TBXML解析複雜的XML到數組

Question

我有一個XML響應，我需要設置到一個數組。問題是我需要訪問每個元素並將其存儲在一個數組中，以便我可以將它用於tableview。

<?xml version="1.0" encoding="UTF-8"?> 
<Response xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://schema.2sms.com/2.0/schema/0310_ResponseReportStandard.xsd" Version="1.0"> 
    <Error> 
     <ErrorCode>00</ErrorCode>

    </Error> 
    <ResponseData>

     </Identification> 
     <Result>2 records were returned</Result> 
     <Detail> 
      <ReportTitle>Message Summary: Today</ReportTitle> 
      <Record> 
       <Destination>447790686158</Destination> 
       <Status>WithNetwork</Status>

     </Detail> 
    </ResponseData> 
</Response> 

我有TBXML對象初始化但不能工作如何得到任何的重複信息，我知道這將需要某種形式的循環，但我是很新，Objective-C的所以它的證明一個挑戰。我需要從xml中獲取<destination> , <status>, <datesent>, <message>。可以有多達25條記錄....

希望有人能幫助這一直在我的腦海中整天！

我做了類似的事情最近，你能很快適應，我的XML是：

<?xml version="1.0" encoding="ISO-8859-1"?> 
<agencies> 
    <agency> 
     <name>Agency 1 name</name> 
     <addressFirstLine>Immeuble XYZ<addressFirstLine> 
     <addressSecondLine>rue de la republique</addressSecondLine> 
     <addressThirdLine>69007 Lyon</addressThirdLine> 
     <telNumber>01 23 45 67 89</telNumber> 
    </agency> 
    <agency> 
     <name>Agency 2 name</name> 
     <addressFirstLine>Immeuble ABC<addressFirstLine> 
     <addressSecondLine>rue de la republique</addressSecondLine> 
     <addressThirdLine>69007 Lyon</addressThirdLine> 
     <telNumber>01 23 45 67 89</telNumber> 
    </agency> 
</agencies> 

的代碼我用來分析這一（獲得的結果在我的NSArray稱爲agencies）：

TBXML *tbxml = [[TBXML tbxmlWithXMLFile:yourXmlFile retain]; 
    TBXMLElement *rootXMLElement = tbxml.rootXMLElement; 

    if (rootXMLElement) { 
     self.agencies = [self traverseElement:rootXMLElement]; 
     [delegate managerDidReceiveData]; 
    } 

    // release resources 
    [tbxml release]; 

我的功能轉換爲：

- (NSArray *)traverseElement:(TBXMLElement *)element { 

    NSMutableArray *tmpAgencies = [[NSMutableArray alloc] init]; 

    TBXMLElement *agenciesXmlElement = element->firstChild; 
    TBXMLElement *agencyXmlElement; 

    do { 

     // if the element has child elements, process them 
     if ((agencyXmlElement = agenciesXmlElement->firstChild)) { 

      NSMutableDictionary *tmpAgency = [[NSMutableDictionary alloc] init]; 

      do { 
       [tmpAgency setValue:[TBXML textForElement:agencyXmlElement] forKey:[TBXML elementName:agencyXmlElement]]; 

      // Obtain next sibling element 
      } while ((agencyXmlElement = agencyXmlElement->nextSibling)); 

      [tmpAgencies addObject:tmpAgency]; 
      [tmpAgency release]; 
     } 

    // Obtain next sibling element 
    } while ((agenciesXmlElement = agenciesXmlElement->nextSibling)); 

    return tmpAgencies; 
} 

Thi s函數會返回一個數組，其中包含代表您的Records的NSDictionary對象。 NSDictionary使用簡單，獲得您使用的財產[yourDictionary objectForKey:yourXmlNode]。該文檔位於：NSDictionary。
