我在命令行中使用 Docbook 1.78 和 xsltproc(libxslt 1.1.26 和 libxml 2.7.8)从 XML 文件生成 fo 文件。我的目标是使用 Apache 格式的输出处理器(fop;1.1 版)生成 PDF。我的 XML 输入文件:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE book SYSTEM "http://www.oasis-open.org/docbook/xml/4.4/docbookx.dtd">
<book lang="de" id="MyBook">
    <chapter id="Introduction">
        <title>Introduction</title>
        <section id="sec_intro_1">
            <title>Test</title>
            <para>para1_sec_intro_1 (see also glossary: <xref linkend="gloss_etm-datei"/>).</para>
            <para>para2_sec_intro_1</para>
        </section>
        <section id="sec_intro_2">
            <title>Another Test</title>
            <para>para1_sec_intro_2 (glossary: <xref linkend="gloss_etm-datei"/>).</para> 
            <para>para2_sec_intro2</para>       
        </section>
    </chapter>
    <xi:include href="glossar_test.xml" xmlns:xi="http://www.w3.org/2001/XInclude"></xi:include>
</book>

如果我运行以下命令

xsltproc -o ./test.fo --xinclude --stringparam paper.type A4 --stringparam fop1.extensions 1 ./docbook/fo/docbook.xsl ./test.xml 2> fo_out.txt

生成了 fo 文件,但它包含 fo:wrapper 元素,其 ID 不是唯一的。这是生成的 fo 文件:

...
(see also glossary: <fo:basic-link internal-destination="gloss_etm-datei"><fo:inline>
            <fo:wrapper id="idp8751564240"><!--ETM-Datei--></fo:wrapper>
            <fo:inline font-weight="bold">ETM-Datei</fo:inline>
        </fo:inline></fo:basic-link>)
....
(glossary: <fo:basic-link internal-destination="gloss_etm-datei"><fo:inline>
            <fo:wrapper id="idp8751564240"><!--ETM-Datei--></fo:wrapper>
            <fo:inline font-weight="bold">ETM-Datei</fo:inline>
        </fo:inline></fo:basic-link>).
...

现在,如果我尝试从该 fo 文件生成 pdf 文件,fop 会引发异常:

我在这里做错什么了吗?我很感激任何帮助!

提前致谢!

我找到了解决方案!在http://www.sagehill.net/docbookxsl/LinkToGlossary.html描述了如何引用词汇表。通常,您会使用glossterm-tag,例如:

<para>Set your <glossterm linkend="NetAddr">network address</glossterm>.
</para>
...
<glossary>
  <glossentry id="NetAddr">
    <glossterm>Network address</glossterm>
    <glossdef><para>Four numbers separated by periods</para></glossdef>
  </glossentry>
</glossary>

您也可以使用linkor xref-tag。如果您使用外部参照标签,您必须将一个id属性添加到glossterm 并将一个匹配的endterm 属性添加到xref元素。例如:

<xref linkend="ge-xslfoprocessor" endterm="gt-xslfoprocessor"/>
...

<glossentry id="ge-xslfoprocessor">
<glossterm id="gt-xslfoprocessor">XSL-FO processor</glossterm>
<glossdef>
<para>Software component that converts an XSL-FO document into a
formatted document.</para>
</glossdef>
</glossentry>

如果这样做,fo:wrapper 的 id 将被删除,并且 fop 可以将其解析为 pdf 文件。
