Subject: Re: [xsl] xpath confusion From: David Carlisle <davidc@xxxxxxxxx> Date: Thu, 3 Jul 2003 11:00:43 +0100 |
there are 4 possible answers that a compliant system could give to XPath: "Root/Keys/Client[@id="abc"]/ descendant-or-self::node()" 8, 6, 4 or 3 as there there is the Client node itself (as you used descendant-or-self rather than child) plus 7, 5, 3 or 2 child nodes. The child nodes are counted as follows: 7: Your XML preserves all white space and comments, and your stylesheet isn't discarding white space with xsl:strip-space 5: Your XML parser discards comments but white space is preserved 3: your parser keeps comments but the parser or stylesheet are discarding white space 2; your parser discards comments and teh parser or stylesheet is dicarding white space. So it seems that you are discarding white space most likely you have xsl:strip space somewhere or are using MSXML which takes a cavalier attitute to (not) preserving space in the input document. That assumption then explains your remaining queries XPath: "Root/Keys/Client[@id="abc"]/ descendant-or-self::comment()" selects 1 node you have one child node, here descendant-or-self::comment is the same as descendant::comment you don't get 1 extra node from the current Client node, as that isn't a comment. XPath: "Root/Keys/Client[@id="abc"]/ descendant-or-self::text()" selects 0 nodes. As above on the assumption you've discared the white space, there are no text node children, and the Client node is an element not text so 0 it is. I would like to select the 3 nodes <Client>, <a /> and <b />. Any help is appreciated. Root/Keys/Client[@id="abc"]/descendant-or-self::* will select Client and its element children and return 3 nodes.
