一个解析XML数据的简单Demo（以KissXml为例）

1、添加附件里面的KissXML到工程

2、加入libxml2.dylib 到Frameworks

3、修改工程信息，右击Targets下工程名选“Get Info”，进入修改Header Search Paths值为：/usr/include/libxml2，如附件图

附件2为Demo，可运行。

PS:本Demo是以解析本地数据为例，解析网页数据可用：

NSString *content = [NSString stringWithContentsOfURL: url

encoding:NSUTF8StringEncoding

error:&error];

[string release];

[self parsedDataFromString:content];

}

-(void)parsedDataFromString:(NSString *)str{

[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];

DDXMLDocument *doc = [[DDXMLDocument alloc] initWithXMLString:str opti*****:0 error:nil];

/////解析

NSArray *items = [doc nodesForXPath:kXML error:nil];



for (DDXMLElement *obj in items) {

xmlData *data = [[xmlData alloc] init];



DDXMLElement *aUser = [obj elementForName:KUSER];

if(aUser)

data.user = aUser.stringValue;

DDXMLElement *aTitle = [obj elementForName:KTITLE];

if(aTitle)

data.title = aTitle.stringValue;

DDXMLElement *content = [obj elementForName:KCONTENT];

if(content)

data.content = content.stringValue;

NSDictionary *XmlDictionary;

XmlDictionary = [NSDictionary dictionaryWithObjectsAndKeys:

data.user,@"kUsers",

data.title,@"kTitles",

data.content,@"kContents",

nil];

[self performSelectorInBackground:@selector(parsedXml:) withObject:XmlDictionary];

[data release];

}

[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];

[doc release];

}
