Support #2192
Updated by O'Neil Delpratt 5 months ago
Hi, Hopefully I am just overlooking something simple, but I have not been able to get Saxon to validate an instance XML against a DTD. I have broken down the problem into a simple example. We are using the Apache Catalog Resolver, which is working perfectly fine with Saxon transforms and schema-based validation of instance XMLs, but I cannot get it to work with a DTD. In my attached test case the files are as follows: doSaxonValidate: shell script to run a validation using com.saxonica.Validate CatalogManager.properties: Apache Catalog Manager Properties file for specifying catalog location catalog.xml: my bare bones catalog to locate the dtd instance.xml: my simple example instance XML file xml-resolver.jar: Apache XML resolver jar (version 1.2) dtd/simple.dtd: my simple dtd used to validate the instance XML To run the test: 1) Expand the attached tar.gz into a directory 2) Edit the doSaxonValidate script. Modify the SAXON_JAR variable to contain the location to your Saxon-EE jar and license. We put our Saxon license in a jar file, and add the jar to the classpath, your situation may vary. 3) Run: ./doSaxonValidate instance.xml -t This is the output that I get: ~~~ [pubsdm1:@pubsjsdev1:/home/pubsdm1/jrm29/saxonValidate $ doSaxonValidate instance.xml -t Parse catalog: file:/home/pubsdm1/jrm29/saxonValidate/catalog.xml Loading catalog: file:/home/pubsdm1/jrm29/saxonValidate/catalog.xml Default BASE: file:/home/pubsdm1/jrm29/saxonValidate/catalog.xml override: yes OVERRIDE: yes public: -//MYORG//DTD SIMPLE DTD//EN dtd/simple.dtd PUBLIC: -//MYORG//DTD SIMPLE DTD//EN file:/home/pubsdm1/jrm29/saxonValidate/dtd/simple.dtd Saxon-EE 9.5.1.7J from Saxonica Java version 1.6.0_27-rev Using license serial number V002327 Schema checking successful.

I tried this same validation using oXygen and Saxon-EE by configuring oXygen to use my example catalog.xml and it worked fine. I will be happy to assist in any troubleshooting and answer any questions you have. Thank you.
