I want to give some params to the processor to change some (not all)
"test" values. The values for the change depend on the value of the
"name" attribute.
For example: if value of name = "a" then test2 value="$XX" and test3
value="$YY"
and if name="b" then test2 value="$VV" and test3 value="$WW"
...
I tried to customize the "Identity change template"
(http://www.dpawson.co.uk/xsl/sect2/identity.html#d5687e43 ) for my needs
Yes, this is what you need to work with.
Below I've given you two approaches, one for where the name="a" and
one for where the name="b". For reasons of good style you should
consistently use the same approach, but I've given you both so you
can decide which is more appropriate for your final solution.
The first approach catches the <A> and then reconstitutes the <A> and
the required attributes.
The second approach catches only the attributes that need changing
and reconstitute only the attributes.
I hope this helps.
