RaptureXML无法从用户路径加载数据

Question

I'm new to iOS development. I've found RaptureXML and it works quiet well but I could not load data which I stored in my user directory. Having a "data.xml" within my application directory works fine, I could load it with [RXMLElement elementFromXMLFile:@"data.xml"]; . But now I have downloaded a file from Internet and stored it in my user directory using these lines:

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *filePath = [NSString stringWithFormat:@"%@/%@", [paths objectAtIndex:0],@"data.xml"];

The computed file path is

"/Users/ myname /Library/Application Support/iPhone Simulator/6.0/Applications/ myapplicationguid /Documents/data.xml"

.

The file exists, I've checked with [[NSFileManager defaultManager] fileExistsAtPath:filename]; . I've also opened it manually and placed the value from the example XML File from RaptureXML there, so it could not be any mismatches within the XML or else....

But when I use [RXMLElement elementFromXMLFile:filename] it does not return anything... Any ideas?

I've now made a workaround: As direct access does not work, I'm first loading the data using standard functions and then transfer the NSData to RaptureXML like this:

 NSError *error;
    NSString* contents = [NSString stringWithContentsOfFile:filename
                                                   encoding:NSUTF8StringEncoding
                                                      error:&error];
    NSData* xmlData = [contents dataUsingEncoding:NSUTF8StringEncoding];

    RXMLElement *rss = [RXMLElement elementFromXMLData:xmlData];

最好使用initFromXMLFilePath：方法。

 RXMLElement *rss = [[RXMLElement alloc]initFromXMLFilePath: filePath];
