Execute Stylesheet

Hello,
I have a question, I am embarrassed to ask as it seems like it should be so easy

I have basically copied an xsl stylesheet from
http://www.xml.com/pub/a/2003/05/07/tr.html, with a slight
modification to the string that is being tokenized.  My plan is to
further modify and wrap the values in the file with elements.

I am using Oxygen as my XML editor of choice.

My question is how do I actually run this stylesheet?  I am used to
running a stylesheet against an xml file but I am at a loss as to how
to execute this one against the text file?  Can I run it from within
Oxygen or do I need to run it with a command line?

I am using XSLT 2.0 (Saxon)

My (copied) stylesheet is as follows

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:variable name="in" select="unparsed-text('c:\comma_delimited.txt')"/>
    <xsl:template match="/">
        <xsl:variable name="tokenizedSample" select="tokenize($in,',')"/>
         <xsl:for-each select="$tokenizedSample">
            <xsl:value-of select="."/>
            <xsl:text>! </xsl:text>
        </xsl:for-each>
     </xsl:template>
 </xsl:stylesheet>

Thanks
