i've changed the code, make it look into /AP
it seems the values are there, but...how to get them?
You have them:
/D : Dictionary
/Off : 204 0 R
/this#20is#20value#203 : 203 0 R
/N : Dictionary
/Off : 202 0 R
/this#20is#20value#203 : 201 0 R
What's your problem?
See the attached example. What are you missing?
