我有这个：
<a>
<b>
<t>text</t>
</b>
</a>
<a>
<t>text</t>
</a>
所以我想选择文本,不管它在哪里.
(注意,它可以在任何地方不只是1/2级别,它可以没有父母)
这可能吗？
您正在寻找
the
descendant axis：
the @H_404_14@descendant axis contains the descendants of the context node; a
descendant is a child or a child of a
child and so on; thus the descendant
axis never contains attribute or
namespace nodes
在你的情况下：/后代：t
当然,正如其他人回答的那样,there is an abbreviated syntax for this：
@H_404_14@// is short for @H_404_14@/descendant-or-self::node()/. For
example,@H_404_14@//para is short for
@H_404_14@/descendant-or-self::node()/child::para
and so will select any @H_404_14@para element
in the document (even a @H_404_14@para element
that is a document element will be
selected by @H_404_14@//para since the document element node is a child of the root node)
