使用C＃查找和替换XML文件中的文本 [英] Find and Replace text in XML file using c#

问题描述

我正在尝试使用c＃查找和替换xml文件中的文本。我想要的是在整个文件的url链接中更改服务器名称。

I am trying to find and replace text in an xml file using c#. What I want is to change server name in the url link throughout the file.

http://Server1.extranet.abc/server1webdev/rest/services/ABC/ABC_Base/MapServer

至

http://Server2.extranet.abc/server1webdev/rest/services/ABC/ABC_Base/MapServer 

我尝试使用
System.xml.linq（XDocument.load（xmlpath））
，但这只是将整个xml文件作为一个字符串行。有没有办法替换文本？请注意，网址不在特定的节点中。它们在整个文件中都是随机的。我可以通过文件的查找和替换来手动执行此操作，有没有办法以编程方式执行此操作？

I tried using System.xml.linq (XDocument.load(xmlpath)) but it simply gives me the whole xml file as one line of string. Is there a way I can replace the text?Note that the url's are not in specific nodes., they are random throughout file. I am able to do this manually through the file's find and replace, is there a way of doing this programmatically?

推荐答案

将整个xml文件作为字符串，您可以通过执行以下操作替换所需的内容：

if you have the entire xml file as string you can replace what you need by doing:

string oldStr = @"http://Server1.extranet.abc/server1webdev/rest/services/ABC/ABC_Base/MapServer";
string newStr = @"http://Server2.extranet.abc/server1webdev/rest/services/ABC/ABC_Base/MapServer ";

doc.Replace(oldStr, newStr);

但是通常如果您想在xml中更改标记的值，我可以举一个例子，您放在XML中使用它：

but normally if you want to change a value of a tag in xml i can suggest an example and you put it to use in your xml:

     XDocument doc = XDocument.Load("D:\\tst.xml");
     foreach (XElement cell in doc.Element("Actions").Elements("Action"))
     {
        if (cell.Element("ActionDate").Value == oldStr)
        {
           cell.Element("ActionDate").Value = newStr;
        }
     } 

     doc.Save("D:\\tst.xml");
