帮忙写个获取IP地址的正则表达式，谢谢

<TD align=middle bordercolordark="#000000" width="113" height="14"><div id=ip0><A title="点击复制此IP地址" onClick="copycode(findobj('ip0'));"><font color=black>200.30.101.20</font></a></div></TD>
    <TD align=middle bordercolordark="#000000" width="56" height="14"><div id=port0><A title="点击复制此端口" onClick="copycode2(findobj('port0'));"><font color=black>8080</font></a></div></TD>
    <TD align=middle bordercolordark="#000000" width="60" height="14">正常</TD>
    <TD align=middle bordercolordark="#000000" width="62" height="14">4608</TD>

需要得到的是：200.30.101.20:8080 --------------------编程问答--------------------

@"(?s)'ip0'.*?(?<ip0>[\d.]+).*?'port0'.*?(?<port0>\d+)"
