XML Mapfile transformation issues with expressions and symbol

[aboudreault]

Alexandre Soares has reported these two issues with the XML transformation:

• When I transform my xml map file to a map file, my expressions that contain a regular expression (the same is true for filters) are rendered with double quotes (because the stylesheet has the quote="1" param for those templates).

• The symbol attribute (which does not get quoted by default) causes a problem if the value references a symbol's name.

Two new types have been added in the xml schema:

• expressionType

  <expression type="CONSTANT">583</expression> or <expression>583</expression> (quoted)
  <expression type="REGEX">/.../</expression> (not quoted)
  <expression type="MSEXPR">(...)</expression> (not quoted)
  

• symbolType

  <symbol type="NAME">star.gif</symbol> (quoted)
  <symbol type="ID">32</symbol> (not quoted)
  

Fixed and committed in r9973. I'm waiting the Alexandre's test to backport this in 5.6.

Another fix about the transformation when the type is not specified in the <expression> has been committed in r9982. Backported in 5.6 branch in r9983.
