What is YAML → XML?
A YAML→XML converter that maps maps to nested elements, lists to repeated child elements, and scalars to text nodes with proper escaping.
How it works
The YAML parses with js-yaml, then a small serializer walks the tree, singularizing list item names and escaping all text and attribute values.

Examples
Data interchange
Convert a YAML data file to XML for legacy systems and SOAP services — nested maps become elements, lists become repeated elements.
Common mistakes
XML doesn't accept every YAML shape
Non-string keys and mixed-type lists need naming rules. The converter applies deterministic naming and flags what needs review.
Frequently asked questions
How are root documents handled?
The top-level map becomes the document root element with child elements per key.
Is the output valid XML?
Yes — all values are escaped, and the result parses as well-formed XML.
