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:];
if (htmlContent.count<=) {
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==) {
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: 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<=) {
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=; i<Elements.count; i++) {
GDataXMLElement *element=Elements[i];
if (attributeArrarys.count>) {//如果节点有元素
NSMutableDictionary *dic=[NSMutableDictionary dictionaryWithCapacity:];
for (int i=; 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"?>

#import "JSDataXml.h"
#import "JSHpple.h"
