vb.net - 拆分文本以获得特定值

Question

如何拆分此 xml 节点以仅获取数字值？

<span>All Potatoes: 4</span>

像这样的东西:

Dim code as string = "<span>All Potatoes: 4</span>"
Dim splitrsult as string
Splitresult = splitresult("<span>All Potatoes:" & "</span>")
Msgbox(splitresult)

我是这种语言的新手，如果有帮助，将不胜感激。谢谢!

将 XML 作为 XML 处理! (不是简单的字符串)

使用这个导入语句

Imports System.Xml.Linq

然后解析您的字符串以获取 Xml 元素并获取其值

Dim code As String = "<span>All Potatoes: 4</span>"
Dim node = XElement.Parse(code)
Dim result As String = node.Value ' ==> "All Potatoes: 4"
