我做了一个web服务,它的工作原理,问题是与web服务响应。 我有这个XML(我想解析touchxml),问题是与touchxml,它发现两个XML,一个在另一个里面,它使崩溃。 这是我的问题,我如何解析这个XML?我怎么可以去除所有的东西,如SOAP-ENV,XMLNS ....解析肥皂响应问题(iphone/touchxml)

<?xml version="1.0" encoding="ISO-8859-1"?> 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body> 
<ns1:getCategoriesResponse xmlns:ns1="http://192.168.1.30/wyws/server.php"><return xsi:type="xsd:string"> 

    <?xml version="1.0" encoding="UTF-8"?> 
    <categories> 
     <category id="1" desc="Encontrar Códigos " icon="wy">Código </category> 
     <category id="3" desc="" icon="farm">Far</category> 
     <category id="5" desc="" icon="gas">Gas</category> 
     <category id="6" desc="" icon="hos">Hos</category> 
     <category id="7" desc="" icon="pol">Pol</category> 
    </categories> 

</return></ns1:getCategoriesResponse></SOAP-ENV:Body></SOAP-ENV:Envelope> 

这是我如何拨打电话:

NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url]; 
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]]; 
[theRequest addValue:@"8bit" forHTTPHeaderField:@"Content-Transfer-Encoding"]; 
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 
[theRequest addValue: @"getCategories" forHTTPHeaderField:@"SOAPAction"]; 

[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"]; 
[theRequest setHTTPMethod:@"POST"]; 
[theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; 

NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; 

webData = [[NSMutableData data] retain]; 

然后

-(void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 

    NSLog(@"DONE. Received Bytes: %d", [webData length]); 

    NSString *theXML = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSISOLatin1StringEncoding]; 


NSLog(theXml); 
.... 
}

我写的这不是很优雅,但它的工作原理。

NSRange in = [tmpTheXml rangeOfString:@"<return xsi:type=\"xsd:string\">"]; 
NSRange fi = [tmpTheXml rangeOfString:@"</return>"]; 
int inic = in.location + in.length; 
NSRange tmprange = {inic,fi.location - inic} ; 
tmpTheXml = [tmpTheXml substringWithRange:tmprange];
