从多行的 XML 中获取结果 [英] Get Resutls from XML with more than one line
问题描述
我想为每个订单获取订单行，并将它们作为表格发送到电子邮件正文中
I want get Order Lines for each Order and bring them to an EMail Body as Table like
值 1 |值 2 |值 3
Value 1 | Value 2 | Value 3
12345 ABC X1_
12345 ABC X1_
XML 代码:
<?xml version="1.0" encoding="utf-8"?><UniversalInterchange xmlns= "http://www.designworker/namespace" version="1.1">
<Header> </Header>
<Body>
<UniversalShipment xmlns="http://www.designworker/namespace" version="1.1">
<Shipment>
<DataContext>
<DataTargetCollection>
<DataTarget>
<Type>SMTPTYPE</Type>
</DataTarget>
</DataTargetCollection>
</DataContext>
<Order>
<OrderNumber>99348234234</OrderNumber>
<OrderLineCollection>
<OrderLine>
<LineNumber>1</LineNumber>
<OrderedQty>455.000</OrderedQty>
<OrderedQtyUnit>
<Code>MORE</Code>
</OrderedQtyUnit>
<Product>
<Code>999LAM01</Code>
<Description>New Design Work</Description>
</Product>
<QuantityMet>1.000</QuantityMet>
<ShortfallQuantity>0</ShortfallQuantity>
</OrderLine>
<OrderLine>
<LineNumber>2</LineNumber>
<OrderedQty>655.000</OrderedQty>
<OrderedQtyUnit>
<Code>SOME</Code>
</OrderedQtyUnit>
<Product>
<Code>999LAM02</Code>
<Description>OLD Design Work </Description>
</Product>
<QuantityMet>3.000</QuantityMet>
<ShortfallQuantity>45</ShortfallQuantity>
</OrderLine>
</OrderLineCollection>
</Order>
</Shipment>
</UniversalShipment>
</Body>
</UniversalInterchange>
我试图用这个代码解决这个问题:
I have tried to solve this with this code:
var xDoc = XDocument.Parse(xmlValue);
XNamespace nsp = ns;
try
{
var value = xDoc
.Element(nsp + "UniversalInterchange")
.Element(nsp + "Body")
.Element(nsp + "UniversalShipment")
.Element(nsp + "Order")
.Element(nsp + "OrderLine")
.Element(nsp + "LineNumber")
.Value;
return value;
但是当我的订单中有不止一行时，它就不起作用了.我怎样才能以更好的方式解决这个问题?
But when I have more than one Line in the Order it won't work. How can I solve this on a better way ?
推荐答案
看起来导航路径缺少一些 .Element() 调用.
Looks like the navigation path is missing a few .Element()-calls.
var orderLines = xDoc
.Element(nsp + "UniversalInterchange")
.Element(nsp + "Body")
.Element(nsp + "UniversalShipment")
.Element(nsp + "Shipment")
.Element(nsp + "Order")
.Element(nsp + "OrderLineCollection")
.Elements(nsp + "OrderLine");
// 1, 2
var lineNumbers = orderLines.Select(x => x.Element(nsp + "LineNumber").Value);
只要没有找到元素，.Element() 就会返回 null.如果您需要多个条目，您还应该使用 .Elements() 而不是 .Element().
Whenever an element isn't found, null is returned from .Element(). You should also use .Elements() instead of .Element() if you expect multiple entries.
