Reindent XML and check that it is well-formed.

About this tool
Reindents XML while preserving attributes and element order. The document is validated as it is parsed, so a malformed one is reported rather than silently reshaped.
Limitations
- Reindenting mixed content can change how whitespace is interpreted between inline elements.
Questions
- Can it fetch a DTD or schema?
- No. The parser performs no DTD processing and resolves no external entities, which is what makes XXE structurally impossible here.
