Freshmeat provides a search facility which returns matches in XML. Here
we write an XSL Transformation to transform the XML data into HTML.
The resulting XML looks like this:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE search-results SYSTEM "http://freshmeat.net/backend/fm-search-0.1.dtd">
<search-results>
<match>
<match_count>1</match_count>
<project_id>138</project_id>
<date_added>2000-02-01 01:26:10</date_added>
<date_updated>2001-01-30 21:41:22</date_updated>
<projectname_short>aeromail</projectname_short>
<projectname_full>AeroMail</projectname_full>
<desc_short>PHP based e-mail client</desc_short>
<desc_full>AeroMail is a Web-based email client written in
PHP. It uses an IMAP server to read and store messages in one
or more user-defined folders, and its features include HTTP
authentication for login (no cookies), folder manipulation,
support for sending and viewing attachments, inline image
display, multilanguage support, and URL highlighting.</desc_full>

<vitality_percent>0.02</vitality_percent>

</match>
...
</search-results>
To format this nicely we write an XSL stylesheet which defines the
transformation:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes" encoding="utf-8" />
<xsl:template match="/search-results">
<html><head><title>XSLT Freshmeat Demo</title></head>
<body bgcolor="#FFFFFF">
<table>
<xsl:call-template name="matches"/>
</table>
</body></html>
</xsl:template>
<xsl:template name="matches">
<xsl:for-each select="match">
<tr>
<td><xsl:value-of select="match_count"/></td>
<td><a href="{url_homepage}"><xsl:value-of
select="projectname_full"/></a></td>
<td><xsl:value-of select="desc_short"/></td>
<td><xsl:value-of select="date_updated"/></td>
<td><xsl:value-of select="license"/></td>
</tr>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
We now use PHP's xslt functions to apply the stylesheet to the XML:
<?php
$p = xslt_create();
$res = xslt_process($p,'freshmeat.xml','freshmeat.xsl');
if(!$res) echo xslt_error($p);
echo $res;
xslt_free($p);
?>
Here is the result
