Body
The first approach: select all the <code><code></code> nodes, group them, and create a <code><pre></code> node per group: <pre><code>var idx = 0; var nodes = doc.DocumentNode .SelectNodes("//code") .GroupBy(n => new { Parent = n.ParentNode, Index = n.NextSiblingIsCode() ? idx : idx++ }); foreach (var group in nodes) { var pre = HtmlNode.CreateNode("<pre class='brush: csharp'></pre>"); pre.AppendChild(doc.CreateTextNode( string.Join(Environment.NewLine, group.Select(g => g.InnerText)) )); group.Key.Parent.InsertBefore(pre, group.First()); foreach (var code in group) code.Remove(); } </code></pre> The grouping field here is combined field of a parent node and group index which is increased when new group is found. Also I used <code>NextSiblingIsCode</code> extension method here: <pre><code>public static bool NextSiblingIsCode(this HtmlNode node) { return (node.NextSibling != null && node.NextSibling.Name == "code") || (node.NextSibling is HtmlTextNode && node.NextSibling.NextSibling != null && node.NextSibling.NextSibling.Name == "code"); } </code></pre> It used to determine whether the next sibling is a <code><code></code> node. <hr /> The second approach: select only the top <code><code></code> node of each group, then iterate through each of these nodes to find the next <code><code></code> node until the first non-<code><code></code> node. I used <code>xpath</code> here: <pre><code>var nodes = doc.DocumentNode.SelectNodes( "//code[name(preceding-sibling::*[1])!='code']" ); foreach (var node in nodes) { var pre = HtmlNode.CreateNode("<pre class='brush: csharp'></pre>"); node.ParentNode.InsertBefore(pre, node); var content = string.Empty; var next = node; do { content += next.InnerText + Environment.NewLine; var previous = next; next = next.SelectSingleNode("following-sibling::*[1][name()='code']"); previous.Remove(); } while (next != null); pre.AppendChild(doc.CreateTextNode( content.TrimEnd(Environment.NewLine.ToCharArray()) )); } </code></pre>

Guidance

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.
