What is XML and why use an XML viewer?

XML (eXtensible Markup Language) is a markup language for structured data used in configuration files, SOAP APIs, RSS/Atom feeds, sitemaps, SVG graphics, Microsoft Office documents (.docx, .xlsx, .pptx are XML-based), and data exchange between systems. While XML is human-readable, complex nested structures, minified code, and large documents are hard to understand as raw text. Our XML viewer formats, validates, and displays XML with syntax highlighting, tree views, and collapsible elements for easy comprehension.

Is my XML data safe and private?

Yes, absolutely. All XML parsing, validation, formatting, and viewing happens entirely in your browser using native DOMParser API - there are no server uploads, database storage, or external API calls. Your data never leaves your device. This makes our viewer perfect for configuration files with credentials, SOAP responses with sensitive data, API keys, authentication tokens, and confidential document structures.

Can the viewer validate XML syntax and show errors?

Yes! The viewer provides real-time XML syntax validation using native browser XML parsing. Invalid XML is highlighted with red error indicators, precise line and column numbers, and clear error messages describing the issue (unclosed tags, mismatched start/end elements, invalid characters, malformed attributes, namespace errors, CDATA issues). Perfect for debugging hand-edited configs or malformed API responses.

What's the maximum XML file size supported?

The viewer supports XML files up to 50MB. We use efficient parsing and virtual rendering to handle large XML documents with thousands of nested elements. Very large files (>10MB) like detailed sitemaps or comprehensive configurations may take a few seconds to parse and render depending on complexity and your device's performance.

Can I view minified or compressed XML?

Yes! The viewer automatically formats minified XML (single-line, no whitespace) with proper indentation, line breaks, and structure. Minified SOAP responses, compressed RSS feeds, and machine-generated XML are instantly beautified for human readability while preserving the exact element structure, attributes, and text content.

Does the viewer work with XML from APIs and configuration files?

Yes, perfectly! The viewer handles XML from any source: SOAP API responses, REST XML responses, RSS/Atom feeds, sitemap.xml files, web.config/app.config files, Maven pom.xml, Gradle build.xml, SVG graphics source, Android layouts, and any application-generated XML. It supports all valid XML syntax including nested elements, attributes, namespaces, CDATA, comments, and processing instructions.

Can the viewer handle XML namespaces?

Yes! The viewer properly displays XML namespaces including namespace prefixes (e.g., 'soap:', 'xsi:'), namespace declarations (xmlns attributes), default namespaces, and scoped elements. Namespace URIs are shown clearly, making it easy to understand SOAP messages, RSS feeds with extensions, and complex XML schemas with multiple namespaces.

Can I copy formatted XML to clipboard?

Yes! Copy the entire formatted XML, specific elements from tree view, or raw XML source to clipboard. Paste into code editors, APIs, configuration files, or other applications. Formatting and indentation are preserved when copying, making it easy to extract and reuse XML data, configurations, or document fragments.
