As I said, XSLT doesn't work with tags.

You could do, or you could most likely use the simpler method of
processing n records at a time (for n = 65535 or 500 or whatever you
need) that I show above.

				<xsl:value-of select="substring($FILE, 1, string-length($FILE) -4)">
				</xsl:value-of>

value of has to be empty.


	<xsl:template match="record" mode="item">
		<xsl:param name="remaining" select="$GROUPSIZE - 1"/>
		<Row>
		<xsl:for-each select="*">
			<xsl:call-template name="cell"/>
		</xsl:for-each>
		</Row>
		<xsl:if test="$remaining">
			<xsl:apply-templates select="following-sibling::record[1]" mode="item" >
			<xsl:with-param name="remaining" select="$remaining -1" />
			</xsl:apply-templates>
		</xsl:if>
  </xsl:template>


This appears to be processing $GROUPSIZE siblings at a time, if so there
is no need to use recursion here (processors will not be optimised to
recurse that deeply, most likely) you can just do
<xsl:apply-templates
select="following-sibling::record[position()&lt;$GROUPSIZE]
no need to explictly recurse.

		<xsl:if test='number(.)'>
		<xsl:if test="not(number(.))">

testing for zzz and not(zzz) is always equivalent to an axsl:choose with
a single test and an otherwise. In this case I don't think you want to
test number(.) as that will first coerce the current node to being a
number, and then be true if that number is non-zero. Perhaps that is
what you want but I suspect that you want to test
test="number(.)=number(.)"
which is true if the content coerces to a number that is not NotANumber.
