iPhone如何使用NSXMLParser获取CDATA属性？

发布于 2024-11-10 06:08:42 字数 980 浏览 0 评论 0原文

我想从在线 XML 进行解析，其中 XML 如下所示：

<menu maincategory="![CDATA[Erhverv]]" subcategory="![CDATA[Erhvervsregister]]" category="![CDATA[Akupunktur]]"/>

在函数解析器 didStartElement 中，我使用如下所示：

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
    if ([elementName isEqualToString:@"menu"]) {
        NSString *maincategory = [attributeDict objectForKey:@"maincategory"];
    }
}

使用 %@ 输出如下所示：

attributeDict:{
    category = "![CDATA[Advokater]]";
    maincategory = "![CDATA[Erhverv]]";
    subcategory = "![CDATA[Erhvervsregister]]";
}


2011-05-27 19:20:42.663 XML[62494:840b] maincategory using %s: `ãâå
2011-05-27 19:20:42.663 XML[62494:840b] maincategory using %@: ![CDATA[Erhverv]]

但我需要不带 ![CDATA] 标签的输出

任何人都可以帮忙我该如何解决这个问题？提前致谢

I want to parse from an online XML where the XML is like below:

<menu maincategory="![CDATA[Erhverv]]" subcategory="![CDATA[Erhvervsregister]]" category="![CDATA[Akupunktur]]"/>

In the function parser didStartElement i used like below:

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
    if ([elementName isEqualToString:@"menu"]) {
        NSString *maincategory = [attributeDict objectForKey:@"maincategory"];
    }
}

The output is like below using %@:

attributeDict:{
    category = "![CDATA[Advokater]]";
    maincategory = "![CDATA[Erhverv]]";
    subcategory = "![CDATA[Erhvervsregister]]";
}


2011-05-27 19:20:42.663 XML[62494:840b] maincategory using %s: `ãâå
2011-05-27 19:20:42.663 XML[62494:840b] maincategory using %@: ![CDATA[Erhverv]]

But i need the output without the ![CDATA] tag

Can anyone please help me that how can i solve that?
Thanks in advance

我将使用 NSRegularExpression 对象对 attributeDict 进行后期处理。对于字典中的每个字符串，将其复制到 NSMutableString（在下面的代码中名为 theString）并运行以下代码：

NSError *theError = nil;
NSRegularExpression *theExpression = [NSRegularExpression regularExpressionWithPattern:@"!\\[CDATA\\[(.*)\\]\\]" options:(NSRegularExpressionOptions)nil error:&theError];
NSUInteger count = [theExpression replaceMatchesInString:theString options:(NSRegularExpressionOptions)nil range:NSMakeRange(0, [theString length]) withTemplate:@"$1"];

I would post process the attributeDict with an NSRegularExpression object. For each string in the dictionary, copy it into an NSMutableString (named theString in my code below) and run this code:

NSError *theError = nil;
NSRegularExpression *theExpression = [NSRegularExpression regularExpressionWithPattern:@"!\\[CDATA\\[(.*)\\]\\]" options:(NSRegularExpressionOptions)nil error:&theError];
NSUInteger count = [theExpression replaceMatchesInString:theString options:(NSRegularExpressionOptions)nil range:NSMakeRange(0, [theString length]) withTemplate:@"$1"];
