parse string problem formating string output help!!

penny336

i'am suck at a parse string problem. so bad can't use xml..

given a paragraph.

"
%%this is line 1 level 1 ?? this is line 1 level 2 && this is line 1 level3
%%this is line 2 level 1 ?? this is line 2 level 2 && this is line 2 level3
%%this is line 3 level 1 ?? this is line 3 level 2 && this is line 3 level3
%%this is line 4 level 1 ?? this is line 4 level 2 && this is line 4 level3
"

the parse result should be

this is line 1 level 1
----this is line 1 level 2
---------- this is line 1 level3

this is line 2 level 1
----this is line 2 level 2
---------- this is line 2 level3

this is line 3 level 1
----this is line 3 level 2
---------- this is line 3 level3

,...

any one can share the php code.
really appreciate.

read the para line by line
use a combination of substr() and strpos()

use strpos() to get position of ?? then cut the string[copy of the string] up using substr() to get data between %% and ??

then for the next do the same to get data between ?? and &&

and for the last get data from && to end

thx ur help..

it is very urgent... will be better if u can show me the real coding

and also
the level 2 and level 3 are optional.. there may not have level 2 or level 3 in the paragraph after level 1 %%

%%this is line 1 level 1 ?? this is line 1 level 2 && this is line 1 level3
%%this is line 2 level 1

%%this is line 3 level 1 ?? this is line 3 level 2

%%this is line 4 level 1 ?? this is line 4 level 2 && this is line 4 level3

and the string will mix up too... will not line by line
e.g.
%%this is line 1 level 1 ?? this is line 1 level 2 && this is line 1 level3%%this is line 2 level 1%%this is line 3 level 1 ?? this is line 3 level 2%%this is line 4 level 1 ?? this is line 4 level 2 && this is line 4 level3

thx thx
