据野史记载，开饭日起源于亚洲东方的中国的互联网中生代的白垩纪，由于那时网络处于蛮荒时代，鸭嘴龙横行，吞噬龙间一切能够“自由”活动的东西，直到有一天，发现没有东西可进食，于是集合到一个叫“梅梯”的石头上，以“集体”之力量发出电波，向“背汉”星人友人传达“我们要开饭”的求助信息。背汉星人于是用特快彗星送来食物，不料救友心切，操作出了故障。。。为了纪念当日，网龙们自发地约定用“开饭日”来纪念这天 － 3月23日。 Read more »

Tutorial of kissXML(iPhone)
Posted by xhan on March 25, 2010 3 comments | 306 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!

如题.
文字少了点,贴个图.
PS. wiki系统重新回来了!!(页面右上角的NOTE),这一个多月的时间内被广告攻陷了,今天费了好久才整回来.新增加两个关于MediaWiki的note.
===== 觉得太标题党了点,更新点内容 =========
最近保持了很长一段时间的迷茫,之前做事想来是跟着感觉走,用李开复装逼的方法说就是follow my heart ,决定了也就义无反顾了. 现在发生的事却让我开始怀疑起自己的决定.如何才能做一个好的决定?
过去的一年里认识了3个人.
第一个人推荐了我本书 Programming Game AI by example
第二个人送了我本书 The beauty of code
第三个人推荐了本书 More joel on software
经历了不少,成功的失败的,学到很多.甚至还没来得及给2010年企划,居然已经过去1/4年了.
以后会花更多时间在思考上,而不是鲁莽行事.
