Re: converting cals table to html using xslt

I am outputing to both XHTML and XSL:FO. I need only a subset of the
cals table implemented. The two features I describe below are critical
and have to be implemented. I am not sure how to start it. Her eis a
snippet of the transformation that I have written for the table: This
does not include colwidth and namest.

For XSL:FO:
-----------------------------------------------------------------------------
-----------------------------
<xsl:template match="table">

			<xsl:apply-templates select="tgroup"/>
		</fo:block>

		<fo:block space-before="6pt" space-before.conditionality="retain"/>
	</xsl:template>
	<xsl:template match="tgroup">
		<fo:table keep-together.within-page="always" text-align="left"
border="1pt solid black">
			<xsl:call-template name="set_columns">
				<xsl:with-param name="count" select="@cols"/>
				<xsl:with-param name="columns" select="@cols"/>
			</xsl:call-template>
			<fo:table-header>
				<fo:table-row line-height="12pt" font-size="11pt"
font-weight="bold" background-color="#FFFFFF">
					<xsl:apply-templates select="colspec"/>
				</fo:table-row>
			</fo:table-header>
			<xsl:apply-templates select="thead"/>
			<xsl:apply-templates select="tbody"/>
		</fo:table>
	</xsl:template>
	<xsl:template match="colspec">
		<fo:table-cell border-right-style="solid"
border-bottom-style="solid" border-width="1pt"
border-right-color="white" padding-start="4pt" padding-top="3pt"
padding-bottom="3pt" display-align="before">
			<fo:block>
				<fo:inline color="white">
					<xsl:value-of select="@colname"/>
				</fo:inline>
			</fo:block>
		</fo:table-cell>
	</xsl:template>
	<xsl:template match="thead">
		<fo:table-body>
			<xsl:apply-templates select="row"/>
		</fo:table-body>
	</xsl:template>
	<xsl:template match="tbody">
		<fo:table-body>
			<xsl:apply-templates select="row"/>
		</fo:table-body>
	</xsl:template>
	<xsl:template match="row">
		<fo:table-row line-height="12pt" font-size="11pt"
background-color="#FFFFFF">
			<xsl:apply-templates select="entry/text/para"/>
		</fo:table-row>
	</xsl:template>
	<xsl:template match="entry/text/para">
		<fo:table-cell start-indent="0pt" text-align="left"

		</fo:table-cell>
	</xsl:template>
	<xsl:template name="set_columns">
		<xsl:param name="count"/>
		<xsl:param name="columns"/>
		<xsl:if test="$count !=0">
			<xsl:call-template name="set_columns">
				<xsl:with-param name="count" select="$count -1"/>
				<xsl:with-param name="columns" select="$columns"/>
			</xsl:call-template>
		</xsl:if>
	</xsl:template>

Implementing a cals table stylesheet is no mean feat, and you seem to
be at the very early stages.  I would get your problem defined first -
do you need to implement the whole of cals or a subset?  Are you
outputting to both XHTML and XSL:FO?  It could be sufficient to use
the Oasis table stylesheets in docbook.

It's a massive task as the cals standard is so loose - its certainly
not something to undertake lightly.  For example, in some
circumstances to correctly work out the row and col spans you need to
normlize the table first - possible but pretty much a nightmare.  I
don't think there's a stylesheet out there that fully implements the
spec.
