How can I edit an RH9 .hhc file (XML format) to include a portion of a RH8 TOC (HTML format)?

Question

I blend output from a third-part application (Sandcastle) into an existing RH8 project.  I do this by decompiling and importing the HTML, then editing the RH8 .hhc file to include the .hhc information from Sandcastle.
This worked fine until RH9 (and now RH10), where the format of the .hhc changed to XML.  Can someone tell me how to approach this now?  Currently, I worked around this by creating a RH8 project with the imported HTML/hhc from Sandcastle, then upgraded that project to RH9.

Answer 1

I decompile the CHM file produced by Sandcastle because Sandcastle output does not provide an index file (.hhc) that I can use to edit the main TOC in my RoboHelp project.
The Sandcastle HTML output files that I import into Robohelp have very intricate nesting and hyperlinking, so autogenerating a TOC in RoboHelp does not produce the desired results. Decompiling is the only way I see to obtain an index file that Robohelp will recognize and add/edit to the existing TOC.
This may be ignorance on my part, but I can't look at an HTML-based .hhc (RH8) and know how to edit it to be XML-based (RH9).
See below for examples.
