XML Formatter & XPath Tester

XML

Result

Formatted XML

XPath query

For a default namespace (like sitemaps), use the prefix d:. Other prefixes come from the document.

#Match

As JSON

XML converted to JSON

01

What it does

Checks XML is well-formed, pretty-prints or minifies it, runs XPath 1.0 queries with namespaces and converts it to JSON.

  • Well-formedness errors with line numbers
  • Pretty-print or minify
  • XPath 1.0 with namespaces (default namespace as d:)
  • Matches listed with their paths

02

Private by design

Everything happens in your browser. Nothing you type, paste or upload is sent anywhere, and it keeps working offline once the page has loaded.

03

What you get

Formatted XML, query results and JSON, with a Copy and a Download button on every result.

  • XPath
  • Sitemaps
  • RSS

Why it matters

XML is still everywhere on the web: sitemaps, RSS and Atom feeds, SVG, SOAP APIs and office files. A single unclosed tag breaks the whole file, and minified feeds are impossible to read.

This tool checks the XML with the browser's own parser and points to the line with the problem, formats it neatly, and runs XPath queries, which is the quickest way to pull every <loc> out of a sitemap or every title out of a feed. Namespaces work too.

By the numbers

Elements in the sample sitemap<urlset>: 1; <url>: 3; <loc>: 4; <lastmod>: 3; <priority>: 3; <image>: 1<urlset>1<url>3<loc>4<lastmod>3<priority>3<image>1
Counted with Python's XML parser from this tool's 593-byte sample. The sitemap uses a default namespace, which is why the XPath examples write //d:url/d:loc; a plain //url finds nothing. Source: XPath 1.0.

How to use it

  1. Paste the XML.
  2. Fix any error at the line shown.
  3. Type an XPath query to pull out values.
  4. Copy the formatted XML, the matches or the JSON.

FAQ

Does it validate against a schema (XSD)?

No. It checks the XML is well-formed. Schema validation needs the XSD, and usually a server-side tool.

How do I query a namespaced document?

Elements in the default namespace use the d: prefix, for example //d:url/d:loc in a sitemap. Other prefixes work as declared.

Which XPath version?

XPath 1.0, which browsers support natively.

How are attributes shown in JSON?

With an @ prefix, and text content as #text when an element also has attributes or children.
