Gentoo.org index.xml - How's it done?

[wyvern]

After reading Daniel Robbin's experiences in setting up gentoo.org to use XML/XSL I was inspired to learn it and find out how to use it in my own web projects. It's been rewarding, but one thing is driving me nuts

How does the gentoo.org index.xml 'import' the news 'nuggets'? The news items are stored in separate .xml files, and the index.xml (which is amazingly short) looks like this:

This doc can help you : http://www.gentoo.org/proj/en/site.xml

I've already read all of those docs (and actually linked to one in my first post). None of them mention this topic.

you could use php and the include function (www.php.net/include)

I know I could use PHP. There are any number of solutions to this, including using Daniel's useful pytext script. I know there are other ways, but I'm curious as to whether XSLT can do it, and if not, how is gentoo.org doing it?

Call it academic interest if you like

XSLT, plus a few scripts.

<xsl:if test="/mainpage/@id='news'">
<br/><br/>
Older News:<br/>
<xsl:for-each select="document('/dyn/news-index.xml')/uris/uri[position()&=7][position()&20]/text()">
<xsl:variable name="newsuri" select="."/>
<a class="altlink" href="{$newsuri}"><xsl:value-of select="document(.)/news/title"/></a><br/>
</xsl:for-each>
</xsl:if>
