ios中xml和html解析（封装）

下载地址  http://pan.baidu.com/share/link?shareid=2902188921&uk=923776187

GDataXML和TFHpple配置是一样的（配置方式参考 http://blog.csdn.net/ryantang03/article/details/7868246）

主要封装代码

html封装

#import <Foundation/Foundation.h>
#import "TFHpple.h"

@interface JSHpple : NSObject
+(id)ShareHpple;
-(NSArray *)HtmlWithData:(NSData *)data XPath:(NSString *)path;
@end

#import "JSHpple.h"

@implementation JSHpple

+(id)ShareHpple{
    static dispatch_once_t onceToken;
    static JSHpple *hpple=nil;
    dispatch_once(&onceToken, ^{
        hpple=[[JSHpple alloc] init];
    });
    return hpple;
}


-(NSArray *)HtmlWithData:(NSData *)data XPath:(NSString *)path{
    TFHpple *happen=[[TFHpple alloc] initWithHTMLData:data];
    NSArray *htmlContent=[happen searchWithXPathQuery:path];
    NSMutableArray *result=[NSMutableArray arrayWithCapacity:0];
    if (htmlContent.count<=0) {
        NSLog(@"没有解析到对应的数据");
        return nil;
    }
    for (TFHppleElement *ele in htmlContent) {
        NSString *content=[self SearchElement:ele];
        if (!content) {
            content=@"Null";
        }
        [result addObject:content];
    }
    
    return result;
    
}

-(NSString *)SearchElement:(TFHppleElement *)element{
      NSArray *childs=[element children];
    if (childs.count==1) {
        if ([[childs lastObject] isTextNode]) {//没有子节点
            return [element text];
        }
        else{//有子节点
            TFHppleElement *childElement=[childs lastObject];
            NSString *content=[self SearchElement:childElement];
            if (content) {
                return content;
            }
        }
    }
    return nil;
}


@end

xml  -->GDataxml的用法 （通用）

#import <Foundation/Foundation.h>
#import "GDataXMLNode.h"

@interface JSDataXml : NSObject

+(NSArray *)ParseXmlWithPath:(NSData *)data XPath:(NSString *)path attributes:(NSArray *)attributeArrarys;
@end


#import "JSDataXml.h"

@implementation JSDataXml



+(NSArray *)ParseXmlWithPath:(NSData *)data XPath:(NSString *)path attributes:(NSArray *)attributeArrarys{
    
    NSError *error=nil;
    //开始解析
    GDataXMLDocument *doc=[[GDataXMLDocument alloc] initWithData:data options:0 error:&error];
    if (error) {
        NSLog(@"xml解析失败-->%@",[error localizedDescription]);
        return nil;
    }
    //得到根元素
    GDataXMLElement *rootElement=[doc rootElement];
    //利用xpath找元素
    
    NSArray *Elements=[rootElement nodesForXPath:path error:&error];
    if (error) {
        NSLog(@"xpath有误-->%@",[error localizedDescription]);
        return nil;
    }
    if (Elements.count<=0) {
        NSLog(@"没有匹配到数据");
        return Elements;
    }
    

    NSMutableArray *result=[NSMutableArray array];
    //遍历匹配到的每个元素
    for (int i=0; i<Elements.count; i++) {
        GDataXMLElement *element=Elements[i];
        if (attributeArrarys.count>0) {//如果节点有元素
            NSMutableDictionary *dic=[NSMutableDictionary dictionaryWithCapacity:0];
            for (int i=0; i<attributeArrarys.count; i++) {
                NSString *key=attributeArrarys[i];
                NSString *value=[[element attributeForName:key] stringValue];
                if (!value) {
                    value=@"NULL";
                }
                [dic setObject:value forKey:key];
               
            }
             [result addObject:dic];
        }
        else{//如果节点没有元素，默认就返回属性值
            NSString *str= [element  stringValue];
            [result addObject:str];
        }

    }
    
    return result;
}

@end

xml 第二种封装（一个子节点没有属性）推荐使用

只适合这种xml数据格式

<?xml version="1.0" encoding="utf-8"?>  
<Users>  
    <User id="001">
        <name>Ryan</name>  
        <age>24</age>  
    </User>  
    <User id="002">  
        <name>Tang</name>  
        <age>23</age>  
    </User>  
</Users>

三种使用方式

#import "JSDataXml.h"
#import "JSHpple.h"
@interface ViewController (){
    //配置GDDataXML和TFHpple是相同的。
    //配置信息 http://blog.csdn.net/ryantang03/article/details/7868246
