Removing a section of HTML from an EmailMessage Body in EWS

Is there a way to remove certain parts of the EWS EmailMessage .Body.Text value in C# before replying with a ResponseMessage?

The elements that need to be removed include clickable and non-clickable buttons in HTML format.

Since custom tags cannot be declared, using string.replace to locate these custom html tags is not an option. Are there alternative methods I can explore, like placing the content in a placeholder?

<table class="MsoNormalTable" border="0" cellspacing="0" cellpadding="0" width="100%" style="width:100.0%">
<tbody>
<tr>
<td style="padding:0in 0in 0in 0in">
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:&quot;Times New Roman&quot;,serif">&nbsp;<o:p></o:p></span></p>
</td>
<td width="30%" style="width:30.0%;background:#17202A;padding:4.5pt 4.5pt 4.5pt 4.5pt;display:inline-block">

Answer №2

If you need to delete the table that contains the Multiply and Divide buttons and they are not present anywhere else in the document, you can use XPath along with those elements to locate and eliminate the table. While you could potentially utilize the built-in XMLDocument class, I suggest using HTMLAgilityPack (which is available as a nuget package) for parsing HTML.

Here's an example of how it might look:

//Create a HTMLAgilityPack Document
HtmlDocument doc = new HtmlDocument();
//Load the email body
doc.LoadHtml(EmailMessage.Body.Text);
//Select the ancestor table of the link we're interested in
HtmlNode node = doc.DocumentNode.SelectSingleNode("//a[@href='mailto:test.com?subject=[DIVIDE];body=ACTION:%20DIVIDE']//ancestor::table");
//Remove the table
node.Remove();

//Get the new email body
string newBody = doc.DocumentNode.InnerHtml;

You may need to make some adjustments to suit your needs, but this should give you a solid starting point.
