java - 正则表达式转义字符

Question

我必须将一大堆电子邮件和姓名分开，我必须用逗号分隔，但有些姓名中有逗号，所以我必须先处理它。幸运的是，名字在“引号”之间。

例如，目前我的正则表达式输出是这样的(编辑:它不会在我看到的论坛中显示电子邮件!):

"Talboom, Esther"

"Wolde, Jos van der"

"Debbie Derksen"  <deberken@casema.nl>,   corine  <corine5@xs4all.nl>, "

最后一个出错了，因为名字没有逗号，所以它会继续，直到找到一个，这就是我想用来分隔的那个。所以我希望它一直查找直到找到“<”。我该怎么做？

import java.util.regex.Pattern;
import java.util.regex.Matcher;

String test = "\"Talboom, Esther\" <E.Talboom@wegener.nl>,     \"Wolde, Jos van der\" <J.vdWolde@wegener.nl>,   \"Debbie Derksen\"  <deberken@casema.nl>,   corine  <corine5@xs4all.nl>, \"Markies Aart\" <A.Markies@wegenernieuwsmedia.nl>";

Pattern pattern = Pattern.compile("\".*?,.*?\"");

Matcher matcher = pattern.matcher(test);

boolean found = false;
while (matcher.find ()) {
  System.out.println(matcher.group());
}

编辑:更好的工作方式，因为并非所有人都有名字或引号:

String test = "\"Talboom, Esther\" <E.Talboom@wegener.nl>,     DRP - Wouter Haan <wouter@drp.eu>, \"Wolde, Jos van der\" <J.vdWolde@wegener.nl>,   \"Debbie Derksen\"  <deberken@casema.nl>,   corine  <corine5@xs4all.nl>, clankilllller@gmail.com, \"Markies Aart\" <A.Markies@wegenernieuwsmedia.nl>";

我会使用 String.split 和 String.replaceAll 来简化代码。这避免了使用 Pattern 的麻烦，并使代码简洁明了。
试试这个:

public static void main(String[] args) {
    String test = "\"Talboom, Esther\" <E.Talboom@wegener.nl>,     \"Wolde, Jos van der\" <J.vdWolde@wegener.nl>,   \"Debbie Derksen\"  <deberken@casema.nl>,   corine  <corine5@xs4all.nl>, \"Markies Aart\" <A.Markies@wegenernieuwsmedia.nl>";

    // Split up into each person's details
    String[] nameEmailPairs = test.split(",\\s*(?=\")");
    for (String nameEmailPair : nameEmailPairs) {
        // Extract exactly the parts you need from the person's details
        String name = nameEmailPair.replaceAll("\"([^\"]+)\".*", "$1");
        String email = nameEmailPair.replaceAll(".*<([^>]+).*", "$1");
        System.out.println(name + " = " + email);
    }
}

输出，显示它确实有效:)

Talboom, Esther = E.Talboom@wegener.nl
Wolde, Jos van der = J.vdWolde@wegener.nl
Debbie Derksen = corine5@xs4all.nl
Markies Aart = A.Markies@wegenernieuwsmedia.nl
