这篇文章给大家分享的是有关IOS如何解析XML文件 的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
这里使用NSXMLParser来解析，这个是apple自带的xml解析库
在Xcode中加入一个xml文件:
计算
安全
数据库
网络和加速
企业服务
<?xml version="1.0" encoding="ISO-8859-1"?>
<root>
<Shop shoplocation="beijing">
<id>001</id>
<name>John</name>
<url>Reminder</url>
<info>Don't forget the meeting!</info>
</Shop>
<Shop shoplocation="dongcheng">
<id>002</id>
<name>Jack</name>
<url>cc</url>
<info>how are you!</info>
</Shop>
<Shop shoplocation="haidian">
<id>003</id>
<name>Tom</name>
<url>bb</url>
<info>I am fine!</info>
</Shop>
</root>先读出来
NSString* path = [[NSBundle mainBundle] pathForResource:@"shop" ofType:@"xml"];
NSData *data = [[NSData alloc] initWithContentsOfFile:path options:(NSDataReadingMappedIfSafe) error:nil];
NSXMLParser *parser=[[NSXMLParser alloc] initWithData:tmpdata];
<span style="white-space:pre"> </span>[parser setDelegate:self];
[parser parse];
[parser release];
[self parseShopListFromResponse:data];然后进行解析:
#pragma mark NSXMLParser delegate methods
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
attributes: (NSDictionary *)attributeDict {
self.currentTag = elementName;
if ([elementName isEqualToString:@"root"]) {
self.tmpList = [[NSMutableArray alloc] init];
}else if ([elementName isEqualToString:@"Shop"]) {
self.tmpShop = [[ShopData alloc] init];
NSArray* array = [attributeDict allKeys];
NSString* key = [array lastObject];
NSString*s = [attributeDict objectForKey:key];
self.tmpShop.info = s;
}
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
if (self.currentString == nil) {
self.currentString = [[NSMutableString alloc] initWithString:@""];
}
if ([self.currentTag isEqualToString:@"name"] ||
[self.currentTag isEqualToString:@"id"] ||
[self.currentTag isEqualToString:@"url"] ||
[self.currentTag isEqualToString:@"info"]) {
[self.currentString appendString:string];
}
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if ([elementName isEqualToString:@"Shop"]) {
[self.tmpList addObject:self.tmpShop];
[self.tmpShop release];
} if ([elementName isEqualToString:@"name"]) {
self.tmpShop.name = [self.currentString copy];
[self.currentString setString:@""];
}else if ([elementName isEqualToString:@"id"]) {
self.tmpShop._id = [self.currentString copy];
[self.currentString setString:@""];
}else if ([elementName isEqualToString:@"url"]) {
self.tmpShop.url = [self.currentString copy];
[self.currentString setString:@""];
}else if ([elementName isEqualToString:@"info"]) {
// self.tmpShop.info = [self.currentString copy];
// [self.currentString setString:@""];
}
}
- (void)parserDidStartDocument:(NSXMLParser *)parser {
NSLog(@"开始解析xml文件");
}
- (void)parserDidEndDocument:(NSXMLParser *)parser {
[self.tableView reloadData];
NSLog(@"解析xml文件完成");
}Shopdata的结构是:
@property (nonatomic,retain) NSString *name;
@property (nonatomic,retain) NSString *url;
@property (nonatomic,retain) NSString *_id;
@property (nonatomic,retain) NSString *info;
@property (nonatomic, retain) UIImage *appIcon;感谢各位的阅读！关于“IOS如何解析XML文件 ”这篇文章就分享到这里了，希望以上内容可以对大家有一定的帮助，让大家可以学到更多知识，如果觉得文章不错，可以把它分享出去让更多的人看到吧！
