bool xpath_processor::o_check_predicate ( TiXmlElement *  XEp_child,
bool  o_by_name 
) [protected]

Spec extract :
A PredicateExpr is evaluated by evaluating the Expr and converting the result to a boolean. If the result is a number, the result will be converted to true if the number is equal to the context position and will be converted to false otherwise; if the result is not a number, then the result will be converted as if by a call to the boolean function. Thus a location path para[3] is equivalent to para[position()=3].

void xpath_processor::v_function_equal ( expression_result **  erpp_arg  )  [protected]

This function is for internal use : evaluation of an equality expression
Standard excerpt :

If both objects to be compared are node-sets, then the comparison will be true if and only if there is a node in the first node-set and a node in the second node-set such that the result of performing the comparison on the string-values of the two nodes is true.

If one object to be compared is a node-set and the other is a number, then the comparison will be true if and only if there is a node in the node-set such that the result of performing the comparison on the number to be compared and on the result of converting the string-value of that node to a number using the number function is true.

If one object to be compared is a node-set and the other is a string, then the comparison will be true if and only if there is a node in the node-set such that the result of performing the comparison on the string-value of the node and the other string is true.

If one object to be compared is a node-set and the other is a boolean, then the comparison will be true if and only if the result of performing the comparison on the boolean and on the result of converting the node-set to a boolean using the boolean function is true.

When neither object to be compared is a node-set and the operator is = or !=, then the objects are compared by converting them to a common type as follows and then comparing them.

  • If at least one object to be compared is a boolean, then each object to be compared is converted to a boolean as if by applying the boolean function.
  • Otherwise, if at least one object to be compared is a number, then each object to be compared is converted to a number as if by applying the number function.
  • Otherwise, both objects to be compared are converted to strings as if by applying the string function. The = comparison will be true if and only if the objects are equal; the != comparison will be true if and only if the objects are not equal.
  • Numbers are compared for equality according to IEEE 754.
  • Two booleans are equal if either both are true or both are false.
  • Two strings are equal if and only if they consist of the same sequence of UCS characters.

Standard excerpt :

void xpath_processor::v_order_tree (  )  [protected]

flag that says if the tree has been ordered already. This is a rather slow process, so we only do it if needed

Order the tree : assign an integer to all nodes based on the document order
Right now, tinyxml doesn't have a user value associated to attributes ... arrrgh. We order everything else, and will have to compute attributes order on demand
