目标c是否具有条带标签功能？

Question

我正在寻找一个客观的C函数(自定义或内置),从字符串中剥离html标签,类似于PHP的版本,可以在这里找到:

任何帮助,将不胜感激!

这只是删除<和>字符以及它们之间的所有内容,我认为这是足够的:

- (NSString *) stripTags:(NSString *)str
{
    NSMutableString *ms = [NSMutableString stringWithCapacity:[str length]];

    NSScanner *scanner = [NSScanner scannerWithString:str];
    [scanner setCharactersToBeSkipped:nil];
    NSString *s = nil;
    while (![scanner isAtEnd])
    {
        [scanner scanUpToString:@"<" intoString:&s];
        if (s != nil)
            [ms appendString:s];
        [scanner scanUpToString:@">" intoString:NULL];
        if (![scanner isAtEnd])
            [scanner setScanLocation:[scanner scanLocation]+1];
        s = nil;
    }

    return ms;
}
