xsl:variable 作为其他 xsl 标记的 xpath 值 [英] xsl:variable as xpath value for other xsl tag

问题描述

我在使用 xsl:variable 时遇到问题.我想创建一个变量，其值取决于另一个 XML 节点属性的值.这工作很好.但是，当我尝试使用代表 XPath 的字符串值创建变量时，当我尝试在稍后的 XSL 标记中将其用作 XPath 时，它就不起作用了.

I'm having issues with xsl:variable. I want to create a variable with a value that depends on the value of another XML node attribute. This working good. But when I try to create a variable with a string value that represents XPath, it just doesn't work when I try to use it as XPath in a later XSL tag.

<xsl:variable name="test">  
  <xsl:choose>
    <xsl:when test="node/@attribute=0">string/represent/xpath/1</xsl:when>
    <xsl:otherwise>string/represent/xpath/2</xsl:otherwise>
  </xsl:choose>       
</xsl:variable>                 
<xsl:for-each select="$test">
  [...]
</xsl:for-each>

我试过:如何在 xsl if 中使用 xsl 变量和xsl:for-each selection using xsl:variable 的问题.但没有结果.

I tried: How to use xsl variable in xsl if and trouble with xsl:for-each selection using xsl:variable. But with no results.

推荐答案

如果像这种情况那样事先知道那些路径，那么你可以使用:

If those path are known in advance like this case, then you can use:

<xsl:variable name="vCondition" select="node/@attribute = 0"/>
<xsl:variable name="test" select="actual/path[$vCondition] |
                                  other/actual/path[not($vCondition)]"/>
