iphone - HTML 解析因重音字母而失败(例如 : é)

Question

我正在使用这个库:http://benreeves.co.uk/objective-c-hmtl-parser/为我正在制作的一个小 iPhone 应用程序解析 HTML。到目前为止，我已经让代码工作了，但是当出现重音时它会失败(到目前为止只有经验丰富的 é)。这是我正在使用的代码:

NSError * error = nil;
HTMLParser * parser = [[HTMLParser alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://intranet.westminster.org.uk/almanack/food.asp?nextweek=TRUE"] error:&error];

if (error) {
    NSLog(@"Error: %@", error);
    return nil;
}
HTMLNode * bodyNode = [parser body]; //Find the body tag
NSArray *individualMeals = [bodyNode findChildTags:@"font"];
for (HTMLNode *node in individualMeals) {
    if ([[node getAttributeNamed:@"color"] isEqual:@"green"]) {
        NSLog(@"%@",[node rawContents]);
    }
}

但它不会解析所有文本。在 URL 中找到重音后，它似乎放弃了。这是它在运行时产生的结果:

它放弃了带有炒土 bean 的部分，并且不从该部分或后面的任何部分返回任何结果。

我认为这可能是由于网站没有对 és 进行编码。当我查看源代码时，我看到的是 é 而不是 & eacute; (没有空格，否则 SO 格式化它......)本网站建议: http://www.w3.org/MarkUp/html3/latin1.html

谢谢你的时间。如果您知道从该网站获取午餐食物的更好方法，我也很想听听。

我有类似的问题。问题是 libxml2 只能解析 UTF8 编码的文档。所以你需要先将html页面转换为UTF8。
