!!!!!!!!!!!!!!!!!!!!!!!!!求一个正则表达式

[约修亚]

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！

string str = "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.";
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());
}

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 + "<br>");
Response.Write(m.Groups[2].Value + "<br>");
Response.Write(m.Groups[3].Value + "<br>");
}

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 [phone] 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

[-过客-]

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 [phone] 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 + "<br>");
Response.Write(m.Groups[2].Value + "<br>");
Response.Write(m.Groups[2].Value + "<br>");
Response.Write(m.Groups[3].Value + "<br>");
Response.Write(m.Groups[4].Value + "<br>");
Response.Write(m.Groups[5].Value + "<br>");
}

[约修亚]

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

[-过客-]

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 [phone] 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 + "<br>");
Response.Write(m.Groups[3].Value + "<br>");
Response.Write(m.Groups[4].Value + "<br>");
Response.Write(m.Groups[6].Value + "<br>");
Response.Write(m.Groups[7].Value + "<br>");
}

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

强人，学习对象

[约修亚]

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 Ｔｏ Ｔｏ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

[-过客-]

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);
if (m.Success)
{
Response.Write(m.Groups[2].Value + "<br>");
Response.Write(m.Groups[3].Value + "<br>");
Response.Write(m.Groups[4].Value + "<br>");
Response.Write(m.Groups[5].Value + "<br>");
Response.Write(m.Groups[7].Value + "<br>");
Response.Write(m.Groups[8].Value + "<br>");
Response.Write(m.Groups[10].Value + "<br>");
Response.Write(m.Groups[11].Value + "<br>");
}

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