[英]NSString without HTML markup
我有一個JSON數據,並且我希望將此JSON數據轉換為NSString而無需HTML標記。
這是我的JSON數據:
<p><strong style="font-size: 13px;">13th March</strong></p>
<p><span id="fbPhotoSnowliftCaption" class="fbPhotosPhotoCaption" tabindex="0" data-ft="{"tn":"K"}"><span class="hasCaption">Peak is solid 6ft + a bit wild but not a breath of wind around. Rossnowlagh will be the pick of the beaches. Very good surf forecast all weekend and into the middle of next week</span></span>.</p>
<p><span id="more-113"></span></p>
<p>High tide: 10:56, 3.2m <span style="color: #ff0000;"> <a href="http://www.bundoransurfco.com/webcam/"><strong></strong></a></span></p>
<p>Low Tide: 16:32, 1.4m</p>
<p><b>3 day forecast to March 16th</b></p>
<p>Windy midweek but the surf is looking very good from Friday onward, right through the weekend.</p>
<style type='text/css'>
我想得到這種NSString:
13th March
Peak is solid 6ft + a bit wild but not a breath of wind around. Rossnowlagh will be the pick of the beaches. Very good surf forecast all weekend and into the middle of next week.
High tide: 10:56, 3.2m
Low Tide: 16:32, 1.4m
3 day forecast to March 16th
Windy midweek but the surf is looking very good from Friday onward, right through the weekend.
我已經使用stripHtml進行了測試,但是使用它之后,我的NSString剛剛: 13th March
這是我的代碼(報告的文本始終在#gallery-1
之前,因此這不是問題所在……但是我認為帶有一些html標記...(因為使用不同的標記可以!):
NSString* stringBDD = [[dicoBDD objectForKey:@"post"] objectForKey:@"content"];
NSString *stringWithoutLiveWebcam = [stringBDD stringByReplacingOccurrencesOfString:@"CLICK HERE FOR LIVE PEAK WEBCAM" withString:@""];
NSString *stringReportFirstPart = [[stringWithoutLiveWebcam componentsSeparatedByString:@"#gallery-1"] firstObject];
NSString* stringWithoutHtml = [stringReportFirstPart stripHtml];
NSLog(@"stringWithoutHtml : %@", stringWithoutHtml);
您可以使用正則表達式</?[^>]*>
匹配HTML標簽。 使用帶有正則表達式的stringByReplactingMatchesInString
和空字符串替換,可以刪除標簽。
@interface NSString (HTML)
- (NSString *)stripTags;
@end
@implementation NSString (HTML)
- (NSString *)stripTags {
NSError *error = nil;
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"</?[^>]*>"
options:0
error:&error];
if (error == nil) {
return [regex stringByReplacingMatchesInString:self
options:0
range:NSMakeRange(0, self.length)
withTemplate:@""];
} else {
return self;
}
}
@end
