iOS第三方HTML解析 TFHpple 的简单使用

准备工作

1.导入TFHpple 2.引入静态库文件libxml2.2.dylib 3.PROJECT 中的 Search Path - header search paths添加 /usr/include/libxml2

解析步骤

1.初始化data 2.根据data创建TFHpple实例 3.查找节点存入数组 4.在该节点下 循环查找子节点

Object-C代码：

NSData *htmlData = [[NSData alloc]initWithContentsOfURL:[NSURL URLWithString:@"http://www.xxx.com/xxxx?x=1"]];

TFHpple *xpathParser = [[TFHpple alloc]initWithHTMLData:htmlData];

pragma mark 每页主题
NSArray *itemArray = [xpathParser searchWithXPathQuery:@"//div[@class = 'cell item']"];

//通过for in 在itemArray数组中 循环查找子节点 for (TFHppleElement *hppleElement in itemArray) {

/** 这段被正则表达代替 @"//div[@class = 'cell item']"] if ([[hppleElement objectForKey:@"class" ] isEqualToString:@"cell item"]) { [self.allDataMutableArray addObject:hppleElement]; } /

pragma mark 子节点头像
NSArray *IMGElementsArr = [hppleElement searchWithXPathQuery:@"//img"];
for (TFHppleElement *tempAElement in IMGElementsArr) {
NSString *imgStr = [tempAElement objectForKey:@"src"];
NSString *subStr = [@"http:" stringByAppendingString:imgStr];
[self.avatarMutableArray addObject:subStr];
}
pragma mark 子节点标题/链接
NSArray TitleElementArr = [hppleElement searchWithXPathQuery:@"//span[@class='item_title']"]; for (TFHppleElement tempAElement in TitleElementArr) { //获得标题 NSString *titleStr = [tempAElement content];

//1.获得子节点（正文连接节点） 2.获得节点属性值 3.加入到字典中
NSArray * arr = [tempAElement children];
TFHppleElement *href = arr.firstObject;
NSString * titleHrefStr = [href objectForKey:@"href"];

[self.allDataMutableDict setObject:titleStr forKey:@"title"];
self.allDataMutableDict[@"titleHref"] = titleHrefStr;

}
pragma mark 子节点fade
//简化写法 简化3步
NSArray *nodeElementArr = [hppleElement searchWithXPathQuery:@"//a[@class='node']"];
self.allDataMutableDict[@"node"] = [nodeElementArr.firstObject content];

NSArray *fadeElementArr = [hppleElement searchWithXPathQuery:@"//span[@class = 'small fade']"];
NSArray *subArray = [ [fadeElementArr.firstObject content] componentsSeparatedByString:@" • "];

self.allDataMutableDict[@"louZhu"] = [subArray objectAtIndex:1];
self.allDataMutableDict[@"lastTime"] = [subArray objectAtIndex:2];
pragma mark 子节点回复数
NSArray * repeatElementArr = [hppleElement searchWithXPathQuery:@"//a[@class = 'count_livid']"];
if ([repeatElementArr.firstObject content ]) {
self.allDataMutableDict[@"repeatCount"] = [repeatElementArr.firstObject content];
}else{
self.allDataMutableDict[@"repeatCount"] = [NSString stringWithFormat:@"%d",0];
}
pragma mark 转化model 存进数组
[model setValuesForKeysWithDictionary:self.allDataMutableDict];
[self.allDataMutableArray addObject:model];
}
