匹配以下内容并调用模板 [英] matching the following and call template

问题描述

这是一个简化的XML，它暴露了我所遇到的问题的一般结构.

This is a simplified XML which exposes the general structure of the problem I have.

<chapter num="07">
    <title>
        <page num="703"/>
        ... text (mixed content) ...
    </title>

    <page num="704"/>
    <section level="sect1">
        <title>...text...</title>
        <para num="7.1.1">... a lot of text (mixed content)...</para>
    </section>
    <section level="sect1">
        <title>... text... </title>
        <para num="7.2.1">Some text...
            <footnoteref linkend="fn3" num="3"/>
            <footnote num="3" id="fn3"> ... mixed content ...</footnote> 
            ...more text...
        </para>

        <page num="705"/>
        <section level="sect2">
            <title>...</title>
            <para num="7.2.2">... text ...
                <footnoteref linkend="fn4" num="4"/>
                <footnote num="4" id="fn4">...</footnote> 
                ... more text ...
                <footnoteref linkend="fn5" num="5"/>
                <footnote num="5" id="fn5">...</footnote> 
                ... more text ...
            </para>
            <para num="7.2.5">...

                <page num="706"/>... 

                <footnoteref linkend="fn6" num="6"/>
                <footnote num="6" id="fn6"> ... </footnote>
            </para>
            <para num="7.2.6">... some text
                <footnoteref linkend="fn7" num="7"/>
                <footnote num="7" id="fn7"> ... </footnote>  
            </para>
        </section>
    </section>
</chapter>

我必须在第一个<footnote>之前的最后一个<page>之前放置一个处理指令<?pb label=' 页码 '?> .它应该只出现一次，并且页码应该与出现的最后一个<page>元素的num属性中的值相同.

I have to place one processing instruction <?pb label='page number'?> before the first <footnote> matching the last preceding <page>. It should appear only once and the page number should be the same as the value in the num attribute of the last <page> element that appeared.

例如，如果我处理上述源代码，我希望在结果文档 one <?pb label='704'?>中紧接在<footnote num="3">之前， one <?pb label='705'?>中生成在<footnote num="4">之前(将脚注4和5分组)，以及在<footnote num="6">之前的 one <?pb label='706'?>(将脚注6和7分组).有一个用于处理<footnote>元素的模板，它们被放置在每页的末尾，并带有处理指令(<footnoteref>元素保留在它们所在的位置).

For example, if I process the source above, I expect to generate in my result document one <?pb label='704'?> immediately before <footnote num="3">, one <?pb label='705'?> immediately before <footnote num="4"> (grouping footnotes 4 and 5), and one <?pb label='706'?> immediately before <footnote num="6"> (grouping footnotes 6 and 7). There is a template to process the <footnote> elements and they are placed together at the end of each page, preceded by the processing instruction (the <footnoteref> elements stay where they are).

我的XSL在此处.由于太大，我无法将其粘贴到这里.

My XSL is here. Since it is too big, I'm unable to paste it here.

我在脚注处理说明(pb标签)中得到了重复.仅在最后一个page标记之后的第一个footnote之前应该有一个pblabel.我尝试与preceding::page匹配，但是没有用.相同的处理指令被重复多次.例如:<?pb label='706'?>应该仅在footnote 6上方出现一次，因为它是page 706之后的第一个footnote.

I'm getting duplicates in the footnote processing instructions (the pb labels). There should be a pblabel only before the first footnote following the last page tag. I tried matching with preceding::page but it didn't work. The the same processing instruction is being repeated multiple times. For example: <?pb label='706'?> should appear only once above footnote 6 because it is the first footnote following page 706.

推荐答案

不进行费时的分析就很难分辨，但是请尝试更改此xsl:if(在match="footnote" mode="footnote"中):

It's hard to tell without doing a time consuming analysis, but try changing this xsl:if (in match="footnote" mode="footnote"):

    <xsl:if test="preceding::node()[page[1]]">
        <xsl:variable name="op">&#60;</xsl:variable>
        <xsl:variable name="apos">'</xsl:variable>
        <xsl:variable name="cl">&#62;</xsl:variable>

        <xsl:value-of select="concat($op,'?pb label=',$apos,preceding::page[1]/@num,$apos,'?',$cl)"/>

    </xsl:if>

对此:

    <xsl:if test="(preceding::page|preceding::footnote)[last()][self::page]">
        <xsl:processing-instruction name="pb" select="concat('label=''',preceding::page[1]/@num,'''?')"/>
    </xsl:if>

Kinda感到奇怪的是，当您的输出方法是HTML(具有SGML处理指令)时，您试图输出XML处理指令.

Kinda strange that you're trying to output XML processing instructions when your output method is HTML (which would have SGML processing instructions).
