problem chain templates together

Hi,

I have a problem figure out how to chain my templates
together.  My XML has alternating organization and
user  sections, where there could be multiple user
records.  One organization and the following user
section belongs to the same organization and therefore
processed together.  My strategy is to search for the
unique section headings, and then process the rows
after the heading, **but before the start of the next
heading**.  The last part is where I can't seem to
figure out.  Following are the XML and XSL I currently
have:

XML:
<row row="1">
	<cell column="1">*SupplierOrganizationCode</cell>
	<cell column="2">SupplierName</cell>
	<cell column="3">Address</cell>
</row>
<row row="2">
	<cell column="1">s1</cell>
	<cell column="2">test name for s1</cell>
	<cell column="3">5 Brown Road, Boston, MA</cell>
</row>
<!-- row 3 is empty to separate the sections -->
<row row="4">
	<cell column="1">EmailAddress</cell>
	<cell column="2">WorkPhoneNumber</cell>
</row>
<!-- could have n contacts for s1, this example shows
2 -->
<row row="5">
	<cell column="1">test1@xxxxxx</cell>
	<cell column="2">(800) 837-8171</cell>
</row>
<row row="6">
	<cell column="1">test2@xxxxxx</cell>
	<cell column="2">(800) 837-8172</cell>
</row>
<!-- row 7 is empty to separate the sections -->
<row row="8">
	<cell column="1">*SupplierOrganizationCode</cell>
	<cell column="2">SupplierName</cell>
	<cell column="5">Address</cell>
</row>
<row row="9">
	<cell column="1">s2</cell>
	<cell column="2">test name for s2</cell>
	<cell column="5">200 Wheeler Road, Boston, MA</cell>
</row>
<!-- row 10 is empty to separate the sections -->
<row row="11">
	<cell column="1">EmailAddress</cell>
	<cell column="2">FaxNumber</cell>
	<cell column="3">WorkPhoneNumber</cell>
</row>
<!-- could have n contacts for s2, this example shows
1 -->
<row row="12">
	<cell column="1">test1@xxxxxx</cell>
	<cell column="2">(800) 837-8271</cell>
</row>

XSL:
<xsl:template match="/">
	<xsl:apply-templates select="row"
mode="SupplierHeader"/>
</xsl:template>
<xsl:template match="row" mode="SupplierHeader">
	<!-- find the Supplier header row.  The first element
is SupplierOrganizationCode or
*SupplierOrganizationCode -->
	<xsl:if test="cell[1] = 'SupplierOrganizationCode' or
substring(cell[1], 2) = 'SupplierOrganizationCode'">
		<xsl:apply-templates
select="following-sibling::row[@row = node()/@row +
1]" mode="Supplier"/>
	</xsl:if>
</xsl:template>
<xsl:template match="row" mode="Supplier">
	<!-- display supplier info omitted -->
	<xsl:apply-templates select="following-sibling::row"
mode="ContactHeader"/>
</xsl:template>
<xsl:template match="row" mode="ContactHeader">
	<!-- find the Contact header row.  The first element
is EmailAddress or *EmailAddress -->
	<xsl:if test="cell[1] = 'EmailAddress' or
substring(cell[1], 2) = 'EmailAddress'">
		<xsl:apply-templates
select="following-sibling::row[@row &gt; node()/@row
and @row &lt; ???]" mode="Contact"/>
	</xsl:if>
</xsl:template>
<xsl:template match="row" mode="Contact">
	<!-- display contact info omitted -->
</xsl:template>

In ContactHeader template, the ??? in
xsl:apply-templates is what I can't seem to figure
out.  Any help would be very much appreciated.

Thanks,
Xiaocun
