Concatenate text between patterns in individual strings
In any given file, wherever a certain data block exists I need to concatenate the values(text after each "=" sign) from that block. in that block. The block starts and ends with specific pattern, say BEGIN DS and END DS respectively. The block size may vary. A file will have multiple such blocks. So say if there are 6 such blocks then I need 6 strings which have data in those respective blocks. Kindly guide.

Eg. "$file" has content :
Code:
 
Some lines of 
text
Begin DS
var1=some
var2=text 2 b concatenated 
End DS 
some more 
data
Begin DS
var1=some more
var2=text
var3=2 concatenate in 
var4=next string
End DS
:
:
so on

OUTPUT :::
Code:
 
text 2 b concatenated 
some more text 2 concatenate in next string
:

I know how to use sed for this if the block size was fixed ...
