混合内容和字符串操作清理

标签： xml xslt xslt-2.0

我正处于将基于Word的文档转换为XML的非常痛苦的过程中。我遇到了以下问题：

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <p>
        <element>This one is taken care of.</element> Some more text. „<hi rend="italics">Is this a
            quote</hi>?” (Source). </p>

    <p>
        <element>This one is taken care of.</element> Some more text. „<hi rend="italics">This is a
            quote</hi>” (Source). </p>

    <p>
        <element>This one is taken care of.</element> Some more text. „<hi rend="italics">This is
            definitely a quote</hi>!” (Source). </p>

    <p>
        <element>This one is taken care of.</element> Some more text.„<hi rend="italics">This is a
            first quote</hi>” (Source). „<hi rend="italics">Sometimes there is a second quote as
            well</hi>!?” (Source). </p>

</root>

<p>个节点包含混合内容。 <element>我在之前的迭代中已经处理过了。但现在问题在于引号和来源部分出现在<hi rend= "italics"/>内，部分出现在文本节点中。

如何使用XSLT 2.0：

  1. 匹配紧跟在最后一个字符为“”“的文本节点前面的所有<hi rend="italics">个节点？
  2. 将<hi rend="italics">的内容输出为<quote>...</quote>，删除引号（“”“和”“”），但在<quote/>内包含任何出现的问号和感叹号紧跟在<hi rend="italics">的兄弟姐妹之后？
  3. 将<hi rend="italics">节点后面的“（”和“）”之间的文本节点转换为<source>...</source>，而不是括号。
  4. 包括最后的全站。

    5. 换句话说，我的输出应该如下所示：

    <root>
<p>
<element>This one is taken care of.</element> Some more text. <quote>Is this a quote?</quote> <source>Source</source>.
</p>

<p>
<element>This one is taken care of.</element> Some more text. <quote>This is a quote</hi> <source>Source</source>.
</p>

<p>
<element>This one is taken care of.</element> Some more text. <quote>This is definitely a quote!</hi> <source>Source</source>.
</p>

<p>
<element>This one is taken care of.</element> Some more text. <quote>This is a first quote</quote> <source>Source</source>. <quote>Sometimes there is a second quote as well!?</quote> <source>Source</source>. 
</p>

</root>

    我从来没有像这样处理混合内容和字符串操作，整个事情真的让我失望。我将非常感谢您的提示。

此转化：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output omit-xml-declaration="yes"/>

 <xsl:template match="node()|@*">
     <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
 </xsl:template>

 <xsl:template match=
  "hi[@rend='italics'
     and
      preceding-sibling::node()[1][self::text()[ends-with(., '„')]]
      ]">

  <quote>
    <xsl:value-of select=
     "concat(.,
             if(matches(following-sibling::text()[1], '^[?!]+'))
              then replace(following-sibling::text()[1], '^([?!]+).*$', '$1')
              else()
             )
      "/>
  </quote>
 </xsl:template>

 <xsl:template match="text()[true()]">
  <xsl:variable name="vThis" select="."/>
  <xsl:variable name="vThis2" select="translate($vThis, '„”?!', '')"/>

  <xsl:value-of select="substring-before(concat($vThis2, '('), '(')"/>
  <xsl:if test="contains($vThis2, '(')">
   <source>
    <xsl:value-of select=
      "substring-before(substring-after($vThis2, '('), ')')"/>
   </source>
   <xsl:value-of select="substring-after($vThis2, ')')"/>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

应用于提供的XML文档：

<root>
        <p>
            <element>This one is taken care of.</element> Some more text. „<hi rend="italics">Is this a
                quote</hi>?” (Source). </p>

        <p>
            <element>This one is taken care of.</element> Some more text. „<hi rend="italics">This is a
                quote</hi>” (Source). </p>

        <p>
            <element>This one is taken care of.</element> Some more text. „<hi rend="italics">This is
                definitely a quote</hi>!” (Source). </p>

        <p>
            <element>This one is taken care of.</element> Some more text.„<hi rend="italics">This is a
                first quote</hi>” (Source). „<hi rend="italics">Sometimes there is a second quote as
                well</hi>!?” (Source). </p>

</root>

生成想要的正确结果：

<root>
        <p>
            <element>This one is taken care of.</element> Some more text. <quote>Is this a
                quote?</quote> <source>Source</source>. </p>

        <p>
            <element>This one is taken care of.</element> Some more text. <quote>This is a
                quote</quote> <source>Source</source>. </p>

        <p>
            <element>This one is taken care of.</element> Some more text. <quote>This is
                definitely a quote!</quote> <source>Source</source>. </p>

        <p>
            <element>This one is taken care of.</element> Some more text.<quote>This is a
                first quote</quote> <source>Source</source>. <quote>Sometimes there is a second quote as
                well!?</quote> <source>Source</source>. </p>

</root>

这是另一种解决方案。它允许更具叙述性的输入文档（引号内的引号，一个文本节点内的多个（源）片段，'“'作为未跟随hi元素的数据）。
