Frequently Asked Questions
Does formatting change XML values or attributes?+
The formatter preserves the parsed XML structure, values, attributes, comments, and declaration while changing insignificant layout whitespace.
Can the formatter identify malformed XML?+
Yes. Invalid input produces a syntax message with the reported line and column instead of formatted output.
Are namespaces supported?+
Yes. Namespace prefixes and xmlns attributes are retained as part of the XML structure.
