Debugging XML API Responses
Separate transport, media type, XML syntax, namespaces, and application meaning.

The debugging problem
An XML-looking response can fail because of wrong Content-Type, incorrect encoding, malformed markup, or a query that ignores namespaces.
A practical sequence
- Capture a synthetic or redacted response with status and Content-Type.
- Validate well-formed XML before testing XPath.
- Inspect the document element and namespace declarations.
- Compare selected values against the API contract.
Synthetic example
HTTP/1.1 200 OK
Content-Type: application/xml; charset=utf-8
<order xmlns="urn:example:orders"><id>42</id></order>A failure to watch for
An XPath expression //order may return nothing for a default-namespaced order. Bind a prefix to urn:example:orders and query //o:order.
Limits and interpretation
Well-formed XML does not establish XSD validity or business correctness. DevPouch rejects DTD/entity declarations and fetches no references.
