anchor tag/request object populated by tag name
Hello. I am new to Cocoon and XML/XSL so please bare with me.
cocoon 1.8.2
tomacat
Win2k
I have an XML document which is dynamically generated by XYZFind (an XML database). This XML document is describing the names of the XML documents (schemas) in the XYZFind database, such as the following XML:
<?xml version="1.0"?>
<?cocoon-process type="xslt"?>
<?xml-stylesheet href="uc.xsl" type="text/xsl"?>
<xyz:output xmlns:xyz="http://xyzfind.com/schemas/xyzql/1.0">
<xyz:schema>
<MedlineCitationSet/>
<SEASON/>
<resolution/>
<spec/>
</xyz:schema>
</xyz:output>
Using XSL, I am trying to create anchor tags which will link to another XML file to display one of the schema's contents. This seems like an obvious problem, though a day of searching has not turned up any solution.
Here is my XML doc which grabs the above and results in the exception found at the bottom.
<?xml version="1.0"?>
<?cocoon-process type="xsp"?>
<?cocoon-process type="xslt"?>
<?xml-stylesheet href="viewSchemas.xsl" type="text/xsl"?>
<xsp:page language="java"
xmlns:xsp="http://www.apache.org/1999/XSP/Core"
xmlns:util="http://www.apache.org/1999/XSP/Util"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xyz="http://xyzfind.com/schemas/xyzql/1.0">
<xsp:structure>
<xsp:include>uc.util.xyz.XYZBean</xsp:include>
</xsp:structure>
<xsp:logic>
private String getXML() {
XYZBean xyz = new XYZBean();
xyz.process();
xyz.getSchemas();
return xyz.getXMLString();
}
</xsp:logic>
<page>
<util:include-expr><util:expr>getXML()</util:expr></util:include-expr>
</page>
</xsp:page>
Where the first XML file is grabbed with the getXML().
This is my XSL file:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xyz="http://xyzfind.com/schemas/xyzql/1.0"
xmlns:xsp="http://www.apache.org/1999/XSP/Core">
<xsl:template match="page">
<html>
<head>
<title>XYZ Schema</title>
</head>
<body bgcolor="#ffffff">
Here is a list of schemas. Click on the link to view the entire schema.
<b>
<xsl:apply-templates select="xyz:output"/>

<xsl:template match="xyz:output">

<xsl:template match="*">

If I exclude ―> <a href="viewSchema.xml?document="<... and leave =<xsl:value-of select='name()'/> Then I do not get the exception.
So, in the end I am trying to have the resulting html look like <a href="viewSchema.xml?document=spec">spec</a>
Thank you for your time.
