xml-dev - Namespaces in XML

["Kumar V." <vkumar@techbooks.com>]

I am trying to create a stylesheet for XML project. 

I am using IE 5.0 to browse the file.  I am facing few
problems.

   1. Could you please give a brief description about the name
spaces(different types) & Strings.

   2. If I use
"xmlns:xsl="http://www.w3.org/TR/WD-xsl"
, Below condition is not working.

       <xsl:template
match="keyword">
       <xsl:if
test="keyword['position() != last']">
       <xsl:apply-templates/>, 
        </xsl:if>
       <xsl:if
test="keyword['position() = last']">
       <xsl:apply-templates/>. 
        </xsl:if>
        </xsl:template>

   3. Strip-space, Preserve-space function is also not working
in IE5.0.

       I would be grateful to you if you
could please help me out to clear the above errors. Please tell the some
browser names.

       Eagerly awaiting for your
reply.      
    
Regards,
Kumar V.
