java - 如果输入有时没有标记，则对数组中的多个字符串进行标记

Question

我已在此表单中输入内容

<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="95e1f0e6e1d5e1f0e6e1bbf6faf8" rel="noreferrer noopener nofollow">[email protected]</a>

和\或以这种形式

<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b8ccddcbccf8ccddcbcc96dbd7d5" rel="noreferrer noopener nofollow">[email protected]</a>;<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="32465741460072465741461c515d5f" rel="noreferrer noopener nofollow">[email protected]</a>

或

<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="344051474074405147401a575b59" rel="noreferrer noopener nofollow">[email protected]</a>;<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="64100117105624100117104a070b09" rel="noreferrer noopener nofollow">[email protected]</a>;<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a2d6c7d1d691e2d6c7d1d68cc1cdcf" rel="noreferrer noopener nofollow">[email protected]</a>

我应该在一个字符串数组中标记所有内容，其中每个单元格仅包含一封电子邮件，没有任何分隔符

您不想标记化，只需使用split:

String[] emails = { "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="572332242317233224237934383a" rel="noreferrer noopener nofollow">[email protected]</a>;<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="56223325226416223325227835393b" rel="noreferrer noopener nofollow">[email protected]</a>;<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="0a7e6f797e394a7e6f797e24696567" rel="noreferrer noopener nofollow">[email protected]</a>", "<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="abdfced8dfebdfced8df85c8c4c6" rel="noreferrer noopener nofollow">[email protected]</a>"  };
List<string> result = new ArrayList<String>();

for ( string listOfEmails : emails ) {
  for( string email : listOfEmails.split(";") ) {
    result.Add(email).
  }
}

System.out.println(result);

它适用于所有情况。
