XSLT 剥离所有级别的标签答案

【问题标题】：XSLT Stripping Tags at All LevelsXSLT 剥离所有级别的标签
【发布时间】：2019-05-06 16:02:13
【问题描述】：

我有一些 XML 需要使用 XML 进行转换。当我创建我的 XSLT 时，数据是一种格式，但后来我改变了格式，所以我需要相应地更改我的 XSLT。

XSLT 应该创建一个原始文本标签，然后去掉句子<S> 标签中的元数据并将它们附加到变量名（即<ENAMEX type="PERSON"... 变为ENAMEX_PERSON）。之前整个 xml 是 <DOC> ... </DOC>，但现在是 <NORMDOC> <DOC> ... </DOC> ... </NORMDOC>，所以我在我的选择模式中修复了它，但现在它删除了 <TXT> 之前的所有标签，而在我的选择模式只是 DOC/ 之前它没有。如何更改我的 XSLT 使其仅在 TXT 中执行此剥离？

【解决方案1】：

AFAICT，以下样式表返回预期结果：

XSLT 1.0

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:template match="/NORMDOC">
    <xsl:apply-templates select="DOC"/>
</xsl:template>

<xsl:template match="*">
    <xsl:copy>
        <xsl:apply-templates/>
    </xsl:copy>
</xsl:template>

<xsl:template match="TXT">
    <RAW_TXT>
        <xsl:value-of select="."/>
    </RAW_TXT>
    <xsl:copy>
        <xsl:apply-templates/>
    </xsl:copy>
</xsl:template>

<xsl:template match="S">
    <xsl:copy>
        <xsl:apply-templates select="*" mode="extra"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="*" mode="extra">
    <xsl:element name="{name()}_{@type}">
        <xsl:apply-templates/>
    </xsl:element>
</xsl:template>

</xsl:stylesheet>

【讨论】：

这几乎是完美的，谢谢！但是，最后我得到了<ENTINFO/>，而<WH_> 则分散在各处。关于如何摆脱这些的任何建议？
@carousallie 我已经编辑了我的答案，所以排除了<ENTINFO/>。我看到的唯一<WH_> 节点也是出现在您的预期输出中的两个节点。

【解决方案2】：

覆盖身份规则是解决问题的最佳方法。这个样式表：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:template match="node()|@*" name="identity">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

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

  <xsl:template match="TXT">
    <RAW_TXT>
      <xsl:value-of select="."/>
    </RAW_TXT>
    <xsl:call-template name="identity"/>
  </xsl:template>

  <xsl:template match="TXT/S/text()|ENTINFO"/>
</xsl:stylesheet>

输出：

注意：对NORMDOC 元素使用“绕过规则”；使用 empty rule 剥离 S' 文本节点子节点和 ENTINFO 元素 和后代；使用命名模板能够覆盖 TXT 元素的标识规则，但不会失去重用它的机会。
