KissXML类库的使用方法

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。

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 options: 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];
}
