XML Parser Online: Validate and Inspect XML Documents
XML Parser Online checks whether pasted or dropped XML is well-formed and reports useful document details, including the root element, node counts, maximum depth, namespace prefixes, and any XML declaration. If parsing fails, it gives the error line and column. A JSON tree view makes the parsed structure easier to inspect and copy.
XML Parser Online is a browser-based XML parser that checks whether a document is well-formed and presents its structure in a readable report. It identifies the root element and shows counts for elements, attributes, text, comments, CDATA sections, and processing instructions. The report also includes maximum depth, namespace prefixes, and the XML declaration, while a JSON tree view provides another way to inspect the parsed content.
To use the tool, paste or drop XML into it. The parser reports whether the input is well-formed; when it finds an error, it provides the line and column. For valid input, you can review the document details and parsed tree, then copy what you need. The tool reports these structural details rather than asking you to configure conversion options.
XML uses named elements and attributes to represent structured information in a document. A JSON tree view can make that structure easier to review when you are working with code or need to understand XML you did not create. The element, attribute, text, comment, CDATA, processing-instruction, namespace, and depth details help you see what the document contains before you write code that consumes it.
XML Parser Online runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server; after the page has loaded, the tool works offline. It is free to use, making it useful for developers and DevOps engineers who want to inspect XML without sending document contents elsewhere.
Use the parser to check incoming XML, investigate an unfamiliar file, review document structure, or copy a useful excerpt. Whether you are learning XML or working with it as part of a development workflow, the well-formedness result and JSON tree give you a practical starting point for inspection.
Step 1: Paste your XML or drop the content into the tool to begin parsing.
Step 2: Check the well-formedness result; if there is an error, use its line and column to locate the issue.
Step 3: Review the root element, element and attribute counts, text and other node counts, maximum depth, namespace prefixes, and declaration.
Step 4: Inspect the parsed tree as JSON, then copy the details or excerpt you need.
Use case: Inspect an XML document you did not write and find difficult to read in its original form.
Use case: Check an XML value's structure before writing code that consumes it.
Use case: Review a large document and copy a useful excerpt for further work.
Use case: Confirm whether incoming XML is well-formed before investigating how your application handles it.
Use case: Check element, attribute, text, comment, CDATA, and processing-instruction counts when you need a quick document overview.
Use case: Review namespace prefixes and the root element while getting familiar with an unfamiliar XML file.
