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.

If you mean, "how do you select all <post> elements that contain a
child <tag> element with the value 'example' " then then its:

select="post[tags/tag = 'example']"
