The closest I have doesn't account for softwraps, but FWIW:


function fwAnchorTagLine pFldObj, pTag
    local tA
    local tLastLine
    local tNumRuns

    put the styledText of pFldObj into tA
    put item 2 of extents(tA) into tLastLine
    repeat with i = 1 to tLastLine
       put item 2 of extents(tA[i]["runs"]) into tNumRuns
       repeat with j = 1 to tNumRuns
          if pTag is in tA[i]["runs"][j]["style"]["linkText"] \
                AND "link" is not in \
                   tA[i]["runs"][j]["style"]["textStyle"] then
             return i
          end if
       end repeat
    end repeat
end fwAnchorTagLine
