structs

[djp_phillips]

I need to use a custom struct, I am trying to parse some XML with NSXMLParser, and my idea is to have a struct like so:

typedef struct {
	NSString *tag;
	NSMutableString *value;
} currentXMLElem;

// this is placed outside the implementation

And I'd initiate one when I get to a desired tag in the XML, and when I come across and characters I'd progressively add them to the value property.

When I get to EndElement, I'd check if there's a "currentCMLElem" variable initiated, if so, clear it

Loop like this until the end of the XML.

But I can't seem to use my struct, here is a sample:

// in didStartElement delegate method:

typedef currentXMLElem currentElem;
currentElem.tag  = @"someTag";

And right there I get the following error:

error: expected identifier or '(' before '.' token

I don't understand what I need, my tag is a property of the struct, and Xcode even autocompletes with the property name "tag".

What could the error be ?


Hope you can help, thanks

A typedef just means an "alias" for your struct name, you need a currentXMLElem variable, declare it like any other type.

currentXMLElem currentElem;
