DeltaXML Markup is for users who need to find out whether two XML documents are identical, or verify exactly what has been changed, who also desire a more robust solution than a document comparator or text 'diff'.

The program finds the differences between two XML files or Extensible Hypertext Markup Language (XHTML) Web pages, and outputs the results to an XML document. The program provides checking intelligent enough to ignore cosmetic differences, including changes in attribute order, changes to empty element end tags, and changes to namespace prefixes. The XML documents being compared must be well-formed and must contain the same root element.

DeltaXML requires a Java 1.2 runtime environment on Windows or Linux. The free version of the product is available for immediate download.
