How to export properties to a text file via a template

The first step is to create a template, the format of the template is quite flexible. In this example the following html template is used:

<html>
 <table border="1">
  <tr>
   <td>{Author}</td>
   <td>{Classification}</td>
   <td>{Created By}</td>
  </tr>
 </table>
</html>

The following script will then replace the property names with their corresponding values:

$templatePath = "C:\temp\template.txt"
$destinationPath = "C:\temp\template.html"

$regex = [regex]"\{+(?i)\b[A-Z\s]+\b\}"
$template = Get-Content -Path $templatePath
$propertyMatches = $regex.Matches($template)
foreach($propertyMatch in $propertyMatches){
    $propertyName = $propertyMatch.Value.Trim( @('{','}') )
    $propertyValue = $file.$propertyName
    $template = ($template -replace $propertyMatch.Value, $propertyValue)
}
Write-Host $template
$template | Out-File $destinationPath -Append

Define the template file that should be used
Define the destination file that should be created / appended to
Match the regex against the content of the template file to find the required properties
Replace all the property names in the template file with their actual values
Write the result to the destination file

Example

Using the template shown before the output should look similar to this:

<html>
 <table border="1">
  <tr>
   <td>Assembly1.dwg</td>
   <td>Design Document</td>
   <td>Administrator</td>
  </tr>
 </table>
</html>

Remarks

This code snippet will always use the same destination file and append to it.
