Swift parse html table -


i trying bring info web page ios app.

html code:

<table border="0" cellpadding="3" cellspacing="0" width="85%"><tr><td width="100%" colspan="3" bgcolor="#c9c9e7"><b>update of 3:57:00 pm (cdt) thu., apr. 16, 2015</b><br></td></tr><tr> <td width="50%" bgcolor="#ffffff">production line 1</td> <td width="35%" bgcolor="#ffffff">9:00 minutes  (10 min)&nbsp;</td> <td width="15%" bgcolor="#ffffff">no delay</td> </tr><tr> <td width="50%" bgcolor="#ffffff"><b>production line 2</b></td> <td width="35%" bgcolor="#ffffff"><b>7:57 minutes  </b><b>(4 min)&nbsp;</b></td> <td width="15%" bgcolor="#ffffff"><b>+3:57</b></td> </tr><tr> <td width="50%" bgcolor="#ffffff"><b>production line 3</b></td> <td width="35%" bgcolor="#ffffff"><b>10:35 minutes  </b><b>(8 min)&nbsp;</b></td> <td width="15%" bgcolor="#ffffff"><b>+2:35</b></td> </tr></table>

this current attempt @ code. have marked line think issue // issue. optional nil values. using swift-html-parser make happen. made 1 change , add section table. 

import uikit extension string { var html2string:string {     return nsattributedstring(data: datausingencoding(nsutf8stringencoding)!, options: [nsdocumenttypedocumentattribute:nshtmltextdocumenttype,nscharacterencodingdocumentattribute:nsutf8stringencoding], documentattributes: nil, error: nil)!.string    } }  class mainviewcontroller: uiviewcontroller {  @iboutlet var textview: uitextview!   override func viewdidload() {     super.viewdidload()     updatetrafficinfo()      let singlefingertap = uitapgesturerecognizer(target: self, action: "handlesingletap:")     self.textview.addgesturerecognizer(singlefingertap) }  // mark: gestutre recognizer func handlesingletap(recognizer: uitapgesturerecognizer) {     updatetrafficinfo() }  func updatetrafficinfo(){     var request = httptask()     var err: nserror?     request.get("http://localhost/productiontimes.html", parameters: nil, success: {(response: httpresponse) in         if let data = response.responseobject as? nsdata {             let rawhtml = nsstring(data: data, encoding: nsutf8stringencoding) as! string             let option = cint(html_parse_noerror.value | html_parse_recover.value)              var parser = htmlparser(html: rawhtml, encoding: nsutf8stringencoding, option: option, error: &err)             if err != nil {                 println(err)             }             var bodynode = parser.table             if let inputnodes = bodynode?.xpath("//tr") {                 node in inputnodes {                     dispatch_sync(dispatch_get_main_queue(), {                     self.textview.text = node.xpath("//td")?[0].contents  //issue                     println(node.xpath("//td")?[0].contents)                     });                 }             }               dispatch_sync(dispatch_get_main_queue(), {                 self.textview.text = rawhtml.html2string               });          }         },failure: {(error: nserror, response: httpresponse?) in             println("error: \(error)")     }) }    override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }   }

goal have output in format of this.

production line  -      time  -                     delay production line 1 -     9:00 minutes  (10 min) -    no delay production line 2 -     7:57 minutes  (4 min) -     +3:57 

extension nsdata {     var htmldata2string:string {         return nsattributedstring(data: self, options: [nsdocumenttypedocumentattribute : nshtmltextdocumenttype, nscharacterencodingdocumentattribute : nsutf8stringencoding], documentattributes: nil, error: nil)!.string     } }  let output = data.htmldata2string let components = output.componentsseparatedbystring("\n") index in stride(from: 1, to: 9, by: 3) {     let line = components[index]     let time = components[index+1]     let delay = components[index+2]     println( line + " - " + time + " - " + delay ) }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
