如何使用asp.net从字符串中删除HTML标记（粗体，强，字体名称等） [英] How to remove HTML tags from string using asp.net (Bold,strong,font names etc etc)

问题描述

我使用CKEditor输入详细信息（详细信息包含html元素）。之后，细节将绑定到网格中。在这里我想在工具提示中显示没有html标签的细节。

  protected   void  grdStepMain_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
 < span class =code-keyword> int  i =  0 ; 
  if （e.Row.RowType == DataControlRowType.DataRow）
 {
  foreach （TableCell cell  in  e.Row.Cells）
 {
 i ++; 
  string  description = cell.Text; 
  if （cell.Text.Length >   8 &&（i ==  2 ））
 cell.Text = cell.Text.Substring（ 0 ， 8 ）+   ....; 
  string  newdescription = Regex.Replace（description， @ < [^>] +> |& nbsp;，  ）修剪（）; 
 cell.ToolTip = newdescription; 
} 
 
} 
} 

但它不起作用请帮助我。示例：

  string  str = & lt; h1& gt;& lt; span style =& quot; font-family：courier  new ， courier ，monospace& quot;& gt;& lt; strong& gt; 457457& lt; / strong& gt; 544444444444457457457& lt; / span& gt;; 
 
    result   in   tooltip       457457544444444444457457457  

请帮我

In您的评论，您说HTML标签实际上是由HTML实体组成的。在这种情况下，从< 到> 匹配的正则表达式将不起作用;你需要一个匹配从& lt; 到& gt; ：
$ b $的正则表达式b

  string  newdescription = Regex.Replace（description， @ & lt;。+？& gt; |& nbsp;， ）修剪（）; 

I am using CKEditor to enter details (The details contains html elements). after that the details will be bind into a grid. In this I want to show the details without html tags in tooltip.

protected void grdStepMain_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        int i = 0;
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            foreach (TableCell cell in e.Row.Cells)
            {
                i++;
                string description = cell.Text;
                if (cell.Text.Length > 8 && (i == 2))
                    cell.Text = cell.Text.Substring(0, 8) + "....";
              string newdescription = Regex.Replace(description, @"<[^>]+>|&nbsp;", "").Trim();
              cell.ToolTip = newdescription;
            }

        }
    }

But its not working please help me. Example:

string str= " <h1><span style="font-family:courier new,courier,monospace"><strong>457457</strong> 544444444444457457457</span>";

The result in tooltip should be 457457544444444444457457457

Please hep me

In your comment, you said that the HTML tags are actually made up with HTML Entities. In that case, a regex that matches from < to > won't work; you need a regex that matches from < to >:

string newdescription = Regex.Replace(description, @"<.+?>| ", "").Trim();
