Ok so basically, I am trying to parse a sub-element:
<element>
<sub element 1>
<sub element 2>
<sub element 3>
<element>
The current original document that I want to parse contain as below for example:
sub-element-content1: AB, CD, DE, & SOMETHING DISPLAYED
.
I only managed to grab & SOMETHING DISPLAYED
. I could not parse the whole sub-element.
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
currentNodeContent = (NSMutableString *)[string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
//NSLog(@"CURRENT CONTENT: %@", currentNodeContent);
}
That is the 1st issue. The second issue that I am having is that there are supposed to be 11 items in reference to the above. But it only managed to grab 2 items. Please note that each item contains the sub-elements except that some sub-elements are null
Issues has been added: (null)-(null)-(null)
Issues has been added: sub-element-1 sub-element2 sub-element3
Below is portion of didEndElement
:
if ([elementName isEqualToString:@"Issue"]) {
//add currentIssue object into issues array
[issues addObject:currentIssue];
NSLog(@"Issues has been added: %@-%@-%@", currentIssue.sub-element-1, currentIssue.sub-element-2, currentIssue.sub-element-3);
currentIssue = nil;
currentNodeContent = nil;
}
if ([elementName isEqualToString:@"sub element 1"]) {
currentIssue.sub-element-1 = currentNodeContent;
NSLog(@"sub element 1: %@", currentIssue.sub-element-1);
}
if ([elementName isEqualToString:@"sub element 2"]) {
currentIssue.sub-element-2 = currentNodeContent;
NSLog(@"sub element 2: %@", currentIssue.sub-element-2);
}
if ([elementName isEqualToString:@"sub element 3"]) {
currentIssue.sub-element-3 = currentNodeContent;
NSLog(@"sub element 3: %@", currentIssue.sub-element-3);
}
Your advice(s) and/or suggestion(s) are greatly appreciated.
Update 1:
Ok, I have solved the problem.
It appears that "currentIssue = nil" causes the object to lose its contents as I was able to print out the currentNodeContent.
So, by removing, currentIssue, I am now able to see all the supposed elements that I need.
But there is one more problem. I can see all the sub elements now, but there only one sub element left which was grabbed partially which I do not understand why.
