So, after discussing some methods to import and export a CoreData database, I
ended up sticking with my initial XML idea.
Now I'm stuck in a problem when parsing that is probably simple, but I can't
solve. Basically, my XML is like this:
<elem1>
<child1>Value</child1>
<child2>Value</child2>
<child3>Value</child3>
</elem1>
<elem2>
<child1>Value</child1>
<child2>Value</child2>
<child3>Value</child3>
</elem2>
When parsing with NSXMLParser, everything runs properly (well, almost) except
for the fact that every property (child elements here) from every entity (elem
here) gets the value from the last imported property, child3 in this case.
For me, that means my currentEntity ivar is keeping track of every entity
created, in some way that I probably just managed to do due to little CoreData
knowledge.
Here is the main code:
-(void)parser: ... didStartElement: {
...
// Entity
if ([elementName isEqualToString:kEntityContent]) {
if (currentEntity) [currentEntity release]; // currentEntity is an ivar
currentEntity = [[NSEntityDescription
insertNewObjectForEntityForName:kContent
inManagedObjectContext:managedObjectContext]
retain];
return;
}
// Attribute
if ([elementName isEqualToString:kAttrName]) {
[currentXMLValue setString:@""]; // currentXMLValue is another ivar
return;
}
...
}
-(void)parser: foundCharacters:(NSString *)string {
[currentXMLValue appendString:string];
}
-(void)parser: ... didEndElement {
// Database - Save the Import
if ([elementName isEqualToString:@"database"]) {
NSError *error;
if (![self.managedObjectContext save:&error]) {
NSLog(@"There was an error while saving "
"the imported database: %@", error);
}
}
// Attribute
if ([elementName isEqualToString:kAttrName]) {
[currentEntity setValue:currentXMLValue forKey:kAttrName];
return;
}
...
}
Thanks in advance for any help.
