org.apache.xalan.xslt.XSLProcessorException: String in

hi everyone,
	I have a template which takes a string parameter and inserts <br/>s
in the string if there are no spaces in the string and the string is greater
than 32 characters.  It just prints out the string as is if there are
spaces.  This works just fine unless I try to pass it a string with a
special character.  For example, my string = "It doesn't work like this." or
my string = "It doesn&apos;t work like this."  This string gets passed to
the XSLT as an <xsl:param .../>.  If I pass the template a string with an
apostraphe then I get the following error:
org.apache.xalan.xslt.XSLProcessorException: String index out of range: 29

Here is the template:

<xsl:template name="splitString">
	<xsl:param name="string"/>
	<xsl:choose>
		<xsl:when test="string-length($string) > 32 and
not(contains(substring($string,1,32), ' '))">
			<xsl:value-of select =
"substring($string,1,32)"/><BR/>
			<xsl:call-template name="splitString">
				<xsl:with-param name="string"
select="substring($string,33,string-length($string))" />
			</xsl:call-template>
		</xsl:when>
		<xsl:otherwise>
			<xsl:value-of select="$string"/>
		</xsl:otherwise>
	</xsl:choose>
</xsl:template>

Does anyone know why this exception occurs here?

Any help would be greatly appreciated,
Heather
