遍历子列表-XMLNodeList [英] Looping through a sublist - XMLNodeList

问题描述

我遍历具有两个列表的XML文档，例如:

< xml>
< nodelist1 A>
< node1></node1>
< node2></node2>
< nodelist2 A>
< node3>
< node4>
</nodelist2>
</nodelist1>
< nodelist1 B>
< node1></node1>
< node2></node2>
< nodelist2 B>
< node3>
< node4>
</nodelist2>
</nodelist1>
</xml>

循环遍历第一个节点列表很好，但是我无法使第二个节点正常工作.

这是一个代码示例:
nodeRooms = xmlDoc.SelectNodes("/test:预订/测试:Rooms/test:Room"，ns);
foreach(nodeRooms中的XmlNode nodeRoom)
{
objWriter.WriteStartElement("Room");
objWriter.WriteStartElement("RoomTypeCode");
objWriter.WriteString(nodeRoom ["RoomTypeCode"].InnerText);
objWriter.WriteEndElement();//RoomTypeCode
objWriter.WriteStartElement("Quantity");
objWriter.WriteString(nodeRoom ["Quantity"].InnerText);
objWriter.WriteEndElement();//数量
objWriter.WriteStartElement("NumberOfAdults");
objWriter.WriteString(nodeRoom ["NumberOfAdults"].InnerText);
objWriter.WriteEndElement();//成人数
objWriter.WriteStartElement("NumberOfChildren");
objWriter.WriteString(nodeRoom ["NumberOfChildren"].InnerText);
objWriter.WriteEndElement();//Numberofchildren
objWriter.WriteStartElement("PricePerRoom");
objWriter.WriteString(nodeRoom ["PricePerRoom"].InnerText);
objWriter.WriteEndElement();//PricePerRoom
objWriter.WriteStartElement("RateTypes");
XmlNodeList nodeRatePlans = nodeRoom.SelectNodes("Room/RateTypes/RateType"，ns);
foreach(nodeRatePlans中的XmlNode nodeRatePlan)
{
objWriter.WriteStartElement("RateType");
objWriter.WriteStartElement("Date");
objWriter.WriteString(CheckIn);
objWriter.WriteEndElement();//日期
objWriter.WriteStartElement("Price");
//将价格放在这里
objWriter.WriteEndElement();//价格
objWriter.WriteStartElement("RateTypeCode");
//将RateTypeCode放在此处
objWriter.WriteEndElement();//RateTypeCode
objWriter.WriteStartElement("BoardTypeCode");
//此处为PutBoardTypeCode
objWriter.WriteEndElement();//BoardTypeCode
objWriter.WriteEndElement();//RateType
}
objWriter.WriteEndElement();//RateTypes
objWriter.WriteEndElement();//Room
}
objWriter.WriteEndElement();//房间

费率计划是第二个节点列表.

请帮忙！
谢谢

I''m looping through an XML document that has two lists, so for example:

<xml>
<nodelist1 A>
<node1></node1>
<node2></node2>
<nodelist2 A>
<node3>
<node4>
</nodelist2>
</nodelist1>
<nodelist1 B>
<node1></node1>
<node2></node2>
<nodelist2 B>
<node3>
<node4>
</nodelist2>
</nodelist1>
</xml>

Looping through the first node list is fine, but I can''t get the second one to work.

Here is a code sample:
nodeRooms = xmlDoc.SelectNodes("/test:Reservation/test:Rooms/test:Room", ns);
foreach (XmlNode nodeRoom in nodeRooms)
{
objWriter.WriteStartElement("Room");
objWriter.WriteStartElement("RoomTypeCode");
objWriter.WriteString(nodeRoom["RoomTypeCode"].InnerText);
objWriter.WriteEndElement();//RoomTypeCode
objWriter.WriteStartElement("Quantity");
objWriter.WriteString(nodeRoom["Quantity"].InnerText);
objWriter.WriteEndElement();//Quantity
objWriter.WriteStartElement("NumberOfAdults");
objWriter.WriteString(nodeRoom["NumberOfAdults"].InnerText);
objWriter.WriteEndElement();//Numberofadults
objWriter.WriteStartElement("NumberOfChildren");
objWriter.WriteString(nodeRoom["NumberOfChildren"].InnerText);
objWriter.WriteEndElement();//Numberofchildren
objWriter.WriteStartElement("PricePerRoom");
objWriter.WriteString(nodeRoom["PricePerRoom"].InnerText);
objWriter.WriteEndElement();//PricePerRoom
objWriter.WriteStartElement("RateTypes");
XmlNodeList nodeRatePlans = nodeRoom.SelectNodes("Room/RateTypes/RateType", ns);
foreach (XmlNode nodeRatePlan in nodeRatePlans)
{
objWriter.WriteStartElement("RateType");
objWriter.WriteStartElement("Date");
objWriter.WriteString(CheckIn);
objWriter.WriteEndElement();//Date
objWriter.WriteStartElement("Price");
//Put Price Here
objWriter.WriteEndElement();//Price
objWriter.WriteStartElement("RateTypeCode");
//Put RateTypeCode Here
objWriter.WriteEndElement();//RateTypeCode
objWriter.WriteStartElement("BoardTypeCode");
//PutBoardTypeCode Here
objWriter.WriteEndElement();//BoardTypeCode
objWriter.WriteEndElement();//RateType
}
objWriter.WriteEndElement();//RateTypes
objWriter.WriteEndElement();//Room
}
objWriter.WriteEndElement();//Rooms

The rate plans is the second nodelist.

Please help!
Thanks

推荐答案

，您需要在问题中放入正确的xml文件.如果我们看不到您要遍历的确切xml数据，将很难帮助您进行故障排除.

you need to put the correct xml file in your question. its very hard to help you troubleshoot if we can''t see the exact xml data you are trying to traverse.

<?xml version="1.0" encoding="utf-8"?>
<Reservation xmlns="http://www.transhotel.com/transHotel/2004A"
