在 XSLT/XPath 中将 xpath xml 元素的联合表示为共同父项的子项

Question

I am trying to do something like the pseudocode xpath //noah/(shem or cham or yefet) inside an xslt stylesheet and while I can do //noah/shem | //noah/cham | //noah/yefet //noah/shem | //noah/cham | //noah/yefet //noah/shem | //noah/cham | //noah/yefet I also have the case of a 2*2 crossproduct case which gets ugly fast.

The actual stylesheet is here and I am trying to add a fact alias to f and a lang alias to l for this XML input that consists of factoids about people and things ( Chuck Norris/etc. ).

Answer 1

In XPath 2 and later you can actually use //noah/(shem, cham, yefet) or //noah/(shem | cham | yefet) . With XPath 1 you are restricted to //noah/*[self::shem or self::cham or self::yefet] .
