哦，你不能这么容易地自己修复这种输入。正则表达式会进一步破坏你的数据。

你能在Java中创建一个小脚本来处理这个问题吗？如果你这样做了，然后使用uniVardy-parser来读取你的CSV输入，并用正确的引号转义写回它：

这是唯一一个可以处理断引号转义的CSV解析器。请尝试以下示例：

import com.univocity.parsers.csv;

import java.io.*;
import java.util.*;

public class Test {

    public static void main(String ... args){
        CsvParserSettings settings = new CsvParserSettings();
        settings.getFormat().setLineSeparator("\r\n");
        settings.setParseUnescapedQuotes(true); // THIS IS IMPORTANT FOR YOU
        CsvParser parser = new CsvParser(settings);

        String line1 = "something,\"a quoted value \"with unescaped quotes\" can be parsed\", something\r\n";
        System.out.println("Input line: " + line1);

        String line2 = "\"after the newline \r\n you will find \" more stuff\r\n";
        System.out.println("Input line: " + line2);

        List<String[]> allInputLines = parser.parseAll(new StringReader(line1 + line2));

        System.out.println("===============\nParsed input values\n===============");
        int count = 0;
        for(String[] line : allInputLines){
            System.out.println("From line " + ++count + ":");
            for(String element : line){
                System.out.println("\t" + element);

            }
            System.out.println();
        }

        //Let's write your output CSV
        StringWriter output = new StringWriter();
        CsvWriterSettings writerSettings = new CsvWriterSettings();
        writerSettings.getFormat().setLineSeparator("\r\n");
        writerSettings.getFormat().setQuoteEscape('\\'); //it seems you are using backslash as quote escape
        writerSettings.getFormat().setCharToEscapeQuoteEscaping('\\'); //when your quote escape character is not the same as the quote character, you might need to escape the escape character as well
        writerSettings.setQuoteAllFields(true); //let's force quotes on all fields so whatever is parsing your input file has more  chance of doing it properly
        CsvWriter writer = new CsvWriter(output, writerSettings);

        for(String[] row : allInputLines){
            writer.writeRow(row);
        }
        writer.close();

        System.out.println("===============\nNicely formatted output\n===============");
        System.out.println(output.toString());

    }

}

此代码将产生以下输出(可能会被您的数据导入工具读取):

Input line: something,"a quoted value "with unescaped quotes" can be parsed", something

Input line: "after the newline 
you will find " more stuff

===============
Parsed input values
===============
From line 1:
    something
    a quoted value "with unescaped quotes" can be parsed
    something

From line 2:
    after the newline 
you will find " more stuff


===============
Nicely formatted output
===============
"something","a quoted value \"with unescaped quotes\" can be parsed","something"

"after the newline 
 you will find \" more stuff"
