    <p>I've converted a large document from Word to HTML. It's close, but I have a bunch of "code" nodes that I'd like to merge into one "pre" node.</p> <p>Here's the input:</p> <pre><code>&lt;p&gt;Here's a sample MVC Controller action:&lt;/p&gt; &lt;code&gt; public ActionResult Index()&lt;/code&gt; &lt;code&gt; {&lt;/code&gt; &lt;code&gt; return View();&lt;/code&gt; &lt;code&gt; }&lt;/code&gt; &lt;p&gt;We'll start by making the following changes...&lt;/p&gt; </code></pre> <p>I want to turn it into this, instead:</p> <pre><code>&lt;p&gt;Here's a sample MVC Controller action:&lt;/p&gt; &lt;pre class="brush: csharp"&gt; public ActionResult Index() { return View(); }&lt;/pre&gt; &lt;p&gt;We'll start by making the following changes...&lt;/p&gt; </code></pre> <p>I ended up writing a brute-force loop that iterates nodes looking for consecutive ones, but this seems ugly to me:</p> <pre><code>HtmlDocument doc = new HtmlDocument(); doc.Load(file); var nodes = doc.DocumentNode.ChildNodes; string contents = string.Empty; foreach (HtmlNode node in nodes) { if (node.Name == "code") { contents += node.InnerText + Environment.NewLine; if (node.NextSibling.Name != "code" &amp;&amp; !(node.NextSibling.Name == "#text" &amp;&amp; node.NextSibling.NextSibling.Name == "code") ) { node.Name = "pre"; node.Attributes.RemoveAll(); node.SetAttributeValue("class", "brush: csharp"); node.InnerHtml = contents; contents = string.Empty; } } } nodes = doc.DocumentNode.SelectNodes(@"//code"); foreach (var node in nodes) { node.Remove(); } </code></pre> <p>Normally I'd remove the nodes in the first loop, but that doesn't work during iteration since you can't change the collection as you iterate over it.</p> <p>Better ideas?</p>

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.
