XML Attribute Extractor

Extract every XML attribute with its element path, name, value, and namespace details. Paste XML to inspect attributes and export the results as text, CSV, or JSON. Walks the parsed element tree and emits one row per attribute, including namespace declarations when requested. Everything runs in the current browser tab, so you can examine the result before copying it into a script, test fixture, migration, or data pipeline.

How to use this developer tool

  1. Paste the XML input or load a local file.
  2. Choose the options that match the source format.
  3. Select Extract Attributes or press Ctrl/Cmd + Enter.
  4. Review the summary and export the output you need.

What this developer tool does

This page walks the parsed element tree and emits one row per attribute, including namespace declarations when requested. The main output is ready to copy, while the structured exports retain the diagnostic fields used in the summary.

The parser rejects malformed XML, then visits elements in document order. Paths use sibling indexes only when repeated names would otherwise collide.

Namespace prefixes are preserved as written by the browser XML parser; namespace URIs are reported separately.

Example

Input

<catalog xmlns:x="urn:store">
  <book id="b1" x:status="new"><title lang="en">Orbit</title></book>
  <book id="b2" available="true"/>
</catalog>

Running the sample produces a tool-specific report in the output panel, with counts that correspond to the parsed records or nodes.

Use cases

  • Check incoming XML before an import or migration.
  • Create repeatable fixtures for parser and ETL tests.
  • Inspect structure without installing a command-line package.
  • Export a compact report for code review or issue tracking.

Tips for reliable output

  • Keep an untouched copy of the source before transforming it.
  • Test one representative edge case as well as the happy path.
  • Review quoted fields, Unicode, and empty values explicitly.
  • Use the JSON export when another program will consume the report.
  • Re-run the tool after changing any parsing option.

Processing details

The parser rejects malformed XML, then visits elements in document order. Paths use sibling indexes only when repeated names would otherwise collide. Processing time is measured in the browser and the original input is left unchanged.

Namespace prefixes are preserved as written by the browser XML parser; namespace URIs are reported separately.

Frequently asked questions

What input does XML Attribute Extractor accept?

Paste well-formed XML. Files are processed locally in the browser.

Does it upload my data?

No. The core processing runs in this page and does not send the pasted content to an API.

How are malformed inputs handled?

The tool stops and shows an error instead of silently returning a partial result.

Can I export the result?

Yes. Copy the main output or download it, and use CSV or JSON export when the structured report is available.

What should I verify before production use?

Namespace prefixes are preserved as written by the browser XML parser; namespace URIs are reported separately.
