问题描述

这个问题建立在对我的原始问题,有人建议我发布后续问题.这涉及尝试集成上一篇文章中的 XSL 代码.

在上一个问题中,我展示了一个简化版的 TEI:XML 文档,我正在使用 XSLT 2.0 将其转换为 HTML(完整的 tei 文件和当前的 xslt 可以在此处找到 https://xsltfiddle.liberty-development.net/bdxtqT/6).这是层次结构的更完整视图,但不是所有细节:

<teiHeader/><文本><前面/><身体><p xml:lang="LA"><seg type="typefoo" corresp="#foo601" xml:id="foo361"><date type="deposition_date" when="1245">Idusmarcii</date>在非亨德里特米图斯中.摆姿势爱神,坐在 amet pharetra lacus.</seg><seg type="typefoo" xml:id="foo362">Nullam semper variusjusto, vitae mollis turpis dapibus 坐 amet.Donecnote contentrhoncus tempor urna 坐 amet imperdiet.</seg><seg type="typefoo" xml:id="foo363">整数我是前任.Curabitur at ligula sed arcu consequat妊娠和 id orci.Morbi quis porta dolor.</seg><seg type="typefoo" corresp="#foooid2">Sed 格言<注意type="public_note">note 内容 2</note>sem nec urna sodales诅咒.Donec sat amet nibh tempor, congue ligula semper,</seg></p><返回><p xml:lang="EN"><段><段></p><p xml:lang="FR"><段><段></p><tei>

所需的 HTML 输出如下.根据以下三个条件之一在 中创建增量脚注编号:

  • date[@type="deposition_date"](添加脚注编号),

  • seg[@type="typefoo"](添加脚注编号)

  • note[@type="public_note"](替换为脚注编号).

期望的输出

 

<p>Idus marcii<sup>1</sup>在非hendrerit metus中.塞入posuere eros, 坐在 amet pharetra lacus.</p><sup>2</sup><p>Nullam semper varius justo, vitae mollis turpisdapibus 坐在 amet.Donec <sup>3</sup>颞肌</p><p>整数 id ante nunc.Curabitur at ligula sedarcu consequat gravida et id orci.莫尔比之门多洛尔.</p><p>Sed dictum sem<sup>4</sup>nec urna sodales cursus.Donec sat amet nibh tempor, congue ligula semper,</p><sup>5</sup><div>[...]<div><p><sup>1</sup>1245/p<p><sup>2</sup>foo601

<p><sup>3</sup>请注意这里

<p><sup>4</sup>请注意这里

<p><sup>5</sup>foooid2/p

完整的 XSLT 转换文档位于 https://xsltfiddle.liberty-development.net/bdxtqT/6,这里可以看到如下问题:

  • date[@type='deposition_date'] 被完全替换,而是接收添加的脚注标记
  • seg[@type='dep_event' and @corresp] 没有收到添加的脚注标记,但它出现在底部的

    页面.

XSL 文件太长,似乎无法正确粘贴到此处.在此处与文件交互 https://xsltfiddle.liberty-development.net/bdxtqT/6.

注意:我仅限于 XSLT 2.0,因为此转换是在 eXist-DB 内部使用 Xquery 3.1 触发的.

非常感谢!

解决方案

我认为,除非您想在该模板中匹配 / 的所有路径前缀为我建议存储结果的变量标记插入,将现有代码与我的建议合并的一种方法是将匹配从 / 更改为 /* 例如使用

<!-- 文本的 div --><div><!-- 拉丁语:始终存在--><h3>拉丁文</h3><xsl:apply-templates select="//tei:body//tei:p"/><!-- 英语:始终存在--><h3>英语</h3><xsl:apply-templates select="//tei:back//tei:p[@xml:lang='EN']"/><!-- 法语:有时出现--><xsl:if test="//tei:back//tei:p[@xml:lang='FR']"><h3>法语</h3><xsl:apply-templates select="//tei:back//tei:p[@xml:lang='FR']"/></xsl:if><!-- 注释页脚 --><div class="footer"><!-- 脚注(使用 mode="build_footnotes" 在 <div> 中构造脚注块)--><xsl:if test="$footnote-sources"><div class="footnotes" id="footnotesdiv"><xsl:apply-templates select="$footnote-sources" mode="build_footnotes"/>

</xsl:if>

</xsl:模板>

那就意味着我建议使用

<xsl:apply-templates select="$fn-markers- added/node()"/></xsl:模板>

可以保留并且 XSLT 处理器会应用它.

然而,在模板末尾使用了该变量 $footnote-sources,据我从片段中看到,它在原始输入文档的节点上的使用不会受引入临时结果添加标记的影响,但不知何故对我来说,在那个地方继续处理原始输入而其余部分处理临时结果是错误的,所以我倾向于将变量声明更改为

<xsl:variable name="footnote-sources" select="$fn-markers- added/tei:text//tei:seg//date[@type='deposition_date'] |$fn-markers- added/tei:text//tei:seg//note[@type='public_note'] |$fn-markers- added/tei:text//tei:seg[@corresp]"/>

通过这两个更改,我认为应该应用我在上一个答案中的建议.尽管现在再次查看带有 tei 根元素的已发布源代码,但我想知道具有以 tei:text 开头的路径的全局变量如何选择任何内容,但也许这是在样品.

This question builds on the responses to my original question, where it was suggested that I post a followup. This concerns attempting to integrate the XSL code from the previous post.

