How to use NSXMLParser?

问题:

I have some XML which I need parsed in my Objective-C code. The XML is fairly simple. I have already searched Stackoverflow as well as Google but I did not find what I am looking for. Examples if how to use NSXMLParser would be useful, and if anyone has any suggestions on how to do this another way please let me know.

回答1:

Did you look at the Apple sample applications? From the NSXMLParser class reference, I found no fewer than five sample projects that did parsing.

• GKTank
• KMLViewer
• LazyTableImages
• SeismicXML (probably your best bet, and most directly related)
• XMLPerformance

I recommend going through this tutorial by Ray Wenderlich:
http://www.raywenderlich.com/725/how-to-read-and-write-xml-documents-with-gdataxml

It uses GDataXML, which from my experience is a light-weight easy to use XML parser. It goes through all the basic steps to read and write to an XML document in a specific directory, including making or ammending to the file if it doesnt exist or exists respectively.
