how to design a template in xslt which adds strong tag based on some conditions - xslt

Question

I have input xml of the form
<content xml:lang="en" xmlns:w="http://www.w.com/sch/W">
<w:firstRowHeader>true</w:firstRowHeader>
<w:firstColumnHeader>true</w:firstColumnHeader>
<w:customTable>
<w:tableContent>
<w:row>
<w:cell>
<w:spanInfo backgroundColor="Yellow" columnWidth="5" isRowHeader="true"/>
<text>ghnmghmg</text>
</w:cell>
<w:cell>
<w:spanInfo backgroundColor="Yellow" isRowHeader="false"/>
<text>ghmhgmgm</text>
</w:cell>
</w:row>
<w:row>
<w:cell>
<w:spanInfo backgroundColor="Yellow" columnWidth="5" isRowHeader="false"/>
<text>vj</text>
</w:cell>
<w:cell>
<w:spanInfo columnWidth="5" isRowHeader="true"/>
<text>mm</text>
</w:cell>
</w:row>
</w:tableContent>
</w:customTable>
</content>
This needs to be transformed to a xml in which:
w:tableContent mapped to tablecontent and
then under tablecontent tag 'table','tbody' tags are created
w:row mapped to tr tag
w:cell mapped to td tag
and conditions are like
if only 1st w:cell element in w:row has an attribute isRowHeader as "true" then every 'td' element under its respective 'tr' tag should contain a 'strong' tag and ignore 2nd w:cell's isRowHeader
if w:firstRowHeader is 'true' then transformed table should have 1st row text in bold, i.e., every 'td' tag in 1st row of table should contain 'strong' tag
if w:firstColumnHeader is 'true' then transformed table should have 1st column text in bold, i.e., every tr tag's 1st 'td' tag of table should contain 'strong' tag
Transformed xml:
<content>
<tablecontent>
<table cellspacing="1" cellpadding="1" border="1" style="WIDTH: 100%" title="Title" xmlns="http://www.w3.org/1999/xhtml">
<tbody>
<tr>
<td style="BACKGROUND-COLOR: Yellow; WIDTH: 5%"><strong>ghnmghmg</strong></td>
<td style="BACKGROUND-COLOR: Yellow"><strong>ghmhgmgm</strong></td>
</tr>
<tr>
<td style="BACKGROUND-COLOR: Yellow; WIDTH: 5%">vj</td>
<td style="WIDTH: 5%">mm</td>
</tr>
</tbody>
</table>
</tablecontent>
</content>
This is the xslt template that i have tried but cant figure out how to implement these 'strong' tags in it...
XSLT:
<xsl:template match="w:tableContent">
<xsl:variable name="var3" select="../w:firstRowHeader"/>
<xsl:variable name="var4" select="../w:firstColumnHeader"/>
<tablecontent>
<table cellspacing="1" cellpadding="1" border="1" style="WIDTH: 100%" title="Title" xmlns="http://www.w3.org/1999/xhtml" >
<tbody>
<xsl:for-each select="child::*">
<xsl:choose>
<xsl:when test="name()='w:row'">
<tr>
<xsl:for-each select="child::*">
<xsl:choose>
<xsl:when test="name()='w:cell'">
<td>
<xsl:for-each select="child::*">
<xsl:choose>
<xsl:when test="name()='w:spanInfo'">
<xsl:variable name="var8" select="#backgroundColor" />
<xsl:variable name="var9" select="#columnWidth" />
<xsl:variable name="var10" select="#isRowHeader" />
<xsl:if test="$var8!='' or $var9!=''">
<xsl:attribute name="style">
<xsl:if test="$var8!='' and $var9!=''">
<xsl:value-of select="concat('BACKGROUND-COLOR: ',$var8,'; WIDTH: ',$var9,'%')" />
</xsl:if>
<xsl:if test="$var8!='' and not($var9)">
<xsl:value-of select="concat('BACKGROUND-COLOR: ',$var8)" />
</xsl:if>
<xsl:if test="not($var8) and $var9!=''">
<xsl:value-of select="concat('WIDTH: ',$var9,'%')" />
</xsl:if>
</xsl:when>
<xsl:when test="name()='text'">
<xsl:if test="../w:spanInfo/#isRowHeader='true'">
<strong><xsl:value-of select="." /></strong>
</xsl:if>
<xsl:if test="../w:spanInfo/#isRowHeader!='true' or not(../w:spanInfo/#isRowHeader) ">
<xsl:value-of select="." />
</xsl:if>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</td>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</tr>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</tbody>
</table>
</tablecontent>
</xsl:template>
But the above template adds 'strong' tags to the cells which has only w:spanInfo's 'isRowHeader' attribute as 'true'. But I require to get 'strong' tag to be added to 2nd cell content also irrespective of its w:spanInfo's 'isRowHeader' attribute's value, provided if 1st cell already has 'isRowHeader' attribute as 'true'.

This XSLT 1.0 style-sheet ...
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:w="http://www.w.com/sch/W">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<content>
<xsl:apply-templates select="*/*/w:tableContent"/>
</content>
</xsl:template>
<xsl:template match="w:tableContent">
<table cellspacing="1" cellpadding="1" border="1" style="WIDTH: 100%" title="Title" xmlns="http://www.w3.org/1999/xhtml">
<tbody>
<xsl:apply-templates select="w:row" />
</tbody>
</table>
</xsl:template>
<xsl:template match="w:row">
<tr>
<xsl:apply-templates select="w:cell" />
</tr>
</xsl:template>
<xsl:template match="w:cell">
<xsl:variable name="style">
<xsl:if test="w:spanInfo/#backgroundColor">
<xsl:value-of select="concat('BACKGROUND-COLOR: ',w:spanInfo/#backgroundColor)" />
</xsl:if>
<xsl:if test="w:spanInfo/#columnWidth">
<xsl:if test="w:spanInfo/#backgroundColor">
<xsl:value-of select="'; '" />
</xsl:if>
<xsl:value-of select="concat('WIDTH: ',w:spanInfo/#columnWidth,'%')" />
</xsl:if>
</xsl:variable>
<td>
<xsl:if test="$style">
<xsl:attribute name="style"><xsl:value-of select="$style" /></xsl:attribute>
</xsl:if>
<xsl:apply-templates select="text" />
</td>
</xsl:template>
<xsl:template match="w:cell/text[
not( ../../preceding-sibling::w:row) and (/*/w:firstRowHeader='true')
or
not( ../preceding-sibling::w:cell) and (/*/w:firstColumnHeader='true')
or
(../preceding-sibling::w:cell[last()]/w:spaninfo/#isRowHeader='true')
]">
<strong><xsl:call-template name="default-rendering-of-text" /></strong>
</xsl:template>
<xsl:template match="text" name="default-rendering-of-text">
<xsl:value-of select="." />
</xsl:template>
</xsl:stylesheet>
... should satisfy your rules. The 3 conditions that you have set for bold/strong rendering are made plainly evident by the predicate of the match condition for text elements (near the end of the style-sheet). By avoiding unnecessary xsl:for-each we can use a simpler, more modular and more readable template based solution.
