【问题】

I have a csv file that looks like this:

"first", "abc", "def", "last"
"111", "abc", "p"roblem", "last"
"aaa", "abc", "456", "last"

As you can see the second row has an extra double quote in text.

I am using below constructor:

reader = new CSVReader(new FileReader("temp.csv"), ',', '"', '|', 1);

Program fails because of that extra " in 2nd row.

How can I workaround this problem. I can't change the csv.

Thanks.

       如果无法用opencsv解决，可以试试SPL：

	A
1	file("D:\\data.csv").import@tcq()=
2	=A1.run(replace(def,"\"",""):def)
3	=A2.select(def=="problem")

A1：读取csv文件的内容并去掉字符串两端的引号，结果如下：

A2：去掉def列那个不合法字符串中的引号：

A3：查询def列中等于problem的数据，结果如下：

标签：abc,last,extra,含有,特殊字符,problem,csv,def
