如何使用GDataXML解析器解析嵌套的xml？

Question

我怎樣才能得到這個<firstName>和<lastName>。我嘗試了很多，但我已經搞砸了。

<list> 
<OrderData HASH="1843180441"> 
<id>26</id><customer> 
    <CustomerData HASH="882063912"> 
    <id>1</id> 
    <sex>Male</sex> 
    <firstName>admin</firstName> 
    <lastName>admin</lastName> 
    <companyName>Individual</companyName> 
    <userName>admin</userName> 
    <password>21232f297a57a5a743894a0e4a801fc3</password>  
    <lastLogin>2012-01-26T12:11:38</lastLogin> 
    <status>A</status> 
    <created>2011-09-28T07:01:47</created> 
    <modified>2012-01-26T12:11:38</modified> 
    <canChangePassword>Y</canChangePassword> 
    <isDeleted>false</isDeleted> 
    <abn/> 
    <abnBranch/> 
<storeCredit>50000.0</storeCredit> 
<billingAddress> 
<list> 
<AddressData HASH="768553743"> 
    <id>2</id> 
    <firstName>admin</firstName> 
    <lastName>admin</lastName> 
    <addressLine1>suite: 1307, 9 Yara Street</addressLine1> 
    <addressLine2>dgdgdf</addressLine2> 
    <postCode>3000</postCode> 
    <suburb>dfgdfg</suburb> 
    <city>sadf</city> 
    <phone>4456</phone> 
    <mobile/> 
    <fax/> 
    <active>true</active> 
    <type>C</type> 
    <email>afzal.bitmascot@gmail.com</email> 
    <log/> 
</AddressData> 
</deliveryAddress> 
<purchaseDate>2011-10-03T03:23:48</purchaseDate> 

</OrderData> 
<OrderData HASH="1569451006"></OrderData> 
<OrderData HASH="1449383081"></OrderData> 
<OrderData HASH="1438157618"></OrderData> 
<OrderData HASH="269308788"></OrderData> 
</list> 

直到現在我已經做到了。

NSLog(@"Enering in the xml file"); 
NSArray *getNumberOfOrder = [[xmlDocument rootElement] elementsForName:@"OrderData"]; 

for(GDataXMLElement *e in getNumberOfOrder){ 
    for(int i =0;i<[[e elementsForName:@"customer"]count];i++){ 
     // All orderd customer name 
     NSString *orderByFirstString = [[[[e elementsForName:@"customer"] objectAtIndex:0] childAtIndex:2] stringValue]; 
     NSString *orderByLastString = [[[[e elementsForName:@"customer"] objectAtIndex:0] childAtIndex:3]stringValue]; 
     orderByString = [NSString stringWithFormat:@"%@ %@",orderByFirstString,orderByLastString]; 
     NSLog(@"order By String: %@",orderByString); 
     } 
} 

非常感謝您的任何幫助或建議。

我會嘗試這樣的事情。我將遍歷XML文檔，並將其存儲在一個數組中。

注意NSLog（）將打印到控制檯，並將幫助您看到發生了什麼。

xmlDocument = [[GDataXMLDocument alloc]initWithData:xmlData options:0 error:nil]; 

NSArray *temp = [xmlDocument.rootElement elementsForName:@"OrderData"]; 

for(GDataXMLElement *e in temp) { 
    [outputArray addObject:e]; 
    NSLog(@"%@", e); 
} 

然後我會通過數組循環，做這樣的事情時，我想檢索結果，如客戶的名字。

for (int i = 0; i < [outputArray count]; i++) { 
    NSString *firstName = [[[[[[[[outputArray objectAtIndex:i]elementsForName:@"customer"] objectAtIndex:0] elementsForName:@"CustomerData"] objectAtIndex:0] childAtIndex:2]stringValue]; 
}
