Groovy：为xml标记添加名称空间

Question

我需要为xml标签添加名称空间，这是使用StreamMarkupBuilder.bind开发的，下面给出了更多详细信息。

我的XML关注，

String xml =`<CarXml> 
                 <Cars>
                    <Car>
                      <CarDetails>
                           <Model>Chevrolet Colorado</Model>
                           <Transmission code='A'>Automatic</Transmission>
                           <AirCondType code='R'>Yes</AirCondType>
                           <Passengers>4</Passengers>
                           <Doors>2</Doors>
                           <Luggage>
                               <Large>12</Large>
                           </Luggage>
                       </CarDetails>
                     </Car>
                 </Cars>
              </CarXml>`
 def parsed = new XmlSlurper(false, false).parseText( xml )

String request = new StreamingMarkupBuilder().bind {
       CarRequest(xmlns="http://maven.apache.org/POM/4.0.0")
       {
            CarRateRulesRequestDetails()
            {
                  mkp.yield parsed.Cars.Car.children()

            }
       }
}

这样做后我得到了这个

<CarRequest xmlns="http://maven.apache.org/POM/4.0.0">
      <CarRateRulesRequestDetails>
           <CarDetails>
                <Model>Chevrolet Colorado</Model>
                <Transmission code='A'>Automatic</Transmission>
                <AirCondType code='R'>Yes</AirCondType>
                <Passengers>4</Passengers>
                <Doors>2</Doors>
                <Luggage>
                    <Large>12</Large>
                </Luggage>
           </CarDetails>
      </CarRateRulesRequestDetails>
</CarRequest>

但我想要的是

 <CarRequest xmlns="http://maven.apache.org/POM/4.0.0">
      <CarRateRulesRequestDetails>
           <CarDetails xmlns="http://maven.apache.org/POM/4.0.0">
                <Model xmlns="http://maven.apache.org/POM/4.0.0">Chevrolet Colorado</Model>
                <Transmission code='A'>Automatic</Transmission>
                <AirCondType code='R'>Yes</AirCondType>
                <Passengers>4</Passengers>
                <Doors>2</Doors>
                <Luggage>
                    <Large>12</Large>
                </Luggage>
            </CarDetails>
      </CarRateRulesRequestDetails>
 </CarRequest>

如何在这种情况下添加命名空间..？ 任何帮助都很受欢迎..
