    <p>I am not very well-versed in regular expressions, but I am trying to accomplish something in ASP.Net which I think requires them.</p> <p>I am pulling in an HTML file, doing some processing, and outputting new "merged" html. The portion I am struggling with is grabbing a chunk of code located between two predefined "tags" of my own creation.</p> <p>Here is an example of the relevant input html:</p> <pre><code>&lt;table style="width: 500px; font-family: Trebuchet MS, sans-serif; font-size: 13px; background-color: #fff; border: 0; border-collapse: collapse;" align="center" cellspacing="0"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th colspan="3" style="text-align: left;border-bottom: 1px solid #DDDDDD;"&gt; Add-ons &lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; [AddonsListSTART] &lt;tr style="border-bottom: 1px dashed #DDDDDD;"&gt; &lt;td&gt;[AddonName]&lt;/td&gt; &lt;td&gt;[AddonQty]&lt;/td&gt; &lt;td align="right"&gt;[AddOnPrice]&lt;/td&gt; &lt;/tr&gt; [AddonsListEND] &lt;/tbody&gt; &lt;/table&gt; &lt;br /&gt; </code></pre> <p>This is my C# code:</p> <pre><code>//Find Add-ons HTML : between [AddonsListSTART] &amp; [AddonsListEND] Regex rgxAddonSE = new Regex(@"\[AddonsListSTART\](?&lt;MyHtml&gt;.*)\[AddonsListEND\]"); Match matchAddonSE = rgxAddonSE.Match(htmlEmail); string htmlAddons = matchAddonSE.ToString(); </code></pre> <p>What I want to happen is for "htmlAddons" to be equal to the string:</p> <pre><code>&lt;tr style="border-bottom: 1px dashed #DDDDDD;"&gt; &lt;td&gt;[AddonName]&lt;/td&gt; &lt;td&gt;[AddonQty]&lt;/td&gt; &lt;td align="right"&gt;[AddOnPrice]&lt;/td&gt; &lt;/tr&gt; </code></pre> <p>The problem is that it is always blank, and "matchAddonSE.Success" is always FALSE. I know there is something wrong with my regex, but I can't figure out what.</p> <p>Thank you in advance for any help.</p> <p>Heather</p>

    1. COAha! A helpful link displayed in the sidebar lead me to the answer: http://stackoverflow.com/questions/4000508/regex-expression-that-will-capture-everything-between-two-characters-including-m - this regex now works: `new Regex(@"\[AddonsListSTART\](?<MyHtml>[\s\S]*)\[AddonsListEND\]")`

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
