我正在使用iPhone中的Web服務並通過NSXMLParser解析它。我的服務返回對象數組，但是當我從Web服務獲取它並連接相同類型的值時。 Web服務生成以下響應。iPhone：如何通過網絡服務獲得數組值？
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GetClientTripsResponse xmlns="http://tempori.net/">
<GetClientTripsResult>
<TripNumbers>
<ConfirmationsNumber>string</ConfirmationsNumber>
<TripState>string</TripState>
</TripNumbers>
<TripNumbers>
<ConfirmationsNumber>string</ConfirmationsNumber>
<TripState>string</TripState>
</TripNumbers>
</GetClientTripsResult>
</GetClientTripsResponse>
</soap:Body>
</soap:Envelope>
對於ConfirmationsNumber爲6位數字，TripState是字符串值NONE或歐維
但是，當我解析它給出
ConfirmationsNumber = 234589455623784523和
TripState = NONENONEONWAY
意味着它解析三個對象並連接它們。我想要隔離的值或至少逗號分隔。像234589,455623,784523或者什麼都應該是可拆分的。
下面是代碼
