Frequently Asked Questions

How are XML attributes handled?
XML attributes are converted to JSON properties, typically with an @ or _ prefix to distinguish them from element content.
Can I convert arrays?
Yes! JSON arrays convert to repeated XML elements with the same tag name. XML repeated elements become JSON arrays.
What about CDATA sections?
CDATA sections are converted to string values in JSON. When converting back, they become regular text content.
Is the conversion lossless?
Most conversions are lossless, but some XML features like processing instructions, comments, and document type declarations may not be preserved in JSON.
