搜索并替换不仅可以用空格分隔的整个单词 [英] Search and replace whole words which can be separated not only by a space

问题描述

我正在寻找一种搜索和替换整个单词的方法。整个单词不仅可以用空格分隔，还可以用.、；：/？等等

我想做这样的事情

replace([address], ***--list of separators, like .,;:/?--*** & [replacewhat] & ***--list of separators, like .,;:/?--*** ," " & [replacewith] & " ")

我不知道如何传递分隔符列表，而不是为每个分隔符组合运行一次替换函数(加上我要替换的300个单词，查询的数量将达到惊人的数量)。

推荐答案

您可以使用要替换的单词前后带有标记(表示单词边界)的模式，使用正则表达式进行替换。

Public Function RegExpReplaceWord(ByVal strSource As String, _
    ByVal strFind As String, _
    ByVal strReplace As String) As String
' Purpose   : replace [strFind] with [strReplace] in [strSource]
' Comment   : [strFind] can be plain text or a regexp pattern;
'             all occurences of [strFind] are replaced
    ' early binding requires reference to Microsoft VBScript
    ' Regular Expressions:
    'Dim re As RegExp
    'Set re = New RegExp
    ' with late binding, no reference needed:
    Dim re As Object
    Set re = CreateObject("VBScript.RegExp")

    re.Global = True
    're.IgnoreCase = True ' <-- case insensitve
    re.pattern = "" & strFind & ""
    RegExpReplaceWord = re.Replace(strSource, strReplace)
    Set re = Nothing
End Function

如前所述，搜索区分大小写。如果希望不区分大小写，请启用此行：

re.IgnoreCase = True

在"即时"窗口中.

? RegExpReplaceWord("one too three", "too", "two")
one two three
? RegExpReplaceWord("one tool three", "too", "two")
one tool three
? RegExpReplaceWord("one too() three", "too", "two")
one two() three
? RegExpReplaceWord("one too three", "to", "two")
one too three
? RegExpReplaceWord("one too three", "t..", "two")
one two three

..。和您的分隔符范围.

? RegExpReplaceWord("one.too.three", "too", "two")
one.two.three
? RegExpReplaceWord("one,too,three", "too", "two")
one,two,three
? RegExpReplaceWord("one;too;three", "too", "two")
one;two;three
? RegExpReplaceWord("one:too:three", "too", "two")
one:two:three
? RegExpReplaceWord("one/too/three", "too", "two")
one/two/three
? RegExpReplaceWord("one?too?three", "too", "two")
one?two?three
? RegExpReplaceWord("one--too--three", "too", "two")
one--two--three
? RegExpReplaceWord("one***too***three", "too", "two")
one***two***three
