xsl-fo：并行的两份报告，一份在奇数页，另一份在偶数页

我想生成一个 PDF，其中一个内容流在奇数页，另一个内容流在偶数页，因此当您双面打印 PDF 时，您有一个模板可以在偶数页上写笔记。这是我所拥有的，但它不起作用：

    <?xml version="1.0" encoding="UTF-8"?> 
    <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
        <fo:layout-master-set>
            <!-- Odd Pages -->
            <fo:simple-page-master master-name="odd" page-height="297mm" page-width="210mm" margin-left="2mm" margin-right="2mm">
                <fo:region-body region-name="body-odd" margin-top="118mm" margin-bottom="50mm"/>
                <fo:region-before region-name="headerodd" extent="116mm"/>
                <fo:region-after region-name="footerodd" extent="48mm"/>
            </fo:simple-page-master>

            <!-- Even Pages -->
            <fo:simple-page-master master-name="even" page-height="297mm" page-width="210mm" margin-left="2mm" margin-right="2mm">
                <fo:region-body region-name="body-even" margin-top="118mm" margin-bottom="50mm"/>
                <fo:region-before region-name="headereven" extent="116mm"/>
                <fo:region-after region-name="footereven" extent="48mm"/>
            </fo:simple-page-master>

            <fo:page-sequence-master master-name="A4">
                <fo:repeatable-page-master-alternatives>
                    <fo:conditional-page-master-reference master-reference="odd" blank-or-not-blank="any" odd-or-even="odd"/>
                    <fo:conditional-page-master-reference master-reference="even" blank-or-not-blank="any" odd-or-even="even"/>
                </fo:repeatable-page-master-alternatives>
            </fo:page-sequence-master>
        </fo:layout-master-set>

        <fo:page-sequence master-reference="A4">
            <fo:flow flow-name="body-odd">
                <fo:block page-break-after="always">
                    This is an ODD page. Front-page report 1.
                </fo:block>
                <fo:block page-break-after="always">
                    This is an ODD page. Front-page report 1.
                </fo:block>
                <fo:block page-break-after="always">
                    This is an ODD page. Front-page report 1.
                </fo:block>
            </fo:flow>
        </fo:page-sequence>

        <fo:page-sequence master-reference="A4">
            <fo:flow flow-name="body-even">
                <fo:block page-break-after="always">
                    This is an EVEN page. Back-page report 2
                </fo:block>
                <fo:block page-break-after="always">
                    This is an EVEN page. Back-page report 2
                </fo:block>
                <fo:block page-break-after="always">
                    This is an EVEN page. Back-page report 2
                </fo:block>
            </fo:flow>
        </fo:page-sequence>

    </fo:root>

将笔记页面的静态内容放在fo:static-content这是针对fo:region-before偶数页（或任何其他外部区域）：

<fo:page-sequence master-reference="A4">
  <fo:static-content flow-name="headereven">
    <fo:block>
      This is an EVEN page. Back-page report 2
    </fo:block>
  </fo:static-content>
  <fo:flow flow-name="body-odd">
    <fo:block page-break-after="always">
      This is an ODD page. Front-page report 1.
    </fo:block>
    <fo:block page-break-after="always">
      This is an ODD page. Front-page report 1.
    </fo:block>
    <fo:block page-break-after="always">
      This is an ODD page. Front-page report 1.
    </fo:block>
  </fo:flow>
</fo:page-sequence>

这样，您就不需要拥有与实际内容相匹配的确切页数的值得关注的内容。

您可以定位内容，使其显示在页面上的正确位置。如果您将静态内容定向到fo:region-before，您不必担心使用正确的范围，因为默认情况下溢出该区域的任何内容都将保持可见。
