How do I get a value from an xml file by using an xsl file - the files are in different directories

I'm a newbie to xml and xsl, I've looked everywhere on the web and I know this is probably a straight forward answer but I can't seem to be able to get it to work. The problem I have is that I have a .xml file and a .xsl file (both are in totally different directories) and I am trying to get the data from the .xml file, but when I view it in IE browser; I just get a blank screen. Please help.

Test.xml

<root>
 <tags>abc</tags>
 <tags>def</tags>
 <tags>ghi</tags>
 <tags>jkl</tags>
 <tags>mno</tags>
 <tags>qpr</tags>
</root>

Test.xsl

 <?xml version="1.0" encoding="UTF-8"?>
 <xsl:stylesheet version="1.0" xmlns:xsl="http://ift.tt/tCZ8VR">

 <xsl:variable name="file" select="'C:\Test.xml'"/>
 <xsl:variable name="info" select="document($file)/root/tags"/>

 <xsl:template match="/">
  <xsl:for-each select="tags">
   <xsl:value-of select="$info"/>
  </xsl:for-each>
 </xsl:template>                

</stylesheet>

Output should be:

abcdefghijklmnopqr
