如何通过正则表达式拆分多行文本(How to split multiple line text by regex)

如何通过正则表达式拆分多行文本(How to split multiple line text by regex)

我有多行文字

SUBJECT=Testing001 TEXT=TestingLine001-Test TEXT=TestingLine002-Test REFER=Reference001 SUBJECT=Testing002 TEXT=TestingLine003-Test SUBJECT=Testing003 TEXT=TestingLine004-Test REFER=Reference002

只想分割文本块（对于这种情况，三个文本块，“主题”是文本块的第一行），如：

SUBJECT=Testing001 TEXT=TestingLine001-Test TEXT=TestingLine002-Test REFER=Reference001 SUBJECT=Testing002 TEXT=TestingLine003-Test SUBJECT=Testing003 TEXT=TestingLine004-Test REFER=Reference002

I have multiple lines text

SUBJECT=Testing001 TEXT=TestingLine001-Test TEXT=TestingLine002-Test REFER=Reference001 SUBJECT=Testing002 TEXT=TestingLine003-Test SUBJECT=Testing003 TEXT=TestingLine004-Test REFER=Reference002

Just want to split text blocks (for this case, three text blocks, "Subject" is the first line of the text block) like as:

SUBJECT=Testing001 TEXT=TestingLine001-Test TEXT=TestingLine002-Test REFER=Reference001 SUBJECT=Testing002 TEXT=TestingLine003-Test SUBJECT=Testing003 TEXT=TestingLine004-Test REFER=Reference002
