My xml is root with many different child element in any order, each with its own markup inside page-sequence. Xslt template takes one param - initial page of this document. And I cant set it in initial-page-number attribute for page-sequence because dont know which element will be first. Is there any workarounds in xsl-fo or xslt level for applying given number as page number of first page-sequence?
xml example 1:
<root>
<item-abc/>
<item-def/>
<item-ghj/>
</root>
xml example 2:
<root>
<item-ghj/>
<item-ghj/>
<item-abc/>
</root>
xslt:
<x:stylesheet version="1.0" xmlns:x="http://www.w3.org/1999/XSL/Transform">
<x:template match="/">
<fo:root text-align="center" font-family="Arial" font-size="9pt">
<fo:layout-master-set>
<fo:simple-page-master master-name="m" margin-left="7mm" margin-right="9mm" margin-top="8mm" margin-bottom="1mm" page-width="210mm" page-height="297mm">
<fo:region-body margin-top="14mm" margin-left="2mm"/>
<fo:region-before />
<fo:region-after />
</fo:simple-page-master>
</fo:layout-master-set>
<x:apply-templates select="root/item-abc"/>
<x:apply-templates select="root/item-def"/>
<x:apply-templates select="root/item-ghj"/>
</fo:root>
</x:template>
<x:template match="root/item-abc">
<fo:page-sequence master-reference="m" format="00001">
....
</fo:page-sequence>
</x:template>
...another items' templates
</x:stylesheet>
because dont know which element will be first.
If it is true, change the follwoing your code
<x:apply-templates select="root/item-abc"/>
<x:apply-templates select="root/item-def"/>
<x:apply-templates select="root/item-ghj"/>
to
<x:apply-templates select="root/*"/>
And check which is first by position() function:
<x:template match="root/item-abc">
<fo:page-sequence master-reference="m" format="00001">
<x:if test="position() eq 1">
<x:attribute name="initial-page-number" select="'1'"/>
</x:if>
....
</fo:page-sequence>
</x:template>
This will satisfy your requirement.
