XML Validator

Validating XML Syntax and Detecting Hierarchy Errors

Unlike HTML, which browsers attempt to render even when malformed, XML parsers are strictly "fatal on error." A single unclosed tag or illegal character immediately halts the entire parser, causing integrations to crash.

The OrbitInfra XML Validator tests your document against standard W3C XML rules, highlighting unclosed tags, attribute quotation errors, and encoding mismatches with precise line coordinates.

How to Use

1. Paste your XML document into the input editor.
2. The validator immediately invokes native browser DOMParser routines.
3. If valid, a green confirmation badge verifies that the document is well-formed.
4. If invalid, an error alert highlights the exact line and explains the failure.

Key Features & Capabilities

• Instant detection of unclosed tags, tag mismatches, and unquoted attributes.
• Displays exact line numbers and character offsets for syntax errors.
• Verifies root element consistency and XML declaration syntax.
• 100% client-side validation with zero server exposure.

Common Developer Workflows

• Checking Google sitemaps for syntax errors before submitting to Search Console.
• Validating electronic invoice XML structures (such as UBL 2.1 or ZATCA XMLs).
• Debugging SOAP envelope XML before initiating automated API tests.
• Ensuring configuration files for Java, Android, or .NET applications are error-free.
