Powershell在Word文档中搜索匹配字符串

问题描述：

我有一个简单的要求.我需要在Word文档中搜索一个字符串，结果需要在文档中找到匹配的行/一些单词.

I have a simple requirement. I need to search a string in Word document and as result I need to get matching line / some words around in document.

到目前为止，我可以在包含Word文档的文件夹中成功搜索字符串，但是它会根据是否可以找到搜索字符串返回True/False.

So far, I could successfully search a string in folder containing Word documents but it returns True / False based on whether it could find search string or not.

$files    = Get-Childitem $path -Include *.docx,*.doc -Recurse | Where-Object { !($_.psiscontainer) }
$output   = "c:\wordfiletry.txt"
$application = New-Object -comobject word.application
$application.visible = $False
$findtext = "CRHPCD01"

Function getStringMatch
{
  # Loop through all *.doc files in the $path directory
  Foreach ($file In $files)
  {
   $document = $application.documents.open($file.FullName,$false,$true)
   $range = $document.content
   $wordFound = $range.find.execute($findText)

   if($wordFound) 
    { 
     "$file.fullname has $wordfound" | Out-File $output -Append
    }

  }
$document.close()
$application.quit()
}

getStringMatch

import-csv $output

有两种方法可以获取您想要的东西.一种简单的方法是，因为您已经拥有文档的文本，可以对它执行正则表达式匹配并返回结果等等.这有助于尝试解决在文档中出现一些单词的问题.

There are a couple of ways to get what you want. A simple approach is since you have the text of the document already lets perform a regex match on it and return the results and more. This helps in trying to address getting some words around in document.

我们有变量$charactersAround，它设置要匹配$findtext的字符数.另外，尽管我的输出更适合CSV文件，所以我使用$results捕获属性的哈希表，最后将这些属性输出到csv文件.

We have the variable $charactersAround which sets the number of characters to match around the $findtext. Also I though the output was a better fit for a CSV file so I used $results to capture a hashtable of properties that, in the end, are output to a csv file.

请确保为您自己的测试更改变量.现在，我们使用正则表达式来定位匹配项，这将打开一个无限的可能性.

Be sure to change the variables for your own testing. Now that we are using regex to locate the matches this opens up a world of possibilities.

示例输出

Match TextAround                                                        File                          
----- ----------                                                        ----
