XML → YAML migration notes

Explains quoting differences after xmlToJson parity.

Developer notes

• CDATA-derived text survives as literals but may coerce quotes. • Namespace-heavy docs may widen keys — sanity-check YAML consumers. • Split monstrous configs before mobile editing.

When teams pick this route

• Infra rotations favoring indented YAML readability. • Helm previews after lifting XML inventories. • Docs teaching structural equivalence.

About these options

CSV exports: choose a delimiter (Auto follows locale — semicolon on /fr), RFC-minimal vs always-quoted fields, line endings, and whether to emit a header row. CSV imports: delimiter is auto-detected from the first line (comma, semicolon, tab, or pipe) — toggle whether row 1 holds column names. JSON output (XML, YAML, or CSV sources): indentation (including compact one-line) and optional recursive key sort. JSON → XML: toggle pretty-printing and indent width. YAML output: indent width, readable vs tighter layout, and deterministic string quoting (there is no source YAML file to “preserve”). XML comments are not represented in the intermediate JSON tree.

Worked examples

Regional service rollout

Sample input

<?xml version="1.0" encoding="UTF-8"?>
<service name="payments" tier="critical">
  <region id="eu" active="true">
    <host>srv-03.internal</host>
    <latencyMs>11</latencyMs>
  </region>
</service>

Sample output

service:
  name: payments
  tier: critical
  region:
    id: eu
    active: true
    host: srv-03.internal
    latencyMs: 11

Release artefacts list

Sample input

<?xml version="1.0" encoding="UTF-8"?>
<config env="production" region="eu-west">
  <database>
    <host>db-primary.internal</host>

XML → YAML FAQ

DOM caveats

Why quoted numbers?

YAML quotes ambiguous scalars; logical types still trace back to JSON intermediary parity.

XPath transforms?

Not supported — DOM snapshot only.

Huge files?

Desktop Chrome recommended.

CDATA handling?

Text nodes translate like other literals; verify downstream parsers.
