我收到了XML格式的Web服务调用的响应。我想在XML响应中搜索status
字符串,并根据其值继续进行。我怎样才能做到这一点?回复如下:
<META NAME="ColdFusionMXEdition" CONTENT="ColdFusion DevNet Edition - Not for Production Use."><?xml version="1.0" encoding="UTF-8"?>
<ParticipantService>
<Response>
<student_id>10082</student_id>
</Response>
<RequestStatus>
<Code>1</Code>
<Status>SUCCESS</Status>
<Message>Valid Credentials.</Message>
</RequestStatus>
</ParticipantService>

您可以使用NSXmlParser。如果您只检查状态,可以按如下方式进行字符串操作,
NSString *mystring = @"<Response><status>SUCCESS</status> </Response>";
NSString *neededString = nil;
NSScanner *scanner =[NSScanner scannerWithString:mystring];
[scanner scanUpToString:@"<status>" intoString:NULL];
[scanner scanString:@"<status>" intoString:NULL];
[scanner scanUpToString:@"</status>" intoString:&neededString];
NSLog(@"%@",neededString);
if ([neededString isEqualToString:@"SUCCESS"]){ //do what you like. }

您是否可以在开发库中访问XPath?
如果是这样,你可以使用(例如);
if (myDoc.xPath('/RequestStatus[Status = "SUCCESS"]').size() > 0) { }
