    <p>It's possible with regex but LINQ to XML is simpler. I've included LINQ to XML and a regex solution, although I would favor the former.</p> <p>Here's the LINQ to XML approach. Since <code>ul</code> is the top element its <code>Name</code> can be changed directly. <code>Descendants</code> will grab all the nested <code>ul</code> items. The only caveat with this approach is it only works if the input is well-formed. If it's wrong LINQ to XML will fail to parse it. Also, if it is well-formed and the <code>ul</code> isn't the top element but is part of a larger HTML block of text then you'll need to loop over <code>Elements("ul")</code> then do the same thing over each of them.</p> <p>If the HTML is malformed you may want to look at the <a href="http://htmlagilitypack.codeplex.com/" rel="nofollow noreferrer">HTML Agility Pack</a>.</p> <pre><code>Dim xml = XElement.Parse(input) xml.Name = "textformat" xml.SetAttributeValue("indent", "0") For Each item In xml.Descendants("ul") item.Name = "textformat" item.SetAttributeValue("indent", "20") Next </code></pre> <p>And here's the regex approach. It's not easy to detect the first <code>ul</code> item to distinguish between the two so this approach changes all of them to an indent of 20, then an extra step is taken to find the first <code>textformat</code> and change its indent to zero.</p> <pre><code>Dim pattern As String = "&lt;ul&gt;|&lt;/ul&gt;" Dim result As String = Regex.Replace(input, pattern, Function(m) If(m.Value.StartsWith("&lt;/"), "&lt;/textformat&gt;", "&lt;textformat indent=""20""&gt;")) Dim firstTextFormatPattern As String = "^(?&lt;Start&gt;&lt;textformat\s+indent="")\d+?(?&lt;End&gt;""&gt;)" result = Regex.Replace(result, firstTextFormatPattern, "${Start}0${End}") </code></pre>

    1. COThanks again for you help. I am looking into the HTML Agility Pack for the LINQ solution as this is throwing a lot of exceptions (my flashed based HTML can often appear malformed). With your regex solution the final replace statement doesn't appear to be working, the first textformat tag isn't changing to have an indent attribute set to zero. Also with both solutions will they cope with mutiple ULs in the same string? (specifically converting the first tags indent attribute) By this I mean if they retrieved a string with my example above twice, I hope that makes sense....

    2. CO@chapmanio the last pattern assumes the input was the beginning of the string. If it occurred at any location within a larger string it wouldn't work. To answer your other question the first regex pattern will affect all occurrences in the string. LINQ to XML would need to be tweaked to get all `Elements("ul")` to find all `ul` elements at the root level. Then `foreach` over them and get their `Descendants` and carry on as shown in my example. How the entire string looks like would make a difference. Glad you found a solution to your problem.

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.
