NSXML解析器拆分 XML TAG 值

Question

我有以下来自网络服务的 XML 数据：

<ROWS>
<ROW>
<GroupBy>1</GroupBy>
<QUERY>
INSERT INTO TASKS_GVT([PK],[TaskYear],[TaskTypeId],[TaskElementType],[TaskPriority],[ElementId],[taskstatus],[TaskSubStatus],[AllocatedteamId],[PreRequisiteTask], [xloc],[yloc],[X],[Y],[Address],[TaskZone],[taskread],[clientid],[distance],[lastdistcalcdt],[ReplicateMe],[AllocationRequestTime]) VALUES ('3179543',2014,'19','1','2','107-08-106_421','3','6','380','0','0.0000000','0.0000000','44.4144000','24.5186000','الدوادمي ','421-0-0','R','0','0',GETDATE(),0,GETDATE())
</QUERY>
</ROW>
<ROW>
<GroupBy>2</GroupBy>
<QUERY>
INSERT INTO RPTProblemTypes_GVT ([TaskYear] ,[TaskCode] ,[pbTypeId] ,[ReportDate] ,[INSTANCENAME] ,[PK] ,[ParentId] ) VALUES ('2015','3179543','754','Sep 11 2015 11:11AM','1-1086','380-1','1086')
</QUERY>
</ROW>
<ROW>
</ROWS>

我正在使用 NSXMParser 读取 Web 服务响应，如下所示：

let parser = NSXMLParser (data: data!) //data is fetched using alamofire

委托方法：

public func parser(parser: NSXMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String])
{
    tagElement=elementName
}

public func parser(parser: NSXMLParser, foundCharacters string: String)
{

     if (tagElement.uppercaseString == "QUERY")
        {
            dataReturned+=string;
            print ("here dataReturned: \(string)")
        }
}
public func parser(parser: NSXMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?)
{
}

我的输出是：

here dataReturned: INSERT INTO TASKS_GVT([PK],[TaskYear],[TaskTypeId],[TaskElementType],[TaskPriority],[ElementId],[taskstatus],[TaskSubStatus],[AllocatedteamId],[PreRequisiteTask],
here dataReturned: 
 [xloc],[yloc],[X],[Y],[Address],[TaskZone],[taskread],[clientid],[distance],[lastdistcalcdt],[ReplicateMe],[AllocationRequestTime]) VALUES ('3179543',2014,'19','1','2','107-08-106_421','3','6','380','0','0.0000000','0.0000000','44.4144000','24.5186000','
here dataReturned: الدوادمي ','421-0-0','R','0','0',GETDATE(),0,GETDATE()) 
here dataReturned: 
here dataReturned: INSERT INTO RPTProblemTypes_GVT ([TaskYear] ,[TaskCode] ,[pbTypeId] ,[ReportDate] ,[INSTANCENAME] ,[PK] ,[ParentId] ) VALUES ('2015','3179543','754','Sep 11 2015 11:11AM','1-1086','380-1','1086')

如您所见，我只对检索标签QUERY感兴趣，但输出是错误的！标签值正在拆分（即 foundCharacters 方法在同一个标签上被多次调用）请有人帮我解决这个问题。

我注意到只有当标签中有阿拉伯字母时才会出现这种情况。！！！

谢谢

对于使用 NSXMLParser 有困难的任何人，请使用 SWXMLHash，这显然是一种简单且更好的方法

https://github.com/drmohundro/SWXMLHash

我最后做了这样的事情：

let xml = SWXMLHash.lazy(ReturnedData)

let Queries = (xml["ROWS"]["ROW"].all.map { elem in elem["QUERY"].element!.text;})

for Query in Queries
{
  print (Query)
}
