Example

Input

name: config
debug: true
services:
  - name: api
    port: 8080
  - name: db
    port: 5432

Output

<?xml version="1.0" encoding="UTF-8"?>
<root><name>config</name><debug>true</debug><services><name>api</name><port>8080</port></services><services><name>db</name><port>5432</port></services></root>

When this works best

It wraps everything under a single root element and cannot reproduce XML namespaces or processing instructions; lists become repeated sibling tags.

How it differs from related tools

The XML to YAML converter runs the opposite direction, preserving XML attributes under @attributes.
