我找不到这些解析技术的比较.哪一个最常用？
问候.穆斯塔法
我正在尝试使用任何一个基于libxml的第三方XML解析器,但我不能,因为我认为我有某种类型的libxml2问题
我将其他链接器标志设置为-lxml2
和/ usr/include/libxml2的标题搜索路径
但是当我尝试编译时,我仍然会得到大量未定义的符号.以下错误是尝试编译TouchXML的结果.

<?xml version="1.0" encoding="utf-8"?>
<FundInfo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/webservices">
<FundsReleaseDate>2009-02-11T00:00:00</FundsReleaseDate>
<FundValue>7800</FundValue>
<FundShares>1000</FundShares>
</FundInfo>
我想获得7800,即FundValue.有人点我在正确的方向,我现在用的是TouchXml CXMLDocument和myParser的类型是CXMLDocument的,我曾尝试
NSArray *nodes = [myParser nodesForXPath:@"//FundInfo" error:&err];
基本上节点的评估结果为零
if ([nodes count] > 0 ) {
amount = [nodes objectAtIndex:1];
}
更新1:我已经使用XPath放弃解析,并用的NSURLRequest取代它,所以现在我有一个字符串在整个XML,但我的粗鲁介绍客观-C继续...我只是意识到如何撒娇我已经成为了.NET BCL,像Regex这样的东西很容易获得.
UPDATE2:我已经想通了如何使用RegexKitLite的正则表达式.
所以,现在的问题是,我该如何获得"7800"由内FundValue现在是一个大的字符串.我已确认我有它在我的NSString使用NSLog的写它.
我刚刚将TouchXML添加到我的项目中,它告诉我:
警告:阻塞:/**/Classes/Creation是版本控制下的阻止项
同样,Tidy也是如此:
警告:阻塞:/**/Classes/Tidy是版本控制下的阻止项
这只是一个警告,但它非常烦人; 我怎么能摆脱它？
如何使用touchXML解析此XML？我想将所有属性存储为字典中的键/值对.

欢迎任何指示,谢谢
TouchXML仍然可用吗？我找不到更新的下载源,要么很旧,要么找不到404 URL？
它不再可用吗？
我有一个具有以下结构的XML,我正在尝试从此创建我的模型对象.有人可以帮我找到一种方法,使用TouchXML,NSMutableArray和NSMutableDictionay从XML中获取这些对象.

我需要解析它<response>和它的孩子.
我正在努力学习objective-c(我对此非常新)并且我在内存管理方面存在问题......
我正在开发一款使用TouchXML的iPad应用程序.
我创建了扩展CXMLDocument的类,并通过读取一些内容并保存到属性中进行初始化.
这是我的代码(SimpleManifest.h):
@interface SimpleManifest : CXMLDocument {
CXMLNode *_defaultOrganization;
NSString *_title;
NSDictionary *dictionary;
}
@property (readonly) CXMLNode *defaultOrganization;
@property (readonly) NSString* title;
- (id) initWithPath:(NSString *)path options:(NSUInteger)options error:(NSError **)error;
@end
(SimpleManifest.m):
#import "SimpleManifest.h"
#import "CXMLNode_XPathExtensions.h"
@implementation SimpleManifest

{

NSURL *theURL = [[[NSURL alloc] initFileURLWithPath:path] autorelease];
self = [self initWithContentsOfURL:theURL options:options error:error];

NSData *data = [NSData dataWithContentsOfFile:path];
NSString *s = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease];
