Re: [Zopexmlmethods-users] Install

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

Yes, there are some incompatibilities with current releases of 4suite 
and Zope.
I am currently fixing them and will put out a new release within the 
next month.
The current CVS looks in pretty good shape.  If you don't want to wait, 
you can access the source via anonymous CVS
and try it out.
Best of luck,

[Ken A. <fee...@ya...>]

Hi,

I'm having trouble getting XML-Methods to work.

I installed 4Suite into /usr/local/4Suite-1.0a.4,
using   /usr/local/www/Zope/bin/python setup.py
install

Same procedure with PyXML-0.8.3

I installed ZopeXMLMethods from the Freebsd port, and
that also seems to have worked, as the XSLTMethod and
XML Method Cache Manager are available in the ZMI.
However, when I attempt to add a XSLTMethod, I get the
"No supported XSLT processors available" message.

I suspect this has to do with my PYTHONPATH or
INSTANCE_HOME, which are items have so far evaded my
comprehension. I have googled and re-googled, but now
I humbly ask for some instructions!!! 

Here are my other installation details: 

Zope Version: (unreleased version, python 2.3.4,
freebsd4)
Python Version: 2.3.4 (#2, Sep 6 2004, 12:15:06) [GCC
2.95.4 20020320 [FreeBSD]]
System Platform: freebsd4
SOFTWARE_HOME: /usr/local/www/Zope/lib/python
ZOPE_HOME: /usr/local/www/Zope
INSTANCE_HOME: /usr/local/www/Zope/zope01
CLIENT_HOME: /usr/local/www/Zope/zope01/var 

Thanks in advance,

[Zopexmlmethods-users] How to call XSLTMethod from Python script?

[Phuong N. <phu...@em...>]

   Hi there!
  I have posted the same issue in the discussion forum but receive no response. Anyway, I'd like some help for the
following problem:

 I've written a Python script to call the XSLT Method to transform an existing XHTML document(comments_html) to a new
one, then I want to replace the old one with this new document (write to disk) after transforming. In my script, I
wrote:

  # Locate the source XHTML file in ZODB
  src_obj = context.comments_html

 # Call the XSLT method
 dst_tree = context.append_comment.transform('comments_html')    #not working!!!

 #Update the current comments_html 
 src_obj.manage_upload(dst_tree)

  where 'append_comment' is my XSLT method that is applied to 'comments_html'. However, it doesn't work for me when I
call this XSLT method from Python. I have no idea how to get the result tree (dst_tree) out from Python so that I can
pass its content to the manage_upload(), which will replace the current document's content. 

  Please note: It does work for me when I call this transformation from the ZPT:
  
 <span tal:replace="structure here/comments_html/append_comment">
      The document content is replaced here!
  </span>

 This returns the result tree with the format I want after transforming. I love to see this result from my Python
script too.

  Please help. Many thanks!

[Zopexmlmethods-users] Problem w. CVS release

there is another issue (very strange, and doesn't happen with 1.0.0) - when

(in IE i have to clear my cache, and I can then view it one time).  It does

[Zopexmlmethods-users] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

Thanks for your email. I think what you are trying to do is very reasonable.
Unfortunately, I won't have time to look into this for a few weeks, due 
to an overwhelming

I am planning on putting out a new release for Zope 2.7 and Python 2.3.3

[Zopexmlmethods-users] getting ZopeXMLMethods and python string objects to work together

[Ryan L. <rjlaundr@u.washington.edu>]

Ive been struggling getting ZopeXMLMethods to work correctly in a zope
python script.

 It's the issue of trying to ZopeXMLMethods work with a xml string
object and not a 'real' zope object like DTML method.

I'm basically hooking plone to a database. Im sending an soap xml query
to a database and turning the xml result into xhtml.

=20

Im my script I have=20

result=3Dcontext.doQuery2('gem',context.waterquery3.document_src())

which returns the result xml

How then do I pass this to my xsltMethod (called templatetestxform)?

Wouldn't it nice to be able to call:

 xhtml=3Dcontext.templatetestxform.transform(result)=20

=20

but no dice.

Ive tried to first make the result string into a DTMLmethod, but could
only get=20

context.manage_addDTMLMethod('aSource', '', result)

=20

which work once then complains that the object already exists. This is
also a problem because multi users will be making searches.

=20

=20

Could anyone help me out?

Thanks-

Ryan

Hi Craeg,

thanks for pointing me in the right direction and for the complete
explanation of the issue you gave.

It appears I completely misunderstood your URN resolver implementation
(it was my fault, I should have read the relevant docs more
carefully!!!).

Now everything works like a charm.

Thanks !!

Re: [Zopexmlmethods-users] permission problem when importing xslt

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

Hello:

In order to understand your problem, I would need to see the URL you are 
using for importing.
However, here is some information that might be helpful.

