Overview

This operation extracts a subdocument from a document or file. A subdocument is a subsection of a larger document.

Syntax

The syntax for this operation begins with extract subdocument from the document. Nested within this statement, you must specify the subdocument to be extracted.

⚠️ If the subdocument to be extracted is not specified, a question will be raised.

Ways to Specify a Subdocument for Extraction

1. Page Numbers

Specify the start and/or end page numbers of the subdocument:

extract subdocument from the document
    the start page is {start}
    the end page is {end}

2. Start and End Markers

Use textual markers to define where the subdocument begins and/or ends:

Included End Marker

extract subdocument from the document
    the start page marker is "{start marker}"
    the end page marker is "{end marker}"

Excluded End Marker

extract subdocument from the document
    the start page marker is "{start marker}"
    the excluded end page marker is "{excluded end marker}"

ℹ️ Included vs. Excluded End Markers

• An included end marker (or just end marker) includes the specified page in the subdocument.

• An excluded end marker does not include the specified page in the subdocument.

Optional: Specifying the OpenAI Model

Optionally, an OpenAI model can be specified for the document extraction.

the openai model is "{model}"
