Re: [NTG-context] Ctx & XML

Hello Hans,

that already makes assumptions that it's just data ... the context xml
parser is a roundtrip one so a bit more control is provided:

local str = [[
<?xml version="1.0" ?>
<a one="1">
     <!-- rubish -->
   <b two="1"/>
   <b two="2">
     c &gt; d
   </b>
</a>
]]

I've added some flags:

inspect(xml.totable(xml.convert(str)))

table={
  {
   "xml version=\"1.0\" ",
   ["_type"]="instruction",
  },
  "\
",
  {
   "\
     ",
   {
    " rubish ",
    ["_type"]="comment",
   },
   "\
   ",
   {
    ["_tag"]="b",
    ["_type"]="_element",
    ["two"]="1",
   },
   "\
   ",
   {
    "\
     c > d\
   ",
    ["_tag"]="b",
    ["_type"]="_element",
    ["two"]="2",
   },
   "\
",
   ["_tag"]="a",
   ["_type"]="_element",
   ["one"]="1",
  },
  ["_type"]="root",
}

inspect(xml.totable(xml.convert(str),true))

table={
  {
   "xml version=\"1.0\"",
   ["_type"]="instruction",
  },
  {
   {
    "rubish",
    ["_type"]="comment",
   },
   {
    ["_tag"]="b",
    ["_type"]="_element",
    ["two"]="1",
   },
   {
    "c > d",
    ["_tag"]="b",
    ["_type"]="_element",
    ["two"]="2",
   },
   ["_tag"]="a",
   ["_type"]="_element",
   ["one"]="1",
  },
  ["_type"]="root",
}

inspect(xml.totable(xml.convert(str),true,true))

table={
  {
   [0]="a",
   {
    [0]="b",
    ["two"]="1",
   },
   {
    [0]="b",
    "c > d",
    ["two"]="2",
   },
   ["one"]="1",
  },
}

The last one is yours. Of course in all cases you loose info that is
present in the original representation (where you can also access the
nodes via expressions). Don't expect additional helpers for this
'totable' variant.

this is great. I'll try it...

Thank you.

BTW: In your example, you are using the following enum of "_type":

"instruction",
"comment",
"_element", <-- REALLY UNDERSCORE here?
"root",

Best regards,

Lukas

Hans
