PowerShell Requires Chilkat v11.7.0+

See more PDF Text Extraction Examples

Demonstrates "labelValue": "section", which returns everything from a heading up to the next heading of the same or higher level. With the "markdown" operation the section keeps its own sub-headings. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

#  The PDF used in this example is available at sectioned_doc.pdf

$pdf = New-Object Chilkat.Pdf
$success = $pdf.LoadFile("qa_data/pdf/sectioned_doc.pdf")
if ($success -eq $false) {
    $($pdf.LastErrorText)

$json = New-Object Chilkat.JsonObject
$jsonOut = New-Object Chilkat.JsonObject

#  The document has the sections Introduction, Opening Hours, Terms and Conditions (with the
#  sub-sections Admission, Safety and Liability) and Contact.  Get the Terms and Conditions:
#  everything after that heading up to the next heading of the same level (Contact).  The heading
#  itself is not part of the value; labelMatches[0].label has it.
$json.UpdateString("label","Terms and Conditions")

$success = $pdf.ExtractText("markdown",$json,$jsonOut)
if ($success -eq $false) {

$($jsonOut.StringOf("markdown"))

#  The same with the "text" operation gives the section as plain text.
$success = $pdf.ExtractText("text",$json,$jsonOut)
if ($success -eq $false) {

}

#  Sample output:

#  ### Admission
#  
#  Admission is free. Groups of more than ten should book in advance so that a volunteer can be assigned to them.
#  
#  ### Safety
#  
#  No more than eight people may be on the stair at one time. Children under twelve must be accompanied by an adult, and the lantern room is closed in high winds.
#  
#  ### Liability
#  
#  Visitors climb the tower at their own risk. The society carries public liability insurance but accepts no responsibility for personal property.
