How to avoid namespace coming in output XML in XSLT

I am working on XML to XML transformations through XSLT. I want to remove the name spaces in output xml. For that I have used Exclude result prefix option, but in the output i still see the namespaces.

Sorce XML:

 <?xml version="1.0" encoding="ISO-8859-1"?>
 <aaa>
 hello
 </aaa>

XSLT written:

 <?xml version="1.0" encoding="utf-8"?>
 <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"      xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:simple="aaaa" xmlns:xlink="http://www.w3.org/1999/xlink"      xmlns:tcm="http://www.tridion.com/ContentManager/5.0" exclude-result-prefixes="msxsl simple wireframe widget tcdl tcm xlink"      xmlns:wireframe="bbb" xmlns:widget="ccc" xmlns:tcdl="tcdl">
  <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" />
 <xsl:template match="/">
  <wireframe:wireframe>
       <wireframe:si>
         <widget:ah>
         <xsl:value-of select="aaa" />
               </widget:ah> 
         </wireframe:si>
 </wireframe:wireframe>
 </xsl:template>
   </xsl:stylesheet>

OUTPUT produced:

 <?xml version="1.0" encoding="utf-8"?>
 <wireframe:wireframe xmlns:wireframe="aaaa">
   <wireframe:si>
     <widget:ah xmlns:widget="bbb">
 hello
 </widget:ah>
   </wireframe:si>
 </wireframe:wireframe>

Output Expexcted:

 <?xml version="1.0" encoding="utf-8"?>
 <wireframe:wireframe>
   <wireframe:si>
     <widget:ah>
 hello
 </widget:ah>
   </wireframe:si>
 </wireframe:wireframe>

Please tell me how to avoid namespace appearance in output XML.

Thank you in advance.

Solution

You could leave out the two used namespaces in the exclude attribute as follows:

exclude-result-prefixes="msxsl simple xlink tcm tcdl"

which will make sure that the two namespaces which are used appear in the root element, not in the element where they are first used; the result will be:

<?xml version="1.0" encoding="UTF-8"?>
<wireframe:wireframe xmlns:widget="ccc" xmlns:wireframe="bbb">
    <wireframe:si>
        <widget:ah>
 hello
 </widget:ah>
    </wireframe:si>
</wireframe:wireframe>
