The file:// business was probably introduced by some clever windoze mail client trying to interpret the //b as part of a file URL. Sometimes these newfangled computer gadgets are too smart for our own good :-) Mark -----Original Message----- From: Jeni Tennison [mailto:jeni@j...] Sent: Wednesday, July 17, 2002 6:24 PM To: Garland foster Cc: Mark Feblowitz; 'Dare Obasanjo'; xml-dev@l... Subject: Re: Quick Xpath Hi Garland, > Thanks!, a question from Eric's answer: > > Is it file://b[preceding-sibling::*[1][self::a]] > or file://b[preceding-sibling::*[last()][self::a]] Well, neither, sorry - you shouldn't have "file:" at the beginning (I missed that in your last mail and compounded the error, sorry)! It's "//b[preceding-sibling::*[1][self::a]]" (or, better, "/foo/b[preceding-sibling::*[1][self::a]]"). The preceding-sibling axis is a reverse axis, which means that when you count the positions of the nodes that you get in the step where you use it, they get counted in reverse order. The closest preceding sibling (later in the document) is positioned 1st, the one furthest from the node that you're on (earlier in the document) is positioned last. > Meanwhile for XML-SPY users you should use > Is it file://b[preceding-sibling::*[position()=1][self::a]] > Because > Is it file://b[preceding-sibling::*[1][self::a]] > doesn't work. > > This is a XMLSPY bug isn't it? Yes.
