我正在尝试根据特定子元素属性值的组合删除节点。在下面的示例输入中，如果vis-rank rank和home-rank rank都为'0'，我想删除整个'cfb-score'节点。我尝试了很多表达式，但似乎无法提出解决方案。有时我可以让它完全删除所有<cfb-scores>。有时它什么都不做。

我想我应该指出上面的XML是我的样式表已经在做的OUTPUT，这涉及很多修剪，一些重命名和一些重组。我的完整XSLT +原始输入的样本如下。

在上一个模板中，您可以看到我最近尝试过滤未排名的游戏。它似乎什么都不做。

答案 0 :(得分：1)
<强> （编辑）的
如果'vis-rank rank'，我想删除整个'cfb-score'节点 并且'排名等级'都是'0'。
[呻吟]为什么不制定关于输入的要求？那就是：
如果两者中
cfb-score为0，则删除@rank节点visiting-team/team-rank和home-team/team-rank。
使用以下方法很容易实现：
<xsl:template match="cfb-score[visiting-team/team-rank/@rank=0 and home-team/team-rank/@rank=0]"/>
顺便说一句，你的样式表在身份转换模板旁边有这个评论：
<!--Copy all nodes into the workspace-->
这是一种误解。这里没有“工作空间”。模板建立默认规则，其他具有较高优先级的模板可以覆盖。最终，每个节点仅由最匹配的模板处理一次。
我之所以提到这一点，是因为我认为这种误解导致了最初的混淆：样式表只读 输入。
