我有一段文字

THE ABOVE REFERENCED CUSTOMER HAS ELECTED TO ROLLOVER THE 60,000,000.00 US DOLLARS LIBOR RATE LOAN MATURING 04/13/07, YOUR SHARE 342,857.14.

我定义的关键字是 ELECTED TO ROLLOVER THE 和 LOAN MATURING 和 YOUR SHARE

我想要得正则表达式实现这样

ELECTED TO ROLLOVER THE 60,000,000.00 US DOLLARS LIBOR RATE

LOAN MATURING 04/13/07,

YOUR SHARE 342,857.14.

也就是按照定义的关键字加空格来进行匹配

请问怎样实现这个正则表达式呢？？

谢谢大家了！

using System.Text.RegularExpressions;

Regex re = new Regex(@"(ELECTED.*\s(\d{1,3},?)*.\d*.*RATE).*(LOAN.*/\d{2,4}).*(YOUR.*\s(\d{1,3},?)*.\d*)");

Match m = re.Match("your string");
if( m.Success )
{
Response.Write(m.Groups[1].Value + " ");
Response.Write(m.Groups[3].Value + " ");
Response.Write(m.Groups[4].Value + " ");}
else

try

string yourStr = ............;
Match m = Regex.Match(test, @"((date.*?)(to.*?))?(re.*?)?(effective.*?)?((borrower's commitment will be reduced from.*?)(to.*?))?((Your share of the commitment will be reduced from.*?)(to.*?))?$", RegexOptions.IgnoreCase);

Response.Write(m.Groups[5].Value + " ");
Response.Write(m.Groups[7].Value + " ");
Response.Write(m.Groups[8].Value + " ");
Response.Write(m.Groups[10].Value + " ");
Response.Write(m.Groups[11].Value + " ");

1 Date
2 Tｏ 1
3 Re 2
4 Effective
5 borrower's commitment will be reduced from
6 to 5
7 Your share of the commitment will be reduced from
8 to 7

谢谢你，再帮帮我好吗例如上面这个表
第一列是顺序列第２列是关键字列第３列标示了当前的关键字在第几个关键字之后例如
第一个关键字是Ｄａｔｅ第２个关键字是ＴｏＴｏ后面的１代表在第１个关键字之后；
依次类推:5 borrower's commitment will be reduced from
to后面的的5代表在第5个关键字之后

请问我要象匹配这样的要怎么写呢

那关键字的前后顺序是否固定呢？

另外就是
borrower's commitment will be reduced from
to
以及
Fax：
to
应该是配对出现的吧

如果这样，试下

string yourStr = .............;
string test = "Effective 30-Mar-2007, Fax 098-245-8787 to USD 98,230,000.00.";
Match m = Regex.Match(test, @"(Effective.*?)?((the borrower's commitment will be reduced from.*?)(to.*?))?((Fax.*?)(to.*))?$", RegexOptions.IgnoreCase);
if (m.Success)
{
Response.Write(m.Groups[1].Value + " ");
Response.Write(m.Groups[3].Value + " ");
Response.Write(m.Groups[4].Value + " ");
Response.Write(m.Groups[6].Value + " ");
Response.Write(m.Groups[7].Value + " ");
}

如果某一个值没空，那就是说明不存在这个关键字，至于结果如何处理，你自己看下吧

可是，我定义的关键字是不定的，有可能是２个３个４个或者多个．
那我的正则表达式要怎么匹配呢

谢谢了强人

其实这里真的没必要用正则的...

string test = "Effective 30-Mar-2007, the borrower's commitment will be reduced from USD 144,725,000.00 to USD 144,450,000.00. Fax 098-245-8787 to USD 98,230,000.00.";
Match m = Regex.Match(test, @"(Effective.*?)(the borrower's commitment will be reduced from.*?)(to.*?)(Fax.*?)(to.*)", RegexOptions.IgnoreCase);
if (m.Success)
{
Response.Write(m.Groups[1].Value + " ");
Response.Write(m.Groups[2].Value + " ");
Response.Write(m.Groups[2].Value + " ");
Response.Write(m.Groups[3].Value + " ");
Response.Write(m.Groups[4].Value + " ");
Response.Write(m.Groups[5].Value + " ");
}

哦是这样子的
例如这样:
Effective 30-Mar-2007, the borrower's commitment will be reduced from USD 144,725,000.00 to USD 144,450,000.00. Fax 098-245-8787 to USD 98,230,000.00.

关键字是：Effective
borrower's commitment will be reduced from
to
Fax：
to
也就是说一行中有多个定义的关键字我该怎么匹配呢

谢谢，能给个正则表达式吗

不知道是不是我理解错误，既然ELECTED TO ROLLOVER THE 和 LOAN MATURING 和 YOUR SHARE 这些关键词固定了，为什么不用IndexOf来取呢

以下为正则实现方式

string test = "THE ABOVE REFERENCED CUSTOMER HAS ELECTED TO ROLLOVER THE 60,000,000.00 US DOLLARS LIBOR RATE LOAN MATURING 04/13/07, YOUR SHARE 342,857.14.";
Match m = Regex.Match(test, @"(ELECTED TO ROLLOVER THE.*?)\s*(LOAN MATURING.*?)\s*(YOUR SHARE.*)$", RegexOptions.IgnoreCase);
if(m.Success)
{
Response.Write(m.Groups[1].Value + " ");
Response.Write(m.Groups[2].Value + " ");
Response.Write(m.Groups[3].Value + " ");
}

Regex re = new Regex(@"(?<name>((ELECTED TO ROLLOVER THE)|(LOAN MATURING)|(YOUR SHARE)))(?<value>.*?)((?=ELECTED TO ROLLOVER THE)|(?=LOAN MATURING)|(?=YOUR SHARE)|$)");
MatchCollection mc = re.Matches(str);
foreach (Match m in mc)
{
MessageBox.Show(m.Groups["name"].ToString() + ":" + m.Groups["value"].ToString());
}
