如何在HTML中编码特殊字符但排除标签 [英] How to encode special characters in HTML but exclude tags

问题描述

我正在尝试将HTML页面转换为包含适当命名实体的页面，将引号，双引号转换为实体.我尝试了以下有效的代码，但对HTML标记进行了编码，我想不加赘述.任何想法如何做到这一点?

I'm trying to convert an HTML page into one containing proper named entities, converting quotes, double quotes to entities. I tried the following code which works but encodes the HTML tags, which I want to leave alone. Any ideas how to do this?

public static string HtmlEncode(string text)
{
    string result;
    using (StringWriter sw = new StringWriter())
    {
        var x = new HtmlTextWriter(sw);
        x.WriteEncodedText(text);
        result = sw.ToString();
    }
    return result;
}

推荐答案

如上面的MatthewG所述，答案已经发布到

As noted by MatthewG above, the answer had already been posted to html entity encode text only, not html tag - the solution is to use HTMLAgilityPack and pass the html text or node to the method entitize - this encodes only the page content and not the tags.

using HtmlAgilityPack;
html = HtmlEntity.Entitize(html);
