将HTML表转换为Excel

下面的代码在https://rasmusrhl.github.io/stuff处获取HTML表格，并将其转换为Excel格式。

问题在于：

括号中的数字转换为负数
数字被舍入或截断

解决方案

谢谢大家的贡献。各种各样的anwers帮助我理解，为了我的目的，解决方法是最好的解决方案：因为我自己生成HTML表，所以我可以控制每个单元格的CSS。存在指示Excel如何使用的CSS代码解释单元格内容：http://cosicimiento.blogspot.dk/2008/11/styling-excel-cells-with-mso-number.html，也在此解释问题：Format HTML table cell so that Excel formats as text?

在我的情况下，CSS应该是文本，即mso-number-format:\"\\@\"。它集成在下面的R代码中：

library(htmlTable)
library(nycflights13)
library(dplyr)

nycflights13::planes %>% 
    slice(1:10) %>% mutate( seats = seats*1.0001,
                            s1    = c("1-5", "5-10", "1/2", "1/10", "2-3", "1", "1.0", "01", "01.00", "asfdkjlæ" ),
                            s2    = c("(10)", "(12)", "(234)", "(00)", "(01)", "(098)", "(01)", "(01.)", "(001.0)", "()" )) -> df 


rle_man <- rle(df$manufacturer)

css_matrix <- matrix( data = "mso-number-format:\"\\@\"", nrow = nrow(df), ncol = ncol(df))
css_matrix[,1] <- "padding-left: 0.4cm;mso-number-format:\"\\@\""
css_matrix[,2:10] <- "padding-left: 1cm;mso-number-format:\"\\@\""
css_matrix[,5] <- "padding-left: 2cm;mso-number-format:\"\\@\""


htmlTable( x = df,  
           rgroup   = rle_man$values, n.rgroup = rle_man$lengths, 
           rnames   = FALSE, align = c("l", "r" ), 
           cgroup   =  rbind(  c("", "Some text goes here. It is long and does not break", "Other text goes here", NA),
                               c( "", "Machine type<br>(make)", "Specification of machine", "Other variables")),
           n.cgroup = rbind(   c(1,8,2, NA),
                               c(1, 3, 5, 2)), 
           css.cell = css_matrix )            -> html_out

temp_file <- tempfile( pattern = "table", fileext = ".html" )
readr::write_file( x = html_out, path = temp_file)
utils::browseURL( temp_file)

可以将HTML文件拖放到Excel中，并将所有单元格解释为文本。请注意，只将 html-file 拖放到Excel中才能正常工作，无法在浏览器中打开表并将其复制粘贴到Excel中。

这种方法唯一缺少的是水平线，但我可以忍受。

以下是VBA，与拖放效果相同：

对于客户端解决方案

因此，在第一个代码块之后运行此代码，它会重写最后两列。

Sub Test2()
    '* tools references ->
    '*   Microsoft HTML Object Library


    Dim oHtml4 As MSHTML.IHTMLDocument4
    Set oHtml4 = New MSHTML.HTMLDocument

    Dim oHtml As MSHTML.HTMLDocument
    Set oHtml = Nothing

    '* IHTMLDocument4.createDocumentFromUrl
    '* MSDN - IHTMLDocument4 createDocumentFromUrl method - https://msdn.microsoft.com/en-us/library/aa752523(v=vs.85).aspx
    Set oHtml = oHtml4.createDocumentFromUrl("https://rasmusrhl.github.io/stuff/", "")
    While oHtml.readyState <> "complete"
        DoEvents  '* do not comment this out it is required to break into the code if in infinite loop
    Wend
    Debug.Assert oHtml.readyState = "complete"


    Dim oTRs As MSHTML.IHTMLDOMChildrenCollection
    Set oTRs = oHtml.querySelectorAll("TR")
    Debug.Assert oTRs.Length = 17

    Dim lRowNum As Long
    For lRowNum = 3 To oTRs.Length - 1

        Dim oTRLoop As MSHTML.HTMLTableRow
        Set oTRLoop = oTRs.Item(lRowNum)
        If oTRLoop.ChildNodes.Length > 1 Then

            Debug.Assert oTRLoop.ChildNodes.Length = 14

            Dim oSecondToLastColumn As MSHTML.HTMLTableCell
            Set oSecondToLastColumn = oTRLoop.ChildNodes.Item(12)

