FAQ
Frequently asked questions
How are XML attributes represented in the JSON output?
XML attributes are preserved as keys prefixed with @_ in the JSON output. For example, an element <user id="42"> becomes {"@_id": "42"} alongside any child elements. This convention lets you round-trip the data back to XML without losing attribute information.
How is mixed content (text and child elements together) handled?
Mixed-content elements (elements containing both text and child elements) expose the text portion under the key #text in the JSON output. For example, <p>Hello <b>world</b></p> becomes {"#text": "Hello "}.
What happens to XML namespaces?
XML namespaces (xmlns declarations and prefixed elements like ns:tag) are treated as regular attributes and element names. The namespace prefix is preserved literally in the JSON key. No namespace resolution or stripping is performed.
Are CDATA sections and XML comments preserved?
CDATA sections are handled by fast-xml-parser and their content is included as text in the output. XML comments are ignored. Processing instructions are not included in the JSON output.
