Subject: Re: [xsl] XPath 1.0 Question: Can two sibling nodes each select their parent node to yield two nodes? From: Wendell Piez <wapiez@xxxxxxxxxxxxxxxx> Date: Wed, 22 Sep 2010 18:51:22 -0400 |

This is an XPath 1.0 question.
Consider this document:
<?xml version="1.0" encoding="UTF-8"?> <books> <category> <genre>Autobiography</genre> <book> <name>My Life and Times</name> <author>Paul McCartney</author> </book> <book> <name>The Beatles</name> <author>Paul McCartney</author> </book> </category> <category> <genre>Music</genre> <book> <name>Eight Days a Week</name> <author>Paul McCartney</author> </book> </category> </books>
I would like to select the value of<genre> of each<book> with<author> equal to 'Paul McCartney'. Thus, I want the XPath to yield:
Autobiography Autobiography Music
xpath1 either returns a single value (a string, boolean or number) or a node set.
There is only one genre node with value Autobiography, so any xpath returning a set of nodes selected from the document can only return at most one node with value Autobiography.
Cheers, Wendell
