我正在学习使用C#。我有一个文件window_dump.xml。我需要将所需的数据提取到一个特定的列表中，如下所示：
text="界限＝"；[0,0][10802076]">
text="不是你吗"界限＝"；[4371900][6431983]">
text="注销"|界限＝"；[4571983][622058]">
text="quot|界限＝"；[0264][10802076]">
这是xml文件的全部内容：window_dump.xml

正如建议的那样，这种情况可以使用文件层次结构来解决。由于我无法完全理解xml的层次结构，我想出了另一种方法：读取、搜索和替换该文件中的字符串。
这是我尝试过的一个简单的控制台应用程序(测试并运行；从文件中提取文本、边界和索引(：
internal class Program
{
internal static void Main(string[] args)
{
// Load file content
Console.WriteLine("Please specify input file...");
string? filePath = (@"" + Console.ReadLine()).Replace(@"""", null);
if (filePath == null || (!File.Exists(filePath)))
throw new ApplicationException("Specified file is not valid.");
string content = File.ReadAllText(filePath);
// Create a list<T> for each key you want extract
List<string> texts = new();
List<string> bounds = new();
List<int> indexes = new();
// ...
// Call ExtractValues for each key you want extract
ExtractValues(ref content, "text", ref texts);
ExtractValues(ref content, "bounds", ref bounds);
ExtractValues(ref content, "index", ref indexes);
// ...
// JOB DONE!
// Do whatever you want with the lists (you could match the results in one single struct, for example)
}
private static void ExtractValues<T>(ref string fileContent, string findKey, ref List<T> targetList)
{
// Extract the sequence (e.g. SampleKey="sampleValue")
int sequenceStart = fileContent.IndexOf(findKey);
int valueStart = fileContent.IndexOf(@"""", sequenceStart + 1);
int fullLength = fileContent.IndexOf(@"""", valueStart + 1) + 1 - sequenceStart;
string fullSequence = fileContent.Substring(sequenceStart, fullLength);
// Extract the value (e.g. sampleValue)
string value = fullSequence[(findKey.Length + 2)..(fullSequence.Length - 1)];
// Add the value to the provided list, casting to T
targetList.Add((T)Convert.ChangeType(value, typeof(T)));
// Remove the sequence examinated so that the next run will find the next occurrence.
fileContent = fileContent.Remove(sequenceStart, fullLength);
// If there are still other occurrences of the same key, repeat recursively.
if (fileContent.IndexOf(findKey) > 0)
ExtractValues(ref fileContent, findKey, ref targetList);
}
}
也许这不是最优雅或最强大的解决方案，但它能完成任务，如果我需要的话，我会尝试它。
