IOS 解析XML文档 使用TBXML

使用TBXML解析XML文档时，采用的是DOM模式。

TBXML框架需要去下载

下载地址 https://github.com/71squared/TBXML

技术网站 http://www.tbxml.co.uk/TBXML/TBXML_Free.html

需要将TBXML-HEADERS 和 TBXML-Code文件夹添加到工程中。还要注意一下它所依赖的库

Foundation.framework

UIKit.framework

CoreGraphics.framework

libz.dylib

还需要做一些设置，在Objective-C版本中，需要在工程预编译头文件PrefixHeader.pch中添加如下代码：

#import <Foundation/Foundation.h>

#define ARC_ENABLED

工程没有.pch文件需新建一个，去设置里配置一下。

Notes.xml文档

<?xml version="1.0" encoding="UTF-8"?>
<Notes>
    <Note id="1">
        <Name>赵一</Name>
        <Sex>男</Sex>
        <Age>40</Age>
    </Note>
    <Note id="2">
        <Name>钱二</Name>
        <Sex>女</Sex>
        <Age>30</Age>
    </Note>
    <Note id="3">
        <Name>张三</Name>
        <Sex>男</Sex>
        <Age>25</Age>
    </Note>
    <Note id="4">
        <Name>李四</Name>
        <Sex>女</Sex>
        <Age>20</Age>
    </Note>
</Notes>

Objective-C代码

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

@interface NotesTBXMLParser : NSObject

@property (strong, nonatomic) NSMutableArray *notes;

- (void)start:(NSString*)fileName;

@end

#import "NotesTBXMLParser.h"

@implementation NotesTBXMLParser

@synthesize notes = _notes;

- (void)start:(NSString*)fileName
{
    _notes = [NSMutableArray new];
    TBXML *tbxml = [[TBXML alloc] initWithXMLFile:[fileName stringByAppendingString:@".xml"] error:nil];
    TBXMLElement *root = tbxml.rootXMLElement;
    
    if (root) {
        TBXMLElement *noteElement = [TBXML childElementNamed:@"Note" parentElement:root];
        while (noteElement != nil) {
            NSMutableDictionary *dict = [NSMutableDictionary new];
            
            TBXMLElement *NameElement = [TBXML childElementNamed:@"Name" parentElement:noteElement];
            if (NameElement != nil) {
                NSString *Name = [TBXML textForElement:NameElement];
                [dict setValue:Name forKey:@"Name"];
            }
            
            TBXMLElement *SexElement = [TBXML childElementNamed:@"Sex" parentElement:noteElement];
            if (SexElement != nil) {
                NSString *Sex = [TBXML textForElement:SexElement];
                [dict setValue:Sex forKey:@"Sex"];
            }
            
            TBXMLElement *AgeElement = [TBXML childElementNamed:@"Age" parentElement:noteElement];
            if (AgeElement != nil) {
                NSString *Age = [TBXML textForElement:AgeElement];
                [dict setValue:Age forKey:@"Age"];
            }
            
            NSString *_id = [TBXML valueOfAttributeNamed:@"id" forElement:noteElement error:nil];
            [dict setValue:_id forKey:@"id"];
            
            [_notes addObject:dict];
            
            noteElement = [TBXML nextSiblingNamed:@"Note" searchFromElement:noteElement];
        }
    }
    
    [[NSNotificationCenter defaultCenter] postNotificationName:@"reloadViewNotification" object:self.notes userInfo:nil];
    self.notes = nil;
}
@end

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reloadView:) name:@"reloadViewNotification" object:nil];
    
    NotesTBXMLParser *tbParser = [NotesTBXMLParser new];
    [tbParser start:@"Notes"];
    
}

- (void)reloadView:(NSNotification*)notification
{
    NSMutableArray *resList = [notification object];
    NSLog(@"%@", resList);
}

Swift代码

在Swift版本中，我们需要在每个TBXML头文件中添加以下内容

#import <Foundation/Foundation.h>

#define ARC_ENABLED

在桥接头文件My-Bridging-Header.h中引入头文件TBXML.h。

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        NSNotificationCenter.defaultCenter().addObserver(self, selector: "reloadView:", name: "reloadViewNotification", object: nil)
        
        var parser = NotesTBXMLParser()
        parser.start("Notes")
    }

    func reloadView(notification : NSNotification)
    {
        var resList = notification.object as! NSMutableArray
        NSLog("%@", resList)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

import Foundation

class NotesTBXMLParser: NSObject {
    private var notes : NSMutableArray!
    
    func start(name : String)
    {
        self.notes = NSMutableArray()
        
        var tbxml = TBXML(XMLFile: name.stringByAppendingString(".xml"), error: nil)
        var root = tbxml.rootXMLElement
        
        if root != nil {
            var noteElement = TBXML.childElementNamed("Note", parentElement: root)
            
            while noteElement != nil {
                var dict = NSMutableDictionary()
                
                var NameElement = TBXML.childElementNamed("Name", parentElement: noteElement)
                if NameElement != nil {
                    var Name = TBXML.textForElement(NameElement)
                    dict.setValue(Name, forKey: "Name")
                }
                
                var SexElement = TBXML.childElementNamed("Sex", parentElement: noteElement)
                if SexElement != nil {
                    var Sex = TBXML.textForElement(SexElement)
                    dict.setValue(Sex, forKey: "Sex")
                }
                
                var AgeElement = TBXML.childElementNamed("Age", parentElement: noteElement)
                if AgeElement != nil {
                    var Age = TBXML.textForElement(AgeElement)
                    dict.setValue(Age, forKey: "Age")
                }
                
                var id = TBXML.valueOfAttributeNamed("id", forElement: noteElement)
                dict.setValue(id, forKey: "id")
                
                self.notes.addObject(dict)
                
                noteElement = TBXML.nextSiblingNamed("Note", searchFromElement: noteElement)
            }
        }
        
        NSNotificationCenter.defaultCenter().postNotificationName("reloadViewNotification", object: self.notes)
        self.notes = nil
    }
}
