【问题描述】：

我有肥皂信封请求，我想从元素中提取一些数据。

下面是一个字符串格式的肥皂信封请求，我想提取位于“

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://ACORD.org/Standards/Life/445" xmlns:aaa="http://Life/PolicyDetails/3" xmlns:date="http://exslt.org/dates-and-times">

        </aaa:getPolicyDetailResponse>

以下是我为解析数据而编写的代码，但出现空引用异常。

string contents = System.IO.File.ReadAllText(@"C:\Users\reg\CaReg-output1.txt");
                var document = XDocument.Parse(contents);
                string url = "http://ACORD.org/Standards/Life/2";
                var ns = XNamespace.Get(url);
                var xElements = document.Element(ns+"OLifEExtension").Value.ToString();

【参考方案1】：

尝试以下：

           string contents = System.IO.File.ReadAllText(@"C:\Users\reg\CaReg-output1.txt");
            XDocument document = XDocument.Parse(contents);
            XElement root = document.Root;
            XNamespace ns = root.GetNamespaceOfPrefix("ns");

            List<string> OLifEExtension = document.Descendants(ns + "OLifEExtension").Select(x => (string)x).ToList();
