Re: [xsl] single display of double elements but how to use generate-id

[Heiko Specht <heiko@xxxxxxxxxx>]

Hello all,

if have found a solution of my problem
in my own script.

the solution was to create a new variable (see the commend) and
than to generate-id of the variable node-set
how easy it could be.

but another question: where to find a good tutorial about
node, nodeset and this parent:: self:: ancestor:: and so on
i need to understand this stuff.
a long time ago there was a good xsl tutorial downloadable at
mullberry.

TIA

Heiko
