Excuse me under such as char * XX="xiao Ming clothes 1 2 | | xiao Ming clothes xiao Ming to the | |" welcome

How to get to the segmentation

My demand is to get the length after removing | like see now have 4

Then separately for content 1 2 3 content 4 content

Using two-dimensional array
Read to save it to a string array | stops,
Then read to save to the next member of the two-dimensional array
Cycle can be
