    <p>My XML comes in like this:</p> <pre><code>&lt;Document type="ContentPage"&gt; &lt;Fields&gt; &lt;Field name="FaqCategory" type="dropdown" title="Select Category:" index="FaqCategory" list="\Lists\FaqCategory" required="true"&gt; Online Experience &lt;/Field&gt; &lt;Field name="FaqSubCategory" type="dropdown" title="Select Sub Category" list="\Lists\FaqSubCategory" required="true"&gt; Using the site &lt;/Field&gt; &lt;Field name="FaqQuestion" type="text" title="Enter FAQ Question:" required="true"&gt; How do I find articles on the site? &lt;/Field&gt; &lt;Field name="FaqAnswer" type="richtext" title="Enter FAQ Answer:" editorProfile="Advanced" required="true"&gt; Answer to: How do I find articles on the site? &lt;/Field&gt; &lt;/Fields&gt; &lt;Placeholders /&gt; &lt;Indexes /&gt; </code></pre> <p></p> <p>These are all in an array of XML objects, I need to sort through the array and set up (obviously) a FAQ section for this site. The problem I am having is that since this is not 1 xml document but a collection of xml documents, I am having a hard time sorting/separating by Main category > Sub category.</p> <p>Here is where I am so far with the getting of the main categories:</p> <pre><code> Protected Sub getFaqData(ByVal DocArray() As CMSWS.CMSDocumentRecord) Dim mainFaqCategoryItem As String = "" Dim mainCategoryList As New List(Of String) For Each Doc As CMSWS.CMSDocumentRecord In DocArray xml.LoadXml(Doc.Xml) Try mainFaqCategoryItem = CType(xml.SelectSingleNode("//Fields/Field[@name='FaqCategory']").InnerText, String) If Not mainCategoryList.Contains(mainFaqCategoryItem) Then mainCategoryList.Add(mainFaqCategoryItem) End If Catch ex As Exception Response.Write("ERROR getting the main category") End Try Next For Each item In mainCategoryList outputsubs(item, DocArray) Next End Sub </code></pre> <p>Here is the start of getting the sub categories and where I am stuck:</p> <pre><code> Protected Sub outputsubs(ByVal item As String, ByVal DocArray() As CMSWS.CMSDocumentRecord) Dim subFaqCategoryItem As String = "" Dim subcategoryList As New List(Of String) 'Add the main Category to the HTML output: lblFaq.Text = lblFaq.Text &amp; "&lt;h1&gt;" &amp; item &amp; "&lt;/h1&gt;" For Each Doc As CMSWS.CMSDocumentRecord In DocArray xml.LoadXml(Doc.Xml) Try 'If xml.SelectSingleNode("//Fields/Field[@name='FaqCategory']").InnerText = item Then subFaqCategoryItem = CType(xml.SelectSingleNode("//Fields/Field[@name='FaqCategory']").InnerText, String) If Not subcategoryList.Contains(subFaqCategoryItem) Then subcategoryList.Add(subFaqCategoryItem) End If 'End If Catch ex As Exception Response.Write("ERROR getting the main category") End Try Next For Each subItem In subcategoryList lblFaq.Text += "&lt;h2&gt;&lt;a name=""subCategory"" style=""text-decoration:none;""&gt;&lt;span class=""FAQPlusMinus""&gt; + &lt;/span&gt;" &amp; subItem &amp; "&lt;/a&gt;&lt;/h2&gt;" Next End Sub </code></pre> <p>My thinking is that I will need to set up for-each loops nested to about 3 levels to get this to work, but I can't get my brain around it. Especially since it isn't a single XML document. Which works to display the main categories</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.
