XSLT 3.0 如何在一个元素中连接特定元素文本

Question

您好，我有这个示例，其中包含多个产品，每个产品都带有元素 text，然后每个都有附加元素 >text.. .>. 我想将它们全部合并到包含到以逗号 (,) 分隔的的元素。

    <shop>
  <products>
    <product>
      <price>176.5500</price>
      <pricecustomer>154.4812</pricecustomer>
      <product_id>6167</product_id>
      <model>BUN-001</model>
      <ean></ean>
      <mpn>BUN-001</mpn>
      <isbn>0</isbn>
      <minimum>1</minimum>
      <tax_class>1</tax_class>
      <quantity>0</quantity>
      <main_image>https://www.test.com/image/products/Bundles/bundle-001.jpg</main_image>
      <manufacturer></manufacturer>
      <varos>0.00000000</varos>
      <mikos>0.00000000</mikos>
      <platos>0.00000000</platos>
      <ipsos>0.00000000</ipsos>
      <status>Published</status>
      <image_1>https://www.test.com/image/products/beper/bt.200/BT.200.jpg</image_1>
      <image_2>https://www.test.com/image/products/beper/bt.200/BT.200-1.jpg</image_2>
      <image_3>https://www.test.com/image/products/zilan/zln7887/ZLN7887.jpg</image_3>             
    </product>
  </products>
</shop>

我想要的结果是这个

<shop>
  <products>
    <product>
      <price>176.5500</price>
      <pricecustomer>154.4812</pricecustomer>
      <product_id>6167</product_id>
      <model>BUN-001</model>
      <ean></ean>
      <mpn>BUN-001</mpn>
      <isbn>0</isbn>
      <minimum>1</minimum>
      <tax_class>1</tax_class>
      <quantity>0</quantity>
      <main_image>https://www.test.com/image/products/Bundles/bundle-001.jpg,https://www.test.com/image/products/beper/bt.200/BT.200.jpg,https://www.test.com/image/products/beper/bt.200/BT.200-1.jpg,https://www.test.com/image/products/zilan/zln7887/ZLN7887.jpg</main_image>
      <manufacturer></manufacturer>
      <varos>0.00000000</varos>
      <mikos>0.00000000</mikos>
      <platos>0.00000000</platos>
      <ipsos>0.00000000</ipsos>
      <status>Published</status>
      <image_1>https://www.test.com/image/products/beper/bt.200/BT.200.jpg</image_1>
      <image_2>https://www.test.com/image/products/beper/bt.200/BT.200-1.jpg</image_2>
      <image_3>https://www.test.com/image/products/zilan/zln7887/ZLN7887.jpg</image_3>
          
    </product>
  </products>
</shop>

我已经用 XSLT 尝试过这段代码

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:xs="http://www.w3.org/2001/XMLSchema"
   exclude-result-prefixes="xs"
   version="2.0">
   
   <xsl:mode on-no-match="shallow-copy"/>
   
   <xsl:template match="main_image">
      
         <xsl:value-of select="if (../../../main_image/text()) then string-join((image_*/text()), ',') else ''"/>            
         <xsl:value-of select="."/>
      
   </xsl:template>
   
</xsl:stylesheet>

结果根本没有主图像，我错过了什么？感谢您的帮助

Answer 1

您可以使用

   <xsl:template match="main_image">
      <xsl:copy>
         <xsl:value-of select="., ../*[matches(local-name(), '^image_')]" separator=","/>            
      </xsl:copy>      
   </xsl:template>
