Android xsl transformation null pointer, but working on desktop

Question

I was working on xslt on android. The users.xml file:

  
    somename         


        

Answer 1

I did the following change in users.xsl :

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

To

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

And the problem was solved.

But still don't know why this caused the error.