            ActiveSheet.Cells(lRowNum + 2, 13).Value2 = "'" & oSecondToLastColumn.innerText


            Dim oLastColumn As MSHTML.HTMLTableCell
            Set oLastColumn = oTRLoop.ChildNodes.Item(13)

            ActiveSheet.Cells(lRowNum + 2, 14).Value2 = "'" & oLastColumn.innerText

        End If
        'Stop

    Next lRowNum

    ActiveSheet.Columns("M:M").EntireColumn.AutoFit
    ActiveSheet.Columns("N:N").EntireColumn.AutoFit


End Sub

对于服务器端解决方案

既然我们知道您控制源脚本并且它在R中，那么可以更改R脚本以使用mso-number-format设置最终列的样式：＆＃39; \ @＆＃39; 。下面是一个实现此目的的示例R脚本，一个构建与数据尺寸相同的CSS矩阵，并将CSS矩阵作为参数传递给htmlTable。我没有篡改过您的R源代码，而是在这里给出一个简单的插图供您解读。

A=matrix(c("(2)","(4)","(3)","(1)","(5)","(7)"),nrow=2,ncol=3,byrow=TRUE)
css_matrix <- matrix(data="",nrow=2,ncol=3)
css_matrix[,3] <- "mso-number-format:\"\\@\""
htmlTable(x=A,css.cell=css_matrix)

在Excel中打开我得到了这个

Robin Mackenzie添加了

您可能会在服务器端解决方案中提到OP只需要添加css_matrix [，10：11]＆lt; - ＆＃34; mso-number-format：\＆＃34; \ @ \＆＃34;＆＃34;他们的现有的R代码（在最后一个css_matrix ...行之后）它会针对特定问题实施解决方案

谢谢罗宾

Answer 2

要从该页面获取表格数据（保持格式不变），您可以尝试如下：

 Sub Fetch_Data()
    Dim http As New XMLHTTP60, html As New HTMLDocument
    Dim posts As Object, post As Object, elem As Object
    Dim row As Long, col As Long

    With http
        .Open "GET", "https://rasmusrhl.github.io/stuff/", False
        .send
        html.body.innerHTML = .responseText
    End With

    Set posts = html.getElementsByClassName("gmisc_table")(0)

    For Each post In posts.Rows
        For Each elem In post.Cells
            col = col + 1: Cells(row + 1, col).NumberFormat = "@": Cells(row + 1, col) = elem.innerText
        Next elem
        col = 0
        row = row + 1
    Next post
End Sub

参考添加到库：

1. Microsoft HTML Object Library
2. Microsoft XML, v6.0  'or whatever version you have

这是解析时该部分的样子。

这适用于临时文件。

它的作用：本地下载数据。然后，替换＆＃34;（＆＃34;用＆＃34; \＆＃34;。然后，导入数据。将数据格式化为文本（以确保我们可以无错误地将其更改）。然后，更改文本。使用Range.Replace无法完成此操作，因为这将重新格式化单元格内容。

Answer 4

您可以尝试一下，看看您是否获得了所需的输出......

Sub GetWebData()
Dim IE As Object
Dim doc As Object
Dim TRs As Object
Dim TR As Object
Dim Cell As Object
Dim r As Long, c As Long

Application.ScreenUpdating = False

Set IE = CreateObject("InternetExplorer.Application")
IE.Visible = False
IE.navigate "https://rasmusrhl.github.io/stuff/"
Do While IE.Busy Or IE.readyState <> 4
    DoEvents
Loop
Set doc = IE.document

Set TRs = doc.getElementsByTagName("tr")
Cells.Clear

For Each TR In TRs
    r = r + 1
    For Each Cell In TR.Children
        c = c + 1
        Cells(r, c).NumberFormat = "@"
        Cells(r, c) = Cell.innerText
    Next Cell
    c = 0
Next TR
IE.Quit
Columns.AutoFit
Application.ScreenUpdating = True
End Sub

