I am trying to follow along with this article on Schematron and Perl. <a href="http://www.xml.com/pub/a/2002/01/23/perl-schematron.html?page=2" rel="nofollow">http://www.xml.com/pub/a/2002/01/23/perl-schematron.html?page=2</a> My goal is to use Schematron, along with RelaxNG, to validate Docbook 5 documents. However, I can't seem to get this basic example to work. Here's my Perl script, copied from the O'Reilly article: <pre><code>#!/usr/bin/perl -w use strict; use XML::Schematron::LibXSLT; my $schema_file = $ARGV[0]; my $xml_file = $ARGV[1]; die "Usage: perl schematron.pl schemafile XMLfile.\n" unless defined $schema_file and defined $xml_file; my $tron = XML::Schematron::LibXSLT->new(); $tron->schema($schema_file); my $ret = $tron->verify($xml_file); print $ret . "\n"; </code></pre> I call the script like this: perl schematron.pl path-to-docbook.sch path-to-xml-file I get back errors having to do with the namespace "db": <pre><code>xsltCompileStepPattern : no namespace bound to prefix db compilation error: file unknown-101d82900 element template xsltCompilePattern : failed to compile 'db:sidebar' error ... </code></pre> My docbook.sch file begins as follows. It is the docbook.sch schema file that comes with the Docbook 5 distribution: <pre><code><?xml version="1.0" encoding="utf-8"?> <s:schema xmlns:s="http://www.ascc.net/xml/schematron" xmlns:db="http://docbook.org/ns/docbook"> <s:ns prefix="db" uri="http://docbook.org/ns/docbook"/> <s:pattern name="Element exclusion"> <s:rule context="db:sidebar"> </code></pre> Could it be that the Perl module uses a version of Schematron that doesn't understand namespaces? Or could it be that docbook.sch is incorrect? That would be strange, since it comes with the Docbook distribution. I may be missing something fundamental, because I'm new to Schematron.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