In the previous question I presented a simplified version of the TEI:XML document I am transforming into HTML using XSLT 2.0 (the full tei file and current xslt can be found here https://xsltfiddle.liberty-development.net/bdxtqT/6). This is a fuller view of the hierarchy, but not all details:

<tei>
 <teiHeader/>
 <text>
   <front/>
   <body>
     <p xml:lang="LA">
       <seg type="typefoo" corresp="#foo601" xml:id="foo361">
         <date type="deposition_date" when="1245">Idus 
         marcii</date>In non hendrerit metus. Sed in posuere 
         eros, sit amet pharetra lacus.</seg>
       <seg type="typefoo" xml:id="foo362">Nullam semper varius 
         justo, vitae mollis turpis dapibus sit amet. 
         Donec<note type="public_note">note content</note> 
         rhoncus tempor urna sit amet imperdiet.</seg>
       <seg type="typefoo" xml:id="foo363">Integer 
         id ante nunc. Curabitur at ligula sed arcu consequat 
         gravida et id orci. Morbi quis porta dolor.</seg>
       <seg type="typefoo" corresp="#fooid2">Sed dictum<note 
         type="public_note">note content 2</note> sem nec urna sodales 
         cursus. Donec sit amet nibh tempor, congue ligula semper, 
         rhoncus odio.</seg>
     </p>
   </body>
   <back>
     <p xml:lang="EN">
       <seg>
       <seg>
     </p>
     <p xml:lang="FR">
       <seg>
       <seg>
     </p>
   </back>
 </text>     
<tei>

The desired HTML output is as follows. Incremental footnote numbers are created in <sup> based on one of three conditions:

  • date[@type="deposition_date"] (add footnote no.),

  • seg[@type="typefoo"] (add footnote no.)

  • note[@type="public_note"] (replace with footnote no.).

Desired output

 <div>
   <p>Idus marcii<sup>1</sup>In non hendrerit metus. Sed in 
       posuere eros, sit amet pharetra lacus.</p><sup>2</sup>
   <p>Nullam semper varius justo, vitae mollis turpis 
       dapibus sit amet. Donec<sup>3</sup> rhoncus tempor 
       urna sit amet imperdiet.</p>
   <p>Integer id ante nunc. Curabitur at ligula sed 
       arcu consequat gravida et id orci. Morbi quis porta 
       dolor.</p>
   <p>Sed dictum sem<sup>4</sup> nec urna sodales cursus. 
      Donec sit amet nibh tempor, congue ligula semper, 
      rhoncus odio.</p><sup>5</sup>
  <div>

  [...]

 <div>
   <p><sup>1</sup> 1245</p>
   <p><sup>2</sup> foo601</p>
   <p><sup>3</sup> note here</p>
   <p><sup>4</sup> note here</p>
   <p><sup>5</sup> fooid2</p>
  </div>

The full XSLT transformation document is found at https://xsltfiddle.liberty-development.net/bdxtqT/6, where one can see the following problems:

  • date[@type='deposition_date'] is being entirely replaced, instead receiving an added footnote marker
  • seg[@type='dep_event' and @corresp] is not receiving an added footnote marker, but it appears in the <div> at the bottom of the page.

The XSL file is too long and doesn't seem to paste here correctly. Interact with files here https://xsltfiddle.liberty-development.net/bdxtqT/6.

NB: I am restricted to XSLT 2.0 as this transformation is fired off inside eXist-DB with Xquery 3.1.

Thanks very much!

解决方案

I think, unless you want to prefix all your paths in that template matching / with the variable I suggested to store the result of the marker insertion, one way to merge the existing code with my suggestion is to change the match from / to /* e.g. use

<xsl:template match="/*">
        <!-- div for text -->
        <div>
            <!-- LATIN : always present -->
            <h3>Latin</h3>
            <xsl:apply-templates select="//tei:body//tei:p"/>

            <!-- ENGLISH : always present -->
            <h3>English</h3>
            <xsl:apply-templates select="//tei:back//tei:p[@xml:lang='EN']"/>

            <!-- FRENCH : sometimes present -->
            <xsl:if test="//tei:back//tei:p[@xml:lang='FR']">
                <h3>French</h3>
                <xsl:apply-templates select="//tei:back//tei:p[@xml:lang='FR']"/>
            </xsl:if>
            <!-- FOOTER for notes -->
            <div class="footer">

            <!-- FOOTNOTES (uses mode="build_footnotes" to construct a block of footnotes in <div>) -->
               <xsl:if test="$footnote-sources">
                 <div class="footnotes" id="footnotesdiv">
                     <xsl:apply-templates select="$footnote-sources" mode="build_footnotes"/>
                 </div>
               </xsl:if>
            </div>
        </div>
</xsl:template>

that would then mean that my suggestion to use

<xsl:template match="/">
    <xsl:apply-templates select="$fn-markers-added/node()"/>
</xsl:template>

can be kept and the XSLT processor would apply it.

There is however the use of that variable $footnote-sources at the end of the template, as far as I can see from the snippet its use on nodes from the original input document would not be affected by the introduction of a temporary result adding markers but somehow to me it would feel wrong to at that place keep processing the original input while the rest works on the temporary result so I would be inclined to change the variable declaration to

<xsl:variable name="footnote-sources" select="$fn-markers-added/tei:text//tei:seg//date[@type='deposition_date'] | 
    $fn-markers-added/tei:text//tei:seg//note[@type='public_note'] | $fn-markers-added/tei:text//tei:seg[@corresp]"/>

With those two changes I think my suggestion in the previous answer should then be applied. Although now looking again at the posted source with a tei root element I wonder how a global variable having paths starting with tei:text would select anything but perhaps that is an omission in the sample.
