问题描述
我是iPhone编程的新手，我正在使用NSXmlParser来解析数据并将其存储在一个数组中，但是我想将3个表数据存储在3个不同的数组中，任何人都可以告诉我如何解析数据并将其存储在3个不同的数组中。
I am new to iPhone programming and I am using NSXmlParser to parse the data and store it in an array but I have 3 tables data I want to store that in 3 different arrays, can anybody tell me how can I parse the data and store it in 3 different array.
我的xml看起来像这样
<Result>
<Table diffgr:id="Table1" msdata:rowOrder="0">
<CreatedBy>1</CreatedBy>
<Email>[email protected]</Email>
<SalesAmount>0.0000</SalesAmount>
<PurchasesAmount>0.0000</PurchasesAmount>
</Table>
<Table diffgr:id="Table2" msdata:rowOrder="0">
<CreatedBy>2</CreatedBy>
<Email>[email protected]</Email>
<SalesAmount>0.0000</SalesAmount>
<PurchasesAmount>0.0000</PurchasesAmount>
</Table>
<Table diffgr:id="Table3" msdata:rowOrder="0">
<CreatedBy>3</CreatedBy>
<Email>[email protected]</Email>
<SalesAmount>0.0000</SalesAmount>
<PurchasesAmount>0.0000</PurchasesAmount>
</Table>
</Result>
使用下面的代码，我可以将所有已解析的数据存储在一个数组中。
Using below code I am able to store all parsed data in one array.
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
attributes: (NSDictionary *)attributeDict
{
arr_info=[NSMutableArray arrayWithObjects:@"CreatedBy",@"Email",@"SalesAmount",@"PurchasesAmount",nil];
for (i=0; i<[arr_info count]; i++)
{
if( [elementName isEqualToString:[arr_info objectAtIndex:i]])
{
if(!soapResults)
{
soapResults = [[NSMutableString alloc] init];
}
xmlResults = YES;
}
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if( xmlResults )
{
[soapResults appendString: string];
NSLog(@"soap result %@",soapResults);
[arr_detail addObject:soapResults];
NSLog(@"gg %@",arr_detail);
}
[tableView reloadData];
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
for (i=0; i<[arr_info count]; i++)
{
if( [elementName isEqualToString:[arr_info objectAtIndex:i]])
{
xmlResults = FALSE;
switch ([arr_detail count]) {
case 1:
l1.text=[arr_detail objectAtIndex:[arr_detail count]-1];
NSLog(@"%@",[arr_detail objectAtIndex:[arr_detail count]-1]);
break;
case 2:
l2.text=[arr_detail objectAtIndex:[arr_detail count]-1];
NSLog(@"%@",[arr_detail objectAtIndex:[arr_detail count]-1]);
break;
case 3:
l3.text=[arr_detail objectAtIndex:[arr_detail count]-1];
NSLog(@"%@",[arr_detail objectAtIndex:[arr_detail count]-1]);
break;
case 4:
l4.text=[arr_detail objectAtIndex:[arr_detail count]-1];
NSLog(@"%@",[arr_detail objectAtIndex:[arr_detail count]-1]);
break;
}
[tableView reloadData];
soapResults = nil;
}
}
}
推荐答案
你可以使用xmlReader来轻松处理。这是文件
you can use xmlReader that will make it easy to handle.Here is the files
和
这是代码
NSString *xmlString=@"<Result><Table diffgr:id=\"Table1\" msdata:rowOrder=\"0\"><CreatedBy>1</CreatedBy><Email>[email protected]</Email><SalesAmount>0.0000</SalesAmount><PurchasesAmount>0.0000</PurchasesAmount></Table><Table diffgr:id=\"Table2\" msdata:rowOrder=\"0\"><CreatedBy>2</CreatedBy><Email>[email protected]</Email><SalesAmount>0.0000</SalesAmount><PurchasesAmount>0.0000</PurchasesAmount></Table><Table diffgr:id=\"Table3\" msdata:rowOrder=\"0\"><CreatedBy>3</CreatedBy><Email>[email protected]</Email><SalesAmount>0.0000</SalesAmount><PurchasesAmount>0.0000</PurchasesAmount></Table></Result>";
NSDictionary *dics=[[NSDictionary alloc]initWithDictionary:[XMLReader dictionaryForXMLString:xmlString error:nil]];
NSLog(@"dics is %@",dics);
NSArray *tableDicsArray=[[dics valueForKey:@"Result"] valueForKey:@"Table"];
这是你的输出------------
And here is your output------------
dics is {
Result = {
Table = (
{
CreatedBy = {
text = 1;
};
Email = {
text = "[email protected]";
};
PurchasesAmount = {
text = "0.0000";
};
SalesAmount = {
text = "0.0000";
};
"diffgr:id" = Table1;
"msdata:rowOrder" = 0;
},
{
CreatedBy = {
text = 2;
};
Email = {
text = "[email protected]";
};
PurchasesAmount = {
text = "0.0000";
};
SalesAmount = {
text = "0.0000";
};
"diffgr:id" = Table2;
"msdata:rowOrder" = 0;
},
{
CreatedBy = {
text = 3;
};
Email = {
text = "[email protected]";
};
PurchasesAmount = {
text = "0.0000";
};
SalesAmount = {
text = "0.0000";
};
"diffgr:id" = Table3;
"msdata:rowOrder" = 0;
}
);
};
}
如果您使用ARC，请不要忘记禁用arc 。
---------------为每个表使用词典.-------
---------------Use dictionaries for each table.-------
NSDictionary *tbl1= [tableDicsArray objectAtIndex:0];
NSDictionary *tbl2= [tableDicsArray objectAtIndex:1];
NSDictionary *tbl3= [tableDicsArray objectAtIndex:2];
NSArray *tbl1Keys=[[tbl1 allKeys] sortedArrayUsingSelector:@selector(compare:)];
NSArray *tbl2Keys=[[tbl2 allKeys] sortedArrayUsingSelector:@selector(compare:)];
NSArray *tbl3Keys=[[tbl3 allKeys] sortedArrayUsingSelector:@selector(compare:)];
//you can use these keys to pass no of rows in you table.
//and use dictionary in cellforRow as give below:-------
NSString *key=[tbl1Keys objectAtIndex:indexPath.key];
cell.textLabel.text=[tbl1 valueForKey:key];
