macos - 如何将 CSV 转换为多个列表(applescript)？

Question

我已经研究了一段时间，但找不到解决方案。我有一个 CSV 文件，其中包含以下数据:

1,2,3,a,b,c,4,5,6,d,e,f,7,8,9,0
0,9,8,g,h,i,7,6,4,k,l,m,5,4,3,2
等等...

除了某些为真或为假的字段外，每一行都包含大部分不同的数据。

我需要的是将每一行作为列表拉出，然后能够解析数据。

我希望能够从所有列表中删除项目编号 3，然后保存要在电子表格中使用的数据。

请记住，我对 applescript 比较陌生，所以仍在尝试掌握它，已经购买了一本在许多网站上强烈推荐的书，但它还没有交付! :-)

此外，如果您知道一种不同/更好的方法，那么我很乐意尝试。

目前我有以下内容:

Blockquote -- Setting Variables
set LF to ASCII character 10
-- Choosing your files
set prompt1 to "Please locate your Devices CSV file..."
set csvDevices to "testfile.csv"
--set csvDevices to (choose file with prompt prompt1)
-- Reading file to memory
set csvLines to read csvDevices
set AppleScript's text item delimiters to {LF}
set csvEntries to paragraphs of csvLines
set AppleScript's text item delimiters to {","}
-- Filtering rubbish
set csvNoTitle to rest of csvEntries -- Remove Title Line
set lineCount to count csvNoTitle

之后我可以打印出内容，但它会给我

{"1,2,3,a,b,c,4,5,6,d,e,f,7,8,9,0","0,9,8,g,h,i ,7,6,4,k,l,m,5,4,3,2","等..."}

而不是我想要的

{"1","2","3","a","b","c","4","5","6","d","e","f ","7","8","9","0"}
{"0","9","8","g","h","i","7","6","4","k","l","m","5","4","3","2"}
{“等等...”}

顺便说一下，我删除了脚本中的第一行，因为它是没有实际有用数据的描述行，或者无论如何对我来说都不是。

感谢您的帮助

您应该将文本 CSV 文件分解为记录(单行)，然后将每个记录分解为值(以逗号分隔)。您可以从将 CSV 文本文件转换为字符串 (csvLines) 开始按照这种方式进行。

-- getting records (you don't need to set applescript's text item delimiters here)
set recs to paragraphs of csvLines

-- getting values for each record
set vals to {}
set applescript's text item delimiters to ","
repeat with i from 1 to length of recs
    set end of vals to text items of (item i of recs)
end repeat

-- this is true
(item 1 of vals) = {"1","2","3","a","b","c","4","5","6","d","e","f","7","8","9","0"} 

这将解析整个文件而不进行过滤。但只是给出正确的 CSV 解析的想法。您已经知道如何过滤数据。
