VBA/VBScript批量搜索多个Word或者Excel指定的包含文字

!本文可能 超过1年没有更新，今后内容也许不会被维护或者支持，部分内容可能具有时效性，涉及技术细节或者软件使用方面，本人不保证相应的兼容和可操作性。

假设我们有多个Word或者Excel文件，现在我们要从这些文件中搜索特定的关键字，比较笨的办法就是一个一个打开，然后“编辑 – 查找”，文件少还好办，如果文件比较多的话，那么打开这么多文件也累得我们够呛。

下面我讲解一个利用VBScript自动批量搜索特定文字的办法，首先还是上面的算法，只不过将人工一个一个打开换成计算机自动打开。实际上这里主要是枚举文件，然后在利用ActiveX控件调用Word.Application或者Excel.Application内部的查找方法来实现相关功能。

对于一份简单的Word文档，基本的查找VBA可以像下面这样实现：

Dim hasFound ' 定义是否找到
Selection.WholeStory
With Selection.Find
    .ClearFormatting
    .MatchWholeWord = False
    .MatchCase = False
    hasFound = .Execute("要查找的文字")
End With

转化为VBScript代码也很容易，多个创建Word.Application并打开Word文件的过程。

下面定义FileFinder接口，当然VBS没有接口的概念，我们只是象征式的说明下：

Interface FileFinder
    Function isTextExists(search, filename)
    End Function
End Interface

只需要实现一个方法接口，那就是isTextExists，判断要搜索的文本是否存在于指定的文件中。下面给出关于Word查找的VBS脚本代码实现：

Class DocumentsFinder
 
    Private vbaObject
    Private Application
 
    Private Sub Class_Initialize()
        Set vbaObject = WSH.CreateObject("Word.Application")
            vbaObject.Visible = False
    End Sub
 
    Private Sub Class_Terminate()
            vbaObject.Visible = True
            vbaObject.Quit
        Set vbaObject = Nothing
    End Sub
 
    Private Function SearchStringInSingleDocument(str, doc)
        Dim Selection
        Set Selection = vbaObject.Selection
            Selection.WholeStory
            With Selection.Find
                .ClearFormatting
                .MatchWholeWord = False
                .MatchCase = False
                SearchStringInSingleDocument =.Execute(str)
            End With
        Set Selection = Nothing
    End Function
 
    Public Function isTextExists(str, filename)
        On Error Resume Next
        Dim doc
        Set doc = vbaObject.Documents.Open(filename)
            isTextExists = SearchStringInSingleDocument(str, doc)
            doc.Close
        Set doc = Nothing
        If Err Then Err.Clear
    End Function
End Class

其中调用了Documents.Open打开一个Word文档，然后再通过SearchStringInSingleDocument方法来搜索指定文档的文字，这个方法就是刚才讲解的VBA宏的实现。

关于Excel的查找和Word稍有不同，大家知道一份Excel文件算是工作簿（WorkBook），工作簿里面有多个工作表（WorkSheet），比如Sheet1、Sheet2等，所以我们需要搜索当前工作簿下的所有工作表，然后通过调用Sheet.Cells.Find方式来检索文字是否存在，关于Excel的Find查找文字的方式可以参考微软的《Cells.Find 返回错误时找到不匹配》，基本VBA代码如下：

Dim hasFound ' 定义是否找到
Dim RangeObj
For Each Sheet In Workbooks.Worksheets
    Set RangeObj = Sheet.Cells.Find(str)
    hasFound = CBool(Not (RangeObj Is Nothing))
    Set RangeObj = Nothing
    If hasFound Then Exit For
Next

基于刚才叙述的FileFinder接口，相关代码实现如下：

            vbaObject.Visible = False
    End Sub
 
    Private Sub Class_Terminate()
            vbaObject.Visible = True
            vbaObject.Quit
        Set vbaObject = Nothing
    End Sub
 
    Private Function SearchStringInSingleSheet(str, sheet)
        ' See http://support.microsoft.com/kb/108892
        Dim RangeObj
        Set RangeObj = sheet.Cells.Find(str)
            SearchStringInSingleSheet = CBool(Not (RangeObj Is Nothing))
        Set RangeObj = Nothing
    End Function
 
    Public Function isTextExists(str, filename)
        On Error Resume Next
        isTextExists = False
        Dim Workbooks,Worksheets
        Set Workbooks = vbaObject.Workbooks.Open(filename)
 
        For Each Worksheets In Workbooks.Worksheets
            isTextExists = SearchStringInSingleSheet(str, Worksheets)
            If isTextExists Then Exit For
        Next
 
        Workbooks.Close
        Set Workbooks = Nothing
        If Err Then Err.Clear

好了，关于Word和Excel的文字查找的实现代码都有了，接下来是万事俱备只欠东风了，东风就是文件枚举的代码实现。这点我在前面的文章《利用Scripting.FileSystemObject组件来枚举文件》已经介绍过方法了，大家可以移步围观下。

基于上面的工作，下面我实现了一个简单的批量搜索多个Word或者Excel指定的文字的小程序（github gist）供大家参考：
