Subject: RE: [xsl] Using position predicate in XPath string within selectSingleNode DOM method From: "Matthieu Ricaud" <matthieu.ricaud@xxxxxxx> Date: Wed, 24 Nov 2004 15:15:42 +0100 |
Thanks all for your answer and interess ! David I totally agree with " ITEM[1] selects the first ITEM ITEM[.=1] selects all ITEMs with string value numerically equal to 1." It's just that I tried Pieter's suggestion ...unsuccessfully. Emmanouil "In sarissa i implement the selectSingleNode by appending '[1]' to the xpath expression then calling selectNodes. Maybe MSXML's implementation has the same flaw ;-)" I actually append '[1]' (or generaly '[n]' n>0) to my Xpath before apply the SelectSingleNode method and this precisely this '[n]' which make my parser not matching anynode ! My Xpath expression work perfectly if I put it within a <xsl:value-of> in an XSL file applied to my XML but when I put it in SelectSingleNode () within an asp page (see my last mail) it do not work... So it's not an Xpath problem, the question is why a correct Xpath expression don't work with SelectSingleNode () ? Is it a bug, an exeption ? The MSDN spec about SelectSingleNode say : "var objXMLDOMNode = oXMLDOMNode.selectSingleNode(queryString); Where queryString is a string specifying an XPath expression." Isn't "ITEM[2]" a correct XPath expression ?! (PS : I'm sure my oXMLDOMNode as 2 ITEM childrens) This question is more about DOM method implementation, so maybe it shouldn't be posted hier ? sorry if so. But anyway if someone have a solution, I'll be gratefull to him ;) Matt -----Message d'origine----- De : Emmanouil Batsis [mailto:Emmanouil.Batsis@xxxxxxxxxxx] Envoye : mercredi 24 novembre 2004 13:04 A : xsl-list@xxxxxxxxxxxxxxxxxxxxxx Objet : Re: [xsl] Using position predicate in XPath string within selectSingleNode DOM method David Carlisle wrote: >do you wrap the expression in () before appending [1] (you need to) > >(/a/b/c)[1] > >will select at most 1 node > >/a/b/c[1] > >will select all c nodes that are the first child of a b. > > Now that you mention it...
