Avoiding Blank Pages When using Multiple Page Sequences

[Ram Krishnamoorthi <ra...@yahoo.com>]

Hello all,
Brand New FOP user here..still finding my way through
the Features. Please bear with me. 

I am using it to convert XML Files into PDF Documents.

I am using Multiple Page-Sequences to avoid Memory
Issues. If I understand right, a New Page Sequence
instantiates a New Page automatically. 

In each of my Page Sequence, I am calling one or two
XSL Templates. In my case, it is possible that I may
not have any data to Print in a Page Sequence because
of the absence of specific tags in the Input XML
File.I would like to avoid having blank pages in the
PDF document. Is there any attribute I can specify to
achieve the same? 

Thanks 
Ram

My thought precisely.

Here is a fragment from a stylesheet I wrote to print books (for the 
software industry):

  <xsl:if test="$showIndex='yes'">
    <fo:page-sequence master-reference="index">
      <!-- static-content and flow goes here, to define the index pages 
-->
    </fo:page-sequence>
  </xsl:if>

The $showIndex variable gets populated at the top of the stylesheet, based 
on an implied (and so not always present) attribute in the XML, thus:

  <xsl:variable name="showIndex">
    <xsl:choose>
      <xsl:when test="book/@showIndex='no'">no</xsl:when>
      <xsl:otherwise>yes</xsl:otherwise>
    </xsl:choose>
  </xsl:variable>

You'll have to avoid generating the page sequence at the
XSLT level. One possiblity is to put a test for
the existence of the elements which provide the content
around the code which generates the page sequence.
