如何使用 ComponentsSeparatedByString: 忽略包含子字符串的单词？

发布于 2024-12-06 04:31:27 字数 778 浏览 0 评论 0原文

我想使用 -componentsSeparatedByString: 解析以下字符串：

     CHAPTER 5. RULE OF DECISION
 CHAPTER 6. GOVERNMENTAL EXEMPTION FROM BOND AND SECURITY REQUIREMENTS
 CHAPTER 7. LIABILITY OF COURT OFFICERS
     SUBCHAPTER A. LIABILITY OF OFFICER
     SUBCHAPTER B. LIABILITY OF ATTORNEY
     SUBCHAPTER C. SUIT ON OFFICIAL BONDS
 CHAPTER 8. STATE EXEMPTION FROM CERTAIN FEES: FEES PAID BY OPPOSING PARTY
 CHAPTER 9. FRIVOLOUS PLEADINGS AND CLAIMS
     SUBCHAPTER A. GENERAL PROVISIONS
     SUBCHAPTER B. SIGNING OF PLEADINGS
 CHAPTER 10. SANCTIONS FOR FRIVOLOUS PLEADINGS AND MOTIONS

但是当我使用 CHAPTER 作为分隔符的字符串时，SUBCHAPTER 元素也会被分解，因为它们包含 CHAPTER在他们之内。

使用 -componentsSeparatedByString: 解析 CHAPTER 元素时，如何避免在 SUBCHAPTER 元素上停止？

原文

I would like to parse the following string using -componentsSeparatedByString::

     CHAPTER 5. RULE OF DECISION
 CHAPTER 6. GOVERNMENTAL EXEMPTION FROM BOND AND SECURITY REQUIREMENTS
 CHAPTER 7. LIABILITY OF COURT OFFICERS
     SUBCHAPTER A. LIABILITY OF OFFICER
     SUBCHAPTER B. LIABILITY OF ATTORNEY
     SUBCHAPTER C. SUIT ON OFFICIAL BONDS
 CHAPTER 8. STATE EXEMPTION FROM CERTAIN FEES: FEES PAID BY OPPOSING PARTY
 CHAPTER 9. FRIVOLOUS PLEADINGS AND CLAIMS
     SUBCHAPTER A. GENERAL PROVISIONS
     SUBCHAPTER B. SIGNING OF PLEADINGS
 CHAPTER 10. SANCTIONS FOR FRIVOLOUS PLEADINGS AND MOTIONS

but when I use CHAPTER as the string to separate by, the SUBCHAPTER elements also get broken up because they contain CHAPTER within them.

How can I avoid stopping on the SUBCHAPTER elements when parsing the CHAPTER ones using -componentsSeparatedByString:?

尝试使用正则表达式 regexKit 非常适合此目的。这将帮助您形成您正在寻找的确切模式......

NSString *regex      = @"^CHAPTER [0-9]";
NSPredicate *valtest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex]; 
ret                  = [valtest evaluateWithObject:yourText];
NSLog("Matches: %@", ret);

Try using regular expressions regexKit is perfect for this. That will help you to form the exact pattern you are looking for...

NSString *regex      = @"^CHAPTER [0-9]";
NSPredicate *valtest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex]; 
ret                  = [valtest evaluateWithObject:yourText];
NSLog("Matches: %@", ret);
