Hi Hamzat, DTML is only a template language meant to place expressions inside HTML or any text and simple floating control. Whatever is placed in an expr=" " attribute (implicit with only " ") is a python expression. What you are writing in here is pure python. However, the use of python in this expression is a bit limited for security reasons. To make modules available to the expression, they are appended to the namespace which is represented by an underscore _ Available modules are whrandom, string, ... the string module in turn defines various functions which you can use. Refer to the python documentation for a complete list. (http://www.python.org/ -> Documentation -> Library ... -> String Module ) Your find is available as _.string.find() inside an Expression. However I strongly recommend not (I mean not!) use too much code inside DTML. Try to get more familar with python (mostly the tutorial in the documentation on python.org will do for a start) And try to write all the logic in PythonScripts. What seems harder at first will sure pay off in the end. Good luck Tino --On Montag, 13. August 2001 13:02 +0200 Hamzat kamal <hamzatk@dnetsystems.net> wrote:

Dear tim,
I checked through the DTML function i could not find this function. I am writing a code where i will need to store the title of each dtml document with <dtml-let > and extract certain number of xters from the title and test it before calling a particular object.
This function is widely used, but this is the way is been used in Vb
mid(string, start [,length]) string - denote the var name start - " where you want to begin the extraction length - " the no of xters you want extract from the string
You would use the Python string module for this.
I am also completely new to Python, but when checking the zope doc (AppendixA.htm) i saw one DTML string function find(s, sub[start [,end]]) :- Returns the lowest index s where the substring sub is found such that sub is wholly contained in s[start:end].
I assumed this will serve my purpose but when i tried it, this is the error i received when try to view it
Error Type: AttributeError Error Value: find
pls help me out.
