我想更改图像路径。

显示图像的代码是:
<xsl:value-of select="image"/>

它从提要中获取的图像路径是:

https://www.website.com/media/catalog/product/1/7/image.jpg

我想要的是:

https://www.website.com/media/catalog/product/thumbnail/folder/1/7/image.jpg

我尝试了以下操作:

<xsl:template name="string-replace-all">
    <xsl:param name="text"/>
    <xsl:param name="replace"/>
    <xsl:param name="with"/>

    <xsl:choose>

      <xsl:when test="contains($text,$replace)">

        <xsl:value-of select="substring-before($text,$replace)"/>
        <xsl:value-of select="$with"/>

        <xsl:call-template name="string-replace-all">
          <xsl:with-param name="text" select="substring-after($text,$replace)"/>
          <xsl:with-param name="replace" select="$replace"/>
          <xsl:with-param name="with" select="$with"/>
        </xsl:call-template>

      </xsl:when>

      <xsl:otherwise>
        <xsl:value-of select="image"/>
      </xsl:otherwise>

    </xsl:choose>
</xsl:template>


<xsl:template match="root">
    <xsl:for-each select="product[position() = 1]">


    <xsl:call-template name="string-replace-all">
    <xsl:with-param name="text" select="'https://www.website.com/media/catalog/product/'"/>
    <xsl:with-param name="replace" select="'product/'" />
    <xsl:with-param name="with" select="'product/thumbnail/folder/'"/>

    </xsl:call-template>

   </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

输出为:

https://www.website.com/media/catalog/product/thumbnail/folder/https://www.website.com/media/catalog/product/image.jpg

没有得到真正的错误消息,它只是显示了两倍的http部分

这难道不是很简单吗?例如,考虑:

XML

<root>
    <product>
        <image>https://www.website.com/media/catalog/product/1/7/image.jpg</image>
    </product>
    <product>
        <image>https://www.website.com/media/catalog/product/2/56/image.jpg</image>
    </product>
    <product>
        <image>https://www.website.com/media/catalog/product/3/123/image.jpg</image>
    </product>
</root>

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"/>

<xsl:template match="/root">
    <images>
        <xsl:for-each select="product">
            <image>
                <xsl:text>https://www.website.com/media/catalog/product/thumbnail/folder/</xsl:text>
                <xsl:value-of select="substring-after(image, 'https://www.website.com/media/catalog/product/')" />
            </image>
        </xsl:for-each>
    </images>
</xsl:template>

</xsl:stylesheet>

结果

<?xml version="1.0" encoding="UTF-8"?>
<images>
  <image>https://www.website.com/media/catalog/product/thumbnail/folder/1/7/image.jpg</image>
  <image>https://www.website.com/media/catalog/product/thumbnail/folder/2/56/image.jpg</image>
  <image>https://www.website.com/media/catalog/product/thumbnail/folder/3/123/image.jpg</image>
</images>
