Schematron Validator

Schema validation is a process of checking XML documents against schemas. Schematron is a rule-based validation language for making assertions about the patterns in XML trees.

This tool allows you to validate XML documents against Schematron schemas.

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://purl.oclc.org/dsdl/schematron" queryBinding="xslt2">
  <pattern>
    <rule context="book">
      <assert test="@price > 10">The book price is too small</assert>
      <report test="@price > 1000">The book price is too big</report>
    </rule>
  </pattern>
