Fix for nesting issue

[btate]

I've just started using this library and I'm pretty happy with it. The one complaint/suggestion I have is that when I try to nest things, such as

Code: Select all

[TBXML textForElement:[TBXML childElementNamed:@"raceStartState" parentElement:raceNode]];

and the child element I'm looking for isn't there, I get a bad access error when nil is passed to textForElement. I'd like to avoid a ton of conditional statements, so I would suggest adding a line to functions such as textForElement that return an empty string if the element passed in is nil.

Yep that's a great idea!

I'll add that in asap.

Thanks!
