XSLT - 用一个节点之前的值替换一个节点中的值

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它的前一个兄弟的值.然后返回整个文件转换:)

找出事件的发生

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

并替换为正在进行的兄弟的文本值

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

感谢您的任何帮助或建议

注意:要查找的节点并不总是存在于每条记录中.

由此:

Answer 1

这种转变:

<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>

当应用于提供的XML文档时,生成想要的结果.

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标识规则.
