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']"
