Tutorial of kissXML(iPhone)

Posted by xhan on March 25, 2010 3 comments | 276 views

KissXML is a good approach for parsing xml data, and the x-path function make it more powerful.

Integrate With You Project And KissXML

Download source codes form here
Add all the files to your project (excluding DDXMLTesting)
Configure you project to work with libxml

click Project -> Edit Project Settings

You’ll be adding this to your compiler instructions

OTHER_LDFLAGS = -lxml2

HEADER_SEARCH_PATHS = /usr/include/libxml2

Using KissXML

Here is a quick demo to indicate you how it works.

For example, we need to get the SRC value of each media field from the target xml file.

<smil xmlns="http://www.w3.org/2000/SMIL20/CR/Language">
<head>
</head>
<body>
<par dur="120000ms" >
<text region="Text" src="att000.txt" />
</par>
<par dur="120000ms" >
<text region="Text" src="att010.txt" />
</par>
<par dur="10000ms" >
<img region="Image" src="att020.jpg"/>
</par>
<par dur="120000ms" >
<text region="Text" src="att040.txt" />
</par>
<par dur="10000ms" >
<img region="Image" src="att120.gif"/>
</par>
</body>
</smil>

Here are the codes !

//hack to remove xmlns => avoid xpath search not works
 xmlStr = [xmlStr stringByReplacingOccurrencesOfString:@"xmlns" withString:@"noNSxml"];
 NSMutableArray* contents = [NSMutableArray array];
 NSError* error = nil;
 DDXMLDocument* xmlDoc = [[DDXMLDocument alloc] initWithXMLString:xmlStr options:0 error:&error];
 if (error) {
 NSLog(@"%@",[error localizedDescription]);
 return nil;
 }
 NSArray* resultNodes = nil;
 resultNodes = [xmlDoc nodesForXPath:@"//audio | //text | //image | //img" error:&error];
 if (error) {
 NSLog(@"%@",[error localizedDescription]);
 return nil;
 }
 for(DDXMLElement* resultElement in resultNodes)
 {
 NSString* name = [resultElement name];
 //audio , text or other media type
 NSString* fileName = [[resultElement attributeForName:@"src"] stringValue];
 // 0.txt
 }

Note, I replaced the “xmlns” inside the xml file, because it weird xpath would failed if namespace available at a XML file(it might a bug)

And at last, have fun!

Things I’ve done int past 5 months

It’s awfully to say that Time is running out fast , but it really does.

I’ve been working as a iPhone application developer for five months ,devoting all my energy to my job . Thanks to company’s trust , now I am the core architect and team leader of our small group .

We’ve redesigned most of default iPhone UI components which is really a difficult job at first . After a several days of hardworking ,We released first custom components named ‘MeeTabBarController’ , which is more powerful , flexible, and has ability to manage animations for each tabBar ,each container view’s opening animations and closing animations. It really works great and appears amazing.

Since now We’ve achieved the custom NavigationController, which has more delegate methods , a incredible user interface and animations. the custom alertView , the custom tableViewController , the custom spring board , the custom http-client for fetching remote data , etc .

It would be no exaggeration to say that our custom framework is just another lite version of Three20 .^^

Here is a Preview version of Our Project:

Name	Lines	Files
Third part header	2360	34
Third part Source	4916	38
Project Header	7222	170
Project Source	28330	173
Total	42828	415
Total Pngs		431

Here is a snap shoot of our another application which had submitted to apple store and ready for sale .
It just a simple application that in order to test whether our designs and functions will be rejected or permitted by apple ,Thankfully ,after a mistake that was rejected by undocument api ,It’s status came out to be ready for sale finally.

You can search it by type its name “Grading” ,it’s also based on our custom framework and I cost 3 days to finish it.
Give a try and feel free to comment it !(Note : we put off the sale date of this application for the moment by some conditions)
