PreviousSibling不使用querySelector

Question

我正在尝试从位于C：\ Sample.html的本地html文件中提取两个部分 我从类似的另一个线程中使用了@QHarr代码

Sub Test()
Dim html As HTMLDocument, post As Object, i As Long

Set html = GetHTMLFileContent("C:\Sample.html")
Set post = html.querySelectorAll("span.course-player__chapter-item__completion")

For i = 0 To post.Length - 1
    ActiveSheet.Cells(i + 1, 1) = Trim(post.item(i).innerText)
    ActiveSheet.Cells(i + 1, 2) = post.item(i).PreviousSibling.innerText
Next i
End Sub

Function GetHTMLFileContent(ByVal filePath As String) As HTMLDocument
Dim fso As Object, hFile As Object, hString As String, html As HTMLDocument

Set html = New HTMLDocument
Set fso = CreateObject("Scripting.FileSystemObject")
Set hFile = fso.OpenTextFile(filePath)

Do Until hFile.AtEndOfStream
    hString = hFile.ReadAll()
Loop

html.body.innerHTML = hString
Set GetHTMLFileContent = html
End Function

代码可以正常工作，并可以获取post.item(i).innerText部分中元素的内部文本。 但是，当尝试获取上一个兄弟姐妹的内文时，它不会返回任何内容

这是html的快照

Answer 1

我使用了CSS选择器，该选择器使用h2[class='course-player__chapter-item__title _chapter-item__title_d57kmg']返回所有值，然后将输出分为两列

Sub Test()
Dim x, html As HTMLDocument, post As Object, s As String, i As Long

Set html = GetHTMLFileContent("C:\Sample.html")
Set post = html.querySelectorAll("h2[class='course-player__chapter-item__title _chapter-item__title_d57kmg']")

For i = 0 To post.Length - 1
    x = Split(Trim(post.item(i).innerText), " ")
    s = Join(Array(x(UBound(x)), x(UBound(x) - 1), x(UBound(x) - 2)), " ")
    ReDim Preserve x(0 To UBound(x) - 3)

    ActiveSheet.Cells(i + 1, 1) = Trim(Join(x, " "))
    ActiveSheet.Cells(i + 1, 2) = Trim(s)
Next i
End Sub
