Question

内容

&nbsp;&nbsp;&nbsp;&nbsp;Hello World.

<a&nbsp;href="#"&nbsp;target=_blank>hello&nbsp;World</a>

如何替换html代码中的 并将其他 保留在文本中。

Answer 1

对我而言，最好的是：

Imports System.Web
HttpUtility.HtmlDecode(codeHtml)

Answer 2

您可以尝试搜索

(?<=<[^>]*)&nbsp;

并用一个空格替换它？

这会查找 内部标记（前面有<，可能还有>以外的其他字符）。

但是，这非常脆弱。例如，如果字符串/属性中包含< / >符号，则会失败。最好避免将 放在错误的位置。

Answer 3

youString.Replace("&nbsp;", " ");

Answer 4

string A = HttpContext.Current.Server.HtmlDecode(Text);

string A = Text.Replace("&nbsp"," ");

string A = Text.Replace("&amp;nbsp;", " ");

                           ↑ &amp;nbsp;

Answer 5

这会找到包含＆amp; nbsp：

的所有文本条

<[^>]+?&nbsp;[^<]+?>

Fropm在这里你可以做一个简单的字符串替换空格，因为Regex会在你的文本中给你匹配的lcoation。

Answer 6

只需将文字替换为以下文字后的字符串。

xyz.Text.Replace(" ", string.Empty);

//Funciona!!!!!!!!!!!!!!!

string a =UnHtml(text);

 private static readonly Regex _tags_ = new Regex(@"<[^>]+?>", RegexOptions.Multiline | RegexOptions.Compiled);

        //replace matches of these regexes with space
        html = _tags_.Replace(html, " ");
        html = _notOkCharacter_.Replace(html, " ");
