Subject: [xsl] Select Parent when child exists From: "Tim Gaunt" <info@xxxxxxxxxxxxxxxxxxx> Date: Tue, 27 Nov 2007 09:14:41 -0000 |
Hi, I'm trying to select all the parents that have a child node matching a certain value. It's basically transforming a blog RSS feed and I only want to select those posts that have a specific tag. The feed looks like this: <feed> <post> <title>Title of the post 1</title> <tags> <tag>example</tag> </tags> </post> <post> <title>Title of the post 2</title> <tags> <tag>example2</tag> </tags> </post> <post> <title>Title of the post 3</title> <tags> <tag>example</tag> <tag>example3</tag> </tags> </post> </feed> In this example I want posts 1 and 3. I've had a Google around but I've not found any definitive answer. I was thinking of an if statement but I would like to look the latest x posts and I'm not sure how I can do that using an if statement as postion() is incremental regardless of the quantifier. TIA Tim
