C#: How to find tags with regex and collect a List<string>

I have a text string like this:

<dt>
  <span>
    <tag:text name="fee" />
  </span>
</dt>
...
<tag:text name="amount" />    

what I want is to find all tags of type

<tag:text 

and then collect a List with the values fro开发者_如何学Cm the name element:

"fee"
"amount"

---

(?<=tag:text name=").*(?=") 

test with grep:

kent$  echo '<dt>
      <span>
        <tag:text name="fee" />
      </span>
    </dt>
    ...
    <tag:text name="amount" />   '|grep -Po '(?<=tag:text name=").*(?=")' 

    fee
    amount

Here's the regex you (EDIT: probably don't) want, just make sure to turn off case sensitivity:

<([A-Z][A-Z0-9]*)\b[^>]*>(.*?)</\1>

Then just use the System.Text.RegularExpressions.Regex class to perform the regex operation:

MatchCollection mc = Regex.Matches(str, @"<([A-Z][A-Z0-9]*)\b[^>]*>(.*?)</\1>", RegexOptions.IgnoreCase);

See here for more info: http://msdn.microsoft.com/en-us/library/b49yw9s8.aspx

Note: You may need to tweak the regex to work with the colons in your text.

Note #2: As mentioned above, if this is XML then you should parse it using the appropriate XML classes from the System.Xml namespace.
