XML Viewer

Free Online XML Viewer

An XML viewer lets you open any XML document and see its structure with color-coded syntax highlighting, collapsible tree navigation, and detailed node statistics. We built six XML viewing utilities into one workspace so you can highlight, explore, count, extract, inspect, and search XML without downloading software or signing up. Paste your XML, upload a file from your computer, and get an interactive breakdown in seconds. Your data stays in your browser and never touches our servers.

Online XML Viewer with Tree Navigation and Search

Reading raw XML is difficult when documents grow beyond a few dozen lines. Nested elements, verbose namespace prefixes, and inline attributes make it hard to locate the data you need. Our XML viewer solves this by giving you multiple ways to explore the same document. Start with syntax highlighting to get a color-coded overview, switch to the interactive tree to expand and collapse sections, then use the search tool to jump directly to specific elements or values. You can also run the node counter to understand document complexity before parsing it in your application.

Syntax Highlighting with Line Numbers

The default XML Viewer tab renders your document with distinct colors for every XML construct. Tags are blue, attribute names are yellow, attribute values are green, text content is light gray, and comments are muted. Line numbers run down the left side and each line highlights on hover so you can track your position in large files. This is helpful when you are comparing two XML exports side by side or tracing a parsing error reported on a specific line.

Interactive Tree Exploration

The XML Tree View tab parses your document and renders every element as a collapsible node. Attributes appear inline with color coding, and child elements are indented under their parents. Nodes beyond depth 3 start collapsed so large documents remain manageable. Click any chevron to expand or collapse a branch. This is the fastest way to understand nesting structure in configuration files, SOAP messages, and data exports without scrolling through raw text.

Upload XML Files Directly

Working with local files is simple. Click the Upload XML button or drag and drop files directly onto the editor. We accept .xml, .xsl, .xslt, .svg, .xhtml, .rss, and .atom files. Because everything runs in your browser, there is no file size limit enforced by our servers and no risk of exposing sensitive content. Configuration files with credentials, SOAP definitions with internal endpoints, and data feeds with customer records stay entirely on your machine.

Analyze XML Structure with Node Counting and Attribute Extraction

Understanding document complexity is important before you write parsing logic or XSLT transforms. The Node Counter tab gives you a dashboard with total elements, total attributes, text nodes, comments, maximum nesting depth, line count, file size, and the root element name. These numbers help you estimate processing time, decide whether to stream or load the entire document into memory, and identify unusually deep or flat structures that may indicate generation issues.

Extracting Attributes for Auditing

The Attribute Extractor scans every element and produces a table showing the parent element name, attribute name, value, and full element path. This is useful when you need to audit IDs across a large schema, verify that currency attributes are consistent, or extract configuration values for documentation. Each row links back to the specific element so you can trace the attribute to its source.

Inspecting Namespaces and Prefixes

Namespace collisions are a common source of XML parsing errors, especially when merging documents from multiple sources. The Namespace Inspector detects every xmlns declaration and displays the prefix, URI, and the element where it was declared. Default namespaces are labeled clearly. Use this to verify that namespace prefixes in your XPath expressions or XSLT templates actually map to the correct URIs before debugging mysterious empty result sets.

Your Data Stays in Your Browser

We process everything using the built-in DOMParser API and JavaScript. Your XML never touches our servers. That means you can safely view production configs with database credentials, SOAP definitions with internal endpoints, and data feeds with customer information. No server communication, no cookies, no signup required.