解决方案2：

要使其正常工作，您需要通过转到工具（在VBA编辑器上）添加以下两个引用 - ＆gt;引用然后找到下面提到的两个引用并选中它们的复选框，然后单击OK。

1）Microsoft XML，v6.0（找到可用的最大版本）

2）Microsoft HTML对象库

Sub GetWebData2()
Dim XMLpage As New MSXML2.XMLHTTP60
Dim doc As New MSHTML.HTMLDocument
Dim TRs As IHTMLElementCollection
Dim TR As IHTMLElement
Dim Cell As IHTMLElement
Dim r As Long, c As Long

Application.ScreenUpdating = False

Set XMLpage = CreateObject("MSXML2.XMLHTTP")

XMLpage.Open "GET", "https://rasmusrhl.github.io/stuff/", False
XMLpage.send
doc.body.innerhtml = XMLpage.responsetext
Set TRs = doc.getElementsByTagName("tr")
Set TRs = doc.getElementsByTagName("tr")
Cells.Clear

For Each TR In TRs
    r = r + 1
    For Each Cell In TR.Children
        c = c + 1
        Cells(r, c).NumberFormat = "@"
        Cells(r, c) = Cell.innerText
    Next Cell
    c = 0
Next TR
Columns.AutoFit
Application.ScreenUpdating = True
End Sub

Answer 5

<style type=text/css>
    td {mso-number-format: '\@';}
</style>
<table ...

将单元格（<td> s）的上述全局样式定义放在您使用R 或生成的输出上，在客户端重写文档，如下所示。

Sub importhtml()
    '*********** HTML document rewrite process ***************
    Const TableUrl = "https://rasmusrhl.github.io/stuff"

    End With

    'download HTML document
    With CreateObject("MSXML2.ServerXMLHTTP")
        .Open "GET", TableUrl, False
        .Send
        If .Status <> 200 Then Err.Raise 3, "importhtml", "200 expected"

Answer 7

处理HTML然后将其复制并粘贴到Excel中

以下是我使用的步骤：

CreateObject("MSXML2.XMLHTTP")：获取网址的responseText
CreateObject("HTMLFile")：从responseText
用黑色替换灰色以使边框变暗
使用@对列s1和s2进行前缀以保留格式
将HTML复制到Windows剪贴板
- 注意：HTML需要包含在HTML和Body标签中才能正确粘贴
设置目标工作表
将HTML粘贴到工作表
将@符号替换为'
- 注意：这会通过将数据存储为文本来保留格式
完成格式化工作表

Sub LoadTable()
    Const URL = "https://rasmusrhl.github.io/stuff/"
    Dim x As Long
    Dim doc As Object, tbl As Object, rw As Object
    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", URL, False

            Set doc = CreateObject("HTMLFile")
            doc.body.innerHTML = .responseText
            doc.body.innerHTML = Replace(doc.body.innerHTML, "grey", "black")
            Set tbl = doc.getElementsByTagName("TABLE")(0)

            For x = 0 To tbl.Rows.Length - 1

                    rw.Cells(13).innerText = "@" & rw.Cells(13).innerText
                End If
            Next

            With CreateObject("new:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")

Answer 8

根据Microsoft MSDN Library: WebFormatting Property的文档，您可以尝试对代码进行以下更改：

 .WebFormatting = xlWebFormattingNone

这可能允许在没有任何数字格式的情况下复制数据 - 然后您可以为这些单元格设置自己的数字格式（使用MSDN: Excel VBA NumberFormat property）

使用网址https://rasmusrhl.github.io/stuff，幸运的是Excel可以直接打开它并保存为.xlsx（在繁琐的过程之前怎么没有人尝试这个）。如果直接打开失败，这里的所有其他方法都是很好的选择！

Option Explicit

Sub OpenWebFile()
    Const URL As String = "https://rasmusrhl.github.io/stuff"
    Dim oWB As Workbook
    On Error Resume Next
    Set oWB = Workbooks.Open(Filename:=URL, ReadOnly:=True)
    If oWB Is Nothing Then
        MsgBox "Cannot open the url " & URL, vbExclamation + vbOKOnly, "ERR " & Err.Number & ":" & Err.Description
        Err.Clear
    Else
        ' Change to your desired path and filename
        oWB.SaveAs Filename:="C:\Test\stuff.xlsx", FileFormat:=xlOpenXMLWorkbook
        Set oWB = Nothing
    End If
End Sub
