I have an input text file that I read line by line into a standard string.

Each line has the following format:

Name1  00 12 3a 4c ff …

Name2  33 55 5c dd ee …

How do create the grammer to skip the leading NameX on each line and put the hex digits into a vector?

If the lines had a more complex format such that anything could appear before NameX for example:

Bla bla bla : 0a .bb cc  NameX 01 22 aa dd 33 44 50 00 …

How could I once again get the hex digits after the name into a vector?
