After spending most of three or four days, with the occasional assistance of Greg and Clifton, I produced a well-formed xml structure and a tab delimited file derived from the original rtf file for the 1790s capital trials. There were 80 recorder's reports covering 757 trials.
About 35 of the recorder report lines have some content in the "miscellaneous text" element/field, so those will have to be edited by hand. At least one of those lines includes a reference to a second recorder's report.
About 250 of the trials have some content in the "miscellaneous text" element/field, so obviously those will need manual editing. I have no idea how many trials have syntactically OK but nonsensical values in fields.

I removed the list of "respited larcenies" and have not dealt with them yet.
