遍历子列表

本文介绍了遍历子列表-XMLNodeList的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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 James

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 James

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="www.transhotel/transHotel/2004A" xmlns:xsi="www.w3/2001/XMLSchema-instance" xsi:schemaLocation="www.transhotel/transHotel/2004A ReservationRQ.xsd"> <WholesalerID>TRANSHOTEL</WholesalerID> <Product>1</Product> <ID>28610294</ID> <CommitLevel>1</CommitLevel> <HotelCode>1154718</HotelCode> <CheckIn>2010-04-21</CheckIn> <CheckOut>2010-04-22</CheckOut> <CustomerName>availability search only</CustomerName> <Remarks /> <TotalPrice>300.0</TotalPrice> <Currency>GBP</Currency> <Rooms> <Room> <RoomTypeCode>SDBL</RoomTypeCode> <Quantity>1</Quantity> <NumberOfAdults>2</NumberOfAdults> <NumberOfChildren>0</NumberOfChildren> <PricePerRoom>120.0</PricePerRoom> <PricePerBoard>0.0</PricePerBoard> <RateTypes> <RateType> <RateTypeCode>XX</RateTypeCode> <BoardTypeCode>DE</BoardTypeCode> <BoardPrice>0.0</BoardPrice> <Price>120.0</Price> <Date>2010-04-21</Date> </RateType> </RateTypes> </Room> <Room> <RoomTypeCode>STTP</RoomTypeCode> <Quantity>1</Quantity> <NumberOfAdults>3</NumberOfAdults> <NumberOfChildren>0</NumberOfChildren> <PricePerRoom>180.0</PricePerRoom> <PricePerBoard>0.0</PricePerBoard> <RateTypes> <RateType> <RateTypeCode>XX</RateTypeCode> <BoardTypeCode>DE</BoardTypeCode> <BoardPrice>0.0</BoardPrice> <Price>180.0</Price> <Date>2010-04-21</Date> </RateType> </RateTypes> </Room> </Rooms> </Reservation>
