题
我正试图从网络词典中获取某些单词的发音。例如，在下面的代码中，我想从http://collinsdictionary.com获得good发音
（此处使用HTTP Agility Pack ）
static void test()
{
String url = "http://www.collinsdictionary.com/dictionary/english/good";
WebClient client = new WebClient();
client.Encoding = System.Text.Encoding.UTF8;
String html = client.DownloadString(url);
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
HtmlAgilityPack.HtmlNode node = doc.DocumentNode.SelectSingleNode("//*[@id=\"good_1\"]/div[1]/h2/span/text()[1]");
if (node == null)
{
Console.WriteLine("XPath not found.");
}
else
{
Console.WriteLine(node.WriteTo());
}
}
我在期待
static void test()
{
String url = "http://www.collinsdictionary.com/dictionary/english/good";
WebClient client = new WebClient();
client.Encoding = System.Text.Encoding.UTF8;
String html = client.DownloadString(url);
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
HtmlAgilityPack.HtmlNode node = doc.DocumentNode.SelectSingleNode("//*[@id=\"good_1\"]/div[1]/h2/span/text()[1]");
if (node == null)
{
Console.WriteLine("XPath not found.");
}
else
{
Console.WriteLine(node.WriteTo());
}
}
但我最多能得到的是
static void test()
{
String url = "http://www.collinsdictionary.com/dictionary/english/good";
WebClient client = new WebClient();
client.Encoding = System.Text.Encoding.UTF8;
String html = client.DownloadString(url);
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
HtmlAgilityPack.HtmlNode node = doc.DocumentNode.SelectSingleNode("//*[@id=\"good_1\"]/div[1]/h2/span/text()[1]");
if (node == null)
{
Console.WriteLine("XPath not found.");
}
else
{
Console.WriteLine(node.WriteTo());
}
}
如何做到对了？
一般承认的答案
问题不在于解析文本，而是控制台输出存在问题。如果从命令行应用程序执行此操作，则可以将控制台的输出编码设置为unicode：
Console.OutputEncoding = System.Text.Encoding.Unicode;
您还需要确保控制台中的字体是具有unicode支持的字体。有关详细信息，请参阅此答案 。

如果您知道页面编码（例如System.Text.Encoding.UTF8）;
string html = DownloadSmallFiles_String(url, System.Text.Encoding.UTF8, 20000);
或使用自动编码检测（取决于服务器响应）
string html = DownloadSmallFiles_String(url, System.Text.Encoding.UTF8, 20000);
最后加载html
string html = DownloadSmallFiles_String(url, System.Text.Encoding.UTF8, 20000);
试试下面的代码
string html = DownloadSmallFiles_String(url, System.Text.Encoding.UTF8, 20000);
