Question

所以，我有这个HTML代码：

<div class="keyboard">
  <p>
    Hello world!
  </p>
</div>

我想获得文字＆＃34; Hello world！＆＃34;。我已尝试使用下面的正则表达式代码，但它没有用。

Dim findtext2 As String = "(?<=<div class=""keyboard"">)(.*?)(?=</div>)"
Dim myregex2 As String = TextBox1.Text 'HTML code above
Dim doregex2 As MatchCollection = Regex.Matches(myregex2, findtext2)
Dim matches2 As String = ""
For Each match2 As Match In doregex2
    matches2 = matches2 + match2.ToString + Environment.NewLine
Next
MsgBox(matches2)

正如评论中提到的那样，不要使用ReGex来解析HTML代码而是使用LINQ to XML

Dim html As XElement =
    <html>
        <body>
            <div class = "keyboard">
                <p>Hello word!</p>
            </div>
        </body>
    </html>

Dim values As String = 
    html.Descendants("div").
         Where(Function(div) div.Attribute("class").Value.Equals("keyboard")).
         Select(Function(div) div.Element("p").Value)

For Each value As String in values
    Console.WriteLine(value);
End For
