Meaning
Rule based validation method that uses XPath expressions to check for specific patterns and business logic in XML files. schematron validation goes beyond basic structural checks to ensure that the content of a document meets complex industrial requirements. It allows for the definition of constraints that are too difficult to describe with a standard schema.
Assertion Logic
Developers use simple statements to define what must be true for a document to be considered valid. In schematron validation, these assertions can compare values across different parts of the same file. This capability ensures that a total amount on an invoice actually matches the sum of its individual line items.
By checking these relationships, the system prevents the entry of mathematically inconsistent data into the central accounting database, which reduces the need for manual corrections later.
Content Integrity
Quality control in data exchange depends on more than just the correct placement of tags. Applying schematron validation catches errors in business rules before they enter the main processing system. It prevents the propagation of faulty data that could lead to financial discrepancies.
Reporting Detail
Traditional validation often produces cryptic error messages that are hard for non technical staff to interpret. The output of schematron validation can include human readable text that explains exactly why a document failed. This transparency speeds up the correction process for business users.
