Subject: [Zope-xml] I've got ParsedXML...now what?
Message-ID: <Pine.GSO.4.21.0112021820020.4141-100000@isis.visi.com>

Hi everyone,

I've just subscribed to the list and I'm hoping to get some basic starter
info about using ParsedXML or any other XML tool in Zope.

I want to build a simple tool that our school's librarians can use to
publish useful links for teachers and their students' projects. For example,
a science teacher may want to publish a collection of earthworm-related
links for a research paper her students are writing.

I've installed ParsedXML and I've uploaded a bookmarks file in XBEL format
to Zope. Now I need to know how to display them. I've searched Zope.org
looking for relevant How-Tos, but I came up empty.

Can anyone provide any tips or suggest some reading that would give me some
insight? Any example code would be appreciated.

-Tim

Really, in my experience, all of the power of ParsedXML comes from using
the DOM interfaces.  The DOM specification is available from the W3C
(www.w3c.org).  If you follow the interfaces, you will figure out how to
get around using the DOM.  Another good place to start is by looking at
the example DTML that comes with the ParsedXML product.  Import it and
start playing/learning.  

It was my experience that it is a very steep learning curve to figure
out how to use ParsedXML.  I still don't think I'm doing it right, but
it works.  :-)  Start simple and build off of it.  You have a good XML
example to start from, with your bookmarks.  Just take it slow and make
it do what you want.

Good luck, and if you have questions about exactly where to start, I may
be able to tell you where I began.  Try the w3c first though.

I'm just guessing wildly, but is it possible your version of Python is
not compiled to use threads?

Message-ID: <20011206172332.A19251@vet.uu.nl>

Hey there,

Some progress:

  * I hooked my NodePath implementation into ParsedXML. Currently 
    only ChildId paths (path to node using child node indexes) and
    RobustPaths (paths to nodes using heuristics to be more resilient
    to changes to the structure of the document) are supported. I'm 
    working on using Element Ids (see next entry) as well, and it shouldn't
    be hard to plug in other schemes. The urls do look pretty funky,
    though, but it was the only solid way I could integrate them with
    Zope that I've found.

  * I've finished up implementing element_ids for ParsedXML's core DOM.
    It also works for cloneNode and importNode now. I know this (reasonably
    certain) because I implemented a unit test suite for element ids. :)

Next step is to merge both changes into the ParsedXML trunk, which are
both sitting in separate branches right now. Unless someone objects to them. 

The branches are:

faasen-parsedxml_node_id-branch (for element ids)

faassen-parsedxml-nodepath-branch (the node path framework) 

Regards,

Martijn

I haven't tried it yet. I can't think of anything that would break, 
as the Python version is the same as for Zope 2.4, but best way would be to 
try it out. Let me know if there are any problems.

Eventually I'll get to running its unit tests in Zope 2.5 myself. Not
that the failing of unit tests necessarily indicates bad trouble; far too
many are failing now... I'm still hoping on a clue on why the parser
unit tests crash under some circumstances.

Martijn

Message-ID: <Pine.GSO.4.21.0112071525540.25902-100000@isis.visi.com>

Hi everyone,

I'm interesting in learning to manipulate XML with Python. Eventually I'd
like to build a Zope app for manipulating and publishing bookmarks (probably
using the ParsedXML product at this point).

I've got a Debian Linux system here with all the python-related XML packages
installed. I also read the Python/XML HOWTO (Release 0.6.1, March 20,
2001) and Fred Drake's description of XBEL.

I'm having trouble getting the simplest little script to work. It seems like
there are many different modules to use and I'm not having any luck even
importing them.

wilsont@galileo:~$ python
Python 2.1.1 (#1, Nov 11 2001, 18:19:24)
[GCC 2.95.4 20011006 (Debian prerelease)] on linux2
Type "copyright", "credits" or "license" for more information.
>>> from xml.dom.ext.reader.Sax import FromXmlFile
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: No module named ext.reader.Sax
>>>

At this point, I'd like to find a very simple piece of code that will load a
tiny little XBEL-formatted bookmark file and create a DOM tree.

Any pointers?

-Tim

Well, ParsedXML can do that, even without Python XML. You can do this
in Zope (easily, create a ParsedXML object), or from the commandline. 
There are some examples on what to do in the unit test directory. I'll
also post an example:

from Products.ParsedXML.DOM import ExpatBuilder

file = open('myxbelfile', 'r')
doc = ExpatBuilder.parse(file)
file.close()

This takes a file-like object and builds a ParsedXML DOM tree from it
using Expat. 'doc' now should refer to the document node, so you can
do stuff like this:

doc.documentElement.appendChild(doc.createElement('foo'))

to add a 'foo' element to the end of the list of child nodes.

Martijn

Subject: [Zope-xml] ZPT + ParsedXML strangeness (acquisition vs. getattr)
Message-ID: <3C11816A.8030805@pastelhorn.com>

Hi -- here's a strange behaviour using Page Templates and ParsedXML.

