Parse a String given some delimiters

[Alfred Newman via Digitalmars-d-learn]

Hello,

I'm migrating some Python code to D, but I stuck at a dead end...

Sorry to provide some .py lines over here, but I got some doubts 
about the best (fastest) way to do that in D.

Executing the function parsertoken("_My   input.string", " _,.", 
2) will result "input".
Parsercount("Dlang=-rocks!", " =-") will result 2,

def parsertoken(istring, idelimiters, iposition):
"""
Return a specific token of a given input string,
considering its position and the provided delimiters

:param istring: raw input string
:param idelimiteres: delimiters to split the tokens
:param iposition: position of the token
:return: token
"""
	vlist=''.join([s if s not in idelimiters else ' ' for s in 
istring]).split()
	return vlist[vposition]

def parsercount(istring, idelimiters):
"""
Return the number of tokens at the input string
considering the delimiters provided

:param istring: raw input string
:param idelimiteres: delimiters to split the tokens
:return: a list with all the tokens found
"""
	vlist=''.join([s if s not in vdelimiters else ' ' for s in 
istring]).split()
	return len(vlist)-1
	
		
Thanks in advance
