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,
<dtml-var dname> <dtml-if expr="_.find(dname, sub[1,6])=='Sunday'"> today is sunday </dtml-if>
this is the error i received when try to view it
Error Type: AttributeError Error Value: find
pls help me out.
try _.string.find() instead of _.find(). It's a string function from the string module.
