Compares XML element and attribute names by namespace URI and local name; prefix spelling and attribute order are ignored. Attribute values stay literal, including QName-like strings. Child order and parsed text whitespace are significant; XML parsing normalizes line endings and entity references. CDATA and adjacent text are combined; comments, processing instructions and XML declarations are ignored. Paths use one-based child positions after those rules, not XPath. DTDs are unsupported. Limits: 2 MiB UTF-8 per input, 50,000 nodes and 512 element levels. This is a positional tree comparison, not schema validation, byte equality or XML canonicalization.

- Read changed, added and removed nodes or attributes at the reported child positions.
- Use the stated namespace, text and ordering rules to interpret equal or different results. This report does not merge changes.
- Copy the completed difference report. Correct malformed or unsupported input before copying another result.
