[Zopexmlmethods-users] Strange Behavior with XML files >= 64k

[M K <mat...@ya...>]

Ever since this wonderful product has been released, I have been playing with it, and have come to a bump in the road that I simply can't get over. Here is the basic problem, let's say I have a folder called "forest" and I am populating "Forest" with uploaded files (or Add --> File in the ZMI).  Works fine, so cool -- I can FTP these trees into my forest and each renders beautifully with the magic of a modular XML transformer. OK, so it works fine _if_ the XML files are under 64Kbytes.  If I try to process a freshly uploaded file, it hangs and eventually spits out "EOF reached" in the zope stupid log. As if this wasn't strange enough...  It continues -- so I 'modify' the OFS fileEdit.dtml page to allow me to directly edit the text of the XML file (it won't normally display if the text is >= 64K).  So I make absolutely NO changes whatsoever to the XML on the screen and click "Save Changes".  If I slap my modularxform at the end of the URL, the transform works. So, I am unsure of where the problem lies -- I have been trying different things in the Zope code (leaving the XML methods untouched).  Any thoughts?

[Craeg S. <cs...@ar...>]

One possibility is that you have two
different installations of python.  4Suite might
be installed in one, but not the other.

Unfortunately, this is easy to do, because Zope tends
to install its own version of Python, and it requires
version 2.1.3 (for example, most Linux systems come with 
Python 2.2 already installed and in the default path)

The basic requirement is: you must use a single Python 2.1.3
installation to:
- start zope
- install pyxml and 4suite into
- run the tests

Let me know if these helps, otherwise we can try 
the next step.

[Craeg S. <cs...@ar...>]

Two things to try:

1) go through the TUTORIAL step by step and make sure
that the installation is sound.  If the very first
example doesn't work, either the TUTORIAL is not clear
enough (documentation bug) or your installation is not
setup correctly.

2) Try executing the tests.  If you have ZopeTestCase
installed, you can run the test suite and that will
exercise pretty much everything.

Let me know if you need help setting up the test suite.

[Zopexmlmethods-users] How to register XSLT transformer?

[peter v. h. <pe...@va...>]

Dear all,

I have downloaded and installed ZopeXMLMethods. Latest 4Suite was already installed.
I ran the testsuite: no problems, 43 tests OK, but when I follow the tutorial and make the XSLT method Zope complains that there is no XSLT processor available. How come?

cheers,

peter

Craeg,


Installing PyXML-0.8.2 doesn't help. It still exits to the nearest
index_html when I try to add an xslt-method.

[Craeg K S. <cs...@ar...>]

Yes, this is a royal pain.  I can't WAIT until Zope 2.7 is released with 
its
support/requirement for Python 2.2  

Definately it is the PyXML issue.  There are serious problems with 0.8.1
PyXML 0.8.2 is fairly easy to install, even from source.  Assuming 
Python is on your path:

cd c:\pyxml-0.8.2
python setup.py build
python setup.py install

If python is *not* on your path, it would be something like

c:\zope\bin\python setup.py build
c:\zope\bin\python setup.py install

That should do it.    If it doesn't, we can try more extensive debugging 
techniques;
please let me know.

BTW, did you see our new support mailing list?

I am forwarding this message to the list, so that others might benefit 
from this solution..

I am sending this to the ZopeXmlMethods-user list,
in hopes others may find it useful.
