我有一个XML文件,其中包含一些有关从exe启动应用程序的信息。喜欢:
<details>
C:\Program Files\...\abc.exe -env env -direnv direnv
</details>
我需要拆分为exe路径的第一部分,其余部分作为参数。但是当我按空格分开时,我只会得到C:\Program
。是否有另一种解决方案来实现输出为:
string [0] = C:\ Program Files ... \ abc.exe
字符串[1] = -env env -direnv
direnv
编辑用于从XML提取的代码:
XMLNodeLst = GetNodeFromXML().SelectNodes("Path");
if (XMLNodeLst != null)
{
foreach (XmlNode xmlNode in XMLNodeLst)
{
foreach (XmlNode pathNode in xmlNode.ChildNodes)
{
Match m = Regex.Match(source, pathNode.Name, RegexOptions.IgnoreCase);
if (m.Success)
{
installPath = pathNode.InnerText.Trim();
break;
}
else
{
logs.Error("No corresponding value in settings for the provided source name. Please check again!");
MessageBox.Show("No corresponding value in settings for the provided source name. Please check again!");
Environment.Exit(-1);
}
}
}
}
XML:
<?xml version="1.0" encoding="utf-8" ?>
<Path>
<details>
C:\Program Files\...\abc.exe -env env -direnv direnv
</details>
</Path>
要拆分:
string[] configs = installPath.Trim().Split(' ');
exePath = configs[0];
exeArgs = installPath.Remove(0, installPath.IndexOf(' ') + 1);

可用于解析字符串的类的示例:
public class ArgumentPathResult {
public string Path;
public List<string> Arguments = new List<string>();
}
// Define other methods and classes here
public static class ArgumentPathParser {
public static ArgumentPathResult ParsePath(string path) {
ArgumentPathResult result = new ArgumentPathResult();
string resultString = "";
foreach(char c in path){
resultString += c;
if(resultString.Contains(".exe")){
break;
}
}
result.Path = resultString;
result.Arguments = path.Replace(resultString, "")
.Split('-')
.Skip(1)
.ToList();
return result;
}
}
用法示例:
string path = @"C:\Program Files\...\abc.exe -env env -direnv direnv";
ArgumentPathResult result = ArgumentPathParser.ParsePath(path);
结果对象将包含您的Path作为一个变量,以及参数和值对"env env"
和"direnv direnv"
的列表

您可能会在正向查找和正向查找之间进行拆分,以断言左侧是.exe
,后跟一个空格,右边是一个破折号,后跟1+个非空白字符:
(?<=\.exe) (?=-\S+)
var installPath = @"C:\Program Files\...\abc.exe -env env -direnv direnv";
string[] configs = Regex.Split(installPath, @"(?<=\.exe) (?=-\S+)");
var exePath = configs[0];
Console.WriteLine(exePath); // C:\Program Files\...\abc.exe
请参见C# demo

var splitted = pathNode.InnerText.Trim()
.Split(new string[] { ".exe " }, StringSplitOptions.None);
var path = splitted[0] + ".exe";
var args = splitted[1];
