我正在解析一些XML数据，其中一个元素包含多个URLs，这些JPG由逗号分隔，指向URL个文件。我如何将每个NSScanner与字符串分开并将其分配给变量以便我可以拉出单个图片？我在想URLs会起作用，因为它扫描字符串寻找某些字符，但我并不完全确定。我还读到正则表达式也是可能的。关于我应该从哪里开始的想法？还有其他人需要将XML与字符串分开吗？此外，这是一个<vehicle>

从你的例子来看，假设你做了所有其余的解析，你得到了：
NSString *allURLs = @"http://image1.jpg,http://image2.jpg,http://image3.jpg";
您可以在数组中获取所有URL（对于循环很有用），如下所示：
NSArray *arrayOfImagesURLs = [allURLs componentsSeparatedByString:@","];
