Question

我可以在全局范围内声明一个值为“111”的变量“myVariable”。但是如何在本地重新分配值。或者是否有另一种方法来实现这一目标。

请帮忙。谢谢。拉维

Answer 1

您可以在模板中重新定义相同的变量：

<xsl:variable name="myVariable" select="'111'"/>

<xsl:template match="/">
  <xsl:variable name="myVariable" select="'112'"/>
  . . . 
</xsl:template>

请注意，虽然XSLT中的“变量”实际上是常量 - 您没有为同一个变量重新分配不同的值，而是在模板中重新定义它 - 在模板myVariable之外仍然会有值111。

您可以使用jscript / vbscript完成您想要的操作。这是使用Jscript的示例。
