下面是一个关于如何在每个页面上获取页眉和页脚的简单示例。希望这可以帮助

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
    <fo:layout-master-set>
        <fo:simple-page-master master-name="simple" page-height="11in" page-width="8.5in" margin-top=".5in" margin-bottom=".5in" margin-left=".5in" margin-right=".5in">
            <fo:region-body region-name="xsl-region-body" margin-bottom=".5in" margin-top=".50in"/>
            <fo:region-before region-name="xsl-region-before" extent="5in"/>
            <fo:region-after region-name="xsl-region-after" extent=".5in"/>
        </fo:simple-page-master>
    </fo:layout-master-set>
    <fo:page-sequence master-reference="simple">

            Body

            <fo:block>
            Body

If you want header and footer, don't put them into the fo:flowelement. They belong into <fo:static-content flow-name="your_flow">where your_flowcan be xsl-region-beforeor xsl-region-afteror any other name you like to give.

如果您想要页眉和页脚，请不要将它们放入fo:flow元素中。它们属于<fo:static-content flow-name="your_flow">where your_flowcan bexsl-region-before或xsl-region-after您喜欢的任何其他名称。

This leads to the missing definition of your regions. The ones you use are not defined. Make this work like <fo:region-body region-name="xsl-region-body">or <fo:region-before region-name="xsl-region-before">

这会导致您的区域缺少定义。你使用的那些没有定义。使这项工作像<fo:region-body region-name="xsl-region-body">或<fo:region-before region-name="xsl-region-before">

I didn't check if something else prevents the script from working, but your question should be answered with this.

我没有检查是否有其他原因阻止脚本工作，但您的问题应该用这个来回答。

Use this in an itemstyle to output a header:

在 itemstyle 中使用它来输出标题：

<xsl:if test="count(preceding-sibling::*)=0">
</xsl:if>

Use this in an itemstyle to output a footer:

在 itemstyle 中使用它来输出页脚：

<xsl:if test="count(following-sibling::*)=0">
</xsl:if>
