我正在尝试解析来自Web服务器的响应。
我的解析器执行如下操作:
#import "XMLParser.h"
#import "AppDelegate.h"
#import "Child.h"
@implementation XMLParser
- (XMLParser *) initXMLParser {
self = [super init];
if(self)
{
appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
}
return self;
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
attributes:(NSDictionary *)attributeDict
{
if([elementName isEqualToString:@"GetKidsResult"])
{
// initialize the array
if(!appDelegate.children)
{
appDelegate.children = [[NSMutableArray alloc] init];
}
}
else if([elementName isEqualToString:@"a:KeyValueOfintKidf4KEWLbb"])
{
if(!aChild)
{
//Initialize the child.
aChild = [[Child alloc] init];
}
}
NSLog(@"Processing Element: %@", elementName);
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
if(!currentElementValue)
{
currentElementValue = [[NSMutableString alloc] initWithString:string];
}
else
{
[currentElementValue appendString:string];
}
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
//NSLog(@"El name: %@", elementName);
if([elementName isEqualToString:@"GetKidsResult"])
NSLog(@"end of xml");
return;
if([elementName isEqualToString:@"a:KeyValueOfintKidf4KEWLbb"])
{
NSLog(@"Found end of child");
[appDelegate.children addObject:aChild];
aChild = nil;
}
else if([elementName isEqualToString:@"a:Key"])
{
NSLog(@"Found key");
}
else if([elementName isEqualToString:@"b:CheckedIn"])
{
NSLog(@"Found checkedIn");
}
else if([elementName isEqualToString:@"b:FirstName"])
{
NSLog(@"Found firstname");
}
else if([elementName isEqualToString:@"b:Gender"])
{
NSLog(@"found gender");
}
else if([elementName isEqualToString:@"b:Id"])
{
NSLog(@"found id");
}
else if([elementName isEqualToString:@"b:IsOnTour"])
{
NSLog(@"found isontour");
}
else if([elementName isEqualToString:@"b:LastName"])
{
NSLog(@"found lastname");
}
else if([elementName isEqualToString:@"b:GroupName"])
{
NSLog(@"found groupname");
}
currentElementValue = nil;
}
@end
现在我只是想看看它是否找到了数据......然后我会保存它...... 但是在我的didEndElement中,它似乎找不到除
之外的任何东西if([elementName isEqualToString:@"GetKidsResult"])
我的xml响应示例:
<a:KeyValueOfintKidf4KEWLbb>
<a:Key>XXXXXXXX</a:Key>
<a:Value xmlns:b="http://schemas.datacontract.org/2004/07/DayCare.DB.DTO">
<b:CheckedIn>false</b:CheckedIn>
<b:FirstName>XXXXXXX</b:FirstName>
<b:Gender>Male</b:Gender>
<b:Id>XXXXXXXX</b:Id>
<b:IsOnTour>false</b:IsOnTour>
<b:LastName>XXXXXX</b:LastName>
<b:Photo>XXXXXXXX</b:Photo>
<b:GroupName>XXXXX</b:GroupName>
</a:Value>
</a:KeyValueOfintKidf4KEWLbb>
任何想法为什么它不是其他元素? 我之前从未做过Web服务,所以解释越简单越好......
当我NSLog元素时,我可以看到它正确地通过xml文件
NSLog(@"Processing Element: %@", elementName);
示例:
Processing Element: a:KeyValueOfintKidf4KEWLbb
Processing Element: a:Key
Processing Element: a:Value
Processing Element: b:CheckedIn
Processing Element: b:FirstName
Processing Element: b:Gender
Processing Element: b:Id
Processing Element: b:IsOnTour
Processing Element: b:LastName
Processing Element: b:Photo
Processing Element: b:GroupName
答案 0 :(得分:3)
在didEndElement
中,尝试更改此部分:
if([elementName isEqualToString:@"GetKidsResult"])
NSLog(@"end of xml");
return;
为:
if([elementName isEqualToString:@"GetKidsResult"])
{
NSLog(@"end of xml");
return;
}
如果不在块if
之后放置这两个语句,return
每次都会执行。
