oXygen XML Diff

Oxygen XML Diff is a complete solution for comparing and merging XML files. It offers both directory and file comparison, six different diff algorithms, and multiple levels of comparison. The comparison can also be performed inside ZIP-based archives (ZIP, JAR, ODF, OOXML). Oxygen XML Diff includes two specialized XML-aware comparison algorithms: XML Accurate, tuned for precise comparison, and XML Fast, tuned for speed at the expense of some accuracy.
