不使用分析程序在XMLNSString中提取值

string如下：

<?xml version="1.0" encoding="utf-8"?>
<NewDataSet>
  <Table>
    <CITY>Jupiter</CITY>
    <STATE>FL</STATE>
    <ZIP>33477</ZIP>
    <AREA_CODE>561</AREA_CODE>
    <TIME_ZONE>E</TIME_ZONE>
  </Table>
</NewDataSet>

我想要获取其中的city，也就是Jupiter，但是不用xml分析器，有没有简捷的方法实现？

NSArray *array = [yourXMLString componentsSeparatedByString:@"CITY"];
NSString *city = [[array objectAtIndex:1] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"></"]];

其实还是分析器好用点

NSString* str=[[NSString alloc]initWithContentsOfFile: FILENAME encoding: NSUTF8StringEncoding error: nil];
NSLog(@"%@",str);
NSRange range1= [str rangeOfString: @"<CITY>"];
NSRange range2= [str rangeOfString: @"</CITY>"];
NSUInteger location= range1.location+range1.length;
NSUInteger length= range2.location-range1.location-range1.length;
NSString* substr= [str substringWithRange: NSMakeRange(location,length)];
NSLog(@"%@",substr);
