如何在使用HtmlAgilityPack.HtmlDocument.LoadHtml时设置编码 [英] How to set encoding when using HtmlAgilityPack.HtmlDocument.LoadHtml

问题描述

我已经拥有HTML页面的来源所以我正在使用

I already have the source of HTML page so i am using

string html_page_source="some page source crawled before";
HtmlDocument hdMyDoc = new HtmlDocument();
hdMyDoc.LoadHtml(html_page_source);

但是我看到没有解码的字符，例如

However i see not decoded characters such as

  
içerisinde 
göründüğünden çok
.
.

那么如何在htmldocument设置自动解码？



我如何设置默认编码来解决这个问题？



以下方法是一个好习惯吗？

So how can i set auto decode at htmldocument ?

How can i set default encoding to solve this problem ?

And would this below method a good practice ?

hdMyDoc.LoadHtml(HttpUtility.HtmlDecode(html_page_source));

Html Agility Pack配备了一个名为 HtmlEntity的实用程序类。它有一个带有以下签名的静态方法：

The Html Agility Pack is equiped with a utility class called HtmlEntity. It has a static method with the following signature:

/// <summary>
/// Replace known entities by characters.
/// </summary>
/// <param name="text">The source text.</param>
/// <returns>The result text.</returns>
public static string DeEntitize(string text)

它支持众所周知的实体（如& nbsp; ）和编码字符，例如& ;＃039; 以及。

It supports well-known entities (like  ) and encoded characters such as ' as well.

从文档中提取字符串后，使用此方法进行转换HTML编码的实体返回文本字符。



在尝试加载文档之前，不要对源进行HTML解码;你将完全改变标记的含义。

Once you've extracted the string from the document, use this method to convert the HTML-encoded entities back to text characters.

Don't HTML-decode the source before trying to load the document; you'll completely change the meaning of the markup.
