Detailed Description

A token list class. This is the output of the lexical analysis
Note that the empty list consist of a single null element in order to speed up later insertions

Here is the caller graph for this function:

void TinyXPath::token_list::v_tokenize_expression

(

)

Decodes an XPath expression, further manipulating a token list
On input, we have a list of basic lexical tokens. We only merge here the multiple tokens : like '::' or '!='. We also delete whitespace tokens
