Groovy将XML转换为JSON数组

def xml = '''
<root>
  <item>
    <name>Apple</name>
    <price>1.99</price>
  </item>
  <item>
    <name>Orange</name>
    <price>0.99</price>
  </item>
</root>
'''

def xmlSlurper = new XmlSlurper()
def jsonBuilder = new groovy.json.JsonBuilder()

def root = xmlSlurper.parseText(xml)
def items = root.item.collect { item ->
  [name: item.name.text(), price: item.price.text()]
}

jsonBuilder {
  items(items)
}

def json = jsonBuilder.toString()

println(json)

{
  "items": [
    {
      "name": "Apple",
      "price": "1.99"
    },
    {
      "name": "Orange",
      "price": "0.99"
    }
  ]
