删除列表中包含单词的字符串我有一个文件名列表，我想从中选择某些文件。 前 4 位数字是年份，下划线充当分隔符，“abc”只是文件类型的标识符，后 3 位数字是 id，“摘要”或“结果”指的是文件类型文件。
首先，我只想查看“结果”文件。 我不知道如何从列表中删除所有“摘要”文件。
{"2021_abc_027_result.csv", "2021_abc_027_summary.csv", "2021_abc_028_result.csv",
"2021_abc_028_summary.csv", "2021_abc_029_result.csv", "2021_abc_029_summary.csv",
"2021_abc_038_result.csv", "2021_abc_038_summary.csv", "2021_abc_040_result.csv",
"2021_abc_040_summary.csv", "2021_abc_041_result.csv", "2021_abc_041_summary.csv",
"2021_abc_042_result.csv", "2021_abc_042_summary.csv", "2021_abc_043_result.csv",
"2021_abc_043_summary.csv", "2021_abc_044_result.csv", "2021_abc_044_summary.csv",
"2021_abc_045_result.csv", "2021_abc_045_summary.csv", "2021_abc_046_result.csv",
"2021_abc_046_summary.csv", "2021_abc_047_result.csv", "2021_abc_047_summary.csv",
"2021_abc_048_result.csv", "2021_abc_048_summary.csv", "2021_abc_049_result.csv",
"2021_abc_049_summary.csv", "2021_abc_050_result.csv", "2021_abc_050_summary.csv",
"2021_abc_051_result.csv", "2021_abc_051_summary.csv", "2021_abc_052_result.csv",
"2021_abc_052_summary.csv", "2021_abc_053_result.csv", "2021_abc_053_summary.csv",
"2021_abc_054_result.csv", "2021_abc_054_summary.csv", "2021_abc_055_result.csv",
"2021_abc_055_summary.csv", "2021_abc_056_result.csv", "2021_abc_056_summary.csv",
"2021_abc_057_result.csv", "2021_abc_057_summary.csv", "2021_abc_058_result.csv",
"2021_abc_058_summary.csv", "2021_abc_059_result.csv", "2021_abc_059_summary.csv",
"2021_abc_060_result.csv", "2021_abc_060_summary.csv", "2021_abc_061_result.csv",
"2021_abc_061_summary.csv", "2021_abc_062_result.csv", "2021_abc_062_summary.csv",
"2021_abc_063_result.csv", "2021_abc_063_summary.csv", "2021_abc_064_result.csv",
"2021_abc_064_summary.csv", "2021_abc_065_result.csv", "2021_abc_065_summary.csv",
"2021_abc_067_result.csv"}
其次，我想根据年份和 3 位数代码选择文件。
我过去做过类似的事情来使用正则表达式选择文件，其中字符串中只有一个数字，所以我使用
For( i = 1, i <= N Items( FileList ), i++,
FileList[i] = regex(FileList[i], "([0-9]+)", "\1")
);
但在这种情况下，我最终得到了“2021”、“2021”、...的列表
理想情况下，我最终会得到一个看起来像这样的列表
{"2021_027 ", "2021_027 ", "2021_028 ",
"2021_028 ", "2021_029 ", "2021_029 ",
"2021_038 ", "2021_038 ", "2021_040 ",
"2021_040 ", "2021_041 ", "2021_041 ",
"2021_042 ", "2021_042 ", "2021_043 ",
"2021_043 ", "2021_044 ", "2021_044 ",
"2021_045 ", "2021_045 ", "2021_046 ",
"2021_046 ", "2021_047 ", "2021_047 ",
"2021_048 ", "2021_048 ", "2021_049 ",
"2021_049 ", "2021_050 ", "2021_050 ",
"2021_051 ", "2021_051 ", "2021_052 ",
"2021_052 ", "2021_053 ", "2021_053 ",
"2021_054 ", "2021_054 ", "2021_055 ",
"2021_055 ", "2021_056 ", "2021_056 ",
"2021_057 ", "2021_057 ", "2021_058 ",
"2021_058 ", "2021_059 ", "2021_059 ",
"2021_060 ", "2021_060 ", "2021_061 ",
"2021_061 ", "2021_062 ", "2021_062 ",
"2021_063 ", "2021_063 ", "2021_064 ",
"2021_064 ", "2021_065 ", "2021_065 ",
"2021_067 "}然后我可以从该列表中选择我想要使用的文件。
另外，欢迎任何有关学习如何更好地正则表达式的提示。
谢谢你！
高级统计建模消费者和市场研究质量和工艺工程分享和交流结果回复：删除列表中包含单词的字符串三大优质解决方案：
@蒂埃里_S - 易于理解和维护
@乔治- 正则表达式替换的具体使用方式
@gzmorgan0 - 通过向后工作有效地从列表中删除
您可以混合搭配这些想法，以制定一个易于维护、高效且清楚地代表您正在解决的问题的理想解决方案。
回复：删除列表中包含单词的字符串这是另一种方法。我喜欢使用 RegexMatch(SourceStr, patStr) 函数。点星号 (.*) 类似于在 Like 数据库函数中使用 %。由于您希望从列表中删除项目，因此需要从列表末尾开始，否则索引会损坏。

这是解决您的问题的一种强力方法，它绕过了使用正则表达式的需要（我不太擅长这些）。

Show (ResultList); // Yields a clean list with results only
FileList = {};
For (i= 1 , i <= N Items (ResultList), i++,
Insert into (FileList, Word (1, ResultList [i], "_") || "_" || Word (3, ResultList [i], "_"))
);
Show (FileList); // Yields the file Year and Numerical ID
然后，您可以使用该列表将其输入 ListBox 或使用 Contains () 函数直接检索相应的文件。
