl] XPath: selecting matching nodes in two node-sets From: "Michael Kay" <mhk@xxxxxxxxx> Date: Mon, 20 Oct 2003 17:58:09 +0100 |
I think what you are looking for is the set of items $i such that every $k in //keyword/matches equals some $i/matches In XPath 2.0 that's //item[every $k in //keyword/matches satisfies some $i in ./matches satisfies $k eq $i] or more simply //item[every $k in //keyword/matches satisfies $x = ./matches] There's no universal quantifier ("every") in XPath 1.0, but you can use the equivalence: every $a in A satisfies X ==> not(some $a in A satisfies not(X)) So this becomes //item[not(//keyword/matches != ./matches)] Michael Kay > -----Original Message----- > From: owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx > [mailto:owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx] On Behalf Of > Richard Lewis > Sent: 20 October 2003 11:33 > To: XSL-List@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] XPath: selecting matching nodes in two node-sets > > > I have the following document: > > <results> > <keywords> > <matches>...</matches> > ... > </keywords> > <item> > ...various elements... > <matches>...</matches> > <matches>...</matches> > ... > </item> > <item>....</item> > ... > </results> > > (where <matches> elements contain the keywords themselves, CDATA). > > and what I need is an XPath expression which selects all the > <item>s which > have the same set of <matches /> elements as in the <keywords> node. > (Note: there may be repetition of <matches />s in <item>s but not in > <keywords>) > > I've tried: > "//item[matches = //keywords/matches]" > but this selects <item>s where not all the > '//keywords/matches' elements are > present. > > Cheers, > Richard > > XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list > XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
