I'm trying to write an xslt to generate another xslt that purpose is replacing only all xsl:fo with html tags..XSLT 1
I use CDATA around "xsl" namespace for avoid processing this kind of tag by the xslt. My scope is processing only xsl:fo directive and replace for example :
<fo:table table-layout="fixed" width="100%" font-size="10pt">
<fo:table-column column-width="proportional-column-width(0.65)"/>
<fo:table-column column-width="proportional-column-width(0.35)"/>
<fo:table-body>
<fo:table-row>
<fo:table-cell padding-before="0.5cm"></fo:table-cell>
<fo:table-cell padding-before="0.5cm">
<fo:block>
y
<![CDATA[ --> this is treated as text so i can copy it with <xsl-valueof select="."/>??
<xsl:choose>
<xsl:when test="...xpath'">
<xsl:value-of select="..." />,
</xsl:when>
<xsl:otherwise>
at <xsl:value-of select=..." />,
</xsl:otherwise>
</xsl:choose>]]>
</fo:block>
<fo:block space-before="0.5cm" text-align="center">
x
</fo:block>
</fo:table-cell>
</fo:table-row>
</fo:table-body>
</fo:table>
I want traslate fo:table+fo:table-body with table tag, and fo:table-column with td width="..%", fo:table-row with tr.. Td width is not so easy to retrieve because the width property belong to fo:table-column and fo:table-cell handling the tag.
I try to loop fo:table-column when i read a table-cell i'm writing td and calculate the width using the property column-width obtained by precedent tag fo:table-column: i use the position() of tag table-column (first loop) in the fo:table-cell selection
for example here is my xslt tralslator for xsl:fo (above-mentioned):
<xsl:template name="fo-table">
<xsl:param name="font-size" />
<xsl:param name="width" />
<xsl:variable name="cols" select="count(fo:table-column)"/>
<xsl:if test="fo:table-column">
<xsl:variable name="effective-cols" select="count(fo:table-body/fo:table-row/fo:table-cell)"/>
<xsl:if test="$cols = $effective-cols">
<table>
<xsl:for-each select="fo:table-body/fo:table-row">
<tr>
<xsl:for-each select="parent::*/parent::*/fo:table-column">
<xsl:variable name="width-proportional">
<xsl:value-of select="@column-width"/>
</xsl:variable>
<td>
<xsl:attribute name="width">
<xsl:call-template name="getPercentWidth">
<xsl:with-param name="proportional-value-width"><xsl:value-of select="$width-proportional"/></xsl:with-param>
</xsl:call-template>
</xsl:attribute>
abc <xsl:variable name="vPosition"><xsl:value-of select="position()"/></xsl:variable>
<xsl:for-each select="parent::*/fo:table-body/fo:table-row/*[$vPosition]">
<xsl:value-of select="local-name()"/><xsl:text> #10;</xsl:text> <!-- debug-->
<xsl:choose>
<xsl:when test="fo:block">
<xsl:for-each select="fo:block">
<xsl:call-template name="fo-block-table">
<xsl:with-param name="text-align"><xsl:value-of select="@text-align"/></xsl:with-param>
<xsl:with-param name="space-before"><xsl:value-of select="@space-before"/></xsl:with-param>
</xsl:call-template>
</xsl:for-each>
</xsl:when>
<xsl:otherwise>
empty cell
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</td>
</xsl:for-each>
</tr>
</xsl:for-each>
</table>
</xsl:if>
</xsl:if>
</xsl:template>
<xsl:template name="fo-block-table">
<xsl:param name="text-align" />
<xsl:param name="space-before" />
<xsl:choose>
<xsl:when test="$text-align">
<div>
<xsl:attribute name="text-align">
<xsl:value-of select="normalize-space($text-align)"/>
</xsl:attribute>
<xsl:apply-templates select="."/>
</div>
</xsl:when>
<xsl:otherwise>
<div>
<xsl:apply-templates select="."/>
</div>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template name="getPercentWidth">
<xsl:param name="proportional-value-width"/>
<xsl:variable name="width" select="normalize-space($proportional-value-width)"/>
<xsl:variable name="begin"> <xsl:value-of select="string-length(substring-before($width, '('))" /></xsl:variable>
<xsl:variable name="last"> <xsl:value-of select="string-length(substring-before($width,')'))" /></xsl:variable>
<xsl:variable name="val" select="fn:substring($width, $begin, $last)" />
<xsl:variable name="val1" select="substring-after($val,'(')"/>
<xsl:variable name="cent" select="100"/>
<xsl:value-of select="concat(($val1 * $cent),'%')"/>
</xsl:template>
But i cant realize why all td's contains 'y',x and empty when it will belong only to the empty table-cell, seems it reads all fo:block..
<table>
<tr>
<td width="65%">
abc
table-cell #10;
empty cell
table-cell #10;<div>
y
</div>
<div text-align="center">
x
</div>
</td>
<td width="35%">
abc
table-cell #10;
empty cell
table-cell #10;<div>
y
</div>
<div text-align="center">
x
</div>
</td>
</tr>
</table>
I need to obtain:
<table>
<tr>
<td width="65%">
abc
table-cell #10;
empty cell
</td>
<td width="35%">
abc
table-cell #10;
<div>
y
</div>
<div text-align="center">
x
</div>
</td>
</tr>
</table>
if i replace the second loop xsl : for-each with
xsl : template
don't match anything! Maybe *[$vPosition] doesn't work but it works if i replace number like 1 or 2..
What's wrong?
Thanks in advice!
