If that is not the case, if the top-level element were called something else, the text contained by the assert element would delivered to the user as an indication that the rule failed. The difference is that test in an assert element contains an expression that should evaluate to true in the given context for the structure to be valid; a report element's test expression creates a validity rule that should evaluate to elements to complete the schema.This basic schema only hints at Schematron's power.Any valid XPath expression that can be evaluated as true or false can be used to test a document's structure. /usr/bin/perl -w use strict; use XML:: Schematron:: Lib XSLT; my $schema_file = $ARGV[0]; my $xml_file = $ARGV[1]; die "Usage: perl schemafile XMLfile.\n" unless defined $schema_file and defined $xml_file; my $tron = XML:: Schematron:: Lib XSLT-.The reason is that the Schematron module actually ships with several backends that can be chosen based on the type of processor that you want to use.XML:: Xerces requires the Apache Xerces C XML parsing library, available from Michael, XML:: Parser has all the workings of a validating parser, and libxml-enno includes a parser that will validate against a DTD, XML:: Parser:: Checker I think, someone will correct me if I'm wrong.
