Lesson 5
XML Debugging Workflow
Validate, fix, format, and share repro cases.
When CI or a local build fails on XML, use a repeatable workflow:
- Paste the failing snippet into the formatter's validate mode
- Jump to the marked line in the Monaco editor (line/column in the status bar)
- Fix syntax—close tags, escape
&, fix attribute quotes - Re-validate until the status shows valid XML
- Format for readable diffs before committing
- Share a link (without secrets) so teammates see the same repro
For Maven/Android files, keep a known-good example nearby and diff mentally against your broken paste.
Pair with the JSON Formatter and YAML Formatter when configs mix formats in one repo.
Key takeaway
Treat XML errors like compile errors: locate line → fix → re-check → then polish layout.
