Hi folks,
I am getting data from XIndice and piping it through Cocoon. I'm getting an
exception I don't understand when I do something particular in XSLT.
I have a bunch of book reviews in my XML database and am listing the book
authors. I'm using the "not preceding" trick to remove duplicate authors.
This works.
I'm now trying to list the number of reviews we have for each of those
unique authors.
I'm doing this with two variables - one is the current author fullname, and
the other is supposed to be the count of reviews with that author. So I'm
doing this
<xsl:variable name="thisauthor">
<xsl:value-of select="fullname"/>
</xsl:variable>
<xsl:variable name="numarticles">
<xsl:value-of select="count(//author[fullname==$thisauthor])"/>
</xsl:variable>
Now I'm pretty sure I've got this count line wrong, but should it cause the
following exception?
org.apache.cocoon.ProcessingException: Exception in creating Transform
Handler: java.lang.RuntimeException: Programmer's assertion in
getNextStepPos: unknown stepType: -1
If I comment out the count line I don't get the exception.
Any ideas for a relevant tutorial, or can anyone see what I'm doing wrong.
This is the basic structure of the xml I'm processing.
<collection:results>
<collection:result>
<review>
<author>
<fullname>
etc etc
I'm using a CVS build of Cocoon which is several weeks old. Tomcat
4.0.something, Java 1.3, RedHatLinux 7.2