When you make an HTTP request to Zope, you get authenticated.  That 
information is then
a part of the REQUEST parameter.  As long as you hang on to the REQUEST 
parameter,
Zope will use the same authentication information.

However, if you go back out and request a URL directly eg *NOT FROM A 
BROWSER*
such as the following:

xsl:include href="http://www.acme.com/foo/bar.xsl"

you are not using the REQUEST parameter, and Zope will treat this as an 
anonymous
request.  That is because the above statement translates more or less 
directly to the python

urllib.urlopen()

-- please see the Python reference for details. 

In order to avoid this problem, you should use the URN resolver (see the 
documentation)
or relative URLs.  Internally, I made ZopeXMLMethods translate relative 
URLs (or URNs) into Zope
object traversals so that the security context is maintained.  That is 
the *only* way I know
how to maintain the context, otherwise it is lost and you have the 
problem you observed.
While debugging ZopeXMLMethods, I saw this error message many times!

Caveat:  in order to translate relative URLs into Zope traversals, I 
require certain resolver
hooks that are not available in all libraries.  You should check the 
documentation to see if
it is working with the library you are using.  Of course, ZopeXMLMethods 
is being updated,
and the new 1.1 version is not done yet.   I hope to release the new 
version relatively soon,
but have been slammed with lots of client (paying) work recently. 

Hope this helps,

[Zopexmlmethods-users] permission problem when importing xslt

[Giuseppe B. <giu...@ti...>]

Hi all,
I have the following permission problem I am trying to debug and I hope
someone can help.

Here is my situation:
I have a method which call an xslt transform (using
FourSuite11Processor) and everything goes well unless when the xslt
import another xsl via <xsl:import href="..."/> (yes, the URI passed for
resolving imports is correct).

In this case, an extra authorization step is required from within the
python console (_not_ through Zope login widget), after which everything
works normally.

In the log a got the following entry (styleSheet.xsl is the xsl being
imported from the calling xsl):

127.0.0.1  - Anonymous [12/Aug/2003:13:58:25 +0200] "GET styleSheet.xsl
HTTP/1.0" 401 803 "" "Python-urllib/1.15"

Obviously I already authenticated myself when starting the Zope session.

It seems the security context gets lost when importing, but I cannot
understand how can I resolve this.

I am probably missing something very simple, ... but I don't get it !!

Any ideas ?

I am using 1-1-0a.

Thanks,

I submit that the time you spend troubleshooting this
problem may be greater than the time you would spend
to certify the 2.6.1 Zope release.  I have found it
to be a very stable release. 

Why don't you try downloading the ZopeTestCase product
(v0.7 is latest I think) and running all the tests.
Maybe the output will help lead to the problem.
Also, I would make sure you run Zope in debug 
mode and look for error messages.

I don't use Windows XP and haven't used Zope 2.5.0 in
a very very long time.  However, I use Zope 2.6.1 on
Windows 2000 and Red Hat 9 without problems.

Another thing to try: download the latest CVS (1.1a)
of ZopeXMLMethods and see if it provides better
error reporting for you.  It should be pretty robust,
but even if you don't use it for production, it might
be another handy diagnosis tool.  We changed some
things to make it report errors better.

HTH,

My guess is that is the culprit.  Somehow the 4suite
libraries got installed into the wrong python instance.
It sounds like the Zope/python instance is not adding
itself to the windows registry, and the 4suite and pyxml
installations require an instance to be in the registry.
That is bad.

One possibility is to install zope, then REMOVE the python
installation from zope.   That way, you are guaranteed
that every piece of the system (4suite, pyxml, zope) will
use the same installation of python, namely the standalone
one.

------------------------------------------------------------------
I tried everything, uninstalling the standalone Python, registering the Zope
Python (a script I found on the PIL site), forcing Zope to use the
standalone Python..
I tried installing/using Pyana. Same problems.

Then I installed a fresh Zope 2.5.0 on my other XP machine. Same result. And
then........
I installed Zope 2.6.1. on the XP machine (after removing the 2.5.0) with
Pyana and it WORKED. So it has something to do with Zope 2.5.0.
It just won't work with Zope 2.5.0. Can you shed any light on this.
Using 2.6.1 isn't an option for me at the moment. I have to implement an xml
document repository on a Zope 2.5.0 installation. There are several large
projects on this server (wich is not our own server), we can't take the risk
of upgrading now.
So please help!!! I can't do this project without XML-methods (I already
started in March with XML-transform) and there is no 'plan B'.

I believe it is purely an installation issue for win32.
I think it looks for python 2.2 in the registry.
I dunno, I haven't really tried it.  If the latest
releases of libxslt *do* work with python 2.1.x, they
sure don't advertise it...

