Prefix not Bound to a namespace Error with XML parser

[Nihar Khan]

Hello Programming gurus,

when i was downloading a trial version of Dreamweaver CS4 which was downloaded from the adobe website and once i try installing it it comes up with 'please delete current menus.xml file and then rename menus.bak file to menus.xml'. Once I tried that the new renamed xml file has the same problem as the old one. Now, When i opened up the file in Firefox it came up with an XML Parsing error, which is how I came to this forum. The exact error is as below:

Prefix not Bound to a namespace

What does this problem suggest and how to get rid of this...

Have you tried removing the line break after ?

You could just remove all \n's from the code that generates those tags and it should help...

The message you are getting is caused by missing namespace declarations.

This code would reproduce the message:

 <xmp b:backbase="true">
   <foobar:node>...</foobar:node>
 </xmp>

This would fix it:

<!-- just make up your own namespace URI -->
 <xmp b:backbase="true" xmlns:foobar="http://foobar.com/foobar">
  <foobar:node>...</foobar:node>
</xmp>

If you find that this problem occurs during the Adobe installation then reinstall that application and whether that same problem appears...Reinstallation may eliminate this problem.
