Re: [xsl] Building tables with XSLT

[juggy at gmx dot net]

Hi Dan,

Seems like you are thinking about something like a varaiable update as 
used in ordinary programming languages. A solution that comes to my mind 
would be to do it as follows (I haven't tried it for bugs, but maybe 
this might help anyway):
<xsl:template>
	<xsl:param name="width">4</xsl:param> <!-- standard width -->
	<xsl:for-each select="IMAGES/IMAGE[(postion() % $width) = 0">
		<tr><td>
			<xsl:call-template name="rowdisplay">
				<xsl:with-param name="pos"><xsl:value-of select="position" 
/></xsl:with-param>
				<xsl:with.param name="width"><xsl:value-of select="$width" 
/></xsl:template>
			</xsl:call-template>
			</td></tr>
	</xsl:for-each>
</xsl:template>
<xsl:template name="pos">
	<xsl:param name="pos" />
	<xsl:param name="width" />
	<xsl:for-each select="IMAGES/IMAGE[position() >= $pos and position() 
<($pos+$width)">
	<td>...put your image...</td>
	</xsl:for-each>
</xsl:template>

Maybe this helps. But if anyone knew a way to change the value of a 
variable without nesting templates or such, I would like to hear about 
it - would prevent constructs like the above IMHO.

Juggy
