使用selectSingleNode时出现对象必需错误

Question

我需要创建一个函数，在该函数中我可以传递预定义的xml和密钥，并且该函数将返回值。假设我的键值为FLGVIEWALL，那么我的代码应该返回true或false。该代码是使用经典ASP创建的，以前似乎可以使用。它可能是xml格式或其他格式的问题，现在在selectsinglenode行..对象中返回错误。有人可以帮我为什么我得到这个..我在这里做错了什么。

    Function GetNodeValueText(strRet, key)
        ' Initializes the node value
        dim nodeValue

        ' Creates the DOM xml
        Set objRet = CreateObject("MSXML2.DOMDocument")
        objRet.loadXML strRet
        objRet.setProperty "SelectionLanguage", "XPath" 
        objRet.setProperty "SelectionNamespaces", "xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' xmlns:ns='http://myserver.com' " & _
            "xmlns:map='http://ws.apache.org/namespaces/axis2/map' xmlns:ax241='http://rpc.xml.coldfusion/xsd' " & _
            "xmlns:xs='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'"

        ' Gets the node value
        Set nodeValue = objRet.selectSingleNode("//ax241:entries[ax241:key='" & key & "']/ax241:value")

        ' Sets the return
        GetNodeValueText = nodeValue.text
    End Function
