How to show page number (N of N) using xslt in PDF Report

Question

I am using XSLT to generate PDF report. My requirements are to display page number in the format of Page N of N (e.g.Page 1 of 3) at the footer of the report. For static values it works fine and it repeats on each page. As total number of pages in the report are not known and it changes run time, so how I will accomplish this task.

My XSLT code snippet

<xsl:template name="footerall">
<xsl:variable name="maxwidth" select="7.07000" />
<fo:static-content flow-name="xsl-region-after">
<fo:block>
<xsl:variable name="tablewidth29" select="$maxwidth * 1.00000" />
<xsl:variable name="sumcolumnwidths29" select="0.04167 + 1.56250 + 0.04167" />
<xsl:variable name="factor29">
<xsl:choose>
<xsl:when
test="$sumcolumnwidths29 &gt; 0.00000 and $sumcolumnwidths29 &gt; $tablewidth29">
<xsl:value-of select="$tablewidth29 div $sumcolumnwidths29" />
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="1.000" />
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:variable name="defaultcolumns29" select="1" />
<xsl:variable name="defaultcolumnwidth29">
<xsl:choose>
<xsl:when test="$factor29 &lt; 1.000">
<xsl:value-of select="0.000" />
</xsl:when>
<xsl:when test="$defaultcolumns29 &gt; 0">
<xsl:value-of
select="($tablewidth29 - $sumcolumnwidths29) div $defaultcolumns29" />
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="0.000" />
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:variable name="columnwidth29_0" select="$defaultcolumnwidth29" />
<xsl:variable name="columnwidth29_1" select="1.56250 * $factor29" />
<fo:table width="{$tablewidth29}in" border-collapse="separate"
border-separation="0.04167in" color="black" display-align="center">

<xsl:text>Page 1 of 1</xsl:text>
</fo:inline>
<fo:inline font-family="Courier" font-size="10px">
<xsl:value-of select="$My XPath to varaible" />
</fo:inline>
</fo:block>
</fo:table-cell>
<fo:table-cell
font-size="inherited-property-value(&apos;font-size&apos;) - 2pt"
text-align="right" padding-top="0.00000in" padding-bottom="0.00000in"
padding-left="0.00000in" padding-right="0.00000in">
<fo:block padding-top="1pt" padding-bottom="1pt" />
</fo:table-cell>
</fo:table-row>
</fo:table-body>
</fo:table>
</fo:block>
</fo:static-content>
</xsl:template>

I will replace the string (Page 1 of 1) by a variable but how to handle this.

Please help me.

Answer 1

I solved my problem by following below instructions.

Put a formatting object with an id at the end of the area. You can then do a to the labeled block that appears on the last page of the document. Here's how the markup looks:

<fo:flow flow-name="xsl-region-body">
... Lots and lots of content here
<fo:block id="TheVeryLastPage"> </fo:block>
</fo:flow>

The code creates a block with an id of TheVeryLastPage (a value that's unlikely to be used by anyone), and now you can refer to that id to get the page number of the last page of the document. Here's how the content in the area should look:

<fo:block text-align="end">
Page <fo:page-number/> of 
<fo:page-number-citation 
ref-id="TheVeryLastPage"/>
</fo:block>

When FOP formats this markup, it generates something like "Page 2 of 5".

Answer 2

You should add an id attribute to your fo:page-sequence element, and then use a page-number-citation-last.

<fo:page-sequence id="my-sequence-id">
  ...
  <xsl:text>Page </xsl:text>
  <fo:page-number-citation />
  <xsl:text> of </xsl:text>
  <fo:page-number-citation-last page-citation-strategy="all" ref-id="my-sequence-id"/>
  ...
</fo:page-sequence>

See the specs: http://www.w3.org/TR/xslfo20/#fo_page-number-citation and http://www.w3.org/TR/xslfo20/#fo_page-number-citation-last
