我試圖找到一個正則表達式與CSV文件（用雙引號括起來的值）的值可以包含任何字符。我現在使用的表達（在Java中，因此反斜槓轉義）：CSV正則表達式的引用和反斜槓

",(?=(([^\"\\\\]|\\\\.)*\"([^\"\\\\]|\\\\.)*\")*([^\"\\\\]|\\\\.)*$)"

我和條目，如「random_value」」或‘random_value \’遇到的問題

。附加信息：

"000000000000000","","","","[email protected]","random_value"" 
"000000000000000","","","","[email protected]","random_value\"

貴國是否能因爲'與CSV'作品表達期望的輸出可能輸入的例子太含糊不清（至少對我而言）。 – Pshemo

考慮使用CSV解析而不是使用複雜的正則表達式。 – anubhava

「random_value」「作爲值是迴避csv，但」random_value \「」是合法的。以及csv不是一個明確的標準:) –

說明

那麼假設我們清理你的源文本，包括適當的收盤報價，那麼這個表達式：

匹配所有報價逗號分隔的文本
捕捉龍頭逗號和報價，並與包括文字收盤報價，沿成組0
切去領導對引號和地點的價值爲捕獲組1
允許值包含像\"和""

逃脫報價序列。

(?:^|,)"((?<=")(?:[^"]*|\\"|"")*?)"(?=[,\r\n]|\Z)

示例文字

"1000000000000000","","","","[email protected]","1random_value""" 
"2000000000000000","","","","[email protected]","2random_value\""

個捕捉組

[0][0] = "1000000000000000" 
[0][1] = 1000000000000000 

[1][0] = ,"" 
[1][1] = 

[2][0] = ,"" 
[2][1] = 

[3][0] = ,"" 
[3][1] = 

[4][0] = ,"[email protected]" 
[4][1] = [email protected] 

[5][0] = ,"1random_value""" 
[5][1] = 1random_value"" 

[6][0] = "2000000000000000" 
[6][1] = 2000000000000000 

[7][0] = ,"" 
[7][1] = 

[8][0] = ,"" 
[8][1] = 

[9][0] = ,"" 
[9][1] = 

[10][0] = ,"[email protected]" 
[10][1] = [email protected] 

[11][0] = ,"2random_value\"" 
[11][1] = 2random_value\"

Using JavaCSV：

String str = "\"000000000000000\",\"\",\"\",\"\",\"[email protected]\",\"random_value\\\"\""; 
CsvReader reader = CsvReader.parse(str); 
reader.readRecord(); 
for (int i=0; i<reader.getColumnCount(); i++) 
    System.out.printf("Scol[%d]: [%s]%n", i, reader.get(i));

OUTPUT：

Scol[0]: [000000000000000] 
Scol[1]: [] 
Scol[2]: [] 
Scol[3]: [] 
Scol[4]: [[email protected]] 
Scol[5]: [random_value\"]
