How can I find text with linktext in a field

[Reinhold Venzl-Schubert]

Hi!

In the field "answer" of a learning program I use some words as  
linkText to switch to another stack with cards that show some examples.

on linkclicked theLink
     go cd theLink of stack "examples"
...

Now I want to export and delete those cards of my learning program.  
Therefore I will find the linkTexts of the field "answer" in a card  
and list them in the field or variable "linkList" or similar. Some  
linkText are a single word, others consist of two words with a space.

I tried sometimes myself but I don't have many experience and I failed.
Do anybody knows a possibility to find the linkTexts?

Thanks
Reinhold
