Using XSLT 1.0 apply-templates only on certain attribute values - xslt

Question

I'm trying to stay away from a procedural approach with this solution and I'm not sure that's possible.
Here's my XML:
<countData>
<count countId="37" name="Data Response 1">
<year yearId="2013">
<month monthId="5">
<day dayId="23" countVal="6092"/>
<day dayId="24" countVal="6238"/>
<day dayId="27" countVal="6324"/>
<day dayId="28" countVal="6328"/>
<day dayId="29" countVal="3164"/>
</month>
<day dayId="23" countVal="7000"/>
<day dayId="24" countVal="7000"/>
<day dayId="27" countVal="7000"/>
<day dayId="28" countVal="7000"/>
<day dayId="29" countVal="7000"/>
</month>
</year>
</count>
<count countId="39" name="Data Response 2">
<year yearId="2013">
<month monthId="5">
<day dayId="23" countVal="675"/>
<day dayId="24" countVal="709"/>
<day dayId="27" countVal="754"/>
<day dayId="28" countVal="731"/>
<day dayId="29" countVal="377"/>
</month>
</year>
</count>
I want to apply-templates (in this example) for all count/#countIds that are 37 or 39. Here's where I am:
<xsl:template match="/">
<xsl:apply-templates mode="TimeFrame"/>
</xsl:template>
<xsl:template match="*" mode="TimeFrame">
<xsl:if test="count[#countId=37] or count[#countId=39]">
<magic>Only hitting this once for countId 37</magic>
</xsl:if>
</xsl:template>
I'm going to have quite a few of these templates with "modes" since I'm processing the same response a multitude of different ways.
Not sure how I'm missing the "range" match and only getting 1.
I'm sure it has to do with my "procedural mind". :)
Any help on this would be great!
Thanks,

Your main template, <xsl:template match="/">, runs only once - namely for the <countData> element.
Which means that you either forgot to recurse:
<xsl:template match="*" mode="TimeFrame">
<xsl:if test="count[#countId=37] or count[#countId=39]">
<magic>Only hitting this once for countId 37</magic>
</xsl:if>
<xsl:apply-templates mode="TimeFrame"/> <!-- ! -->
</xsl:template>
...or you failed to set the right context for the the main template:
<xsl:template match="/countData"><!-- ! -->
<xsl:apply-templates mode="TimeFrame"/>
</xsl:template>
<!-- or, alternatively -->
<xsl:template match="/">
<xsl:apply-templates select="countData/*" mode="TimeFrame"/>
</xsl:template>
