Frequently Asked Questions

Why should developers format and indent raw XML documents?

Raw XML from SOAP web services, RSS feeds, SVG vector assets, and Android manifests is often delivered as a continuous, unindented string. Formatting introduces hierarchical indentation and line breaks, making it easy to inspect tags, attributes, and nested hierarchies.

How does the XML formatter handle self-closing tags and namespaces?

The formatter preserves self-closing tags (e.g., <meta charset="utf-8" />) and maintains XML namespace prefixes (e.g., xmlns:android="...") without altering attribute casing or element semantics.

What indentation spacing options are supported?

You can format your XML documents with 2 spaces or 4 spaces of indentation depending on your team's code formatting standards.

How does the tool detect syntax errors in XML?

The formatter parses the document using standard DOMParser in browser environments and validates that all opening tags have corresponding closing tags, catching malformed XML before formatting.

Is my XML content stored or logged anywhere?

No. All XML transformations execute in volatile browser memory. Private SOAP payloads and sensitive configuration files are never logged or stored.
