xml - XSLT 如何组合模板并将现有字段添加到某些元素

问题描述

我正在尝试更改 xml 文件，已尝试多次但无法获得任何有意义的输出。转换后的 xml 文件应为：

  1. 无遮罩属性
  2. 版本和状态字段应该从所有节点中删除
  3. 字段编号必须是记录、元素1、元素2、元素等的顶部字段。

任何帮助将不胜感激

这是我的 xml 输入：

当前 xslt ：

  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:output omit-xml-declaration="yes" indent="yes"/>
  <xsl:strip-space elements="*"/>
  
  <xsl:template match="node() | @*">
    <xsl:copy>
      <xsl:apply-templates select="node() | @* "/>
    </xsl:copy>
  </xsl:template>
  
  <xsl:template match="@mask"/>
  
  <xsl:template match="version | status"/>
  
  <xsl:template match="Record | Record/links/link/element1 | Record/links/link/element2 | Record/links/link/element3 | Record/links/link/element4">
        <xsl:copy>
          <xsl:apply-templates select="@*"/>
          <xsl:apply-templates select="Number"/>
      <xsl:apply-templates/> 
        </xsl:copy>
      </xsl:template>

  
  </xsl:stylesheet>

期望的结果：

    <Objects>
        <Record>
            <Number>999999</Number>
            <reference>104006ALS</reference>

解决方案

你快到了 - 试试：

XSLT 1.0

<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" omit-xml-declaration="yes"/>
<xsl:strip-space elements="*"/>

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

<xsl:template match="@mask | version | status"/>

<xsl:template match="Record | element1 | element2 | element3 | element4">
    <xsl:copy>
        <xsl:apply-templates select="@*"/>
        <xsl:copy-of select="ancestor-or-self::Record/Number"/>
        <xsl:apply-templates/> 
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>

如果（从您的示例中可以看出）除了 之外没有其他属性mask，您可以将代码简化为：

<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" omit-xml-declaration="yes"/>
<xsl:strip-space elements="*"/>

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

<xsl:template match="version | status"/>

<xsl:template match="Record | element1 | element2 | element3 | element4">
    <xsl:copy>
        <xsl:copy-of select="ancestor-or-self::Record/Number"/>
        <xsl:apply-templates/> 
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>
