Re: [xml-dev] Schematron and RNG, RNC

[Alex Muir <alex.g.muir@gmail.com>]

Thought it a bit interesting that when converting 

    <s:pattern id="condition.checks">
      <s:title>Whenever condition attribute is used the element should have have an xml:id or cref
        attribute</s:title>
      
      <s:rule context="*[exists(@condition)]">
        <s:assert test="exists(@cref) or exists(@xml:id)">There should be an xml:id or cref
          attribute</s:assert>
      </s:rule>
    </s:pattern> 



with trang I get this lovely concoction,,




s:pattern [
  id = "condition.checks"
  "\x{a}" ~
  "      "
  s:title [
    "Whenever condition attribute is used the element should have have an xml:id or cref\x{a}" ~
    "        attribute"
  ]
  "\x{a}" ~
  "      \x{a}" ~
  "      "
  s:rule [
    context = "*[exists(@condition)]"
    "\x{a}" ~
    "        "
    s:assert [
      test = "exists(@cref) or exists(@xml:id)"
      "There should be an xml:id or cref\x{a}" ~
      "          attribute"
    ]
    "\x{a}" ~
    "      "
  ]
  "\x{a}" ~
  "    "
]


I've since formated the rng without as many line breaks below which is a bit better but I gather Trang likes adding escaped newlines \x{A} to the rnc.. 

this can all be stripped? 

  "\x{a}" ~
  "    "

Regex to the rescue? or am I doing something wrong?

thanks

Clunky, but usable.  Trang understands this syntax when converting from
RNG to RNC and vice versa.
