Katharina,
I have taken your source and modofied it to the way I use exist.
My site map fragment reads:
<!-- test -->
<map:pipeline>
<map:match pattern="test.html">
<map:generate
src="xmldb:exist://localhost/exist/xmlrpc/db/addressbook/contacts.xml"/>
<map:transform src="simple.xslt"/>
<map:serialize type="html"/>
</map:match>
</map:pipeline>
I grab the data from exist using the XMLDB protocol in a generator. Your contact list
is stored in the addressbook
collection with name contacts.xml. Personally I would store each contact under a
different file called {id}.xml so you
can take advantage of exists search capability whilst making insters/updates/deletes
much simpler as you are dealing
with seperate files.
The XML returned from exist reads:
<?xml version="1.0" encoding="UTF-8" ?>
<contacts xmlns:exist="http://exist.sourceforge.net/NS/exist";>
<contact id="hermann">
<name>Hermann Lang</name>
<address>
<street>Himmelweg</street>
<number />
<city>Echterdingen</city>
<postalcode>70771</postalcode>
</address>
</contact>
<contact id="ilse">
<name>Ilse Honig</name>
<address>
<street>Wollkengasse</street>
<number>15</number>
<city>Wunschelbrunn</city>
<postalcode>55555</postalcode>
</address>
</contact>
</contacts>
The xslt document to show this as HTML reads:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
<xsl:template match="contacts">
<html>
<head>
<title>Contact List</title>
</head>
<body bgcolor="#FFFFFF">
<table border="1">
<tr>
<th colspan="5">Contact List</th>
</tr>
<xsl:apply-templates select="contact"/>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="contact">
<tr>
<td><xsl:value-of select="@id"/></td>
<td><xsl:value-of select="address/street"/></td>
<td><xsl:value-of select="address/number"/></td>
<td><xsl:value-of select="address/city"/></td>
<td><xsl:value-of select="address/postalcode"/></td>
</tr>
</xsl:template>
</xsl:stylesheet>
As you can see this is not complex, but you need to make sure you match on the root
node of the xml document that is
returned from exist.
To get the XMLDB protocol working within the sitemap you must make sure you have:
<!-- xmldb pseudo protocol -->
<component-instance
class="org.apache.cocoon.components.source.impl.XMLDBSourceFactory" name="xmldb">
<!-- exist driver -->
<driver class="org.exist.xmldb.DatabaseImpl" type="exist"/>
</component-instance>
... in the cocoon configuration file, under WEB-INF/cocoon.xconf in your cocoon web
application directory.
I'm sorry I can't help with the xmldb transformer, but I feel the xmldb protocol is
much more powerful, and I hope
this simple example helps you.
Paul.
