xsl fo 永远找不到 page-position "first"

Question

我正在使用 Apache Fop (2.1) 从 XML 生成 RTF 文档。我希望第一页的标题与其他页面的标题不同。我设置了两个simple-page-masters，一个用于第一页，一个用于其他页面。我运行在进入页面位置 "first" 时遇到了问题。它永远不会到达那里：

<fo:page-sequence-master master-name="my-sequence">
        <fo:repeatable-page-master-alternatives>
            <fo:conditional-page-master-reference page-position="first" master-reference="firstPage"/>
            <fo:conditional-page-master-reference page-position="rest" master-reference="otherPage"/>
        </fo:repeatable-page-master-alternatives>
    </fo:page-sequence-master>

它总是到达 page-position="rest"，即使是文档的第一页。谁能告诉我为什么？我该如何解决这个问题？

Fop 确实给我这个错误：

Only simple-page-masters are supported on page-sequences. Using default simple-page-master from page-sequence-master "my-sequence"

这是我的 xslt 的其余部分：

<fo:layout-master-set>
    <fo:simple-page-master master-name="firstPage"
        page-height="11in" page-width="8.5in"
        margin-top=".5in" margin-left="1in" margin-right="1in" margin-bottom=".5in">

        <fo:region-body />
        <fo:region-before region-name="firstPageBefore"/>
    </fo:simple-page-master>

    <fo:simple-page-master master-name="otherPage"
        page-height="11in" page-width="8.5in"
        margin-top=".5in" margin-left="1in" margin-right="1in" margin-bottom=".5in">

        <fo:region-body />
        <fo:region-before region-name="otherPageBefore"/>
    </fo:simple-page-master>

    <fo:page-sequence-master master-name="my-sequence">
        <fo:repeatable-page-master-alternatives>
            <fo:conditional-page-master-reference page-position="first" master-reference="firstPage"/>
            <fo:conditional-page-master-reference page-position="rest" master-reference="otherPage"/>
        </fo:repeatable-page-master-alternatives>
    </fo:page-sequence-master>
</fo:layout-master-set>

<fo:page-sequence master-reference="my-sequence">

    <fo:static-content flow-name="firstPageBefore">
        <fo:block>First page!</fo:block>
    </fo:static-content>

    <fo:static-content flow-name="otherPageBefore">
        <fo:block>Other page!</fo:block>
    </fo:static-content>

    <fo:flow flow-name="xsl-region-body" >
        <xsl:apply-templates/>
    </fo:flow>

</fo:page-sequence>

Answer 1

我使用这个示例：

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
    <fo:layout-master-set>
        <fo:simple-page-master master-name="firstPage"
            page-height="11in" page-width="8.5in"
            margin-top=".5in" margin-left="1in" margin-right="1in" margin-bottom=".5in">
            <fo:region-body background-color="red"/>
            <fo:region-before region-name="firstPageBefore"/>
        </fo:simple-page-master>
        <fo:simple-page-master master-name="otherPage"
            page-height="11in" page-width="8.5in"
            margin-top=".5in" margin-left="1in" margin-right="1in" margin-bottom=".5in">
            <fo:region-body />
            <fo:region-before region-name="otherPageBefore"/>
        </fo:simple-page-master>
        <fo:page-sequence-master master-name="my-sequence">
            <fo:repeatable-page-master-alternatives>
                <fo:conditional-page-master-reference page-position="first" master-reference="firstPage"/>
                <fo:conditional-page-master-reference page-position="rest" master-reference="otherPage"/>
            </fo:repeatable-page-master-alternatives>
        </fo:page-sequence-master>
    </fo:layout-master-set>
    <fo:page-sequence master-reference="my-sequence">
        <fo:flow flow-name="xsl-region-body" >
            <fo:block break-after="page">First Page</fo:block>
            <fo:block break-after="page">Second Page</fo:block>
            <fo:block break-after="page">Third Page</fo:block>
            <fo:block>Forth Page</fo:block>
        </fo:flow>
    </fo:page-sequence>
</fo:root>

请注意，我只将第一页的背景设为红色 "region-body"。我用 Apache FOP 2.1 得到这个输出：

现在，如果我只将格式更改为 RTF 而不是 PDF，则无法获得预期的输出。如果事实上为了测试这一点，我什至将第一页的大小更改为 5inx5in。如果我检查生成的 RTF，只有最后一个页面布局。

为了证明这一点，我将第一页更改为 5x5，将其余页面更改为 11x8.5 横向，原始 RTF 显示如下：

{*\generator Apache XML 图形 RTF 库；} \fet0 \ftnbj \paperw15840 \paperh12240 \landscape \margt720 \margb720 \margl1440 \margr1440 \headery720 \footery720 \itap0

这只是一个页面模板，不是第一个模板。见下图，所有页面都是横向的，根本没有应用任何颜色。

这似乎是 Apache FOP RTF 输出的错误或不受支持的功能。
