I have been attempting to perform multiple (different) string replacement with recursion and I have hit a roadblock. I have sucessfully gotten the first replacement to work, but the subsequent replacements never fire. I know this has to do with the recursion and how the with-param string is passed back into the call-template. I see my error and why the next xsl:when never fires, but I just cant seem to figure out exactly how to pass the complete modified string from the first xsl:when to the second xsl:when. Any help is greatly appreciated.

<xsl:template name="replace">
    <xsl:param name="string" select="." />
    <xsl:choose>
        <xsl:when test="contains($string, '&#13;&#10;')">
            <xsl:value-of select="substring-before($string, '&#13;&#10;')" />
            <br/>
            <xsl:call-template name="replace">
                <xsl:with-param name="string" select="substring-after($string, '&#13;&#10;')"/>
            </xsl:call-template>
        </xsl:when>
        <xsl:when test="contains($string, 'TXT')">
            <xsl:value-of select="substring-before($string, '&#13;TXT')" />
            <xsl:call-template name="replace">
                <xsl:with-param name="string" select="substring-after($string, '&#13;')" />
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
            <xsl:value-of select="$string"/>
        </xsl:otherwise>

    </xsl:choose>
</xsl:template>
