Strip off the base64 content from an XML and saving the rest in streaming fashion using XML Reader Class.

Question

Hi,
I'm presently working in a scenario, where i need to read an XML (having base64 encoded images) using XmlReader class in a streaming fashion (considering the performance) .
1) I have to strip offs the base64 encoded contents from the xml (front & back image node).
2) Than saving the remaining XML (without base64 content) . 
Sample XML:-
<?xml version="1.0" encoding="utf-8"?>
<tran>
  <tranheader>
 <feild1></feild1>
  </tranheader>
  <item>
<fields></fields>
    <image>
      <frontimage>base64_content</frontimage>
      <rearimage>base64_content</rearimage>
    </image>
  </item>
  <item>
    <fields></fields>
    <image>
      <frontimage>base64_content</frontimage>
      <rearimage>base64_content</rearimage>
    </image>
  </item>
  <trantrailer>
    <feild1></feild1>
  </trantrailer>
</tran>
Please guide.
Thanks & Regards

E.g. a simplified skeleton:
namespace ConsoleCS
using System;
using System.IO;
using System.Xml;
using System.Xml.Linq;
class Program
static void Main(string[] args)
XDocument xdocument = XDocument.Parse(@"
<Items>
<Item>Test with a child element <more/> stuff</Item>
<Item>Test with a CDATA section <![CDATA[<456>]]> def</Item>
<Item>Test with a char entity: &#65;</Item>
<SkipItem>Item to skip.</SkipItem>
<!-- Fourteen chars in this element.-->
<Item>1234567890ABCD</Item>
</Items>");
StringReader stringReader = new StringReader(xdocument.ToString());
XmlReader xmlReader = XmlReader.Create(stringReader);
xmlReader.MoveToContent();
while (xmlReader.Read())
switch (xmlReader.NodeType)
case XmlNodeType.Element:
if (xmlReader.Name == "SkipItem")
Console.WriteLine("Skipping..");
else
Console.WriteLine("Pushing to output ({0}).", xmlReader.Name);
break;
Console.WriteLine("Done.");
Console.ReadLine();
