Re: [staf-users] python built-in method not recognized?

Here's an example of how to use the Python string find method:

  <script>
    str = 'c:/foo/bar/hi.there'
    n = str.find('hi')
  </script>

Re: [staf-users] python built-in method not recognized?






Thanks.  I seem to have problems with Python 2.1 methods as well, though.  
In particular, I am trying to find if a given substring exists in a string 
using the find() function, which according to 
http://www.python.org/doc/2.1.3/lib/string-methods.html should work in 
2.1.  The following test function yields the below results.  Am I missing 
something?

Thanks again,

- Stephan


    <function name="substring">
        <sequence>
            <script>
                str = 'c:/foo/bar/hi.tere'
                n = find(str, 'hi')
            </script>
            <message>'Found at position: %s' % n</message>
        </sequence>
    </function>

That's because stf.rpartition was added in Python 2.5.  It's not available 
yet in Jython.  STAX uses Jython 2.1, not Python to run Python code in a 
STAX script.  The Jython developers are currently working on beta releases 
for Jython 2.5.  Sometime after Jython 2.5 GAs, we plan to update STAX to 
include Jython 2.5, not Jython 2.1. 

 See "Appendix F: Jython and CPython Differences" in the STAX User's Guide 
for more information.

[staf-users] python built-in method not recognized?








Hi there,

the following little test of python's built-in str.rpartition appears to 
not be recognized when running this through a STAX script, as the below 
error suggests.  Any idea what I'm missing to get this to execute as 
expected?

Thanks,

- Stephan



    <function name="rpartition">
        <sequence>
            <script>
                str = 'c:/foo/bar/hi.tere'
                segments = str.rpartition('/')
            </script>
            <message>segments[0]</message>
            <message>segments[2]</message>
        </sequence>
