如何获取当前节点变量的父节点元素？
下面是我的 xslt：
<xsl:template match="/">
<xsl:call-template name="generateLinks">
<xsl:with-param name="currentPageBranchVariable" select="//Item[@CurrentPageBranch='true']"></xsl:with-param>
</xsl:call-template>
</xsl:template>
并且：
<xsl:template name="generateLinks">
<xsl:param name="currentPageBranchVariable"></xsl:param>
<xsl:value-of select="$currentPageBranchVariable/@FullName"/>
// how to get the parent node of $currentPageBranchVariable?
</xsl:template>
可以看出， $currentPageBranchVariable 是包含 Item 节点的第二个模板的变量。
如何从那里获取其父元素？
我尝试了以下方法，但没有成功：
<xsl:value-of select="../$currentPageBranchVariable/@FullName"/>
<xsl:value-of select="parent::node()/$currentPageBranchVariable/@FullName"/>
<xsl:value-of select="parent($currentPageBranchVariable)/@FullName"/>
希望问题很清楚。
也许我想做的事情是不可能的？
谢谢，
The below is my xslt:
<xsl:template match="/">
<xsl:call-template name="generateLinks">
<xsl:with-param name="currentPageBranchVariable" select="//Item[@CurrentPageBranch='true']"></xsl:with-param>
</xsl:call-template>
</xsl:template>
And:
<xsl:template name="generateLinks">
<xsl:param name="currentPageBranchVariable"></xsl:param>
<xsl:value-of select="$currentPageBranchVariable/@FullName"/>
// how to get the parent node of $currentPageBranchVariable?
</xsl:template>
As can be seen, the $currentPageBranchVariable is a variable for the second template which contains an Item node.
How would that be possible to get its parent element from there?
I tried the below but didn't work:
<xsl:value-of select="../$currentPageBranchVariable/@FullName"/>
<xsl:value-of select="parent::node()/$currentPageBranchVariable/@FullName"/>
<xsl:value-of select="parent($currentPageBranchVariable)/@FullName"/>
Hope the question is clear.
Maybe what I'm trying to do is not possible?
Thanks,

Just use：
这会选择
$currentPageBranchVariable中包含的所有节点（在本例中只有一个）的父节点集（每个节点一个）。Just use:
this selects the set of parents (one each) of all nodes (in this case just one) contained in
$currentPageBranchVariable.您将轴放置在错误的位置。
您的表达式选择了上下文节点的父级，而不是
$currentPageBranchVariable。由于您从/上的匹配调用了模板，因此没有父级可供选择@FullName。您需要使用该变量后面而不是之前的父轴从
$currentPageBranchVariable中选择父级。其中任何一个都会起作用。
You were putting the axis in the wrong spot.
Your expressions were selecting the parent of the context node, not the
$currentPageBranchVariable. Since you called the template from a match on/, there is no parent to select@FullNamefrom.You need to select the parent from the
$currentPageBranchVariableby using the parent axis following that variable, not before.Either of these will work.
