推荐答案您的VB.NET代码就是这样. Your VB.NET Code will be something like this. Dim first, last As String first = "<p>" last = "</p>" Dim RE As New Regex(first + _ "(?<MYDATA>.*?(?=" + last + "))", _ RegexOptions.IgnoreCase Or RegexOptions.Singleline) Dim m As Match = RE.Match(yourData) '' got the result Dim output As String output = m.Groups("MYDATA").Value
使用正则表达式查找P标签并提取文本 Use a Regular Expression to find the P tags and extract the text
