Question

我有一些强大的书籍样式表。目前，我无法弄清楚问题出在哪里。我的样式表有时会起作用，有时候不起作用，这取决于TOC的长度，我可以根据我想要包含在其中的级别动态地改变它。

我的样式表以这种方式工作（我的意图是）：

让 Imprints 部分在 Title-Page 上开始，在偶数页上结束，如果TOC的最后一页是奇数，则在那之后放一个空白页它：

        <fo:page-sequence-master master-name="Imprints">
            <fo:repeatable-page-master-alternatives>
                <fo:conditional-page-master-reference master-reference="PageMaster.Blank" blank-or-not-blank="blank" page-position="any"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Title-Page" odd-or-even="odd" page-position="first"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.CopyRight-Page" odd-or-even="even" page-position="rest"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.TOC" odd-or-even="odd" page-position="rest"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.TOC" odd-or-even="even" page-position="rest"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.TOC" odd-or-even="odd" page-position="last"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.TOC" odd-or-even="even" page-position="last"/>
            </fo:repeatable-page-master-alternatives>
        </fo:page-sequence-master>

让主要部分 Content-Pages 从TOC之后的第一个奇数页（或其后的空白页）开始，让每一章从前一章之后的奇数页开始（最后一页或空白）并以偶数页结束。如果最后一页应该是奇数，强制一个空白页面（这里我想可能是问题，因为我使用整个部分以及特定的章节）：

        <fo:page-sequence-master master-name="Content-Pages">
            <fo:repeatable-page-master-alternatives>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Right.First" odd-or-even="odd" page-position="first"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Blank" blank-or-not-blank="blank" page-position="any"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Left" odd-or-even="even" page-position="rest"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Right" odd-or-even="odd" page-position="rest"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Left" odd-or-even="even" page-position="last"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Right" odd-or-even="odd" page-position="last"/>
            </fo:repeatable-page-master-alternatives>
        </fo:page-sequence-master>

我这样打电话给他们（我不确定force-page-count="even"和force-page-count="end-on-even"之间有什么区别。我查了一些文档，但我仍然不清楚）：

    <fo:page-sequence master-reference="Imprints" force-page-count="even">
        <fo:flow flow-name="xsl-region-body">
            <fo:block>
                <xsl:apply-templates select="//tei:TEI/tei:teiHeader" mode="draft"/>
            </fo:block>
        </fo:flow>
    </fo:page-sequence>
    <fo:page-sequence master-reference="PageMaster.CopyRight-Page">
        <fo:flow flow-name="xsl-region-body">
            <fo:block xsl:use-attribute-sets="p">
                © Copyright!
            </fo:block>
        </fo:flow>
    </fo:page-sequence>
    <fo:page-sequence master-reference="PageMaster.TOC">
        <fo:flow flow-name="xsl-region-body">
            <fo:block>
                <xsl:apply-templates select="//tei:TEI/tei:text" mode="toc"/>
            </fo:block>
        </fo:flow>
    </fo:page-sequence>
    <xsl:for-each select="//tei:div[@n='1']">
        <fo:page-sequence master-reference="Content-Pages" force-page-count="end-on-even">
            <fo:static-content flow-name="Region-Before-Left">
                <fo:block xsl:use-attribute-sets="running-header-left">
                    <fo:inline xsl:use-attribute-sets="running-header-pageno-left">
                        <fo:page-number/>
                    </fo:inline>
                </fo:block>
            </fo:static-content><!-- Running header right -->
            <fo:static-content flow-name="Region-Before-Right">
                <fo:block xsl:use-attribute-sets="running-header-right">
                    <fo:inline xsl:use-attribute-sets="running-header-pageno-right">
                        <fo:page-number/>
                    </fo:inline>
                </fo:block>
            </fo:static-content>
            <fo:static-content flow-name="xsl-footnote-separator">
                <fo:block>
                    <fo:leader xsl:use-attribute-sets="footnote-separator"/>
                </fo:block>
            </fo:static-content>
            <fo:flow flow-name="xsl-region-body">
                <xsl:apply-templates select="."/>
            </fo:flow>
        </fo:page-sequence>
    </xsl:for-each>

如果它失败并抛出Subsequences exhausted in page-sequence-master "Content-Pages", cannot recover. (No context info available)，则有助于更改force-page-count或向PageMaster.Page-Right.First添加另一个引用，并使其可以在even个页面上生效。有些章节有时会从奇数页开始，但有页码（不应该这样）。真的很混乱。

甚至添加：

<fo:conditional-page-master-reference master-reference="PageMaster.Page-Right.First" odd-or-even="odd" page-position="rest"/>

