Groovy XmlSlurper replaceNode無法與找到的節點一起工作

Question

我遇到問題以編程方式使用replaceNode時，一個簡單的示例工作正常。

基於以前的問題，此代碼可以工作，但換出標記爲SWAP的行並將其中斷。

任何人都可以告訴我如何使這個工作與從查找{}調用返回的節點？

package com.az.util.test 

import groovy.xml.StreamingMarkupBuilder 
import groovy.xml.XmlUtil 

def CAR_RECORDS = ''' 
    <records> 
     <car name='HSV Maloo' make='Holden' year='2006'> 
     <country>Australia</country> 
     <record type='speed'>Production Pickup Truck with speed of 271kph</record> 
     </car> 
     <car name='P50' make='Peel' year='1962'> 
     <country>Isle of Man</country> 
     <record type='size'>Smallest Street-Legal Car at 99cm wide and 59 kg in weight</record> 
     </car> 
     <car name='Royale' make='Bugatti' year='1931'> 
     <country>France</country> 
     <record type='price'>Most Valuable Car at $15 million</record> 
     </car> 
    </records> 
    ''' 

def records = new XmlSlurper().parseText(CAR_RECORDS) 

def allRecords = records.car 

assert 3 == allRecords.size() 

def firstRecord = records.car[0] 

assert 'car' == firstRecord.name() 

println 'country before: ' + firstRecord.'country'.text() 

def secondRecord = records.car[1] 

// SWAP 
//firstRecord.'country'.replaceNode {secondRecord.country} 
firstRecord.'country'.replaceNode {country("Isle of Man")} 

records = new XmlSlurper().parseText(XmlUtil.serialize(new StreamingMarkupBuilder().bind { 
    mkp.yield records 
    })) 

println 'country after: ' + records.car.country.find{ true }.text() 

println XmlUtil.serialize(new StreamingMarkupBuilder().bind { 
    mkp.yield records 
    })

使用的XmlSlurper使用Groovy，它完美的作品使用XPath：

def xmlDoc = """<parent> 
    <child> 
     <child1> 
     <subchild1>sub1</subchild1> 
     </child1> 
    </child> 
    <child> 
    <child2> 
    <subchild2>sub2</subchild2> 
    </child2> 
    </child> 
</parent>""" 


def sl = new XmlSlurper().parseText(xmlDoc) 
def childsRecords = sl.child 

childsRecords.child1.subchild1.each { println "$it" }
