Hi All,
I have the following structure in my XML and i need to translate the following object into

Input content
<?xml version="1.0" encoding="UTF-8"?>
   <content name="subject"><html>Hello [[BUYERS_NAME]]</html>
</content><!--BASE 64 encoded-->
   <content name="text">Hello [[BUYERS_NAME]]</content><!--

<!--Line Items-->

<?xml version="1.0" encoding="UTF-8"?> <htmlbody> <html>Hello Senthil </html> </htmlbody> <htmlbody> <textbody> Hello Senthil </textbody >

Could you please help me in decoding the base64 encode and replace the variable with the associated enclosed content.
I have gone through Mukul website and I am still strugging for the decoding of BASE64 content and replace the [[]]
content with the value in it.

Any eye opener suggestion are welcome.

Thanks in advance.
