Arrays VBA-如何使用不同大小的多个分隔符构建数组?
如果我有多个分隔符,其中一些分隔符是单个字符,而另一些分隔符是多个字符,如何构建数组Arrays VBA-如何使用不同大小的多个分隔符构建数组?,arrays,vba,split,Arrays,Vba,Split,如果我有多个分隔符,其中一些分隔符是单个字符,而另一些分隔符是多个字符,如何构建数组 Sub Example() Dim exString As String Dim myString() As String exString = "A,B C;D > E" myString() = Split(exString, "," & " " & ";" & " > ") End Sub 我希望数组中的结果是: myString(
Sub Example()
Dim exString As String
Dim myString() As String
exString = "A,B C;D > E"
myString() = Split(exString, "," & " " & ";" & " > ")
End Sub
我希望数组中的结果是:
myString(0) is A
myString(1) is B
myString(2) is C
myString(3) is D
myString(4) is E
但是以这种方式使用
Split()。我知道我可以使用Replace()
将每个分隔符替换为一个公共分隔符,但是我有很多不同的分隔符和多个字符分隔符的变体。我不希望使用Replace()
。我能做什么?在这种情况下,我发现以下功能非常适合我的需要:

' are next to each other.
'MultiCharDelimiter is a string of specific multi-character delimiters.

Dim re As New RegExp
re.Pattern = "(,| |;|>)+"

然后将任何匹配的模式替换为,

如果您只需要对结果进行迭代并对其进行处理,那么这就足够了。如果您特别需要一个包含结果的数组:

你的职能是正确的。使用ParamArray,您可以轻松更改分隔符的数量和位置
代码
试验
结果
注意:使用多字符分隔符时,分隔符的处理顺序很重要。请注意,A1被正确拆分,但不正确,因为空格分隔符出现在函数的正确轨道之前。使用ParamArray,您可以轻松更改分隔符的数量和位置

- 临时分隔符是集合特定的字符
- 包含或删除空数组项的选项
- 更改引用的函数(ByRef vs ByVal)
- 传递分隔符数组与列出单个分隔符
这将产生以下输出:
示例2
在本例中,我们将removeblankeitems
设置为False
Sub Example2()
Dim myString As String, c, n
n = 0
myString = "The,Quickupside-downBrownjelloFox_Jumped[Over] ThegiantLazyjelloDog"
For Each c In MultiSplitX(myString, True, ",", "-", "upside-down", "jello", " ", "[", "]", "giant", "_")
Debug.Print "(" & n & ") = " & c
n = n + 1
Next c
Debug.Print myString
End Sub
这将产生以下输出:
示例3
在本例中,我们没有在函数中列出分隔符,而是将它们键入字符串,并在函数中插入数组:
Sub Example3()
Dim myString As String, c, n
Dim myDelimiters As String
n = 0
myString = "The,Quickupside-downBrownjelloFox_Jumped[Over] ThegiantLazyjelloDog"
myDelimiters = ",|-|upside-down|jello| |[|]|giant|_"
For Each c In MultiSplitX(myString, True, Split(myDelimiters, "|"))
Debug.Print "(" & n & ") = " & c
n = n + 1
Next c
Debug.Print myString
End Sub
这与单独列出的结果相同:
删除空白项的原因是可取的
在某些情况下,您不希望数组中有空格。这方面的一个例子是,如果您使用数组作为一组搜索词,这些词在电子表格的某个范围内循环。另一个例子是,如果您正在根据数组中的值操作文本字符串
有时还需要在数组中保留空格。正如Thomas所描述的,如果您在CSV文件上使用此选项,则需要将空格保持为列。或者您使用它来分解,例如HTML编码,并希望保留行格式。以下是Thomas Inzina编写的代码的一个内置版本
