使用 Apache FOP 从 XML 文件开始从 XSL-FO 转换为 PDF

Question

I'm new to XSL-FO programming and I need help. I basically need to render a XSL-FO file into PDF with data from XML.

But when I try, everything appears right int the PDF (background, manually entered text) but not data that should be read from XML.

Notice that I tried only with the element "idShip".

My XML file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE shipment SYSTEM "C:\Users\informatica\Documents\workspace\PrintTest\shipment.dtd">
<?xml-stylesheet href="shipment_to_pdf.xsl" ?>

<shipment>
    <idShip>111</idShip>
    <fare></fare>
    <to>
        <name></name>
        <surname></surname>
        <address1></address1>
        <address2></address2>
        <zip></zip>
        <city></city>
        <country></country>
        <email></email>
        <phone></phone>
    </to>
    <from>
        <name></name>
        <surname></surname>
    </from>
</shipment>

XSL:

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <fo:layout-master-set>
                <fo:simple-page-master page-height="135mm"
                    page-width="216mm" margin-top="10mm" margin-left="20mm"
                    margin-right="20mm" margin-bottom="10mm" master-name="PageMaster">
                    <fo:region-body background-color="#EFAFAF"
                        margin-top="20mm" margin-left="10mm" margin-right="10mm"
                        margin-bottom="20mm" />

                </fo:simple-page-master>
            </fo:layout-master-set>
            <fo:page-sequence initial-page-number="1"
                master-reference="PageMaster">
                <fo:flow flow-name="xsl-region-body">
                    <fo:block text-indent="1em" font-family="sans-serif"
                        font-size="20pt" font-weight="bold" background-color="#EEEEEE"
                        line-height="20mm">

                        //this should be the problem 
                        <xsl:for-each select="shipment">
                            <xsl:value-of select="idShip" />
                        </xsl:for-each>

                     </fo:block>
                </fo:flow>


            </fo:page-sequence>     
</fo:root>

PDF right now renders as a block with a red background, but no data from XML.

Answer 1

You are using a so-called simplified XSLT module ( XSLT 1.1 recommendation , XSLT 2.0 recommendation ) which is almost correct, it is only missing the xsl:version attribute in the root element.

Just add xsl:version="1.0" (or 2.0 if you need the new features and your XSLT processor supports them) to the fo:root element and you should get the expected result.

Note that a simplified stylesheet has some limitations, as you cannot define parameters, global variables, functions (if using XSLT 2.0), keys and other templates.
