[xsl] Re: trouble checking "cousins"of current node

["Yang" <sfyang@xxxxxxxxxxxxx>]

Hi,  Chris,

As suggested by Wendell,

>the same element name ('war', 'civic-event' and so forth) and the same
>title. Keys would be a good way to do this.

a xslt list is attached for your reference to the solution of your problem.
So the problem of interruption by different element name  will not be an
issue.

The key is  to index the child node of document node  by using name of child
node
which is your class name.
  <xsl:key name="event" match="document/*" use="name()" />

Hope you find it useful.

Cheers,
