One of the earliest special techniques to appear in XSLT 1.0 was a means to process a set of elements, each of which had an attribute (or descendant) that indicated the group to which it belonged.

XSLT 1.0 中出现最早的专门技术是处理一组元素的方式，其中每个元素都有一个属性（或后代）表明它所属的组。

The selector in the following rule, which combines descendant and attribute selectors, matches any element that (1) has the "href" attribute set and (2) is inside a P that is itself inside a DIV

下面规则中的选择符结合了派生选择符和属性选择符，它匹配任何元素，如果(1)该元素设置了"href"属性；且(2)包含在一个P元素内，而P元素又包含在一个DIV元素内
