混合内容和字符串操作清理

Question

我正处于将基于文字的文档转换为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>节点具有混合内容。我在上一次迭代中处理过<element>。但现在的问题是引号和源部分出现在<hi rend= "italics"/>中，部分以文本节点的形式出现。

如何使用XSLT2.0：

1. 匹配前面紧跟文本节点的所有<hi rend="italics">节点，该节点的最后一个字符是“”？
2. 将<hi rend="italics">的内容输出为<quote>...</quote>，去掉引号(“”和“”)，但在<quote/>中包含任何出现在<hi rend="italics">兄弟姐妹之后的问号和感叹号
3. 将<hi rend="italics">节点后面的"(“和")”之间的文本节点转换为不带括号的<source>...</source>。
4. 包括最后的句号。

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>

我从来没有处理过像这样的混合内容和字符串操作，整件事真的让我失望了。我会非常感激你的建议。

这是另一种解决办法。它允许更多的叙事风格的输入文档(引号中的引号，一个文本节点中的多个(Source)片段，“”作为数据，当后面没有hi元素时)。

这个转换

<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>

在提供的XML文档上应用时

<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>

生成所需的、正确的结果

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