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
