luaxml 总是以一个字母缩进输出

Question

我有一个代码来处理 xml 文件并用其内容填充 tcolorboxes。我正在使用 luaxml，但似乎我总是得到一个字母缩进。需要最新的 luaxml。代码在这里，最后给出了输出的图片：

\tcblower和之间的换行符@{body}是造成虚假空白的原因：

local domobject = require "luaxml-domobject"
local transform = require "luaxml-transform"

-- module
local M = {}

-- template for SMS print
local other_template = [[
\bubble{\raggedright @{contact_name} $\langle$@{address}$\rangle$}{
\raggedright\footnotesize subject:@{subject}, read: @{read}
@{readable_date}
\tcblower @{body}}
]]

transform.add_action("sms[type='1']", other_template)

M.process_xml = function(filename)
  local f, message = io.open(filename, "r")
  if not f then 
    print("XML file error: ", message)
    return nil, message
  end
  local content = f:read("*all")
  f:close()
  content = content:gsub("\r", "")
  local dom = domobject.parse(content)
  local converted = transform.process_dom(dom)
  tex.print(converted)
end

return M
