XML Viewer
About Tool
Reading raw XML can be a headache, especially when dealing with deeply nested nodes and minimized files. This XML Viewer is a surgical utility designed to take dense, unformatted XML data and turn it into a clear, hierarchical tree. It helps developers, system administrators, and data analysts inspect the structure of their documents, find specific attributes, and identify syntax errors that might be breaking an application.
The tool supports a variety of inputs, allowing you to either paste raw text directly or open local files like .xml, .rss, or .svg. Once loaded, the interface provides a collapsible tree view that makes navigating massive datasets significantly more manageable. If your XML contains encoded URLs or attributes, you may want to use the URL Encoder and Decoder to verify the underlying links. For those migrating documentation content, the Markdown to HTML tool can be a useful companion for preparing complementary text assets.
Customizable Tree View and Indentation
A key feature of the viewer is the ability to adjust the "Indent spaces." Whether you prefer a tight 2-space look or a more expansive 4-space view, you can customize the formatting to match your coding standards. The viewer also includes a toggle to "Ignore whitespace-only text nodes," which cleans up the tree by hiding empty lines and formatting artifacts that don't represent actual data. This is particularly useful for XML generated by different systems with varying formatting styles.
Troubleshooting Malformed XML
If the XML you paste is malformed—perhaps due to a missing closing tag or an illegal character—the tool provides parse error handling. In cases where the XML cannot be rendered as a tree, the viewer offers a raw fallback mode so you can still inspect the text and manually fix the issues. You can use the "Expand All" and "Collapse All" buttons to quickly navigate the document once the errors are resolved.
Frequently Asked Questions
What file types can I upload?
You can upload standard XML files, as well as specialized formats like .xsd (schemas), .svg (vector graphics), and .rss or .atom feeds.
Can I edit the XML inside the viewer?
The viewer is primarily for inspection and formatting. For major edits, it is best to use a text editor and then re-paste the content to check the new structure.
Is there a size limit for the XML document?
While the tool can handle large files, extremely massive XML documents (several megabytes) may slow down your browser's rendering engine.
Does it support namespaces?
Yes, the tool correctly identifies and renders XML namespaces (xmlns) and prefixed tags within the tree structure.
