Question

我想基于文本限定符分割字符串，例如

"1","10411721","MikeTison","08/11/2009","21/11/2009","2800.00","002934538","051","New York","10411720-002",".\Images\b.jpg",".\RTF\b.rtf"

限定符= " Spliter = ,

我想基于Spliter ,拆分字符串，但是如果Spliter在限定符"内部而不是忽略它并返回包含Spliter的字符串。

我正在使用的正则表达式为(?:|,)(\"(?:[^\"]+|\"\")*\"|[^,]*)

但是这个正则表达式只返回逗号，请从这个角度帮助我，因为我是正则表达式的新手

请注意，如果我们在字符串中有换行符，即\r\n，则应忽略换行符

"1","10411","Muis","a","21/11/2009","2800.06","0029683778","03005136851","Awan","10411720-001",".\Images\a.jpg",".\RTF\a.rtf"

Answer 1

可能最简单的解决方案不是搜索split的位置，而是搜索要返回的find元素。在你的情况下这些元素

启动"
以"
里面没有"。

所以你试试像

这样的东西

String data = "\"1\",\"10411721\",\"MikeTison\",\"08/11/2009\",\"21/11/2009\",\"2800.00\",\"002934538\",\"051\",\"New York\",\"10411720-002\",\".\\Images\\b.jpg\",\".\\RTF\\b.rtf\"";

Pattern p = Pattern.compile("\"([^\"]+)\"");
Matcher m = p.matcher(data);
while(m.find()){
    System.out.println(m.group(1));
}

输出：

1
10411721
MikeTison
08/11/2009
21/11/2009
2800.00
002934538
051
New York
10411720-002

Answer 2

删除整个字符串的第一个和最后一个字符。然后用＆＃34;，＆＃34;

分开

outputVideo.open(name, CV_FOURCC('M', 'J', 'P', 'G'), 25, size, true); // create a new videoFile with 25fps

Answer 3

您可以使用此正则表达式进行拆分：

String[] arr = input.split( "(?=(([^\"]*\"){2})*[^\"]*$),+" );

如果这些正则表达式使用前瞻以确保在逗号后面有偶数引号，那么这些正则表达式将在逗号上分割，如果它们在双引号之外。

Answer 4

即使您有新的线条字符，它仍然有效。

    String str="\"1\",\"10411721\",\"MikeTison\",\"08/11/2009\",\"21/11/2009\",\"2800.00\",\"002934538\",\"051\",\"New York\",\"10411720-002\",\".\\Images\\b.jpg\",\".\\RTF\\b.rtf\"";
    System.out.println(Arrays.toString(str.split(",(?=([^\"]*\"[^\"]*\")*[^\"]*$)")));
