Hi Woody,
I have this section of an xml file that needs to be rendered
to a table
<TGROUP>
<COLSPEC COLNUM="1" COLNAME="1" COLWIDTH="0.713in"/>
<COLSPEC COLNUM="2" COLNAME="2" COLWIDTH="1.179in"/>
<COLSPEC COLNUM="3" COLNAME="3" COLWIDTH="1.272in"/>
<COLSPEC COLNUM="4" COLNAME="4" COLWIDTH="3.283in"/>
[...]
Problem here is that I need to change the COLWIDTH into
percentages to
render out to the table.
if you want to avoid using node-set() then you will need a recursive
template to get you the total column width from which to calculate the
percentages.
To get rid of "in" etc. you can use
translate(@COLWIDTH,"abcdefghijklmnopqrstuvwxyz","") to get just the
numerical value.
<xsl:template name="get_total_width">
<xsl:param name="nodes" select="/.."/>
<xsl:param name="sub_total" select="0"/>
<xsl:variable name="width"
select="number(
translate($nodes/@COLWIDTH,
'abcdefghijklmnopqrstuvwxyz',
'')
)"/>
<xsl:choose>
<xsl:when test="count($nodes) > 1">
<xsl:call-template name="get_total_width">
<xsl:with-param name="nodes" select="$nodes[position() != 1]"/>
<xsl:with-param name="sub_total" select="$sub_total +
$width"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$sub_total + $width"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
then you can call it to get the total for the table you're looking at:
<xsl:variable name="total_width">
<xsl:call-template name="get_total_width">
<xsl:with-param name="nodes" select="TGROUP/COLSPEC[(_at_)COLNUM]"/>
</xsl:call-template>
</xsl:variable>
and as long as the variable's in scope, use it to calculate the percentage.
hth,
