Making XML Readable Again
Where XML still runs things
JSON won the API wars, but XML never left the building:
| Domain | XML's role |
|---|---|
| Banking / enterprise integrations | SOAP services with strict schemas |
| RSS and podcast feeds | The entire format is XML |
| Sitemaps | sitemap.xml is how search engines crawl you |
| Android development | Layouts, manifests, resources |
| Office documents | DOCX/XLSX are zipped XML |
| E-invoicing standards | Most national formats are XML schemas |
The errors that break parsing
XML is strict by design. The recurring offenders: an unclosed tag (every opener needs its closer), a bare & in text (must be & — URLs with query strings inside XML trip this constantly), mismatched nesting (close inner elements before outer), and multiple root elements (exactly one allowed). The formatter's validation points at the line; the indentation it adds makes mismatched nesting visible to the naked eye, which single-line machine output never is.
Formatting as the first debugging step
A SOAP response or feed arrives as one endless line; formatted, its structure — and the field you're hunting — appears. The same instinct applies across formats: JSON gets the JSON formatter, web markup the HTML formatter. If you're here because of sitemap errors in Search Console, generate a clean one with the sitemap generator instead of hand-editing.
