Markdown 'page_break_placeholder' throwing error

[jai-uparkar]

Hi!

Currently using docling to parse pdfs and exporting content as markdown. However, I have a need to get the text for each page.

Environment: docling: 2.28.2, python: 3.9.19

Looking at the docling documentation, the 'export_to_markdown' accepts a page_break_placeholder argument. However when I'm using this parameter, i get an error:
TypeError: export_to_markdown() got an unexpected keyword argument 'page_break_placeholder'

Can someone help me resolve this?

this is my code:

from docling.document_converter import DocumentConverter

# Initialize the DocumentConverter
converter = DocumentConverter()

# Load the PDF file
pdf_path = "/Users/jaiuparkar/Downloads/sample-local-pdf.pdf"

# Convert the PDF into a Docling document
docling_document = converter.convert(pdf_path)

# Iterate through each page and export it to Markdown
md = docling_document.document.export_to_markdown(page_break_placeholder="<!-- page -->")
print(md)

@jai-uparkar can you share the output of docling --version?
I assume the docling-core version in your environment is prior to v2.24.0 — which introduced the feature.
In that case, make sure you have an up-to-date docling-core version, e.g. if you are using pip: pip install --upgrade docling-core

For context: this new parameter, as most DoclingDocument-based capabilities, is directly provided by the docling-core package (which is a dependency of the docling package), so what matters here is the version of docling-core you have installed. Running docling --version reports all of these versions.

• If you (freshly) installed docling after March 25, you must have automatically gotten a docling-core version including this feature
• Otherwise you would need to update your docling-core as outlined above

Got it, thank you!

Just for clarity, I have used docling version 2.28.2

See my clarification above.

It was working fine for me.

All my docling dependency versions.

docling==2.28.2
docling-core==2.24.0
docling-ibm-models==3.4.0
docling-parse==4.0.0
