我正在尝试将XHTML文档加载到XDocument中,但我得到了"引用未声明的实体"的例外情况.我需要解决像®和的实体».
我相信我的文件是正确形成的,这是头部:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
当我这样做XDocument.Load(<StringReader>)时,我会抛出这些异常.
我在WP7应用程序和C#3.5应用程序中运行完全相同的代码.在WP7应用程序将引发NotSupportedException在调用XDocument.Parse(),而C#3.5应用程序解析没有问题的XML.以下是使用的代码:
WebClient client = new WebClient();
client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(DownloadThreadsComplete);
client.DownloadStringAsync(new Uri("http://us.battle.net/sc2/en/forum/40568/", UriKind.Absolute));
...
private static void DownloadThreadsComplete(object sender, DownloadStringCompletedEventArgs e)
{
var doc = XDocument.Parse(e.Result);
}
知道为什么会这样吗？奇怪的是,当一个魔兽世界论坛工作得很好时(http://us.battle.net/wow/en/forum/984270/)尝试解析SC2论坛时失败了.
编辑:
异常消息是"NotSupportedException".这是完整的堆栈跟踪:
