Its the right idea but its wrong in several places, firstly your
with-params:

 <xsl:with-param str="Hello"/>

Should be:

 <xsl:with-param name="str" select="'Hello'"/>

There is no param to take 'str' in "repeater", and the value-of is below
your call-template so it won't output anything!

Its normally a good idea to test your code before you post it :) 

Here's a working version:

<xsl:template match="/">
	<xsl:call-template name="repeater">
		<xsl:with-param name="theString" select="'Hello'"/>
		<xsl:with-param name="numberOfTimes" select="20"/>
	</xsl:call-template>
</xsl:template>

<xsl:template name="repeater">
	<xsl:param name="theString" select="''"/>
	<xsl:param name="numberOfTimes" select="0"/>
	<xsl:if test="$numberOfTimes > 0">
	   <xsl:value-of select="$theString"/>
	   <xsl:call-template name="repeater">
	     <xsl:with-param name="theString" select="$theString"/>
	     <xsl:with-param name="numberOfTimes" select="$numberOfTimes
- 1"/>
	   </xsl:call-template>		
	</xsl:if>
</xsl:template>
