如何从Android / Java中的字符串中获取多个子字符串？

String str = "What is <Mytag a exp 5 exp 3> written as a single power of <i>a</i> <Mytag yx4> and the double power of <b>x+y</b> <Mytag 3xy4>";

我想在“< Mytag”和“>”之间获得子串

所以我的愿望输出将是
1)exp 5 exp 3
2)yx4
3)3xy4

我已经尝试使用Scanner并对我获得第一个字符串成功的所有内容进行子串,但是第二次和第三次出现的问题.

在子字符串方法中,我成功获得所有tages“< Mytag”的索引,但无法获得正确的索引“>”因为它也带有粗体和斜体.

// import java.io.Console;
import java.util.regex.Pattern;
import java.util.regex.Matcher;

public class RegexTestHarness {

  public static void main(String[] args){
    // Console console = System.console();  // Not needed

    Pattern pattern = Pattern.compile("<Mytag([^>]*)>");

    String myString = "What is <Mytag a exp 5 exp 3> written as a single power of <i>a</i> <Mytag yx4> and the double power of <b>x+y</b> <Mytag 3xy4>";
    Matcher matcher = pattern.matcher(myString);

    while (matcher.find()) {
      // Rohit Jain observation
      System.out.println(matcher.group(1));
    }

  }
}