Actually, according to recent traffic on zope-dev this
problem was recently fixed IIRC.  Further, the fix may have
happened in the 2.6.X branch.  We may yet get Python 2.2
support in the near future!

There are still a lot of problems with Zope 2.X and Python 2.2, even in 
2.7. For example, starting with Python 2.2, builtin types have 
docstrings, thus the ZPublisher can publish them. While everyone agrees 
that the ZPublisher's policy of using the docstring is stupid, the 
problem remains.

No, I would not prefer to do that. See below.

Well, that's a Windows problem. But you did the right thing and pointed 
the libxml installer to your Zope's python (which is likely not 
registered in the registry)

So, where's the problem? Everything's working now. Why should we require 
Python 2.2 then? Most people are running Zope 2.6 with 2.1.3 and just 
because they want to use *one* of many possible XSLT processors, they 
all of a sudden have to switch to Python 2.2 now?

Don't get me wrong, I'm a big fan of Python 2.2 (and 2.3 even more), but 
I believe 2.1 is currently the best platform for Zope 2.

P.S.: I can't see any advancements on the XSLT parameters issue. I have 
safely arrived in Mexico and have some time now. Do you guys still want 
me to tackle this problem?

Thanks for the information!  

You have found an innovative solution 
to the problem that Zope currently does not
support Python 2.2, while the latest libxslt uses it!

I have heard rumors that the next point release of
Zope 2.6 will support Python 2.2, and that would
likely be available in the next 1-3 months.

I think if we release ZopeXMLMethods 1.1 _before_
this happens, we will want to include your information
in the README documentation.  However, I would
prefer to simply switch to Python 2.2 across the
board if possible.

In any event, I am forwarding this message to our
mailing lists in the hope that others might find it
useful in the interim.  Thanks again!

My guess is that is the culprit.  Somehow the 4suite
libraries got installed into the wrong python instance.
It sounds like the Zope/python instance is not adding
itself to the windows registry, and the 4suite and pyxml
installations require an instance to be in the registry.
That is bad.

One possibility is to install zope, then REMOVE the python
installation from zope.   That way, you are guaranteed
that every piece of the system (4suite, pyxml, zope) will
use the same installation of python, namely the standalone
one.

hope this helps,

I have two, one standalone 2.1.2 and the Zope python. The standalone is not
in the path. The Zope one is.
This didn't cause problems before. It worked perfectly with XML-transform
and the Win installers of 4suite and pyxml.
4suite installer won't even install without a python entry in the registry.
The Zope python isn't in the registry it seems.
Long ago I compiled the MySQL extensions succesfully in the same setup.
During compiling pyxml only the Zope python was in the path.
I removed pyxml 0.8.1 (from the control panel in Win2000) before building
and installing pyxml.

> What version of Python is running?  Which version of Zope?

4suite, the one you recommended in combination with pyxml 0.8.2. I
deinstalled the 4suite that worked with XML-transform and pyxml 0.8.1.

Mysql support.

No url, just try to add an xslt method from the add dropdown.

Re: [Zopexmlmethods-users] Re: [Zopexmlmethods-users] install problems

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

We will need more information to help diagnose your problem.

What operating system are you running on?
Are you sure you have only one installed instance of Python on your system?
What version of Python is running?  Which version of Zope?
Which XSLT library are you using?  Which exact version? 
What about other python support libraries (such as pyxml)
What is the exact URL that you type into your browser that results in 
the anomalous behavior?

Given the above information, we can probably find the source of the 
problem pretty
quickly.  That having been said, there are improvements in the CVS for 
how errors are
handled/reported.    Likely the next point release will at least provide 
better
diagnostics for this.

HTH,

[Henny v. d. L. <li...@in...>]

Hi,

Still no succes.

-----------------------------------------------------
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.
-------------------------------------------------------
I did exactly as stated in the readme (btw, remeber  I had no trouble
installing xmltransform).
What do you mean in the readme:  'ensure that ZopeXmlMethods is registered
to use the particular XSLT-processor you wish....' '

--------------------------------------------------------------------
2) Try executing the tests.  If you have ZopeTestCase
installed, you can run the test suite and that will
exercise pretty much everything.
--------------------------------------------------------------------
I ran the testsuite. Ran 45 tests, Ok. No mention however in the tests of
PyXML.

I think we must focus on the fact that xmlmethods exits to nearest
index_html without raising an exception.

Yikes.  This is bad news.  However, please see

I am cc-ing this to the development mailing list.

Zope clearly has different behavior for objects > 64K

> 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 unsu!
 re of where the problem lies -- I have been trying different things in the Zope code (leaving the XML methods untouched).  Any thoughts?

Hum.  Not sure why that wouldn't work.
Have you tried using a DTMLDocument instead of a method?
If not, you might have to send a cut-down example
in order to see what's going on.  
The complexity or degree of recursion really shouldn't
matter.
