    <p>Lets say a have a string such as this one:</p> <pre><code>string txt = "Lore ipsum {{abc|prop1=\"asd\";prop2=\"bcd\";}} asd lore ipsum"; </code></pre> <p>The information I want to extract "abc" and pairs like ("prop1","asd") , ("prop3", "bcd") where each pair used a ; as delimeter.</p> <p><strong>Edit1: (based on MikeB's) code</strong></p> <p>Ah, getting close. I found out how to parse the following:</p> <pre><code> string txt = "Lore ipsum {{abc|prop1=\"asd\";prop2=\"http:///www.foo.com?foo=asd\";prop3=\"asd\";prop4=\"asd\";prop5=\"asd\";prop6=\"asd\";}} asd"; Regex r = new Regex("{{(?&lt;single&gt;([a-z0-9]*))\\|((?&lt;pair&gt;([a-z0-9]*=\"[a-z0-9.:/?=]*\";))*)}}", RegexOptions.Singleline | RegexOptions.IgnoreCase); Match m = r.Match(txt); if (m.Success) { Console.WriteLine(m.Groups["single"].Value); foreach (Capture cap in m.Groups["pair"].Captures) { Console.WriteLine(cap.Value); } } </code></pre> <p><strong>Question 1:</strong> How must I adjust the regex to say 'each value of a pair in delimited by \" only? I added chars like '.',';' etc, but I can't think of any char that I want to permit. The other way around would be much nicer.</p> <p><strong>Question 2</strong>: How must I adjust this regex work with this thing here?</p> <pre><code> string txt = "Lore ipsum {{abc|prop1=\"asd\";prop2=\"http:///www.foo.com?foo=asd\";prop3=\"asd\";prop4=\"asd\";prop5=\"asd\";prop6=\"asd\";}} asd lore ipsum {{aabc|prop1=\"asd\";prop2=\"http:///www.foo.com?foo=asd\";prop3=\"asd\";prop4=\"asd\";prop5=\"asd\";prop6=\"asd\";}}"; </code></pre> <p>Therefore I'd probably try to get groups of {{...}} and use the other regex?</p>

    2. COCrap indeed! That regex will match any string that contains seven letters--everything and anything else is optional. I applied it to the word "matches" and it printed the last five letters, one on each line. Fortunately, @MikeB's (edited) answer makes a lot more sense.

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.
