You can't do this as a simple function. You either need an extension
function or recursive named templates.
If you know the string in advance, you could use a substring:
substring('abcabcabcabcabcabcabcabcabcabcabcabcabc',3*3)
But the named template is the most general solution:
<xsl:call-template name="replicate">
<xsl:with-param name="string" select="'abc'"/>
<xsl:with-param name="num" select="3"/>
</xsl:call-template>
<xsl:template name="replicate">
<xsl:param name="string" select="''"/>
<xsl:param name="num" select="1"/>
<xsl:value-of select="$string"/>
<xsl:if test="$num > 1">
<xsl:call-template name="replicate">
<xsl:with-param name="string" select="$string"/>
<xsl:with-param name="num" select="$num - 1"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
