我正在使用 Coldfusion 9 创建一个 SOAP Web 服务，以允许我们的销售合作伙伴将订单直接发布到我们的电子商务平台。入站 SOAP 消息包含如下所示的节点：

...
<LineItem xsi:type="ws1:Item">
   <LineNumber xsi:type="xsd:double">1</LineNumber>
    <PartNumber xsi:type="xsd:string">Widget-01</PartNumber>
    <Price xsi:type="xsd:double">100</Price>
    <Quantity xsi:type="xsd:double">4</Quantity>
    <SubscriberEmail xsi:type="xsd:string">nitwit@gmail.com</SubscriberEmail>
    <UnitofMeasure xsi:type="xsd:string">EA</UnitofMeasure>
</LineItem>
...

我收到带有以下 Coldfusion 代码的入站请求：

<cfset theXML = getsoaprequest() />

<cfset arrNodes = XmlSearch(theXML, "//LineItem") />

<cfset rtn = arrNodes[1].PartNumber.XmlText/>

但是第三行抛出一个错误：“元素 PARTNUMBER.XMLTEXT 在类型为coldfusion.xml.XmlNodeMap 的Java 对象中未定义，引用为''”

当我将第三行更改为：arrNodes[1].XmlChildren它不返回任何结果。这几乎就像子节点不存在，但arrNodes[1]返回一个完全填充的节点。

我错过了什么？

编辑：这是整个 SoapBody：

   <soapenv:Body>
  <ws1:createOrder soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

        </SoldToAddress>
     </Order>
  </ws1:createOrder>

编辑：这是我添加的代码（在斯科特的建议下），使它工作：

<cfset strXML = ToString(docXML) />     
    <cfset strXml = REReplace( strXml, "^[^<]*", "", "all" ) />         
    <cfset docXML = XMLParse(strXML) />
