What this developer tool does

The viewer parses XML with DOMParser, reports parser errors, recursively formats elements and attributes, and returns a clean indented XML representation.

XML parse → validation → recursive formatting → node statistics

For large XML documents, formatted output is easier to inspect, diff, and copy into an IDE or documentation file.

Example

Example input is preloaded in the editor. Running XML Viewer turns it into the target output and updates validation status, size, line count, and practical interpretation.

Tips for better output

  • Validate source data before converting or repairing it.
  • Use small samples first when testing a new integration format.
  • Review warnings about attributes, comments, entities, and nested structures.
  • Keep a backup of the original input when repairing or normalizing developer data.
