Function Details [hide private]

parse(tree, parse_funcs)

source code 

Parse placeables from the given string or sub-tree by using the parsing functions provided.

The output of this function is heavily dependent on the order of the parsing functions. This is because of the algorithm used.

An over-simplification of the algorithm: the leaves in the StringElem tree are expanded to the output of the first parsing function in parse_funcs. The next level of recursion is then started on the new set of leaves with the used parsing function removed from parse_funcs.

Parameters:
  • tree (unicode|StringElem) - The string or string element sub-tree to parse.
  • parse_funcs (A list of parsing functions. It must take exactly one argument (a unicode string to parse) and return a list of StringElems which, together, form the original string. If nothing could be parsed, it should return None.)
