I have following CDATA inside xml document:

<![CDATA[ <p xmlns="">Refer to the below: <br/>
</p>
<table xmlns:abc="http://google.com pic.xsd" cellspacing="1" class="c" type="custom" width="100%">
    <tbody>
        <tr xmlns="">            
            <th style="text-align: left">Basic offers...</th>
        </tr>
        <tr xmlns="">
            <td style="text-align: left">Faster network</td>
            <td style="text-align: left">
            <ul>                
                <li>Session</li>
            </ul>
            </td>
        </tr>
        <tr xmlns="">
            <td style="text-align: left">capabilities</td>
            <td style="text-align: left">
            <ul>                
                <li>Navigation,</li>
                <li>message, and</li>
                <li>contacts</li>
            </ul>
            </td>
        </tr>
        <tr xmlns="">
            <td style="text-align: left">Data</td>
            <td style="text-align: left">
            <p>Here visit google for more info <a href="http://www.google.com" target="_blank"><font color="#0033cc">www.google.com</font></a>.</p>
            <p>Remove this href tag <a href="/abc/def/{T}/t/1" target="_blank">Information</a> remove the tag.</p>
            </td>
        </tr>
    </tbody>
</table>
<p xmlns=""><br/>
</p>
  ]]> 

I want to some how scan for href=”/abc/def and remove the href tag which starts with abc/def. In above example remove the href tag and just leave “Information” text inside the tag. CDATA can have more than one href tags with “abc/def… in it.
I am using C# for this application. Can someone please help me and tell me how this can be done? Should i use regex or is there a way to do it with xml itself?

This is the regex i am trying:

"<a href=\"/abc/def/.*></a>"

I want to keep inner text of the a href tag just remove the tags. But above regex is not working.

Using HtmlAgilityPack

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);

var nodes = doc.DocumentNode
    .Descendants("a")
    .Where(n => n.Attributes.Any(a => a.Name == "href" && a.Value.StartsWith("/abc/def")))
    .ToArray();

foreach(var node in nodes)
{
    node.ParentNode.RemoveChild(node,true);
}

var newHtml = doc.DocumentNode.InnerHtml;
