HTML解析为空格,当我从源代码解析HTML文本时，段落之间存在任意空格

我将源代码从网站存储到字符串，并成功删除了所有html标记。但是，段落之间有随机的空格。有时它只会是一条线，其他时候会是四条或五条线。当我从源代码解析HTML文本时，段落之间存在任意空格

这里是我做过什么

- (NSString *)parseHTMLText:(NSString *)text {

NSString *startingPt = @"";

NSString *endingPt = @"";

//isolate body text from entire source code

NSString *leftTrimmed = [text substringFromIndex:NSMaxRange([text rangeOfString:startingPt])] ;

NSString *completeTrimmed = [leftTrimmed substringToIndex:[leftTrimmed rangeOfString:endingPt].location];

completeTrimmed = [completeTrimmed stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

completeTrimmed = [self removeHTMlTagsFromString:completeTrimmed];

completeTrimmed = [completeTrimmed stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

return completeTrimmed;

}

- (NSString *)removeHTMlTagsFromString:(NSString *)text {

//check if there are any html tags

if ([text rangeOfString:@""].location != NSNotFound) {

//find first index of "

int startIndex = [text rangeOfString:@"

NSString *startOfTag = [text substringFromIndex:startIndex];

// find length to ">"

int length = [startOfTag rangeOfString:@">"].location + 1;

text = [text stringByReplacingCharactersInRange:NSMakeRange(startIndex, length) withString:@""];

text = [self removeHTMlTagsFromString:text];

}

return text;

}

我尝试这样做，但它不工作

completeTrimmed = [completeTrimmed stringByReplacingOccurrencesOfString:@" " withString:@""];
