返回源字符串中匹配的结束位置。捕获组的结束位置可以通过提供其组号的整数或其字符串名称（如果它是一个命名组）来检索。默认值为 0，指的是整个表达式。
|
||
|
||
如果该组没有匹配或不存在，则返回 -1。

|
||
|
||
返回源字符串中匹配的起始位置。捕获组的起始位置可以通过提供它的组号作为一个整数或它的字符串名称（如果它是一个命名组）来检索。默认值为 0，指的是整个表达式。
|
||
|
||
如果组没有匹配或不存在，返回 -1。

|
||
|
||
返回源字符串中匹配的子串。捕获组可以通过提供它的组号作为整数或它的字符串名称（如果它是一个命名组）来检索。默认值为 0，指的是整个表达式。
|
||
|
