c# 获取xml节点

[wanglaibing]

<?xml version="1.0" encoding="utf-8"?>
<CRM_Dictionary>
<Service_Score>
<sort>3</sort>
<default>false</default>
<enalbe>false</enalbe>
<content>东北区</content>
</Service_Score>
<Client_Area>
<sort>0 </sort>
<default_>false </default_>
<enable>false </enable>
<content>sdfad </content>
</Client_Area>
<Client_Area>
<sort>1 </sort>
<default_>false </default_>
<enable>true </enable>
<content>asdfsad </content>
</Client_Area>
<Client_Area>
<sort>2 </sort>
<default_>false </default_>
<enable>false </enable>
<content>asdfasd </content>
</Client_Area>
<Client_Area>
<sort>3 </sort>
<default_>true </default_>
<enable>false </enable>
<content>3434343434 </content>
</Client_Area>
</CRM_Dictionary> ---这是我的xml

我如何用vs2008 获取所有节点Client_Area的值

[liujintaozyc]

你又用dom
创建一个dom
上网查查
网上比较多

[huming_h]

XElement doc = XElement.Load("tt.xml");
var v = from s in doc.Descendants("Client_Area")
select s.Value;
foreach(string s in v)
{
Console.WriteLine(s);
}

用linq to xml 来实现
引入命名空间using System.Xml.Linq;

[wanglaibing]

我查了好多的资料,可没有找到我相同的!!!
帮忙啊

Set oDoc = CreateObject("Msxml2.DOMDocument")

.async = False
.validateOnParse = False

.load "c:\xxx.xml"
If .parseError.errorCode <> 0 Then
sErrMsg = .parseError.errorCode & "|" &_
.parseError.srcText & "|" & .parseError.reason
Err.Raise 62002, "Create", sErrMsg
End If
Set oNodes = .selectNodes("//Client_Area")
For i=0 To oNodes.length-1
Set oNode = oNodes(i).selectSingleNode("sort")
Response.Write oNode.text
Set oNode = oNodes(i).selectSingleNode("default_")
Response.Write oNode.text
Set oNode = oNodes(i).selectSingleNode("enable")
Response.Write oNode.text
Set oNode = oNodes(i).selectSingleNode("content")
Response.Write oNode.text
Next

这是一位牛哥用asp给我发的,可我好象用C#弄不了,有哪位牛哥把这个改成C#的

[/Quote]

这个using System.Xml.Linq;我放在程序里报错,说这个命名空间不存在

[huming_h]

ling 需要framework3.5的支持
你不是用vs2008建的项目吗？难道没有还是用的framework2.0

[wanglaibing]

大哥
from s in myDoc.Descendants("Client_Area")
这里的Descendants这个过不去

[huming_h]

如果你没有引用命名空间，肯定是会报错的。我在我本地都运行过了，代码没有问题。

}
}
}
}

这个过不去啊!!!

[huming_h]

XElement doc = XElement.Load("tt.xml"); //你需要加载xml文件

[wanglaibing]

public manage_AddCRM_CRMDictionary()
{
//构造函数
myDoc = new XmlDocument();
myDoc.Load(Server.MapPath("../../Config/CRM_Dictionary.xml"));
}
我在构造时就加了

[huming_h]

不要用XmlDocument，是XElement

[wanglaibing]

using System.Xml;
using System.IO;
using System.Xml.Linq;
using System.Xml.Schema;
using System.Xml.XPath;
using System.Xml.Xsl;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack) {
labe = repeater1.Items.Count;
XDocument xmlFile = XDocument.Load("../../Config/CRM_Dictionary.xml");
var query = from c in xmlFile.Elements("CRM_Dictionary").Elements("sort")
select c;
foreach (XElement book in query)
{
Console.WriteLine(book.Value.ToString());
}
}
}

这样还是不行,!!!

[huming_h]

你想要什么样的结果？？？
我晕。我给你的代码不是这个样子的啊
var v = from s in doc.Descendants("Client_Area")
select s;
foreach(string s in v)
{
Console.WriteLine(s);
}

[wanglaibing]

using System.Xml;
using System.IO;
using System.Xml.Linq;
using System.Xml.Schema;
using System.Xml.XPath;
using System.Xml.Xsl;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack) {
XElement doc = XElement.Load("../../Config/CRM_Dictionary.xml");
var v = from s in doc.Descendants("Client_Area")
select s.Value;
foreach (string s in v)
{
Console.WriteLine(s);
}
}
}
报:当前上下文不存在 XElement

[huming_h]

你的是web的项目吧。请在Load的地方用 XElement.Load(Server.MapPath("~/Config/CRM_Dictionary.xml"));

[wanglaibing]

是,还是不行!!!
谢大哥你了,我找下别的方法,
用XmlDocument

这是C#3.0的LINQ
如果你VS不支持的话，先添加System.Xml.Linq程序集的引用，然后再添加using System.Xml.Linq;
没有这个上面那个DLL可以下个，呵呵
