VBA .innertext 使用 getelements*，无法定位 html 代码中的区域

Question

我正在尝试创建一个宏来从内部网页获取内部文本。我不确定如何正确定位文本所在的位置，希望能得到一些指导，并可能对方法进行一些解释。

我尝试了多种使用 getelementsby/tagname/classname 的变体，但都无济于事。我不确定我是否理解使用检查功能后定位区域背后的逻辑。

Var = ie.document.getelementClassName("sections").getElementsByTagName("table").Item(0).innerText

'also tried
Var = ie.document.getelementClassName("sections").getElementsByTagName("table").Item(1).getElementsByTagName("tr").Item(2).getElementsByTagName("td").Item(0).innerText

Var = ie.document.getelementTagName("section").getElementsByTagName("table").Item(1).getElementsByTagName("tr").Item(2).getElementsByTagName("td").Item(0).innerText


ActiveCell.Offset(0, 1).Value = Var

错误 438

Answer 1

下面是如何访问 HTML table 的单元格的一般逻辑：

Sub test()
Dim sht As Worksheet
Dim doc As New HTMLDocument
Dim targetTable As HTMLTable
Set sht = ThisWorkbook.Worksheets("Sheet1")
doc.body.innerHTML = sht.Range("M1") 'I just stored the html code in cell M1 as a string for the sake of demonstration

Set targetTable = doc.getElementsByClassName("table")(0) 'Get the first element from a collection of elements whose class name is "table"
Debug.Print targetTable.Rows(0).Cells(0).innerText 'Get the first row from the collection of rows that belong to the table and the first cell from the collection of cells that belong to this row.
End Sub

上面的代码将在立即 window 中打印 Job #。这是第一行第一个单元格的内部文本（即第一列的 header）。您可以相应地获取其余值。

要记住的事情：

doc.getElementsByClassName("table") 是 collection 个元素，其 class 名称为 "table"
同样适用于.getElementsByTagName等
collection 中的第一项的索引为 0
您可以使用 For-Each
这个.getelementClassName是错误的
这个doc.getElementsByClassName("table")(0).getElementsByTagName("td")(0).innerText是正确的
您可以像 doc.getElementsByClassName("Something").Item(0) 或 doc.getElementsByClassName("Something")(0)

Answer 2

错误：

方法是

getElementsByClassName

或

getElementsByTagName

这些 return 集合，然后您将其编入索引，例如

ie.document.getElementsByClassName("className")(0)  'first element

进行这些更改应该可以解决您的初始错误。

针对特定的行和列：

如果使用 IE 进行自动化，则可以使用 nth-of-type，即 tr:nth-of-type(rowNumberHere)，td:nth-of-type(columnNumberHere)。

我认为你在第二行第一列之后，所以我会使用 css 选择器

ie.document.querySelector(".table tr:nth-of-type(2) td:nth-of-type(1)").innerText

现代浏览器针对 css 选择器进行了优化，因此这应该是一种有效的方法。

整个table:

复制整个 table 的一种简单方法是使用剪贴板

Option Explicit
Public Sub GetInfo()
    Dim ie As New InternetExplorer, url As String, ws As Worksheet
    Dim t As Date, clipboard As Object, hTable As Object
    url = "url"
    Const MAX_WAIT_SEC As Long = 10

    Set ws = ThisWorkbook.Worksheets("Sheet1")
    Set clipboard = GetObject("New:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")

    With ie
        .Visible = True
        .Navigate2 url

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

        With .document

            t = Timer
            Do
                On Error Resume Next
                Set hTable = .querySelector(".table")
                On Error GoTo 0
                If Timer - t > MAX_WAIT_SEC Then Exit Do
            Loop While hTable Is Nothing
        End With

        If hTable Is Nothing Then Exit Sub
            clipboard.SetText hTable.outerHTML
            clipboard.PutInClipboard
            ws.Range("A1").PasteSpecial
        .Quit
    End With
End Sub

循环行和列 table:

如果要循环 table 的行和列并写出，请参阅。
