Question

我无法从https://next-episode.net/star-trek-picard抓取值。我希望从“ Previous__episode”标签ID中提取季节编号。该数字似乎介于2个标签之间，我似乎无法找到引用它的方法。香港专业教育学院以前一直拉所有previous_episode标签的内部文本，并使用正则表达式函数来隔离我想要给我以下内容的值

上一集

名称：碎块

日期：

2020年3月12日

季节：

1

集锦：8

摘要：情节摘要

（在excel中，它们之间没有任何一行。由于某些原因，问题框中的格式将它们全部放在一行上）

在今晚之前，数字1与“ Season：”位于同一行，从而允许我的正则表达式功能正常工作。或者可能是一个正则表达式，让我在“季节：”之后的下一行获得1。

我想这可能会帮助您获得希望获取的必填字段：

Sub FetchData()
    Const Url$ = "https://next-episode.net/star-trek-picard"
    Dim HTML As New HTMLDocument, post As Object
    Dim rxp As New RegExp, R&

    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", Url, False
        .send
        HTML.body.innerHTML = .responseText
    End With

    Set post = HTML.getElementById("previous_episode")

    With rxp
        .pattern = "(Name:(.*))"
        If .Execute(post.innerText).Count > 0 Then
            R = R + 1: Cells(R, 1) = .Execute(post.innerText)(0).SubMatches(0)
        End If

        .pattern = "(Season:\s*([0-9]*))"
        If .Execute(post.innerText).Count > 0 Then
            Cells(R, 2) = .Execute(post.innerText)(0).SubMatches(0)
        End If

        .pattern = "(Episode:([0-9]*))"
        If .Execute(post.innerText).Count > 0 Then
            Cells(R, 3) = .Execute(post.innerText)(0).SubMatches(0)
        End If
    End With
End Sub

        .pattern = "(Name:(.*))"
        If .Execute(post.innerText).Count > 0 Then
            R = R + 1: Cells(R, 1) = .Execute(post.innerText)(0).SubMatches(0)
        End If

        .pattern = "(Season:\s+([0-9]*))"
        If .Execute(post.innerText).Count > 0 Then
            CleanString = Application.WorksheetFunction.Clean(.Execute(post.innerText)(0).SubMatches(0))
            SeasonNumber = Split(CleanString, ":")
            Cells(R, 2) = SeasonNumber(1)
        End If

        .pattern = "(Episode:([0-9]*))"
        If .Execute(post.innerText).Count > 0 Then
            Cells(R, 3) = .Execute(post.innerText)(0).SubMatches(0)
        End If
    End With
End Sub

使用DOM更加方便快捷。您想要的节点是NextSiblings到与尼斯且快速的CSS选择器#previous_episode .subheadline匹配的项目。您将获得一个返回的nodeList，它们是左侧的元素，例如“名称”，“日期”等...只需使用NextSibling导航到右侧元素，例如“等着阿卡迪亚自我，第1部分”。

返回的nodeList从0开始，您可以索引以获取单个项目。请注意，您想要的第二项是textNode，因此必须使用NodeValue属性而不是innerText。

这在处理HTML解析方面更快，更正确。

Option Explicit
Public Sub GetPriorEpisodeInfp()
    Const URL = "https://next-episode.net/star-trek-picard"
    Dim html As New mshtml.HTMLDocument, previousEpisodeItems As Object

    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", URL, False
        .send
        html.body.innerHTML = .responseText
    End With

    Set previousEpisodeItems = html.querySelectorAll("#previous_episode  .subheadline")

    With ActiveSheet
        .Cells(1, 1) = previousEpisodeItems.item(0).NextSibling.innerText
        .Cells(1, 2) = previousEpisodeItems.item(2).NextSibling.NodeValue 'textNode
        .Cells(1, 3) = previousEpisodeItems.item(3).NextSibling.innerText
    End With
End Sub
