How could i parse below text identifying xml tags using regular expression.


Dear <customer>
This is to let you know that your following Tickets have been confirmed.

<Orders>

<Orders>

Total Amount is <Total>

Thanks for doing business with us.

My matches should return following
Customer
Orders
orderNo
OrderAmount
Total

The regular expression i am trying to use return only first match.

static void Main(string[] args)
        {
            //string source = "Test <TEST/>asda 9  <asdas/>";
            string source = "Test <aaa> 2323 </aaa> cvcvc <bbb>asds2323 </bbb>sas";
            //string regExp = @"(<\w+\/>)";
            //string regExp = @"(<.*<\/\w+>)+";
            string regExp = @"(<\w+>\s\w+\s<\/\w+>)+";
            Regex regx = new Regex(regExp);
            MatchCollection collection = Regex.Matches(source, regExp);
            for (int index = 0; index < collection.Count; index++)
            {
                string s = collection[index].Value;
            }
        }

推荐答案

首先简化你的正则表达式：

Start by simplifying your regex:

<.+?>

只会抓住你想要的东西。

然后，我会这样做：

Will catch just the bits you want.
Then, I'd do it like this:

        private void myButton_Click(object sender, EventArgs e)
            {
            string source = @"Dear <customer>
This is to let you know that your following Tickets have been confirmed.
 
<Orders>
<OrderNo> <OrderType> <OrderAmount>
<Orders>
 
Total Amount is <Total>

            string regExp = @"<.+?>";
            Regex regx = new Regex(regExp);
            string newData = regx.Replace(source, ReplaceData);

            }

        public string ReplaceData(Match m)
            {
            switch (m.Value)
                {
                default: return m.Value;
                case "<Orders>": return "----ORDERS DETAIL----";
                case "<OrderNo>": return "----ORDER NO----";
                ...
                }
            }

尝试一下，你会明白我的意思！
