XML Analyzer: Analyze XML Structure Online
An XML analyzer goes beyond viewing or formatting: it inspects the document's structure and reports what's actually in it: element and attribute counts, nesting depth, every namespace in use, the largest elements, and well-formedness errors. Paste any XML document and get a full structural report in your browser, with nothing uploaded.
How it works
- 1
Paste your XML document into the editor.
- 2
Click Analyze XML: the document is parsed and profiled client-side.
- 3
Review the report: structure stats, namespace map, depth, and any well-formedness problems.
Frequently asked questions
What does an XML analyzer do that a viewer doesn't?
A viewer shows you the tree; an analyzer measures it. This tool reports element/attribute/text-node counts, maximum nesting depth, all namespaces with their prefixes, document size, and structural warnings: the numbers you need to judge whether a document is sane before processing it.
Can it analyze WSDL files?
Yes. WSDL is XML, so the structural analysis works. For WSDL-specific insight (services, ports, operations, SOAP templates, health score), use the dedicated WSDL Analyzer which parses the contract semantics.
How is the XML parsed, and is it sent to a server?
Parsing uses your browser's native DOMParser, entirely client-side. The document never leaves your machine.
What are common causes of 'not well-formed' errors?
Unclosed tags, mismatched tag case (XML is case-sensitive), unescaped & or < characters in text, multiple root elements, and missing quotes around attribute values. The analyzer surfaces the parser's exact error message and line.
