推荐答案
如在其他答案中之前所述，您xml中的数据位于CDATA块中-这意味着当您获取标记的内容时，XML解析器将无法为您摆脱按:"位-就其而言，全都是文本.
As said before in other answers, the data in your xml is inside a CDATA block - this means that when you get the contents of the tag, the XML parser won't be able to get rid of the 'By:' bit for you - as far as it's concerned, it's all just text.
但是，如果要在UIWebView(而不是UILabel等)中以HTML的形式将其显示在内部，则可以在字符串的开头添加样式表，以使"By:"隐藏.像
However,if you're going to display it inside as HTML inside a UIWebView (instead of a UILabel etc), you can add a style sheet to the start of the string that makes the 'By:' hidden. Something like
NSString *cssString = @"<style type='text/css'>span.by { display:none; }</style>"
NSString *html = [NSString stringWithFormat:@"<html><head>%@</head><body>%@</body></html>", cssString, descriptionString];
[webView loadHTMLString:html baseURL:nil];
其中descriptionString是xml中<description>标记的内容.
where descriptionString is the contents of the <description> tag in your xml.
但是这种方法有点繁琐，我会非常努力地从您的服务器中获取一些更干净的xml！
However this approach is a little heavy handed, I would try very hard to get some cleaner xml from your server!
至于实际解析xml，请尝试 NSXMLParser 对象.
As for actually parsing the xml, try the NSXMLParser object.
