Pass:看公司代码，配置下拉框的功能，和下拉框的数字转文字。配置xml里面有下拉的value，name,这样界面直接显示数字，然后转译成中文
1.xml文件格式
<?xml version="1.0" encoding="utf-8"?>
<bookstore>
<book category="COOKING" id="">
<title lang="en">Everyday Italian</title>
<author>Giada De Laurentiis</author>
<year></year>
<price></price>
</book>
</bookstore>
2.认识xml的基本操作的几个基本概念
net操作xml有基本的XMLDocument、linq
2.1 XmlDocument : XmlDocument将XML视为树状结构，它装载XML文档，并在内存中构建该文档的树状结构。下面来看下XmlDocument提供了哪些功能。
2.2 XmlNode:节点
2.3 XmlElement:元素
2.4几个基本操作
获取节点的值：?.InnerText ;
获取节点的属性：?.Attributes["id"].InnerText ;
3.xml的增删改查
3.1 最基本
public book getModel()
{
//封装获取数据
book b = new book();
b.author = HttpContext.Current.Request["author"];
b.category = HttpContext.Current.Request["category"];
b.lang = HttpContext.Current.Request["lang"];
b.price = Convert.ToDouble(HttpContext.Current.Request["price"]);
b.title = HttpContext.Current.Request["title"];
b.year = Convert.ToInt16(HttpContext.Current.Request["year"]);
return b;
}
public List<book> readXMl()
{
List<book> ls = new List<book> { }; //1.载入xml
XmlDocument doc = new XmlDocument();
doc.Load(xmlPath); //2.获取文档下第一个子类的所以子类
XmlNodeList listNode = doc.SelectSingleNode("bookstore").ChildNodes; //3.遍历子类
foreach (XmlNode books in listNode)
{
book b = new book();
b.Id = Convert.ToInt16(books.Attributes["id"].InnerText);
b.category = books.Attributes["category"].InnerText;
b.title = books["title"].InnerText;
b.lang = books["title"].Attributes["lang"].InnerText;
b.author = books["author"].InnerText;
b.year = Convert.ToInt16(books["year"].InnerText);
b.price = Convert.ToDouble(books["price"].InnerText); ls.Add(b);
} return ls;
}
public book readXMLById()
{
book b = getModel(); //需要查询数据的Id
b.Id = Convert.ToInt16(HttpContext.Current.Request["id"]); XmlDocument root = new XmlDocument();
root.Load(xmlPath); XmlNode xml = root.SelectSingleNode("bookstore");
XmlNodeList listnode = xml.ChildNodes; //遍历bookstore下的节点
foreach (XmlNode i in listnode)
{
//获取每一个book的属性Id对比是否=需要查询的值
if (i.Attributes["id"].InnerText == b.Id.ToString())
{
b.category = i.Attributes[].InnerText;
b.title = i["title"].InnerText;
b.lang = i["title"].Attributes["lang"].InnerText;
b.author = i["author"].InnerText;
b.year = Convert.ToInt16(i["year"].InnerText);
b.price = Convert.ToDouble(i["price"].InnerText);
}
} return b; }
public bool WriteXml()
{
bool isValue = false;
try
{
//设置模型类，只是为了更好的看到数据
book b = getModel(); //创建xml文件
XmlDocument xml = new XmlDocument();
xml.Load(xmlPath); //*树
XmlNode root = xml.SelectSingleNode("bookstore");
int id = Convert.ToInt16(root.LastChild.Attributes["id"].InnerText) + ; //二级子节点
XmlElement node = xml.CreateElement("book");
node.SetAttribute("category", b.category);
node.SetAttribute("id", id.ToString()); //三级子节点
XmlElement n1 = xml.CreateElement("title");
n1.SetAttribute("lang", b.lang);
n1.InnerText = b.title; XmlElement n2 = xml.CreateElement("author");
n2.InnerText = b.author; XmlElement n3 = xml.CreateElement("year");
n3.InnerText = b.year.ToString(); XmlElement n4 = xml.CreateElement("price");
n4.InnerText = b.price.ToString(); //三级添加到二级
node.AppendChild(n1);
node.AppendChild(n2);
node.AppendChild(n3);
node.AppendChild(n4); //二级添加到一级
root.AppendChild(node); //把文件保存到路径
xml.Save(xmlPath);
isValue = true;
}
catch (Exception e)
{
HttpContext.Current.Response.Write(e);
}
return isValue; }
public bool delXMLById()
{
bool isValue = false;
book b = getModel();
b.Id = Convert.ToInt16(HttpContext.Current.Request["id"]);
//以上为获取数据 XmlDocument root = new XmlDocument();
root.Load(xmlPath); XmlNode xml = root.SelectSingleNode("bookstore");
XmlNodeList listnode = xml.ChildNodes;
foreach (XmlNode i in listnode)
{
if (i.Attributes["id"].InnerText.ToString() == b.Id.ToString())
{
xml.RemoveChild(i);
root.Save(xmlPath);
isValue = true;
}
} return isValue;
}
public bool upXMLByModel()
{
book b = getModel();
bool isValue = false;
b.Id = Convert.ToInt16(HttpContext.Current.Request["id"]);
//以上为获取数据：request[""] XmlDocument root = new XmlDocument();
root.Load(xmlPath);
XmlNode xml = root.SelectSingleNode("bookstore");
XmlNodeList xs = xml.ChildNodes; foreach (XmlNode x in xs)
{
if (x.Attributes["id"].InnerText.ToString() == b.Id.ToString())
{
XmlElement node = x as XmlElement;
node.SetAttribute("category", b.category); //三级树
XmlElement n1 = node.SelectSingleNode("title") as XmlElement;
n1.SetAttribute("lang", b.lang);
n1.InnerText = b.title; XmlElement n2 = node.SelectSingleNode("author") as XmlElement;
n2.InnerText = b.author; XmlElement n3 = node.SelectSingleNode("year") as XmlElement;
n3.InnerText = b.year.ToString(); XmlElement n4 = node.SelectSingleNode("price") as XmlElement;
n4.InnerText = b.price.ToString(); root.Save(xmlPath);
isValue = true;
}
}
return isValue;
}
