title: Remove a node from the following XML.
body: <p>This is the xml I got as an output from the <code>WriteXmlString()</code> of <code>Infragistics ultrawebtree</code>. I am using this to create another <code>Infragistics ultrawebtree</code> with the same structure. But here I don't want the <code>&lt;Url&gt;something.aspx..&lt;/Url&gt;</code>. I want that to be like this <code>&lt;Url&gt;&lt;\Url&gt;</code>. So how I can able to remove. This I get as a String. So I used <code>Regex.Replace()</code>. But it will work for certain conditions,but for some case it will destruct the xml by deleting some xml tags and xml became not valid due to missing of tags.
  I used this expression <code>&lt;Url&gt;\S*&lt;/Url&gt;</code> to avoid the contents of Url.  Any help will be very helpful. Thanks in advance.</p>
