使用Groovy中的Map动态生成具有属性和子节点的XML

import groovy.xml.MarkupBuilder

def data = [
    root: [
        '@version': '1.0',
        person: [
            '@id': '1',
            name: 'John',
            age: 30
        ],
        address: [
            '@id': '2',
            city: 'New York',
            country: 'USA'
        ]
    ]
]

def writer = new StringWriter()
def xml = new MarkupBuilder(writer)

xml.root(data.root)

println writer.toString()

<root version="1.0">
  <person id="1">
    <name>John</name>
    <age>30</age>
  </person>
  <address id="2">
    <city>New York</city>
    <country>USA</country>
  </address>
</root>
