This filter will remove all empty Spans with id starting with x. Save as 
"removeXSpans.lua':

function Span(el)
return #el.content == 0 and el.identifier:match('^x%d') and pandoc.Space()
or el
end

And run pandoc with the `-L removeXSpans.lua` option, e.g. 
pandoc -f dockbook sourcefile -t markdown -o outfile.md -L removeXSpans.lua

Result:
# 1 Introduction

However, this will break any link to #x1-10001. If there are internal links 
in the doc (e.g. from the table of
content) that you need to preserve, you need a filter that produces instead:
# 1 Introduction {#x1-10001}

Perhaps this will work (it'd help to have a sample docbook source), saved 
as removeXSpans.lua and used as above

function Header(hd)
local id = ''
hd.content = hd.content:walk {
Span = function(el)
if #el.content == 0 and el.identifier:match('^x%d') then
id = el.identifier
return pandoc.Space()
end
end
}
print(id)
if id ~= '' then 
hd.identifier = id
return hd
end
end
