Hi @Doge2077! I'm Dosu and I’m helping the MinerU team.
This repeated escaping of < and > in HTML tables in MinerU VLM mode was a known issue in version 2.0.x. The root cause is that the escaping function was applied multiple times to already-escaped content, resulting in &lt; and &gt; instead of the correct < and >. This was fixed in MinerU 2.1.6 by refactoring the VLM backend to use a new function (block_content_to_html) for table HTML conversion, which prevents repeated escaping. The patch also improved table HTML extraction logic.
To resolve this, upgrade MinerU to at least version 2.1.6. If upgrading is not possible, you can manually apply the patch by updating the VLM backend code to use block_content_to_html for table content conversion and ensure only the <table>...</table> portion is extracted for table results. Details of the fix and code changes are in the release PR.
MinerU 2.0.x does not contain this fix, so the issue will persist until you upgrade or patch. If you need help with the manual patch, let me know!
To reply, just mention @dosu.
