我应该为正则表达式编写什么查询来捕获指示的段落格式并跳过其余部分？

Question

I am trying to write a regex query to capture either forms of following paragraphs from 'DIAGNOSIS' until before 'Board of pathologists' and ignoring the rest. What is a good regex query for this?

("" indicate the beginning and the end of paragraphs and not included in the wanted string)

("THIS IS DIAGNOSIS..." and "diagnosis result" are sample texts for the sake of the question and are replaced by different things in the data)

Paragraph format 1:

"

DIAGNOSIS:

A- THIS IS THE DIAGNOSIS, NO.1:

• diagnosis results

B- THIS IS THE DIAGNOSIS, NO.2:

• diagnosis result
• another result

Board of pathologists: . . .

"

Paragraph format 2:

"

DIAGNOSIS:

THIS IS THE DIAGNOSIS:

• diagnosis results

Board of pathologists:
. . .

"

I used "DIAGNOSIS:(\\s*)((\\w*.\\s*)*)". I know that this captures almost anything after diagnosis and my output shows that :) I couldn't find any better solution to capture the paragraphs.

Answer 1

You could match ^DIAGNOSIS: form the start of the string.

Then you could repeatedly match the following lines that do not start with Board of pathologists: using a negative lookahead (?:(?!Board of pathologists:).*\\r?\\n)*

^DIAGNOSIS:\s*(?:\r?\n)(?:(?!Board of pathologists:).*\r?\n)*
