XSLT:读取由空标签划分的内容 [英] XSLT: Reading content that is devided by empty tags

问题描述

所以我正忙着创建一个 XSLT 文件来将各种 XML 文档处理成一个新的节点布局.

So I am busy creating a XSLT file to process various XML documents into a new node layout.

有一件事我想不通，这是我正在使用的 XML 示例:

There's one thing I can't figure out, here is an example of XML that I'm working with:

<page>
   This is a paragraph on the page.
    <newParagraph/>
   This is another paragraph.
    <newParagraph/>
   Here is yet another paragraph on this page.
<page>

如您所见，段落使用空标签作为分隔符进行分割.在结果 XML 我想要这个:

As you can see the paragraphs are split up using empty tags as deviders. In the result XML I want this:

<page>
   <p>
    This is a paragraph on the page.
   </p>
   <p> 
    This is another paragraph.
   </p>
   <p>
   Here is yet another paragraph on this page.
   </p>
<page>

如何使用 XSLT(仅限 1.0 版)实现此目的?

How can I achieve this using XSLT (Version 1.0 only)?

推荐答案

如果你愿意作弊"一点，你可以手动将 XML 标签插入到结果文档中，这些标签不是节点树的一部分而是普通文本.然而，下游处理器不会注意到差异，前提是它重新解析输出.

If you are willing to "cheat" a little bit you can manually insert XML tags into result document which are not part of the node tree but which are normal text. A processor downstream, however, will not notice the difference provided that it re-parses the output.

鉴于我的其他答案的输入，以下 XSLT 1.0 转换将起作用(保留段落中的子树):

Given the input of my other answer the following XSLT 1.0 transformation will do the trick (preserving the sub trees in the paragraphs):

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet 
    version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" />

  <xsl:template match="page">
    <page>
      <P>
        <xsl:apply-templates/>
      </P>
    </page>
  </xsl:template>

  <!-- this default rule recursively copies all substructures within a paragraph at tag level -->  
  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>


  <!-- this default rule makes sure that texts between the tags are printed -->
  <xsl:template match="text()">
    <xsl:copy-of select="."/>
  </xsl:template>

  <xsl:template match="newParagraph">
    <!-- This inserts a matching closing and opening tag -->
    <xsl:value-of select="'&lt;/P&gt;&lt;P&gt;'" disable-output-escaping="yes" />
  </xsl:template>

</xsl:stylesheet>
