Hi,
I've done my research and read this list for around a week, but it's not
having any of it. Request parameters don't seem to be passed into the XSLT.
I stripped down my code to the following noddy example and tried it, without
success:
Sitemap.xmap:
-------------
<?xml version="1.0"?>
<map:sitemap xmlns:map="http://apache.org/cocoon/sitemap/1.0";>
<map:components>
<map:transformers>
<map:transformer name="xslt"
src="org.apache.cocoon.transformation.TraxTransformer">
<!-- THE FOLLOWING IS LINE WITH COMMENT 1 -->
<use-request-parameters>true</use-request-parameters>
</map:transformer>
</map:transformers>
</map:components>
<map:pipelines>
<map:pipeline>
<map:match pattern="output">
<map:generate src="input.xml" type="file"/>
<map:transform src="output.xsl" type="xslt">
<!-- THE FOLLOWING IS LINE WITH COMMENT 2 -->
<!-- <map:parameter
name="use-request-parameters" value="true"/> -->
<!-- THE FOLLOWING IS LINE WITH COMMENT 3 -->
<!-- <map:parameter name="sort"
value="date" /> -->
</map:transform>
<map:serialize/>
</map:match>
</map:pipeline>
</map:pipelines>
</map:sitemap>
input.xml:
----------
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="output.xsl"?> <data>
<reports>
<report>
<number>1</number>
<date>03/08/01</date>
</report>
<report>
<number>2</number>
<date>03/07/01</date>
</report>
<report>
<number>3</number>
<date>22/10/01</date>
</report>
</reports>
</data>
output.xsl:
-----------
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<!-- THE FOLLOWING IS LINE WITH COMMENT 4 --> <xsl:param name="sort"/>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1" />
<title>Report</title>
</head>
<body>
<!-- THE FOLLOWING IS LINE WITH COMMENT 5 -->
<p>Reports - sort order = <xsl:value-of select="$sort"/>.</p>
<p>
<table border="1">
<tr>
<th><a href="?sort=number">Number</a></th>
<th><a href="?sort=date">Date</a></th>
</tr>
<xsl:for-each select="data/reports/*">
<!-- THE FOLLOWING IS LINE WITH COMMENT 6 -->
<xsl:sort select="$sort"/>
<tr>
<td><xsl:value-of select="number"/></td>
<td><xsl:value-of select="date"/></td>
</tr>
</xsl:for-each>
</table>
</p>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Comments:
1. Specify use request parameters globally for transformer.
2. Specify use request parameters on a pipeline basis.
3. Create a parameter and pass it in "manually".
4. Declare parameter in XSLT.
5. Use parameter to write into HTML Body.
6. Use parameter to specify sort order.
When I make a request as such:
http://path/to/sitemap/output?sort=date
Using methods 1, 2 or 3 all result in 5 producing "" and 6 not working
(presumably the same result).
Now, I would suspect that methods 1, 2 OR 3 should all work, but the
parameter does not appear to be passed in.
The section of HTML I get back is:
<p>Reports - sort order = .</p>
But I would expect:
<p>Reports - sort order = date.</p>
If I put:
<xsl:sort select="date"/> instead of <xsl:sort select="$sort"/>
The report order is 2,1,3 as expected - hence I know it's processing the
pipeline, not sending input.xml and leaving the rendering all to IE!
Anybody got any ideas on what I've missed? This is driving me mad!
I've tried this from Jetty (shipped with Cocoon) and Tomcat 5.0.25 under
Windows 2000 SP4, everything is default, just extracted the source and did a
"build webapp" and dropped those files in suitable locations.
There wasn't a .war file created (as the documentation suggests) so I just
dumped the webapp directory as-is into the Tomcat directory. Cocoon appears
to work, apart from the request parameters. (all the samples seem to work
in both configs)
Any help is MUCH appreciated. Alternative methods that are more appropriate
are also welcomed.
Thank you for your time,
Ben
