如何从使用名称空间的xml文件中读取特定数据c#

本文关键字：读取 文件 数据 xml 空间 | 更新日期: 2023-09-27 18:28:57

通过这种方式，我试图读取类似CurrencyCode & MonetaryValue的值，但我在代码中遗漏了一些内容，因此我会出错。命名空间出现问题。我在这里粘贴我的代码。所以请尽可能纠正我的错误。感谢

string responseXml=@"<soapenv:Envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"">

更新

我设法做到了。

如何从使用名称空间的xml文件中读取特定数据c#

如果您只对CurrencyCode和MonetaryValue节点感兴趣，那么您可以使用XDocument查看Descendants，以确定它是否存在。

var doc = XDocument.Parse(responseXml);
// Element now has the two nodes CurrencyCode and MonetaryValue.
var elements = doc.Descendants().Where(d => d.Name.LocalName == "CurrencyCode" || d.Name.LocalName == "MonetaryValue");
