可能重复：从iPhone上的NSString中删除HTML标记

I have a method that i use to remove HTML tags from NSString(i made a category with that):

我有一个方法，我用来从NSString中删除HTML标签（我用它做了一个类别）：

-(NSString *) stringByStrippingHTML {
    NSRange r;
    NSString *s = [[self copy] autorelease];
    while ((r = [s rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
        s = [s stringByReplacingCharactersInRange:r withString:@""];
    return s;
}

The issue is that i want to remove all HTML tags except the <br> tags, can i able to do it?

问题是，我想删除除标签以外的所有HTML标签，我能够做到吗？

2 个解决方案

#1

You can tweak as

你可以调整为

First replce <br/> with *br/* then replace all html tags and then again replace *br/* to <br/>.

首先用* br / *复制，然后替换所有html标签，然后再将* br / *替换为
。

Or, you can use conditional replacing .. if read tag is br continue else replace.

或者，您可以使用条件替换..如果读取标记是br继续其他替换。

#2

Before calling stringByReplacingCharactersInRange: make sure the tag is not <br />.

在调用stringByReplacingCharactersInRange之前：确保标签不是
。
