正则表达式，晕了解决思路

正则表达式，晕了
A55A0024850100000CE2801105200043049C830079000000000000000000000000DB0D0AA55A0024850100000CE2003412013BF00008E3481E1A0D013300045FFBFFFFDC50160D0A

按照开头是A55A002485 结尾是0D0A分成两个数组，用正则表达式怎么写？？？
------解决方案--------------------
正则表达式:(?is)A55A002485.*?0D0A
------解决方案--------------------
