Task create one clase with the 2 methods below. ARC, iOS 7 only
#Class
PQHTMLParser
##Method 1
- (NSString*)plainTextFromHTML:(NSString*) html;
parameter: a string containing html
return: a string stripped of all HTML tags with the guidance below
Guidance:
Use this code as a starting place. It does 90% of the job:
https://github.com/mwaterfall/MWFeedParser/blob/master/Classes/NSString%2BHTML.h#L37
Then improve it to do these 3 things:
1. Convert all line breaks (<br/>, <br />, and <br>) into @"\n"
2. Add 2 new lines (@"\n\n") after <p></p> tags
3. Convert a href tags to plain text like this:
"<a href="http://link.com" >Link Text</a>" ->
"Link Text (http://link.com)"
Test by converting the following HTML:
@"<p><img src="http://feeds.twit.tv/podcasts/coverart/mbw144audio.jpg" align="right" hspace="20" vspace="20" border="0" title="MacBreak Weekly" alt="MacBreak Weekly"/></p><p><b>Hosts:</b> <a href="http://leoville.com">Leo Laporte</a>, <a href="http://www.imore.com/">Rene Ritchie</a>, <a href="http://www.cwob.com">Andy Ihnatko</a>.</p>

##Method 2
- (NSArray*)linksFromHTML:(NSString*) html;
parameter: a string containing html
return: an array of dictionaries. Each dictionary contains one key value pair: @{@"Link Text" : @"http://link.com"}
Guidance:
My suggestion is to use this:
https://github.com/zootreeves/Objective-C-HMTL-Parser
But if you have a parser you are familiar with and would rather use that is ok ,too.
