的XmlSlurper命名空间不被使用

问题描述：

<TriadMessage xmlns="http://www.myco.com/02/11/2008/V1/TriadMessage.xsd" 
     xmlns:triad="http://www.myco.com/02/11/2008/V1/TriadTypes.xsd" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > 
<TriadRouteInfo> 
    <triad:RoutingCorrelationId>new value goes here</triad:RoutingCorrelationId> 
...

，我读使用Groovy 1.7：

triadDoc = new XmlSlurper().parseText(xmlMessage).declareNamespace(
    tm: "http://www.myco.com/02/11/2008/V1/TriadMessage.xsd", 
    triad: "http://www.myco.com/02/11/2008/V1/TriadTypes.xsd", 
    xsi: "http://www.w3.org/2001/XMLSchema-instance" 
    ) 
xmlBuilder = new StreamingMarkupBuilder() 
writer = xmlBuilder.bind {mkp.yield triadDoc}

我然后将值插入文档：

triadDoc.TriadRouteInfo.RoutingCorrelationId = dto.getReportRevisionId() 
...

和输出：

writer.toString()

这是我的文档的样子：

<?xml version="1.0" encoding="UTF-8"?> 
    <tm:TriadMessage xmlns:tm="http://www.myco.com/02/11/2008/V1/TriadMessage.xsd"> 
    <tm:TriadRouteInfo> 
    <triad:RoutingCorrelationId xmlns:triad="http://www.myco.com/02/11/2008/V1/TriadTypes.xsd">24670</triad:RoutingCorrelationId> 
...

注意，黑社会命名空间似乎每个元素。有很多这些线（我只在这里显示一个）。我希望NS仅在顶部声明，并通过黑社会提及：。我究竟做错了什么？

答

只是尝试这样做：

import groovy.xml.StreamingMarkupBuilder 

def xml = """ 
<TriadMessage xmlns="http://www.myco.com/02/11/2008/V1/TriadMessage.xsd" 
          xmlns:triad="http://www.myco.com/02/11/2008/V1/TriadTypes.xsd" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > 
    <TriadRouteInfo> 
    <triad:RoutingCorrelationId>new value goes here</triad:RoutingCorrelationId> 
    </TriadRouteInfo> 
</TriadMessage>""" 


def triadDoc = new XmlSlurper().parseText(xml).declareNamespace(
    tm: "http://www.myco.com/02/11/2008/V1/TriadMessage.xsd", 
    triad: "http://www.myco.com/02/11/2008/V1/TriadTypes.xsd", 
    xsi: "http://www.w3.org/2001/XMLSchema-instance") 

def xmlBuilder = new StreamingMarkupBuilder() 
writer = xmlBuilder.bind { 
    mkp.declareNamespace(tm: "http://www.myco.com/02/11/2008/V1/TriadMessage.xsd") 
    mkp.declareNamespace(triad: "http://www.myco.com/02/11/2008/V1/TriadTypes.xsd") 
    mkp.declareNamespace(xsi: "http://www.w3.org/2001/XMLSchema-instance") 
    mkp.yield triadDoc 
} 

triadDoc.TriadRouteInfo.RoutingCorrelationId = 'wheeee' 

println writer

它打印出来，这（通过我美化了一番，所以它不是都在同一行）：

<tm:TriadMessage xmlns:tm='http://www.myco.com/02/11/2008/V1/TriadMessage.xsd' 
       xmlns:triad='http://www.myco.com/02/11/2008/V1/TriadTypes.xsd' 
       xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'> 
    <tm:TriadRouteInfo> 
    <triad:RoutingCorrelationId>wheeee</triad:RoutingCorrelationId> 
    </tm:TriadRouteInfo> 
</tm:TriadMessage>

有什么好？