......没有帮助。

我使用最后一个Saxon HE和Apache FOP 1.1。

更新

根据@Tony_Graham的进展：

        <fo:page-sequence-master master-name="Imprints">
            <fo:repeatable-page-master-alternatives>
                <fo:conditional-page-master-reference master-reference="PageMaster.Title-Page" odd-or-even="odd" page-position="first"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.CopyRight-Page" odd-or-even="even" page-position="rest"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.TOC"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Blank" blank-or-not-blank="blank"/>
            </fo:repeatable-page-master-alternatives>
        </fo:page-sequence-master>
        <fo:page-sequence-master master-name="Content-Pages">
            <fo:repeatable-page-master-alternatives>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Right.First" odd-or-even="odd" page-position="first"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Left" odd-or-even="even" page-position="rest"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Right" odd-or-even="odd" page-position="rest"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Left" odd-or-even="even" page-position="last"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Page-Right" odd-or-even="odd" page-position="last"/>
                <fo:conditional-page-master-reference master-reference="PageMaster.Blank" blank-or-not-blank="blank"/>
            </fo:repeatable-page-master-alternatives>

其余的：

<fo:page-sequence master-reference="Imprints" force-page-count="end-on-even">
...

<fo:page-sequence master-reference="PageMaster.CopyRight-Page" initial-page-number="auto-odd">
...

Answer 1

将force-page-count="end-on-even"放在fo:page-sequence 之前每个要在奇数页面上开始的fo:page-sequence。或者，在initial-page-number="auto-odd"上设置fo:page-sequence。见https://www.w3.org/TR/xsl11/#initial-page-number

force-page-count="even"表示如果页面序列在偶数页面上开始，则它将在奇数页面上结束以使其成为偶数页面，反之亦然，如果它在奇数页面上开始。无论页面序列是在奇数页还是偶数页上开始，force-page-count="end-on-even"都会在奇数页上完成。（AH Formatter的扩展名以'double-even'结尾，除此之外，还强制整个文档的页数在偶数页上结束，等等。请参阅https://www.antennahouse.com/product/ahf63/ahf-ext.html#axf.force-page-count）但是，很可能{ {1}}会做你需要的。

此外：

您无需使用两个不同的initial-page-number重复fo:conditional-page-master-reference来选择相同的网页母版。这与odd-or-even一个fo:conditional-page-master-reference相同，因为默认值为odd-or-even。见https://www.w3.org/TR/xsl11/#odd-or-even。
您可以删除显式any，因为这是默认值。
“Imprints”有两个'odd-or-even =“even”page-position =“rest”'，所以第二个永远不会被使用。
为奇数/偶数和休息/最后选择相同的“PageMaster.TOC”可以简化为page-position="any"。

<强>更新

您可以将当前page-position="any"更改为：

fo:page-sequence-master

在<fo:page-sequence-master master-name="Imprints"> <fo:repeatable-page-master-alternatives> <fo:conditional-page-master-reference master-reference="PageMaster.Blank" blank-or-not-blank="blank"/> <fo:conditional-page-master-reference master-reference="PageMaster.Title-Page" page-position="first"/> <fo:conditional-page-master-reference master-reference="PageMaster.CopyRight-Page" odd-or-even="even" page-position="rest"/> <fo:conditional-page-master-reference master-reference="PageMaster.TOC"/> </fo:repeatable-page-master-alternatives> </fo:page-sequence-master> <fo:page-sequence-master master-name="Content-Pages"> <fo:repeatable-page-master-alternatives> <fo:conditional-page-master-reference master-reference="PageMaster.Blank" blank-or-not-blank="blank"/> <fo:conditional-page-master-reference master-reference="PageMaster.Page-Right.First" page-position="first"/> <fo:conditional-page-master-reference master-reference="PageMaster.Page-Left" odd-or-even="even"/> <fo:conditional-page-master-reference master-reference="PageMaster.Page-Right" odd-or-even="odd"/> </fo:repeatable-page-master-alternatives>内，“从孩子序列开始按顺序测试条件”，因此您希望首先放置最不可能的替代品。（参见https://www.w3.org/TR/xsl11/#fo_repeatable-page-master-alternatives）你也想在最后有一个全能的选择，但你已经覆盖了它。

但是，当版权页面和ToC分别位于引用特定页面主页的单独页面序列中时，我不明白为什么“Imprints”包括“PageMaster.CopyRight-Page”和“PageMaster.TOC”。你可能想要更像的东西：

fo:repeatable-page-master-alternatives

XSL-FO页面主机替代方案有时会耗尽
