How to extract key and value from a string - regex

Question

I want to extract some keys and their values from a string.
It seems that the program needs using regex, but I do not know it well

The string is like this
adprod_type^B6^Apr_flag^B0^Asource^B^Asource_id^B^Aadprod_params^Bheight^D^Chtml^D<style>img{width:100% !important; height:100% !important}</style>\\n<script>gAdController.passback();</script>^Cwidth^D^Aadprodset_id^B9123^Aadserve^B
What expected is like this
adprod_type:'6',pr_flag:'0',source:'',source_id:'',adprod_params:{height:'',html:'<style>img{width:100% !important; height:100% !important}</style>\\n<script>gAdController.passback();</script>',width:''},adprodset_id:'9123',adserve:''
I tried this :
file_obj = open("/Users/icko/Documents/000/a.txt")
all_lines = file_obj.readlines()
for line in all_lines:
a = line.split('^A')
for i in a:
b = i.split('^B')
key = b[0]
val = b[1]
data[key] = val
if data['adprod_type'] == '6':
print('key=' + key)
print('value=' + val)
file_obj.close()
Thank you

I tried this:
if __name__ == '__main__':
file_obj = open("/Users/icko/Documents/000/a.txt")
all_lines = file_obj.readlines()
for line in all_lines:
data = {}
a = line.split('')
for i in a:
b = i.split('')
key = b[0]
val = b[1]
data[key] = val
if data['adprod_type'] == '6':
metadata = {}
metadata1 = {}
metadata2 = {}
metadata3 = {}
subdata = data['adprod_params']
c = subdata.split('')
data1 = c[0].split('')
data2 = c[1].split('')
data3 = c[2].split('')
key1 = data1[0]
key2 = data2[0]
key3 = data3[0]
val1 = data1[1]
val2 = data2[1]
val3 = data3[1]
metadata1[key1] = val1
metadata2[key2] = val2
metadata3[key3] = val3
metadata = dict(metadata1, **metadata2, **metadata3)
print(metadata)
success!
