This question is for manipulating NSString in xcode.
我有一个XML文本字符串,我从网上看到这样的
I have a XML text string that I get from the web that looks like this
<current temperature="73" day="Mon" humidity="59" windspeed="10"></current>
如何从此字符串中获取单个值并将它们放入我的NSString变量中?
How can I get individual values from this string and put them in my NSString variables?
例如
NSString *tempStr = ??
NSString *dayStr = ??
NSString *windspeedStr = ??
推荐答案
首先,按照描述在项目中下载并包含RaptureXML在 RaptureXML项目网站上。
First, download and include RaptureXML within your project as described on the RaptureXML project site.
用于解析单个给定行,使用以下代码段 - 您的输入传递为 inXmlString
;
For parsing the single given line, use the following snippet - your input is passed as inXmlString
;
//transform string into an XML DOM
RXMLElement *rootNode = [RXMLElement elementFromXMLString:inXmlString
withEncoding:NSUTF8StringEncoding];
if (rootNode == nil || ![rootNode isValid])
{
//do something, we failed!
}
else
{
NSString *temperature = [rootNode attribute:@"temperature"];
NSString *day = [rootNode attribute:@"day"];
NSString *windspeed = [rootNode attribute:@"windspeed"];
}
