This is an awkward problem in XSLT (not hard, just awkward).  Your
input document is more of a text document than an XML document, because
the "interesting" part of the parsing is about parsing a text string,
not XML.

Here's a crude recursive solution.

<xsl:template name="foo" >
<xsl:param name="list" select="/.." />
    <xsl:variable name="car" select="substring-before($list,',')" />
    <xsl:variable name="cdr" select="substring-after($list,',')" />
    <xsl:choose><xsl:when test="$car" >
        <MyNewTag><xsl:value-of select="($car)" /></MyNewTag>
        <xsl:call-template name="foo" >
            <xsl:with-param name="list" select="($cdr)" />
        </xsl:call-template>
    </xsl:when>
    <xsl:when test="$list" ><MyNewTag><xsl:value-of select="$list"
/></MyNewTag></xsl:when>
    </xsl:choose>
</xsl:template>

<xsl:template match="mytag" >
    <MyNewTags>
    <xsl:call-template name="foo" >
        <xsl:with-param name="list" select="text()" />
    </xsl:call-template>
    </MyNewTags>
</xsl:template>
