let's consider following format of raws:

| Node[42]{id:42} | Node[208813]{id:208813} | Node[292823]{id:292823} |

Is is possible to use Linux tools to map it into:
42,208813,292823

Where, these numbers are numbers gathered from [].
Please note that I search for universal method for more columns, for example:
| Node[42]{id:42} | Node[208813]{id:208813} | Node[292823]{id:292823} | Node[1]| into

42,208813,292823,1.
Please note also that {id:292823} is optional (it is not mandatory).

Can anyone help?

With sed:

sed 's/[^[]*\[//;s/\][^[]*\[/,/g;s/].*//' file

Output:

42,208813,292823

See: man sed and The Stack Overflow Regular Expressions FAQ
