标签: nsxmldocument

我将NSXMLElement在我的项目中使用,所以我试着

#import <Foundation/NSXMLDocument.h> 

但它给出了一个错误:"没有这样的文件或目录." 我怎么能包括这个？

我想从xml文件中获取一组元素,但是一旦元素涉及名称空间,它就会失败.

这是xml文件的一个片段:

我正在尝试创建一个应该包含solo标签的XML字符串(即.标签没有单独的结束标签)我能够创建正常的xml标签,如

<tagname attribute=attributevalue></tagname>

使用代码

NSXMLElement *childElement=[[NSXMLElement alloc] initWithName:childName];
childElement.stringValue=childValue;
[childElement addAttribute:[NSXMLNode attributeWithName:attributeName stringValue:attributeValue]];
[self.currentNode addChild:[childElement copy]];

但我需要这样的

<tagname attributename=attributevalue />

我正在尝试将文件读入NSXMLDocument.这是我的代码:

NSString *urlString = [@"~/Library/Preferences/Quark/QuarkXPress 8/OutputStyles.xml" stringByExpandingTildeInPath];
urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:urlString];

NSError *error = nil;

NSXMLDocument *doc = [[NSXMLDocument alloc] initWithContentsOfURL:url options:0 error:&error];
NSLog(@"%@", error);
NSLog(@"%@", doc);

但是,在控制台我得到:

2011-04-19 07:41:09.914 XMLTest[1409:a0f] Error Domain=NSURLErrorDomain Code=-1014 UserInfo=0x1001289d0 "zero byte resource"
2011-04-19 07:41:09.915 XMLTest[1409:a0f] (null)

关于什么可能是错的任何建议？我有那里的文件..我检查了100次...谢谢.

编辑:当我尝试使用[stringwithcontentofurl encoding error]方法在NSString中读取此内容时,我收到此错误:

Error Domain = NSCocoaErrorDomain Code = 262 UserInfo = 0x1006281c0"无法打开文件,因为不支持指定的URL类型." 基础错误=(错误域= NSURLErrorDomain代码= -1002 UserInfo = 0x1006280d0"不支持的URL"基础错误=(错误域= kCFErrorDomainCFNetwork代码= -1002 UserInfo = 0x100627d50"不支持的URL"))

我一直试图尝试使用NSXML解析器解析xml文件.因为我想使用NSXMLDocument类在其实例中存储数据.在以各种可能的方式搜索之后,我未能清楚地了解NSXMLDocument.我没有特别为此导入任何课程.我必须添加任何类或lib文件???
