我在处理 XMl 文件时遇到问题。我想循环（使用 VB.NET）该文件并提取 OrderID 元素的所有值。
<?xml version="1.0"?>
<ListOrdersResponse xmlns="https://xxx.xxxxxx.com/Orders/999uuu777">
<ListOrdersResult>
<NextToken>XXXXXXXXXX</NextToken>
<Orders>
<Order>
<ShipmentServiceLevelCategory>Standard</ShipmentServiceLevelCategory>
<OrderId>ooooooooo</OrderId>
</Order>
<Order>
<ShipmentServiceLevelCategory>Standard</ShipmentServiceLevelCategory>
<OrderId>ujuujujuj</OrderId>
</Order>
</Orders>
<CreatedBefore>2013-06-19T09:10:47Z</CreatedBefore>
</ListOrdersResult>
<ResponseMetadata>
<RequestId>8e34f7d9-3af7-4490-801b-cccc7777yu</RequestId>
</ResponseMetadata>
</ListOrdersResponse>
这是我正在尝试的代码，但它不会循环每个订单
Dim doc As New XmlDocument()
doc.Load(file)
Dim nodelist As XmlNodeList = doc.SelectNodes(".//Orders/Order")
For Each node As XmlElement In nodelist
console.writeline(node.SelectSingleNode("OrderID").InnerText)
Next
任何帮助将不胜感激。
尝试这个：
doc.Load(file)
nodelist = doc.GetElementsByTagName("Order")
For Each node As XmlElement In nodelist
Console.Writeline(node("OrderID").InnerText)
Next
