这是一个示例XML文件:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">Automation Test</string>
<string name="current_data_state_incoming_call">Incoming Call</string>
<string name="current_data_state_outgoing_call">Outgoing Call</string>
<string name="current_data_state_missed_call">Missed Call</string>
<string name="current_data_state_photo">Photo</string>
<string name="current_data_state_video">Video</string>
<string name="current_data_state_mp3">MP3</string>
<string name="current_data_state_voice_memo">Voice Memo</string>
<string name="current_data_state_phone_book">Phone Book</string>
<string name="current_data_state_phone_booksim">Phone Book(SIM)</string>
<string name="current_data_state_etc">Etc</string>
<string name="current_data_state_schedule">S Planner</string>
</resources>
我有一个大文件XML文件,我想根据原始值替换元素中的值。
例如,我想用另一个单词替换“拨出电话”。 我试过这段代码:
XmlDocument xdoc = new XmlDocument();
xdoc.Load("strings.xml");
XmlElement root = xdoc.DocumentElement;
XmlNodeList elemList = root.GetElementsByTagName("string");
for (int i = 0; i < elemList.Count; i++)
{
xdoc.Save("strings.xml");
if (elemList[i].InnerText == "Incoming Call")
{
// xdoc.LoadXml(File.ReadAllText("strings.xml").Replace(elemList[i].InnerText, "صندوق"));
// MessageBox.Show(elemList[i].InnerText);
elemList[i].SelectSingleNode("resources/string").InnerText="مكالمات قادمة";
xdoc.Save("strings.xml");
}
}
和此代码
XmlDocument xdoc = new XmlDocument();
xdoc.Load("strings.xml");
XmlNodeList aNodes = xdoc.SelectNodes("resources/string");
foreach (XmlNode node in aNodes)
{
XmlNode child1 = node.SelectSingleNode("string");
if(child1.InnerText == "Incoming Call")
{
child1.InnerText = "اتصالات قادمة";
}
}
xdoc.Save("strings.xml");
我无法替换该值。
=================================== thanx我解决了我的问题
var root2 = new XmlDocument();
root2.Load("strings.xml");
var root = new XmlDocument();
root.Load("strings2.xml");
foreach (XmlNode e1 in root2.GetElementsByTagName("string"))
{
string a = e1.Attributes["name"].Value;
foreach (XmlNode ee in root.GetElementsByTagName("string"))
{
string b = ee.Attributes["name"].Value;
if (a == b)
{
e1.FirstChild.Value = ee.FirstChild.Value;
}
}
}
root.Save("strings.xml");

我会使用LINQ to XML。它使各种事情比XmlDocument
简单得多。以下是执行替换的完整示例(加载input.xml
并撰写output.xml
):
using System;
using System.Linq;
using System.Xml.Linq;
class Test
{
static void Main()
{
XDocument doc = XDocument.Load("input.xml");
ReplaceValue(doc, "Outgoing Call", "Other value");
doc.Save("output.xml");
}
static void ReplaceValue(XDocument doc, string original, string replacement)
{
foreach (var element in doc.Descendants("string").Where(x => x.Value == original))
{
element.Value = replacement;
}
}
}
如果找不到您要替换的值,或者找到多个元素,您可以轻松更改方法以引发异常。
替换为 value 的替代方法是替换为name
属性,这将是一个微不足道的变化:
static void ReplaceNamedValue(XDocument doc, string name, string replacement)
{
foreach (var element in doc.Descendants("string")
.Where(x => (string) x.Attribute("name") == name))
{
element.Value = replacement;
}
}
然后你会这样称呼它:
ReplaceNamedValue(doc, "current_data_state_outgoing_call", "Other value");

您可能希望动态创建xml上的文件而不是替换。我更喜欢使用较新的Net库xml linq(XDocument)而不是旧版本的XmlDocument。以下是我将使用的代码示例:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string ident = "<?xml version=\"1.0\" encoding=\"utf-8\"?><resources></resources>";
XDocument doc = XDocument.Parse(ident);
XElement resources = doc.Root;
resources.Add(new XElement("string", new object[] {
new XAttribute("name","app_name"),
"Automation Test"
}));
resources.Add(new XElement("string", new object[] {
new XAttribute("name","current_data_state_incoming_call"),
"مكالمات قادمة"
}));
}
}
}
以下是替换代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = @"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement resource = doc.Root;
Dictionary<string, XElement> dict = resource.Elements()
.GroupBy(x => (string)x.Attribute("name"), y => y)
.ToDictionary(x => x.Key, y => y.FirstOrDefault());
if(dict.ContainsKey("app_name"))
{
dict["app_name"].SetValue("Automation Test");
}
if (dict.ContainsKey("current_data_state_incoming_call"))
{
dict["current_data_state_incoming_call"].SetValue("مكالمات قادمة");
}
}
}
}
