extract text between 2 different characters

Hi I cant seem to get this formula right, being trying hard enough....

in column A starting A2 i have a lot of rows of data such as this in the attachment

I wish to extract 4 columns data starting in B2 which I have solvedthe first column in B2
But I am stuck with rest of extraction which involves the Mid function
as I said I got B2 solved

I managed to extract the first extraction which has column header Horse
But I cant solve the rest of the formulas for racno, Track and tabno
Any help will be greatly welcome
