XML → YAML 1.2. Repeated sibling elements collapse into a YAML sequence; attributes are preserved under @attributes.

XML to YAML Converter — Free Online Tool

Converts XML documents into YAML 1.2 using the browser's DOMParser, collapsing repeated sibling elements into YAML sequences, preserving attributes under @attributes and mixed content under #text, and surfacing parser errors with their position, useful for migrating legacy XML configuration, SOAP payloads and Maven or Android manifests into YAML-based tooling.

Frequently asked questions

Where do XML attributes go in the YAML output?

Each element's attributes are grouped under an @attributes mapping, and any text that sits alongside child elements is kept under #text. This matches the convention used by the XML/JSON converter so the two round-trip consistently.

How are repeated sibling elements represented?

Two or more siblings with the same tag collapse into a YAML sequence. A single occurrence stays a plain mapping, so a document with one <book> and one with several produce different shapes — worth checking if you feed the result to a schema.

Does it validate the XML?

It parses with the browser's DOMParser and surfaces the parser error message and position when the document is not well-formed. It does not validate against a DTD or XSD.
