How to import RichText/rtf and/or HTML content formatting into OpenOffice documents using PyUno

Question

I'm looking to import RichText and/or HTML formatted text into OpenOffice documents, with the PyUno API.

For now, the only solution I've found is to parse the format from source content and applying it to the document using text formatting (cursor's CharFontWeight among other things).

Since OpenOffice already manages text formatting through the clipboard, I would like to know if there already was a proper function or else from PyUno to import the RichText or HTML formatted content.

Thanks!
