validate XML against legacy DTD

DTD-based XML Validator

Purpose

For some big files, xmllint fails or takes a long time. A validating parse with Java’s libraries does more or less the same checks.

Build and use

Build is configured to need Java 11. May be possible to tweak pom.xml to compile on Java 8.

mvn package dependency:copy-dependencies
java -jar .\target\i5validator-0.1-SNAPSHOT.jar -h

Read help, validate ;-)

Features:

• validate against DTD (referenced/defined in the file) and XSD (via xsi:schemaLocation)

• writes log file

• processes compressed streams (xz, bzip2, gz)

• can work in parallel

Parsing based on code from https://www.rgagnon.com/javadetails/java-0668.html
