VBA .innertext using getelements*, cannot locate areas in html code

问题


I am trying to create a macro to get the innertext from an internal webpage. I am not sure on how to properly locate the where the text is and would appreciate some direction and possibly some explanation on the approach.

I have tried numerous variations of using the getelementsby/tagname/classname to no avail. im not sure i understand the logic behind locating the areas after using the inspection function.

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

Here's the general logic of how to access the cells of an HTML table:

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

The code above will print Job # in the immediate window. This is the inner text of the first cell of the first row (which is the header of the first column). You can get the rest of the values accordingly.

Things to remember:

  1. doc.getElementsByClassName("table") is a collection of elements whose class name is "table"
  2. Same applies to .getElementsByTagName etc.
  3. The first item in the collection has an index of 0
  4. You can loop through all the elements in a collection using a For-Each
  5. This .getelementClassName is wrong
  6. This doc.getElementsByClassName("table")(0).getElementsByTagName("td")(0).innerText is correct
  7. You can access an item in the collection either like that doc.getElementsByClassName("Something").Item(0) or like that doc.getElementsByClassName("Something")(0)

The error:

The method is

getElementsByClassName 

or

getElementsByTagName

These return collections which you then index into e.g.

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

Making those changes should handle your initial error.


Targeting specific row and column:

You can use nth-of-type if automating with IE i.e. tr:nth-of-type(rowNumberHere) , td:nth-of-type(columnNumberHere).

I think you are after the second row first column so I would use css selectors

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

Modern browsers are optimized for css selectors so this should be an efficient method.


Entire table:

An easy way to copy an entire table is to use the clipboard

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
