===========================================================

Describe the Bug

When processing markdown using the partition_md function, the title 'section' is not properly placed under its parent 'Chapter 1'. Instead, it is assigned a NaN value. This issue may be caused by a missing parameter or an incorrect configuration in the partition_md function.

To Reproduce

The following code snippet reproduces the issue:

markdown_document = """# Title\n\n \
## Chapter 1\n\n \
Hi this is Jim\n\n Hi this is Joe\n\n \
### Section \n\n \
Hi this is Lance \n\n
## Chapter 2\n\n \
Hi this is Molly"""

from unstructured.partition.md import partition_md
from unstructured.staging.base import convert_to_dataframe

# file = r"C:\Users\Cjy\Desktop\fix\out.md"
raw_md_elements = partition_md(text=markdown_document)
df = convert_to_dataframe(raw_md_elements)
df

Expected Behavior

The expected behavior is that the 'section' title should be placed under its parent 'Chapter 1' in the markdown hierarchy. The partition_md function should correctly identify the parent-child relationships between titles and assign the correct values.

Screenshots

Unfortunately, there are no screenshots available to illustrate this issue.

Environment Info

To better understand the environment in which this bug occurred, we ran the python scripts/collect_env.py command and obtained the following output:

Python 3.9.7 (default, Sep  1 2021, 10:08:22) 
[GCC 9.3.0]
Platform: win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import unstructured
>>> unstructured.__version__
'0.12.5'

Additional Context

The version of the unstructured library used in this environment is 0.12.5.

Possible Causes

There are several possible causes for this issue:

Missing Parameter: The partition_md function may require additional parameters to correctly handle title hierarchy. We may need to investigate the function's documentation to determine if any parameters are missing.
Incorrect Configuration: The partition_md function may have incorrect configuration settings that are causing the issue. We may need to review the function's configuration options to determine if any settings need to be adjusted.
Bug in partition_md Function: The partition_md function may contain a bug that is causing the issue. We may need to investigate the function's code to determine if any bugs are present.

Solution

To resolve this issue, we need to investigate the partition_md function and determine the cause of the problem. We may need to add additional parameters, adjust configuration settings, or fix bugs in the function to correctly handle title hierarchy.

Step 1: Investigate `partition_md` Function

We will start by investigating the partition_md function to determine if any bugs or incorrect configuration settings are present.

Step 2: Review Function Documentation

We will review the function's documentation to determine if any additional parameters are required to correctly handle title hierarchy.

Step 3: Test Function with Different Parameters

We will test the function with different parameters to determine if any settings need to be adjusted.

Step 4: Fix Bugs in `partition_md` Function

If any bugs are found in the partition_md function, we will fix them to ensure that the function correctly handles title hierarchy.

Step 5: Verify Solution

Once the solution is implemented, we will verify that the issue is resolved and that the partition_md function correctly handles title hierarchy.

Conclusion

In conclusion, the partition_md function does not properly handle title hierarchy, resulting in the 'section' title being assigned a NaN value. We have identified several possible causes for this issue, including missing parameters, incorrect configuration settings, and bugs in the function. We will investigate the function and implement a solution to resolve this issue.
