CSS选择器方法：

元素的确切CSS选择器是：

#infoBox > div.col-xs-12.thumbnail.thumbnail-more > div:nth-child(3) > h3

您可以简化为：

甚至

一旦获得HTML文档，就可以使用以下任何选择器访问：

.querySelector("#infoBox > div.col-xs-12.thumbnail.thumbnail-more > div:nth-child(3) > h3").InnerText
.querySelector("#infoBox *> div:nth-child(3) > h3").InnerText
.querySelector(".valueText").InnerText

以下是使用Internet Explorer和上面显示的CSS选择器之一提取当前价格（10美元）的示例：

代码：

Option Explicit

Public Sub GetInfo()
    Dim IE As Object
    Dim html As Object

    With CreateObject("InternetExplorer.Application")
        .Visible = True
        .navigate "https://stashpedia.com/funko/pop-vinyl/thundercats/tygra-exclusive-573"

        While .Busy Or .readyState < 4: DoEvents: Wend

        Set html = .document

        With html
           Debug.Print .querySelector("#infoBox *> div:nth-child(3) > h3").innerText
        End With

        Stop
        'Quit '<== Remember to quit application
    End With
End Sub

CSS选择器here的信息。

XPath方法：

如果您想使用上面显示的方法不支持的XPath，您可以使用Selenium basic，您的脚本可能如下：

Option Explicit
Public Sub GetInfoSel()
    Dim d As WebDriver
    Set d = New ChromeDriver
    Const URL = "https://stashpedia.com/funko/pop-vinyl/thundercats/tygra-exclusive-573"

    With d
        .Start "Chrome"
        .Get URL
       Debug.Print .FindElementByXPath("//*[@id=""infoBox""]/div[1]/div[3]/h3").Text
        'Quit
    End With
End Sub

注意：下载并安装后，您需要转到工具＆gt; VBE中的引用并添加对Selenium Type库的引用
