Asp.net - Remove Xml Tags But Leave Its Name .net Jquery?

I have a xml like this:

<?xml version="1.0" encoding="utf-8"?>
<xs:PersonaRCV xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:Identificacion>201232934</xs:Identificacion>

[code]....

and i called it in my aspx like this:

<pre><asp:Label ID="LBXML" runat="server"><%# Server.HtmlEncode(FormatXml(Eval("Respuesta")))%></asp:Label></pre>

Finally the code seen with Firebug looks like this:

&lt;xs:PersonaRCV xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema"&gt;
&lt;xs:Identificacion&gt;401690010&lt;/xs:Identificacion&gt;
&lt;xs:Nombre&gt;MAX FRANCISCO&lt;/xs:Nombre&gt;

I was trying to do something with jquery replace:

var queHay = $("#MostrarEsconder" + myVal + " span").html();
queHay.replace('/&lt;xs:/', '');

but i can't get it to work.Anyone can suggest something to get my results as i want them? with jquery or in codebehind in my FormatXML function!
