    <p>Here's a fragile attempt to use regular regular expressions and recursion: </p> <pre><code>static class Program { static void Main(string[] args) { string prefix = "&gt;"; string suffix = "&gt;"; string subject = "Subject&gt;memberName1&gt;memberName2&gt;member&gt;Name3&gt;EndSubject"; var result = Find(subject, true, prefix, suffix).ToList(); result.ForEach(item =&gt; { Console.WriteLine(item); }); /* The output is: memberName1&gt;memberName2 member&gt;Name3 *match memberName1 *match memberName2 *match member Name3 */ } private static IEnumerable&lt;string&gt; Find( string subject, bool toggle, string prefix, string suffix) { string r1 = @"(?&lt;=" + prefix + @")(?&gt;([\w]*(" + prefix + "|" + suffix + @")[\w]*))(?=" + suffix + ")", r2 = @"[\w]*"; var temp = Regex.Matches(subject, toggle ? r1 : r2 ) .Cast&lt;Match&gt;() .ToList(); return temp.SelectMany(m =&gt; temp .Select(i =&gt; i.Value) .Union(Find(m.Value, !toggle, prefix, suffix))) .Where(s =&gt; !String.IsNullOrEmpty(s)) .Distinct(); } } </code></pre> <p><em>Note: I'm not sure if in your example, the <code>&gt;</code> in <code>member&gt;Name3</code> is considered a prefix or a suffix.</em></p> <p>[EDIT] Here's another approach, which doesn't use regular expressions. It takes into account that the <code>&gt;</code> in the <code>member&gt;Name3</code> could be a prefix <strong>or</strong> a suffix:</p> <pre><code>var separators = new[] { prefix, suffix }; var firstResult = separators .SelectMany(s =&gt; subject .Split(separators,StringSplitOptions.RemoveEmptyEntries) .Skip(1) .Reverse() .Skip(1) .Reverse()) .Distinct() .ToList(); var result = firstResult .Zip(firstResult.Skip(1), (a, b) =&gt; { var l = new List&lt;string&gt;(); separators.ToList().ForEach(s =&gt; { l.Add(String.Format("{0}{1}{2}", a, s, b)); }); return l; }) .SelectMany(s =&gt; s) .Union(firstResult) .ToList(); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
