How to convert HTML file into Framemaker Interchange Format(.mif) file?

• I want to mark index and cross-references like Framemaker does.
• Framemaker can export the .fm into .htm and .mif file.
• I have analyzed how the index and cross-references appears in .htm and .mif file after exporting it from framemaker.
• Now my system will produces .htm file and I can manage to mark the index and cross-reference like framemaker does.
• I want that framemaker retain the index and cross-references which will be marked by my system.
• But there is no way to import or open HTML files directly in Framemaker.
• We can import .mif file in framemaker.
• So is there any way we can convert HTML files into .mif(FrameMaker Interchange Format).

there is one option, I know its not full proof solution for this problem. but it can save your efforts to some point,

1. Save the HTML file to RTF format (using MS word/Open Office)
2. Open that RTF file in FM
3. FM accepts the RTF file and convert it into .fm file
4. Save the .fm file into .mif format

Note : in this conversion, some data loss may happen, i have tried using it for Markers it works but not complete solution.

All the best!!
