Can someone please help me with RegEx?

assuming I have template HTML file which contains property names to evaluate
at run time

<HTML>
<BODY><%PropertyName1%>
<DIV ID="<%PropertyName2%>">
</HTML>


How do I find all matches for <%...%> ,i dont know which pattern to use.

string pattern="";

string input=".....";



Regex rex = new Regex(pattern, RegexOptions.IgnoreCase);

for (Match match = rex.Match(input);match.Success;match = match.NextMatch())

{

Console.WriteLine("Found '{0}' at position {1}",match.Value, match.Index);

}


Thanks in advance

First of all, life becomes much easier, if you use a one-character token
to introduce the property name, so how 'bout we change this to:

<HTML>
<BODY>{PropertyName1}
<DIV ID="{PropertyName2}">
</HTML>

(You weren't planning on using braces {} in your HTML for anything else,
right?


So then you want to find an opening brace {, followed by a number of
characters * which can be anything except a closing brace [^}], immediately
followed by a close brace:
{[^}]*}

Next, we want to capture the name of the property, so we wrap that part of
parens:
{([^}]*)}

Finally, { & } mean something special to the regex parser, so we have to
escape them:

\{([^\}]*)\}
