Example

The following code illustrates how to find and parse dates in US format using Regular Expression pattern matching:

document.AppendText("12\\14\\2014" + Environment.NewLine);
IRegexSearchResult result;
string pattern = @"(?<mm>\d{2}).(?<dd>\d{2}).(?<yyyy>\d{4})";
System.Text.RegularExpressions.Regex myRegEx = 
    new System.Text.RegularExpressions.Regex(pattern);

result = document.StartSearch(myRegEx);
if (result.FindNext())
{
    string dayFound = result.Match.Groups[2].Value;
    string monthFound = result.Match.Groups[1].Value;
    string yearFound = result.Match.Groups[3].Value;
    document.AppendText(String.Format("Found a date that is the {0} day of the {1} month of the {2} year.",
        dayFound, monthFound, yearFound));
}
