I've got an NSXMLDocument *custdoc

I just can't work out the correct code.
sample xml:

How can I set an NSString *firstName to the value?
I appreciate any help,
Many Thanks

If you are working with Hillegass's example he is putting the XPath
path in the identifier of the table column and uses it in the
tableView:objectValueForTableColumn:row: data source method. In
your example above the path would be "sesbuddycustimport/customer/
first_name"
If you are working with the NSXMLDocument programatically then you
need to call the nodesForXPath:error: method yourself. I would
separate the individual customer items into an array first then you
can get any info about any customer. Also keep in mind that
NSXMLDocument is a subclass of NSXMLNode so you can call NSXMLNode
methods on it.
(warning, typed into mail)
NSArray *customerArray = [custdoc nodesForXPath:@".//customer"
error:nil];
if ([customerArray count) {
for (NSXMLNode *customerNode in customerArray) {
NSArray *firstNameArray = [[customerNode nodesForXPath:@".//
first_name" error:nil];
if ([firstNameArray count]) {
NSString *firstNameString = [firstNameArray objectAtIndex:0]
stringValue];
// do something with the first name string
}
// get other strings
...
// do something with the other strings
...
}
}
There are other methods of getting info out of an NSXMLDocument (or
XML data in general), but this is how I usually approach it. You
didn't mention what you wanted to do with the string.
Hope this helps,

Overall I want to extract the data from the XML file, and create new
instances of CoreData Entities with it.
I seem to keep getting errors along the lines of NSArray / NSString /
NSXMLNode may not respond to -nodesForXpath / stringForPath:ofNode:
It's already in a loop, and
printf( "Customer: %s\n", [[obj description] cString] );
correctly print out the correct line,
Customer: <customer><first_name>Willow</first_name><last_name>Tree
Crafts</last_name><address_1>99 Leggatts Way</address_1><city>Herts</
city><zip>WD24 5NQ</zip><country>GBR</
country><user_email>[EMAIL PROTECTED]</user_email></customer>
I just don't seem able to get the individual data,
Many Thanks
