I spent some time looking for a way to solve this but I failed. I'll
appreciate some advice.
I want to parse lines of text. The lines include all kinds of words,
numbers, expressions etc.
I need to distinguish the lines according the first letter of the
first word. This letter determines the format of the rest of the
line. Identifying the first character will allow to use the correct
set of tokens.
The problem is that these first letters that identify the line
format, can appear any place else in the lines. My standard word
token includes these characters as well. This causes ambiguities and
Mline p1 p2 p3 p4 a=12 g=34 sdf sdf
Rline p1 p2 asd=23 sdf
Yline p1 p2
How do you suggest I approach this problem?
