xml - XSLT - 将一个节点中的值替换为其前一个兄弟节点的值

Question

我正在尝试编写一个 XSLT 转换，它将一个节点中的值替换为其前一个兄弟节点的值。然后返回转换后的整个文档:)

找出出现的地方

<package:packageDownloadLocator>http://myunwantedurl</package:packageDownloadLocator>

并替换为它正在进行的兄弟的文本值

<package:packagePreviewLocator>http://myurl.com</package:packagePreviewLocator>

感谢任何帮助或建议

注意:要查找的节点并不总是存在于每条记录中。

Answer 1

这个转换:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:package="info:srw/extension/13/package-v1.0" >
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

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

 <xsl:template match="package:packageDownloadLocator/text()">
  <xsl:value-of select="../preceding-sibling::*[1]/text()"/>
 </xsl:template>
</xsl:stylesheet>

应用于提供的 XML 文档时，会产生所需的结果。

请注意:

1. 使用身份规则按原样复制每个节点。

2. 使用仅匹配所需文本节点的特定模板覆盖身份规则。
