Re: Dynamic Header in Page Sequence [region-before]

Sharan,

You can use marker and retrieve marker. The header has to be variable depending on the contents of the page. Example follows. Retrieve marker retrieves whatever you put within the <fo:marker> tags. Those contents are not output on the page. Also, your code used region-start, you want region-before. You used static-content instead of fo:flow.

<fo:static-content flow-name="xsl-region-before">
        <fo:block font-size="16pt" font-weight="bold" font-family="sans-serif">
        <xsl:text> Car: </xsl:text>
        <fo:retrieve-marker retrieve-class-name="car-category" retrieve-boundary="page" 
retrieve-position="first-starting-within-page"/>
        </fo:block>
</fo:static-content>

<fo:flow flow-name="xsl-region-body">
        <xsl:for-each select="/car">
        <fo:block><fo:marker marker-class-name="car-category"><xsl:value-of 
select="Car/@category"/></fo:marker>
        <xsl:value-of select="@name"/>
        . . .
        </fo:block>
</fo:flow>

Hi XSL FOP Developers,

     I want to ask if it is possible to have a dynamic Header implemented
in a Page-Sequence.

     something like ...


     <fo:static-content flow-name="xsl-region-start">
            <fo:block font-size="16pt" font-weight="bold"
font-family="sans-serif">
                  <xsl:text> Car: </xsl:text>
                  <xsl:value-of select="Car/@category"/>
            </fo:block>
     </fo:static-content>


     <fo:static-content flow-name="xsl-region-body">

        <!-- XSL FO code to process the xml goes here... -->

<!-- This body content gets "page header" using the
xsl-region-start above -->
<!-- Is is possible to have a different header for this/each page
-->
<!-- depending on the data being processed eg. let's say we have a
xml having car schema -->
<!-- would it be possible to have the page header vary depending on
the car detail being displayed ??? -->
<!-- (assuming each car gets displayed on its own page i.e.
separate page for each car) -->
</fo:static-content>


     Assuming an XML like :-

      <Vehicle type="4 wheel drive">

         <car category="sedan">
             <!-- Car details here... -->
         </car>

         <car category="sports">
             <!-- Car details here... -->
         </car>

      </Vehicle>


      Any ideas ? Is there a better way to achieve the same results ? Any
helps/hints/suggestions appreciated.

      Thanks!,

      Dharmendra
