再请教一个正则表达式！
下面的字段，怎么才能截取到Steven Liu，而不要后面的stevenliu@reemake.com呢？这个问题是面向一类字段的！
Registrant [3451728]:

  Steven Liu stevenliu@reemake.com

  Beijing Chuangrui wenhua chuangmei youxian gongsi


------解决方案--------------------
preg_match_all('#Registrant \[3451728\]:\s+(\w+\s+\w+)#s',$s,$m);
print_r($m);
