请问提取网页内容(如下)的正则表达式
网页源码:

网页格式:
游戏区域 目前价格 收购量 状态 操作
Aegwynn US-Alliance 0.88 元/ Gold 0 满仓
Aegwynn US-Horde 0.94 元/ Gold 0 满仓
Aerie 'peak US-Alliance 0.94 元/ Gold 0 满仓
Aerie 'peak US-Horde 0.99 元/ Gold 0 满仓
Agamaggan US-Alliance 0.82 元/ Gold 0 满仓
请问提取:游戏区域 ,目前价格 ,收购量 ,状态 的正则表达式.
[解决办法]
太长了，就采取了点偷懒的办法，假定格式都是这样的，楼主试下吧，如果有不符合的，我再看看吧
string yourStr = richTextBox1.Text;
MatchCollection mc = Regex.Matches(yourStr, @ " <table[^> ]*?> \s+ <tr[^> ]*?> \s+ <td[^> ]*?> (? <area> [^ <]*?) </td> \s+ <td[^> ]*?> (? <price> [^ <]*?) </td> \s+ <td[^> ]*?> <font[^> ]*?> (? <num> [^ <]*?) </font> </td> \s+ <td[^> ]*?> <font[^> ]*?> (? <state> [^ <]*?) </font> </td> ", RegexOptions.IgnoreCase);
foreach (Match m in mc)
{
richTextBox2.Text += m.Groups[ "area "].Value + "\n "; //游戏区域
richTextBox2.Text += m.Groups[ "price "].Value + "\n "; //目前价格
richTextBox2.Text += m.Groups[ "num "].Value + "\n "; //收购量
richTextBox2.Text += m.Groups[ "state "].Value + "\n "; //状态
}
