GB/T 28181 Catalog XML Inspector

List DeviceID, Name, Status and item counts from a catalog response.

Protocol scope and method

The inspector extracts common XML tags with a conservative text parser. It does not validate against a schema or preserve namespaces.

Find Item blocks, then extract DeviceID, Name and Status tags.

Diagnostic scenario

Paste a small redacted Catalog response body and inspect XML well-formedness, command type, sequence number, device list count and item identifiers. Compare declared SumNum and DeviceList Num with the actual item population before importing it.

How to interpret the result

Well-formed XML can still violate the GB/T profile, omit required elements or use a namespace and encoding the receiver does not expect. Catalog responses may be paged, so one message is not necessarily the complete inventory.

Input reference

Catalog XML
Example default: Sample input included

Common mistakes

  • Using an unredacted production capture with vehicle, credential or network identifiers.
  • Treating one paged Catalog response as the full device inventory.
  • Treating a successfully parsed sample as standards compliance or interoperability proof.

Before using the result

  1. Confirm the protocol edition, transport framing and vendor profile before interpreting fields.
  2. Reconcile declared counts, actual Item elements and sequence numbers.
  3. Keep a redacted known-good and known-bad sample as a regression pair.

Questions to check during diagnosis

Does the GB/T 28181 Catalog XML Inspector leave my browser?

No application upload is used. Avoid putting sensitive production data in shareable URLs.

Is this a standards compliance test?

No. Confirm the edition and vendor profile with licensed documents and your target platform.

Offline diagnostic aid. Verify fields, version and vendor extensions before production use.

A syntactically valid message can still fail at transaction, dialog, profile or media layers. This guide correlates those layers without exposing credentials or real endpoints.
