XML Parser: Parse XML Online
An XML parser reads raw markup and turns it into a structured tree of elements, attributes, and text you can actually inspect. Paste any XML to parse it in your browser, then explore the document tree level by level, read every attribute and namespace, and get precise diagnostics if parsing fails.
How it works
- 1
Paste your XML into the editor.
- 2
Click Parse XML: the document becomes an expandable tree.
- 3
Click nodes to expand/collapse; copy any subtree as formatted XML.
Frequently asked questions
What does an XML parser do?
It tokenizes the markup, enforces XML's syntax rules, and builds a tree (DOM) of elements, attributes, and text nodes. Everything downstream (validation, querying, transformation) operates on that tree, which is why a parse error stops everything.
How do I parse XML online without installing anything?
Paste it above. The parse uses your browser's built-in DOMParser (the same strict parser your applications use) and renders the resulting tree interactively. No upload, no signup.
Why does my XML parse in one tool but fail in another?
Usually because the lenient tool is an HTML parser, which forgives unclosed tags and unescaped ampersands. Real XML parsers are strict by specification. If it fails here, it will fail in production XML libraries too, so fix it here first.
