Problem generating PDF with FOP 0.94
Hi All,
I'm a newbie when it comes to using XSL and FOP to generate PDF's. I
inherited a print output program from another programmer and there has
been no documentation on how the printing or layouts are configured.
I've had to learn XSL/XSLT and the FOP and thus far I've managed to get
a .fo file generated for the layout I want, except that I end up with a
double <fo:root> element in the FO file.
My partial XSL looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:decimal-format name="invoice" decimal-separator="."
grouping-separator="," infinity="" minus-sign="-" NaN="" percent="%"
per-mille="m" zero-digit="0" digit="#" pattern-separator=";"/>
<xsl:key name="htt" match="hospital_item" use="@tariff_type"/>
<xsl:template match="printspecification">
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>
<fo:simple-page-master master-name="main" margin="1cm"
page-width="29.7cm" page-height="21cm">
<fo:region-body margin="1cm 0cm 1cm 0cm"/>
<fo:region-before extent="1cm"/>
<fo:region-after extent="1cm"/>
</fo:simple-page-master>
</fo:layout-master-set>
<xsl:apply-templates select="batch" />
<xsl:apply-templates />

<fo:flow flow-name="xsl-region-body">
<xsl:apply-templates select="invoice"/>
</fo:flow>
</fo:page-sequence>
</xsl:template>
.
.
. -- Several other templates follow here before the file is closed off.
</xsl:stylesheet>
It's processed with xsltproc into the fo file.
I have been experiencing difficulty with the call to the "batch"
template in the <fo:root> section of the "printspecification" template.
If I leave off the <xsl:apply-templates /> tag, then I only get the
<fo:root><fo:layout-master> tag set in the output .fo file, like so:
<?xml version="1.0"?>
<fo:root
xmlns:fo="http://www.w3.org/1999/XSL/Format"><fo:layout-master-set><fo:s
imple-page-master master-name="main" margin="1cm" page-width="29.7cm"
page-height="21cm"><fo:region-body margin="1cm 0cm 1cm 0cm"
/><fo:region-before extent="1cm"/><fo:region-after
extent="1cm"/></fo:simple-page-master></fo:layout-master-set></fo:root>
but with the apply-templates tag, I get the rest of the template content
(and extracted data) from the XML file. Except, I end up with two
<fo:root> elements...
Here is the top part of the .fo file:
<?xml version="1.0"?>
<fo:root
xmlns:fo="http://www.w3.org/1999/XSL/Format"><fo:layout-master-set><fo:s

(I've cut the last part from this output since it all appears correct.
Except for the dual fo:root tag sets that prevents the FOP from
generating a valid/any PDF file for me.)
<<200608081650+111.fo>> <<print_layout.xsl>>
I've attached the XSL file and the produced .fo file since Microsoft
might be applying formatting to the text that makes my email hard to
read.
Any help and advise that you can offer would be greatly appreciated.
Thanks.

Does your XML input contain 2 printspecification elements? I would guess
that is the most likely reason you end up with 2 fo:root nodes in the FO
file?
