escaping quotes with \"

I found this snippet of code on the faq but don't quite understand it.  So
if I want to escape all my quotes I just add this XSL to the bottom of my
page or do I need to associate every value of with it?

Please help out the newbie.. Thanks

<xsl:variable name="noQuote"><xsl:call-template name="cleanQuote">
<xsl:with-param name="string"><xsl:value-of select="$noLF"
/></xsl:with-param>
</xsl:call-template>
</xsl:variable>

<xsl:template name="cleanQuote">
<xsl:param name="string" />
<xsl:if test="contains($string, '&#x22;')">
<xsl:value-of
    select="substring-before($string, '&#x22;')" />\"<xsl:call-template
    name="cleanQuote">
                <xsl:with-param name="string"><xsl:value-of
select="substring-after($string, '&#x22;')" />
                </xsl:with-param>
        </xsl:call-template>
</xsl:if>
<xsl:if test="not(contains($string, '&#x22;'))"><xsl:value-of
select="$string" />
</xsl:if>
</xsl:template>
