[英]Excel VBA: How to remove substrings from a cell (with same beginning and ending symbol)?
[英]Excel VBA: How to remove substrings from a cell?
我有這樣的單元格值:
This is a <"string">string, It should be <"changed">changed to <"a"> a number.
在這部分中重復了一些單詞<" ">
。
我想使用Excel VBA將單元格值更改為:
This is a string, It should be changed to a number.
任何幫助將不勝感激。 謝謝。
繼續使用正則表達式的建議,這是一個例子:
Option Explicit
Sub RemoveByRegexWithLateBinding()
Dim strIn As String
Dim strOut As String
Dim objRegex As Object
'input
strIn = "This is a <""string"">string, It should be <""changed"">changed to <""a""> a number."
Debug.Print "Input:" & vbCr & strIn
'create and apply regex
Set objRegex = CreateObject("VBScript.RegExp")
objRegex.Pattern = "<""[^<>""]*"">"
objRegex.Global = True
strOut = objRegex.Replace(strIn, "")
'test output
Debug.Print "Output:" & vbCr & strOut
End Sub
生成此輸出:
Input:
This is a <"string">string, It should be <"changed">changed to <"a"> a number.
Output:
This is a string, It should be changed to a number.
正則表達式圖:
這可以解釋為找到一個字符串:
<"
開頭 <
, >
和"
字符之外的任何內容 ">
結尾 假設單元格A1中的文本,然后嘗試此代碼
Sub DelDoubleString()
Dim Text As String, Text2Replace As String, NewText As String
On Error Resume Next 'Optional, in case there's no double string to be deleted
Text = Cells(1, 1)
Do
Text2Replace = Mid$(Text, InStr(Text, "<"), InStr(Text, ">") - InStr(Text, "<") + 1)
NewText = Application.WorksheetFunction.Substitute(Text, Text2Replace, vbNullString)
Text = NewText
Loop Until InStr(NewText, "<") = 0
Cells(1, 1) = NewText
End Sub
選擇包含文本的單元格並運行此短宏:
Sub Kleanup()
Dim d As Range, s As String, rng As Range
Dim gather As Boolean, L As Long, DQ As String
Dim i As Long, s2 As String, CH As String
Set rng = Selection
DQ = Chr(34)
For Each r In rng
s = Replace(r.Text, "<" & DQ, Chr(1))
s = Replace(s, DQ & ">", Chr(2))
gather = True
L = Len(s)
s2 = ""
For i = 1 To L
CH = Mid(s, i, 1)
If CH = Chr(1) Then gather = False
If CH = Chr(2) Then gather = True
If gather And CH <> Chr(2) Then s2 = s2 & CH
Next i
r.Value = s2
Next r
End Sub
你可以使用替換功能
ActiveSheet.Cells(1, 1).Value = Replace(ActiveSheet.Cells(1, 1).Value, "String", "Number")
