XML解析（android及ios的2种方法）

最近要做一个ios的项目，正努力熟悉ios的语法及工具。近期可能文章更多关于某一知识点android和ios的实现和对比。

也能更好的掌握这门语言，及更深了解android。

本文大纲：

1.android的sax解析。

2.ios的sax解析。

3.android的pull解析。

4.ios的tbxml解析。

本文没有什么好讲的只是分享demo。

首先用到的xml文件

person.xml

<?xml version="1.0" encoding="UTF-8"?>
<persons>
	<person id = "23">
		<name>NEwii</name>
		<age>21</age>
	</person>
	<person id = "20">
		<name>WiiWill</name>
		<age>25</age>
	</person>
</persons>

1.android sax

Person类

public class Person {

	public String id;
	public String name;
	public String age;
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getAge() {
		return age;
	}
	public void setAge(String age) {
		this.age = age;
	}
	
}

解析回调类

import java.util.ArrayList;
import java.util.List;

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

import android.util.Log;

public class SAXForHandler extends DefaultHandler {

	private String tag;
	private List<Person> persons;
	@Override
	public void startDocument() throws SAXException {
		// TODO Auto-generated method stub
		super.startDocument();
		persons=new ArrayList<Person>();
	}

	@Override
	public void endDocument() throws SAXException {
		// TODO Auto-generated method stub
		super.endDocument();
		Person person;
		for(int i=0;i<persons.size();i++)
        {
        	person=persons.get(i);
        	Log.v("id",person.getId());
        	Log.v("name",person.getName());
        	Log.v("age",person.getAge());
        }
	}

	@Override
	public void startElement(String uri,String localName,String qName,Attributes attributes) throws SAXException {
		// TODO Auto-generated method stub
		super.startElement(uri,localName,qName,attributes);
		tag=localName;
		if(localName.equals("person"))
		{
			Person person=new Person();
			person.setId(attributes.getValue(0));
			persons.add(person);
		}
	}

	@Override
	public void endElement(String uri,String qName)
			throws SAXException {
		// TODO Auto-generated method stub
        
	}

	@Override
	public void characters(char[] ch,int start,int length)
			throws SAXException {
		// TODO Auto-generated method stub
		String data=new String(ch,start,length);
		
		if(!data.trim().equals(""))
		{
			Person person=persons.get(persons.size()-1);
			if(tag.equals("name"))
				person.setName(data);
			if(tag.equals("age"))
				person.setAge(data);
		}
		super.characters(ch,length);
	}

	public List<Person> getPersons() {
		return persons;
	}

	public void setPersons(List<Person> persons) {
		this.persons = persons;
	}
    
}

private void sax_xml() {
		// TODO Auto-generated method stub
		try {
			InputStream in = getClass().getResourceAsStream("person.xml");
			SAXForHandler handler = new SAXForHandler();
			SAXParserFactory factory = SAXParserFactory.newInstance();
			SAXParser saxParser = factory.newSAXParser();
			saxParser.parse(in,handler);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

2.ios xml

@implementation ViewController

@synthesize dictionary;

    [super viewDidLoad];
	// Do any additional setup after loading the view,typically from a nib.

    }

{
    
}
@end

3.pull解析 android

private void pull_xml() {
		// TODO Auto-generated method stub
		int event;
		List<Person> persons=null;
		try {
			XmlPullParser parser = Xml.newPullParser();
			InputStream is = getClass().getResourceAsStream("person.xml");
			parser.setInput(is,"utf-8");
			event=parser.getEventType();
			while(event!=XmlPullParser.END_DOCUMENT)
			{
				switch (event) {
				case XmlPullParser.START_DOCUMENT:
					persons=new ArrayList<Person>();
					break;

				case XmlPullParser.START_TAG:
					String tag=parser.getName();
					if(tag.equals("person"))
					{
						Person person=new Person();
						person.setId(parser.getAttributeValue(0));
						persons.add(person);
					}
					else if(!tag.equals(""))
					{
						
						if(tag.equals("name"))
						{
							Person person=persons.get(persons.size()-1);
							person.setName(parser.nextText());
						}
						else if(tag.equals("age"))
						{
							Person person=persons.get(persons.size()-1);
							person.setAge(parser.nextText());
						}
					}
					break;
				
				default:
					break;
				}
				event=parser.next();
			}
			Person person;
			for(int i=0;i<persons.size();i++)
	        {
	        	person=persons.get(i);
	        	Log.v("id",person.getId());
	        	Log.v("name",person.getName());
	        	Log.v("age",person.getAge());
	        }
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

4.tbxml解析

1.首先下载tbxml

2.把这2个文件夹放入你的工程

3.引入libz.dylib库千万不要引入到测试工程中

4.加入宏定义#defin_ARC_ENABLED

5 加入同文件

//  xml

    TBXML* tbxml = [[TBXML alloc] initWithXMLFile:@"Notes.xml" error:nil];
    
    TBXMLElement * root = tbxml.rootXMLElement;
    
	// if root element is valid
	if (root) {

        while ( noteElement != nil) {
            
            NSMutableDictionary *dict = [NSMutableDictionary new];
            
            TBXMLElement *CDateElement = [TBXML childElementNamed:@"CDate" parentElement:noteElement];
            if ( CDateElement != nil) {

            }

            if ( ContentElement != nil) {

                [dict setValue:UserID forKey:@"UserID"];
            }
            
            //获得ID属性
            NSString *_id = [TBXML valueOfAttributeNamed:@"id" forElement:noteElement error:nil];
            [dict setValue:_id forKey:@"id"];
            
            [_notes addObject:dict];
            
            
            noteElement = [TBXML nextSiblingNamed:@"Note" searchFromElement:noteElement];
            
		}
    }
    
    NSLog(@"解析完成...");
    
    [[NSNotificationCenter defaultCenter] postNotificationName:@"reloadViewNotification" object:self.notes userInfo:nil];
    self.notes = nil;
