Re: [xsl] Creating nested output from <xsl:if>'s

[Kevin Jones <kjones@xxxxxxxxxxx>]

Leaving aside the question of why you are using <xsl:text> 
for the output you might find recursion more maintainable 
than "if" although a little more verbose. Perhaps something 
like this (untested).

<xsl:template match="prosody" name="format-prosody">
 <xsl:param name="atts" select="@*"/>

   <xsl:for-each select="$atts[1]">
   <xsl:choose>

    <xsl:when test="self::pitch='x-high'">
     <xsl:text>&lt;PITCH BASE="70%"&gt;</xsl:text>
     <xsl:call-template name="format-prosody">
	<xsl:with-param name="atts" select="$atts[position()>1]"/>
     </xsl:call-template>
     <xsl:text>&lt;/PITCH&gt;</xsl:text>
    </xsl:when>

    <xsl:when test="self::rate='slow'">
     <xsl:text>&lt;RATE SPEED="-40%"&gt;</xsl:text>
     <xsl:call-template name="format-prosody">
	<xsl:with-param name="atts" select="$atts[position()>1]"/>
     </xsl:call-template>
     <xsl:text>&lt;/RATE&gt;</xsl:text>
    </xsl:when>

    <xsl:otherwise>
     <xsl:call-template name="format-prosody">
	<xsl:with-param name="atts" select="$atts[position()>1]"/>
     </xsl:call-template>
    </xsl:otherwise>

   </xsl:choose>
   </xsl:for-each>

   <xsl:if test="count($atts)=0">
	   <xsl:apply-templates/>
   </xsl:if>

</xsl:template>
