code

- (void)parser:(nsxmlparser *)parser didstartelement:(nsstring *)elementname namespaceuri:(nsstring *)namespaceuri qualifiedname:(nsstring *)qualifiedname attributes:(nsdictionary *)attributedict {     currentelementvalue = [nsmutablestring string];     [uiapplication sharedapplication].networkactivityindicatorvisible = yes;     if ([elementname isequaltostring:@"item"]) {         dealslistobj = [[dealsparsingobjects alloc] init];     }  }  - (void)parser:(nsxmlparser *)parser foundcharacters:(nsstring *)string {     [currentelementvalue appendstring:string]; }  - (void)parser:(nsxmlparser *)parser didendelement:(nsstring *)elementname namespaceuri:(nsstring *)namespaceuri qualifiedname:(nsstring *)qname {     if ([elementname isequaltostring:@"short_title"]) {         dealslistobj.itemtitle = currentelementvalue;         currentelementvalue = nil;     }     else if ([elementname isequaltostring:@"final_price"]) {         dealslistobj.price = currentelementvalue;         currentelementvalue = nil;     }     //detail view     else if ([elementname isequaltostring:@"merchant"]) {         dealslistobj.itemmerchant = currentelementvalue;         currentelementvalue = nil;     }     else if ([elementname isequaltostring:@"getdeal"]) {         dealslistobj.itemgetdeal = currentelementvalue;         currentelementvalue = nil;     }     //comparison     else if ([elementname isequaltostring:@"comparison"]) {         dealslistobj.comparison = currentelementvalue;         currentelementvalue = nil;      }     else if ([elementname isequaltostring:@"item"]) {         [resultarray addobject:dealslistobj];         [dealslistobj release];         dealslistobj = nil;         currentelementvalue = nil;     } }

it appears have dealsparsingobjects class nsmutablearray called commentsarray. instantiate array, when parsing begins reading <comparison> element.

but when parser has read <comparison> element, assign value property called comparison; doesn't added array. being default nsstring property (assumption on part), gets reassigned each time parser done reading <comparison> element.

edit:

parser:didstartelement:... called every time new element read. holds <a> tags. in method reset currentelementvalue. each <a> value reset empty string. last read value remains, value of last <a> tag plus trailing text.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
