我正在尝试从字符串中提取广告尺寸。广告尺寸均为标准尺寸。因此,虽然我更喜欢使用寻找模式的正则表达式,但IE 3数字后跟2或3个数字,硬编码也可以,因为我们知道尺寸是多少。以下是一些广告尺寸的示例:
300x250的
728x90的
320x50的
我能够找到一些我修改过的VBScript几乎可以工作,但由于我搜索的字符串不一致,所以在某些情况下它会拉得太多。例如:
您会看到它在每个实例中都无法正确匹配。
我找到的VB代码实际上是匹配除广告尺寸之外的所有内容。我对VBScript的了解不够充分,只需查看广告尺寸并将其拉出即可。因此,它会查找所有其他文本并将其删除。
代码如下。有没有办法修复正则表达式,以便它只返回广告尺寸?
Function getAdSize(Myrange As Range) As String
Dim regEx As New RegExp
Dim strPattern As String
Dim strInput As String
Dim strReplace As String
Dim strOutput As String
strPattern = "([^300x250|728x90])"
If strPattern <> "" Then
strInput = Myrange.Value
strReplace = ""
With regEx
.Global = True
.MultiLine = True
.IgnoreCase = True
.Pattern = strPattern
End With
If regEx.Test(strInput) Then
getAdSize = regEx.Replace(strInput, strReplace)
Else
getAdSize = "Not matched"
End If
End If
End Function
注意,数据并不总是由一个人提前完成,有时它是一个闪光或空间之前和之后的空间。

我已设法提供约95%的必需答案 - 以下RegEx将删除DDDxDD
大小,并将返回其余部分。
Option Explicit
Public Function regExSampler(s As String) As String
Dim regEx As Object
Dim inputMatches As Object
Dim regExString As String
Set regEx = CreateObject("VBScript.RegExp")
With regEx
.Pattern = "(([0-9]+)x([0-9]+))"
.IgnoreCase = True
.Global = True
Set inputMatches = .Execute(s)
If regEx.test(s) Then
regExSampler = .Replace(s, vbNullString)
Else
regExSampler = s
End If
End With
End Function
Public Sub TestMe()
Debug.Print regExSampler("uni3uios3_300x250_ASDF.html")
Debug.Print regExSampler("uni3uios3_34300x25_ASDF.html")
Debug.Print regExSampler("uni3uios3_8x4_ASDF.html")
End Sub
E.g。你会得到:
uni3uios3__ASDF.html
uni3uios3__ASDF.html
uni3uios3__ASDF.html
从这里,您可以继续尝试找到一种方法来反转显示。
修改强> 要从95%变为100%,I have asked a question here并且事实证明条件块应该更改为以下内容:
If regEx.test(s) Then
regExSampler = InputMatches(0)
Else
regExSampler = s
End If

编辑:由于它实际上没有下划线,我们无法使用Split
。然而,我们可以迭代字符串并提取&#34; #x#&#34;手动。我已更新代码以反映这一点并验证它是否成功。
Public Function ExtractAdSize(ByVal arg_Text As String) As String
Dim i As Long
Dim Temp As String
Dim Ad As String
If arg_Text Like "*#x#*" Then
For i = 1 To Len(arg_Text) + 1
Temp = Mid(arg_Text & " ", i, 1)
If IsNumeric(Temp) Then
Ad = Ad & Temp
Else
If Temp = "x" Then
Ad = Ad & Temp
Else
If Ad Like "*#x#*" Then
ExtractAdSize = Ad
Exit Function
Else
Ad = vbNullString
End If
End If
End If
Next i
End If
End Function
使用Select Case布尔逻辑而不是嵌套的If语句的相同函数的替代版本:
Public Function ExtractAdSize(ByVal arg_Text As String) As String
Dim i As Long
Dim Temp As String
Dim Ad As String
If arg_Text Like "*#x#*" Then
For i = 1 To Len(arg_Text) + 1
Temp = Mid(arg_Text & " ", i, 1)
Select Case Abs(IsNumeric(Temp)) + Abs((Temp = "x")) * 2 + Abs((Ad Like "*#x#*")) * 4
Case 0: Ad = vbNullString 'Temp is not a number, not an "x", and Ad is not valid
Case 1, 2, 5: Ad = Ad & Temp 'Temp is a number or an "x"
Case 4, 6: ExtractAdSize = Ad 'Temp is not a number, Ad is valid
Exit Function
End Select
Next i
End If
End Function

如果此公式总是3个字符,然后是x,并且它总是在下划线之间,则可以使用此公式 - 相应地进行调整。
=iferror(mid(A1,search("_???x*_",A1)+1,search("_",A1,search("_???x*_",A1)+1)-(search("_???x*_",A1)+1)),"No match")
