Question

我们在字符串中收到这个xml，为了我的死，我似乎无法获得任何数据。我们只需要几个值，但它们全面深入。在下面的xml中，我们希望获得

ShippingService＆GT;率

标签＆gt;＆FileContents GT;内容

TrackingId

我尝试过xmldocument，xdocument，linq，似乎得到了任何信息。我们在其他代码中使用了xdocument和linq并且运行良好，因为有多个seqments要循环，它更简单但不在这个xml上。

<?xml version="1.0"?>

我一定很累，因为我觉得这很简单。谢谢你的帮助

Dim doc As XDocument = XDocument.Parse(strResponseData)
            Dim ns As XNamespace = "https://www.example.com/shipment/2015-06-01"
            Dim shipment As XElement = doc.Descendants(ns + "Shipment").First()

            Shipment.rate = shipment.Element("ShippingService").Element("Rate").Element("Amount").Value
Shipment.rate = shipment.Element(ns + "ShippingService").Element(ns + "Rate").Element(ns + "Amount").Value

我也试过这个并得到同样的错误

Dim doc = XDocument.Load("c:\files\11466778294298624.xml").Descendants(ns + "ShippingService").FirstOrDefault().Element(ns + "Rate")
        Shipment.rate = CType(doc.Element(ns + "Amount"), Decimal)

Answer 1

您的示例XML没有定义任何名称空间，但在您正在使用的代码中

Dim ns As XNamespace =＆＃34; https://www.example.com/shipment/2015-06-01＆＃34;

当您阅读XML时。

删除命名空间，它将起作用

    Dim doc As XDocument = XDocument.Parse(s)
    Dim shipment As XElement = doc.Descendants("Shipment").First()

此部分XML也不正确

<Contents>fP1R/6hZ8+/lw4W8uIglTthyg2l8mUfM4752G5NEy6hC...</contents>

结束标记应为大写C </Contents>

复杂的xml读取某些元素
