これがあなたが使うことができる方法ですNSXMLParser
:
.hファイルで次のように宣言します。
NSMutableData *webPortFolio;
NSMutableString *soapResultsPortFolio;
NSURLConnection *conn;
//---xml parsing---
NSXMLParser *xmlParserPortFolio;
BOOL elementFoundPortFolio;
NSMutableURLRequest *req;
NSString *theXMLPortFolio;
NSString *strSoapMsg;
UIAlertView *alertView;
.mファイルで次のコードを使用します。
-(void)callURL
{
//Your logic to call URL.
conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
if (conn)
{
webPortFolio = [[NSMutableData data] retain];
}
}
また、応答を処理するには、次の関数を使用できます。
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[webPortFolio setLength:0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[webPortFolio appendData:data];
}
-(void) connection:(NSURLConnection *) connection didFailWithError:(NSError *) error
{
NSLog(@"error...................%@",[error description]);
[webPortFolio release];
[connection release];
}
-(void) connectionDidFinishLoading:(NSURLConnection *) connection
{
//Check the request and returns the response.
NSLog(@"DONE. Received Bytes: %d", [webPortFolio length]);
theXMLPortFolio = [[NSString alloc]
initWithBytes: [webPortFolio mutableBytes]
length:[webPortFolio length]
encoding:NSUTF8StringEncoding];
//---shows the XML---
NSLog(@"shows the XML %@",theXMLPortFolio);
[theXMLPortFolio release];
if(xmlParserPortFolio)
{
[xmlParserPortFolio release];
}
xmlParserPortFolio = [[NSXMLParser alloc] initWithData: webPortFolio];
[xmlParserPortFolio setDelegate: self];
[xmlParserPortFolio setShouldResolveExternalEntities:YES];
[xmlParserPortFolio parse];
