Question

I’m traying to extract info from a table made in xml, here is an example of mi file testXML.xml, it is inside the app:

<response>
<responseCode>0</responseCode>

<rows>
    <row>
        <user>1969-01-01</user>
        <score>1.5434126596E-2</score>
    </row>
    <row>
        <user>1969-02-01</user>
        <score>1.5489521629000001E-2</score>
    </row>
    <row>
        <user>1969-03-01</user>
        <score>1.5504809914E-2</score>
    </row>   < /rows>   </response>

what I’m trying to do is, to write in a text field the user, search it in the xml and display the score from the same row in a label. help please :S

Answer 1

ok…so i suggest to use a NSDictionary instead

NSMutableDictionary *dict = [[NSMutableDictionary alloc]  init];
[dict setObject:@"score1" forKey:@"user1"]; //to set data in the dictionary
.....

to get data from dict:

[dict objectForKey:@"user1"];

to save to file:

[dict writeToFile:[[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"dictionary"] atomically:YES];

to read from file:

NSMutableDictionary *dict =[NSMutableDictionary dictionaryWithContentsOfFile:[[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"dictionary"]];

its easyer..it searches automatically, its fast

i dont see why you would use a xml over a dictionary in this case
