如何使用 XSL 将 xml 属性转换为 solr 添加文档中的元素

Question

我很难修复 xml 转换的最后一部分。欢迎任何帮助。还创建了一个fiddle：https://xsltfiddle.liberty-development.net/93FcQpw

我的xml:

目前我创建的xsl：

<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>

<xsl:output method="xml" encoding="utf-8" indent="yes" />
    <xsl:strip-space elements="*"/>

    <xsl:template match="images/*">

       <xsl:element name="field">
            <xsl:attribute name="name"><xsl:value-of select="local-name()"/></xsl:attribute>
            <xsl:value-of select="."/>
        </xsl:element>
    </xsl:template>    

    <xsl:template match="categories/*">

       <xsl:element name="field">
            <xsl:attribute name="name"><xsl:value-of select="local-name()"/></xsl:attribute>

    <xsl:template match="property">
        <xsl:element name="field">

  <xsl:template match='/products'>
    <add>
      <xsl:apply-templates select="product"/>
    </add>
  </xsl:template>

  <xsl:template match="product">

    <doc>

      </xsl:apply-templates>
    </doc>

当前输出缺少 ID 属性，我还想要一个 ;单独的图片网址列表：

<?xml version="1.0" encoding="utf-8"?>

      <field name="category">Category1</field>
      <field name="categoryPath_s">Huis en tuin &gt; Planten &gt; Bloemen</field>
      <field name="EAN_s"/>
      <field name="fromPrice_s">18.95</field>

      <field name="image">image2</field>
      <field name="description">desc</field>
      <field name="category">Category2</field>
      <field name="categoryPath_s">A &gt; B &gt; C</field>
      <field name="EAN_s"/>
      <field name="fromPrice_s">12.85</field>
      <field name="imageURL_large_s">https://www.xxx.nl/wp-content/uploads/2021/05/xxxx-Boven.png</field>

      <field name="subcategories_s">sub2</field>

想要的输出，寻找 ID 属性作为元素和 ; imageURL_small_s 元素的分隔列表：

      <field name="image">image1</field>
      <field name="description">desc</field>
      <field name="category">Category1</field>
      <field name="categoryPath_s">Huis en tuin &gt; Planten &gt; Bloemen</field>
      <field name="EAN_s"/>
      <field name="fromPrice_s">18.95</field>
      <field name="imageURL_large_s">https://www.xxx.nl/wp-content/uploads/2021/05/xxxx-Boven.png</field>

Answer 1

我相信这可以简单得多：

XSLT 3.0

<xsl:stylesheet version="3.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
expand-text="yes">
<xsl:output method="xml" encoding="utf-8" indent="yes" />
<xsl:strip-space elements="*"/>

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

<xsl:template match="product">
    <doc>
        <field name="ID">{@ID}</field>
        <xsl:apply-templates/>
    </doc>
</xsl:template>

<xsl:template match="*[text()]">
    <field name="{name()}">{.}</field>
</xsl:template>    

<xsl:template match="property">
    <field name="{@name}">
        <xsl:value-of select="value" separator=" ; "/>
    </field>
</xsl:template>   

</xsl:stylesheet>
