RE: fun with fo tab formatting

Hi List Members,

Eliot and Ken - thanks for pointing me in the right direction...  This
is as far as I have gotten:

<xsl:template match="ws:tab">
        
        <xsl:if test="position()=1">
                <fo:table>
                        <fo:table-body>
                                <fo:table-row>
        </xsl:if>
                                
        <xsl:element name="fo:table-cell">
                <xsl:attribute name="width">
                        <xsl:call-template name="get-width">
                                <xsl:with-param name="list">
                                  <xsl:choose>
                                        <xsl:when test="parent::tabs">
                                                <xsl:value-of
select="parent::tabs"/>
                                        </xsl:when>
                                        <xsl:otherwise>
                                                <xsl:variable
name="styleName" select="parent::style"/>
                                                <xsl:value-of
select="//ws:textStyle[(_at_)name=$styleName]/ws:blockAttr/@tabs"/>
                                        </xsl:otherwise>
                                  </xsl:choose>
                                </xsl:with-param>
                                <xsl:with-param name="curpos">
                                  <xsl:choose>
                                        <xsl:when
test="preceding-sibling::br">
                                                <xsl:value-of
select="count(preceding-sibling::tab)-position()"/>
                                        </xsl:when>
                                        <xsl:otherwise>
                                                <xsl:value-of
select="position()"/>
                                        </xsl:otherwise>
                                  </xsl:choose>
                                </xsl:with-param>
                        </xsl:call-template>
                </xsl:attribute>
        </xsl:element>
        <fo:block/>
        <xsl:element name="fo:table-cell">
                <xsl:apply-templates/>
        </xsl:element>
                                
        <xsl:if test="position()=parent::ws:tab[last()]">
                                </fo:table-row>
                        </fo:table-body>
                </fo:table>
        </xsl:if>       
        
</xsl:template>

First, it won't let me save this, because it doesn't like me opening
tags in one statement and closing them in another...any way I can get
around this?

Second...I've reached a wall with my new "get-width" template:

<xsl:template name="get-width">
        <xsl:param name="list"/>
        <xsl:param name="curpos"/>
        <xsl:variable name="nlist"
select="concat(normalize-space($list), ' ')"/>
        <xsl:variable name="first" select="substring-before($nlist, '
')"/>
        <xsl:choose>
                <xsl:when test="$curpos=1">
                        <xsl:value-of select="$first"/>
                </xsl:when>
                <xsl:otherwise>
                        <!--want list[curpos] - list[curpos-1]...I
think.  But how???-->
                </xsl:otherwise>
        </xsl:choose>
</xsl:template>

If the curpos(tab) is 1, then I can just output the first string.
However, I can't come up with an algorithm that works for the rest of
the items.  If curpos is 2 or 3, or 4 or whatever, I want the tab width
output to be list[curpos] - list[curpos-1] but I don't know how to
express that here.  It's driving me batty!

Thanks for all your help/advice with this stuff - in case you couldn't
already tell, I find this very!! confusing.
