POGet specific Value between Javascript Function by NSRegularExpression?

Body
copied!<p><strong>I am creating a project for learning purpose:</strong></p> <p><strong>FOR INFO :</strong> I have not used <code>UIWebView</code></p> <p>In my project I got <code>HTML</code> data(<em>content</em>) from server. This data contains all information about places(<em>from google map</em>). For getting specific data from <code>HTML</code> content I need to parse <code>HTML</code>. I parse <code>HTML</code> using <a href="https://github.com/topfunky/hpple" rel="nofollow"><code>Hpple</code></a>. And I could successfully parse HTML to get specific data (<em>Such as name,address…etc</em>), but when <strong>I need to parse latitude and longitude</strong> from <code>HTML</code> content, I am confused about how to get latitude and longitude of places, because those are part of <code>Javascript</code>. I mean these latitude and longitude data are available in <code>Javascript's</code> functions.</p> <p><strong>Javascript content that I got from Server:</strong> <em>(My limitation is that, I can only put piece of javascript code bacause this code is very very long)</em></p> <pre><code>function() { window.gHomeVPage= { title:'Hostel, Bhavnagar, Gujarat, India - Google Maps',url:'/?q\\x3dHostel,+Bhavnagar,+Gujarat,+India\\x26hq\\x3dHostel,\\x26hnear\\x3dBhavnagar,+Gujarat,+India\\x26t\\x3dm\\x26ie\\x3dUTF8',urlViewport:false,ei:'jp8tUb3uNK2ciAeQroGACw', form:{ selected:'q', q:{q:'Hostel, Bhavnagar, Gujarat, India',what:'Hostel,',near:'Bhavnagar, Gujarat, India'},d:{saddr:'',daddr:'',dfaddr:'Bhavnagar, Gujarat, India'},geocode:''}, query:{type:'l'},viewport:{center:{lat:21.757528,lng:72.15303},span:{lat:0.034314,lng:0.039956},zoom:14,mapType:'m',source:0},modules:['','strr','pphover','act_s','appiw','rst'], overlays:{sxcar:false, markers: [{id:'A',cid:'7569356420090555589',latlng:{lat:21.747064,lng:72.169678},image:'http://maps.gstatic.com/intl/en_ALL/mapfiles/markers2/circleA.png',sprite:{width:20,height:34,top:0,image:'http://maps.gstatic.com/mapfiles/markers2/red_circle_markers_A_J2.png'},icon_id:'A',ext:{width:20,height:34,shadow:'http://maps.gstatic.com/intl/en_ALL/mapfiles/circle-shadow45.png',shadow_width:37,shadow_height:34,mask:false},drg:true,laddr:'Shree Sahajanand Girls Ptc Hostel, Ghogha Road, Bhavnagar, Gujarat 364001, India',geocode:'CfYWJFjKQj0mFXjVSwEdzjhNBCmN5-3pPlpfOTHF7NFVj8ELaQ',sxti:'Shree Sahajanand Girls Ptc Hostel',name:'Shree Sahajanand Girls Ptc Hostel',infoWindow:{title:'Shree Sahajanand Girls Ptc \\x3cb\\x3eHostel\\x3c/b\\x3e',addressLines:['Ghogha Road','Bhavnagar, Gujarat 364001, India'],phones:[{number:'0278 2562529'}],basics:'\\x3cdiv transclude\\x3d\\x22iw\\x22\\x3e\\x3c/div\\x3e',moreInfo:'more info',place_url:'http://maps.google.com/local_url?dq\\x3dHostel,+Bhavnagar,+Gujarat,+India\\x26q\\x3dhttps://plus.google.com/106028699675431268945/about%3Fhl%3Den\\x26s\\x3dANYYN7mCKtIBT1JPxwi6G2b9gVDdCuVyyA',zrvOk:true,loginUrl:'https://www.google.com/accounts/ServiceLogin?service\\x3dlocal\\x26hl\\x3den\\x26nui\\x3d1\\x26continue\\x3dhttp://maps.google.com/maps/place%3Fcid%3D7569356420090555589%26q%3DHostel,%2BBhavnagar,%2BGujarat,%2BIndia%26t%3Dm%26cd%3D1%26cad%3Dsrc:ppwrev%26ei%3Djp8tUb3uNK2ciAeQroGACw%26action%3Dopenratings',lbcurl:'http://www.google.com/local/add/choice?hl\\x3den\\x26gl\\x3dIN\\x26latlng\\x3d7569356420090555589\\x26q\\x3dHostel,\\x26near\\x3dBhavnagar,+Gujarat,+India',link_jsaction:''},ss:{edit:true,detailseditable:true,deleted:false,rapenabled:true,mmenabled:true},b_s:2,approx:true,elms:[4,1,6,2,12,1,9,1,5,2,11] } } </code></pre> <p>Here in above code I want to get value of <strong><code>lat:</code></strong> and <strong><code>lon:</code></strong> from <code>latlng:{lat:21.747064,lng:72.169678}</code></p> <p>For getting it from javascript, <strong>I googled</strong> and found that I need to use <a href="https://developer.apple.com/library/mac/#documentation/Foundation/Reference/NSRegularExpression_Class/Reference/Reference.html" rel="nofollow"><code>NSRegularExpression</code></a> class for get specific matches(<em>of Data</em>) form content.</p> <p>Then I tried with following code </p> <pre><code>NSError *error = NULL; NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"(?-imsx:latlng:)" options:NSRegularExpressionCaseInsensitive error:&error]; NSArray *arrayOfAllMatches = [regex matchesInString:locationStr options:0 range:NSMakeRange(0, [locationStr length])]; for (NSTextCheckingResult *match in arrayOfAllMatches) { NSString* substringForMatch = [locationStr substringWithRange:match.range]; NSLog(@"%@",substringForMatch); } </code></pre> <p>I got output in console like this:</p> <pre><code>2013-02-28 11:35:25.051 MapExample[949:13d03] latlng: 2013-02-28 11:35:25.766 MapExample[949:13d03] latlng: 2013-02-28 11:35:26.208 MapExample[949:13d03] latlng: 2013-02-28 11:35:26.799 MapExample[949:13d03] latlng: 2013-02-28 11:35:27.303 MapExample[949:13d03] latlng: 2013-02-28 11:35:27.722 MapExample[949:13d03] latlng: </code></pre> <p>How can I get content of searched node from <code>NSRegularExpression</code> ?</p>
