如何捕获< tags>内的文字,但从结果中排除标签? [英] How to capture text inside <tags> , but by excluding the tags from result?
问题描述
在Visual Basic中我试图在标签之间获取文本,但也会捕获TAGS。
我希望在消息中看到结果仅为捕获的文本盒子。
但结果是以捕获文本的形式出现前后两个标签。
我的代码出了什么问题?
我尝试了什么:
Public Sub Button1_Click(发送者为对象,e为EventArgs)处理Button1.Click
Dim pattern As String =< tag>(。+?)< \ / tag>
Dim text As String =Other Text< tag>捕获文本其他文本
昏暗捕获匹配= Regex.Match(文本,模式)
MsgBox(capture.Value)
结束Sub
正则表达式捕获您告诉它的文本 - 在您的情况下包括标签。
您可以使用非捕获前缀和后缀:
(?< =< tag>)(。+?)(?=< \ / tag>)但是如果您正在尝试处理HTML,我建议使用正确的解析器: Html敏捷包| HAP [ ^ ]是一个好的开始。
我找到了解决方案
我必须使用Groups(1)才能获取标签内的文本..这是溶液..
In Visual Basic I am trying to get text between tags but TAGS are also captured.
I want to see the result as ONLY "Captured Text" in message box.
But result is coming as "Captured Text" with both tags before and after .
What is wrong in my code?
What I have tried:
Public Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim pattern As String = "<tag>(.+?)<\/tag>"
Dim text As String = "Other Text <tag>Captured Text Other Text"
Dim capture As Match = Regex.Match(text, pattern)
MsgBox(capture.Value)
End Sub
A regex captures the text you told it to - which in your case includes teh tags.
You can use an non-capturing prefix and suffix:
(?<=<tag>)(.+?)(?=<\/tag>)But if you are trying to process HTML, I'd recommend a proper parser instead: Html Agility Pack | HAP[^] is a good start.
I found the solution
I must use Groups(1) for getting only text inside tags ..This is the solution..
