Handle XML entities in JSON (no upload)
Understand how entity decoding works in DOMParser and how to validate output safely.
XML schema validation basics: attribute-preserving mapping vs element-only mapping
XML schema validation basics: when to choose attribute-preserving mapping vs element-only mapping, with a safe no-upload decision workflow.
TL;DR: Start strict on a sample, apply minimal fixes, then scale only after validation passes.
Decision matrix
| Criteria | attribute-preserving mapping | element-only mapping |
|---|---|---|
| Best when | You need strict, repeatable output | You need rapid triage on messy input |
| Risk profile | Lower hidden-issue risk, more upfront checks | Higher hidden-issue risk, faster initial pass |
| Typical speed | Slower first pass, faster downstream debugging | Faster first pass, may need rework later |
| Good for | Stable XML pipelines | One-off fixes and incoming unknown formats |
| Avoid if | Input is heavily malformed and urgent turnaround is required | You need audit-grade guarantees |
Choose attribute-preserving mapping when
- You need deterministic results for repeated XML runs.
- You are fixing production data where hidden breakage is costly.
- You want clear pass/fail criteria before conversion or export.
Choose element-only mapping when
- You are in early triage and need to narrow the problem quickly.
- You are dealing with mixed-quality inbound files from multiple sources.
- You need an iterative cleanup loop before strict validation.
Recommended no-upload workflow
- Validate a representative sample first. Confirm exact error class/position.
- Pick workflow A or B. Use strict path for quality, flexible path for triage.
- Apply the smallest safe fix. Avoid broad rewrites before validation is green.
- Re-validate and convert/export. Only then run batch processing.
