This gets monotonous after a while. It would be nice if <xsl:value-of>
could take an attribute which would provide a default value if the select
produces an empty result!
Make a template that does just that.
<xsl:template name="monotonous">
<xsl:param name="str" select="." />
<xsl:value-of select="$str" />
<xsl:if test="string-length() = 0">
^^ Is this a typo?
<xsl:text> </xsl:text>
</xsl:if>
</xsl:call-template>
Actually, since a named template does not change to another context node, you
should be able to dispense with the "xsl:param" altogether. Thus:
<xsl:template name="monotonous">
<xsl:value-of select="." />
<!-- put " " in place of nothing -->
<xsl:if test="string-length(.) = 0">
<xsl:text> </xsl:text>
</xsl:if>
<!-- or whatever other way to get an " "
into an empty "td" element -->
</xsl:call-template>
and then you have
<td>
<xsl:call-template name="monotonous" />
</td>
Actually, I would rather put the "td" element into the named template, like so:
<xsl:template name="tablecell">
<td>
<xsl:value-of select="." />
<xsl:if test="string-length(.) = 0">
<xsl:text> </xsl:text>
</xsl:if>
</td>
</xsl:template>
So that the markup surrounding the "call-template" element can be simplified
even further, to something like this:
<xsl:call-template name="tablecell"/>
I don't think you need to explicitly pass the parameter because of the
default value, but play with it to make sure. You may need to include the
line
<xsl:with-param name="str" select="." />
but I hope not.
You don't need the "xsl:with-param" element. That would defeat the whole point
of the default value on the "xsl:param" element.
