Powershell不会读取word文档中的标题文本？

Question

我需要检查大量 word 文档（doc 和 docx）以获取特定文本，并找到了 Scripting Guys 提供的很棒的教程和脚本；

https://blogs.technet.microsoft.com/heyscriptingguy/2012/08/01/find-all-word-documents-that-contain-a-specific-phrase/

脚本读取目录中的所有文档并给出以下输出；

1. 提及次数
2. 找到特定文本的所有文档中的总字数
3. 包含特定文本的所有文件的目录。

这就是我所需要的，但是他们的代码似乎并没有真正检查任何文档的标题，顺便说一下，这是我要查找的特定文本所在的位置。让脚本读取标题文本的任何提示和技巧都会让我非常高兴。

另一种解决方案可能是删除格式，以便标题文本成为文档其余部分的一部分？这可能吗？

编辑：忘记链接脚本：

[cmdletBinding()]
Param(
 $Path = "C:\Users\use\Desktop\"
) #end param

$matchCase = $false
$matchWholeWord = $true
$matchWildCards = $false
$matchSoundsLike = $false
$matchAllWordForms = $false
$forward = $true
$wrap = 1
$application = New-Object -comobject word.application
$application.visible = $False
$docs = Get-childitem -path $Path -Recurse -Include *.docx
$findText = "specific text"
$i = 1
$totalwords = 0
$totaldocs = 0

Foreach ($doc in $docs)
{
 Write-Progress -Activity "Processing files" -status "Processing $($doc.FullName)" -PercentComplete ($i /$docs.Count * 100) 
 $document = $application.documents.open($doc.FullName)
 $range = $document.content
 $null = $range.movestart()
 $wordFound = $range.find.execute($findText,$matchCase,
  $matchWholeWord,$matchWildCards,$matchSoundsLike,
  $matchAllWordForms,$forward,$wrap)
  if($wordFound) 
    { 
     $doc.fullname
     $document.Words.count
     $totaldocs ++
     $totalwords += $document.Words.count
    } #end if $wordFound
 $document.close()
 $i++
} #end foreach $doc
$application.quit()
"There are $totaldocs and $($totalwords.tostring('N')) words"

#clean up stuff
[System.Runtime.InteropServices.Marshal]::ReleaseComObject($range) | Out-Null
[System.Runtime.InteropServices.Marshal]::ReleaseComObject($document) | Out-Null
[System.Runtime.InteropServices.Marshal]::ReleaseComObject($application) | Out-Null
Remove-Variable -Name application
[gc]::collect()
[gc]::WaitForPendingFinalizers()

编辑 2：我的同事想到了调用节标题；

Foreach ($doc in $docs)
{
 Write-Progress -Activity "Processing files" -status "Processing $($doc.FullName)" -PercentComplete ($i /$docs.Count * 100) 
 $document = $application.documents.open($doc.FullName)
 # Load first section of the document
 $section = $doc.sections.item(1);
 # Load header
 $header = $section.headers.Item(1);

 # Set the range to be searched to only Header
 $range = $header.content
 $null = $range.movestart()

 $wordFound = $range.find.execute($findText,$matchCase,
  $matchWholeWord,$matchWildCards,$matchSoundsLike,
  $matchAllWordForms,$forward,$wrap,$Format)
  if($wordFound) [script continues as above]

但这会遇到以下错误：

You cannot call a method on a null-valued expression.

这是正确的方法还是死路一条？

Answer 1

如果你想要标题文本，你可以尝试以下：

$document.content.Sections.First.Headers.Item(1).range.text

Answer 2

对于将来查看此问题的任何人：我上面的代码有些东西不太适用。无论文档的内容如何，​​它似乎都会返回一个误报并设置 $wordFound = 1，从而列出在 $path 下找到的所有文档。

在 Find.Execute 中编辑变量似乎不会改变 $wordFound 的结果。我相信问题可能出现在我的 $range 中，因为这是我在逐步浏览代码时唯一出错的地方。