The files (also in wilm.nl/test with u/p faassen:faassen):

--- xml : ParsedXML ---------------------------------------------
<?xml version="1.0" ?>
<doc>
   <a>a elm 1</a>
</doc>

--- pt_een : ZPT -------------------------------------------------
<div tal:repeat="a python:here.xml[0].getElementsByTagName('a')">
  <div tal:content="structure a/pt_twee">a/pt_twee</div>
</div>

--- pt_twee : ZPT ------------------------------------------------
something
------------------------------------------------------------------

Calling:
   xml/pt_een

results in:

  if I'm logged in as 'manager':
    "something"  # this is correct

  if I'm not logged in:
    "Error Type: TALESError
     Error Value: exceptions.ValueError on invalid literal for int():
                  pt_twee in "<PathExpr standard:a/pt_twee>"


Now, creating a "Script (Python)" with proxy 'manager':

--- py : Script (Python) -----------------------------------------
return context.xml.pt_een()
------------------------------------------------------------------

and calling that gives the same exception, which is strange, as as manager 
it's ok.


Changing the line in ZPT pt_een from:
  <div tal:content="structure a/pt_twee">a/pt_twee</div>
to:
  <div tal:content="structure python: a.pt_twee()">a/pt_twee</div>

results in:
   Error Type: TALESError
   Error Value: exceptions.AttributeError on pt_twee
                in <PythonExpr a.pt_twee()>


So, what Martijn Faassen concluded (thanks for looking into it!):

  - when logged in as manager, Zope (correctly!) applies the acquired
    ZPT 'pt_twee' to the XML node;

  - when not, even with a proxy role, Zope (incorrectly!) tries to
    fetch the 'pt_twee' *index* of the XML node -
    getitem(a, 'pt_twee'); probably because of some security issue(?)


Could someone explain this, or confirm this is a bug?

Again, all files are accessible on my site mentioned above, in case you 
want to see the full traceback etc.

- Willem

Thanks Martijn. I hadn't considered using ParsedXML itself apart from
Zope. I'll mess with that a bit. Are there any other little sample programs
anywhere that use XBEL and the DOM?

Hi Tim,

You may need to use the python which came with your Zope, and add 
[pathToZope]/lib/python/ to your python path.  Then you should be able 
to use most anything which works from Zope in your Python programs.

Using it completely apart from Zope would be more difficult, as you
have some Zope dependencies (such as acquisition). But you're asking
on Zope-XML so I gave you a Zopeish answer. :)

I am not totally sure about the focus of this group. I apologize in
advance if this subject is inappropriate.

As for the subject:

This code works fine in the python (2.1.1) interpreter:

  from xml.dom import minidom

  myDoc = minidom.Document()
  myEl = myDoc.createElement('jeppe')
  myEl2 = myDoc.createElement('henning')
  myDoc.appendChild(myEl)
  myDoc.insertBefore(myEl2, myEl)
  print myEl2.parentNode
  print myEl2.nextSibling

  
However, when I put this code in a Zope (2.4.2) product, and run it, I get an
error on the last line:

  Error Type: AttributeError
  Error Value: nextSibling

with trace ending in:

  File /usr/lib/zope/lib/python/xml/dom/minidom.py, line 74, in __getattr__
  AttributeError: (see above)

  
So for some reason, the node myEl2 is not correctly inserted in the DOM.
It knows its parent, but not who is it's sibling. In fact, if nextSibling
were None, there wouldn't be an error, but now it doesn't even know it has
an attribute with this name.

Does anyone have an idea what could be the problem?

TIA,

Jesper

Anything about using XML in Zope is appropriate in my opinion. :)

This is the same interpreter as the one you use to run Zope?

I haven't used minidom, but if your Zope's Python is a different one than
the one you use on the commandline, it is possible the minidom in the
Zope install is perhaps an older version not yet supporting nextSibling?

Well, if it isn't that you're using a different version of minidom in
Zope I'm utterly clueless and it'd be a very weird problem; Python
code inside Zope ought to work exactly the same as Python code outside
Zope..

Ah, Martijn. I you were here I'd kiss your feet. This was indeed the
problem. The Python interpreter and Zope run the same code, but I had
forgotten to copy the minidom.py from the new Python version, and thus
I was running the older Python code without realizing it. Thank you! This
has been the most annoying bug I've experiencing in a long while.

Hi there,

NodePaths is now in ParsedXML CVS. I hope to do a new development release
of ParsedXML this week. NodePaths include:

  * new way to address nodes in documents using a special (funky looking)
    URL element like this: /child,0,3,4

  * Currently three ways to address nodes: 'child' (using child index),
    'element_id' (using unique element ids for elements, childs for the
    rest), and 'robust' (using heuristics)

  * Every element has a unique 'elementId' attribute. While this is
    guaranteed to be available and is always unique, particular element_ids
    will likely change each time you change a document and reparse it. (though
    not if you add nodes through the DOM, so it's more robust to changes
    than child indexes)

I've also made some progress on XMLWidgets, and I want to do a release of it (in
raw development form) soon as well. XMLWidgets allow you to attach 
methods to XML nodes based on what the node is or which node it is. So,
I can say 'all p nodes get this 'render' method, but all 'chapter' nodes get
this other 'render' method. This allows you to construct simple fairly
declarative renders of XML documents using the DOM. It also allows you to
construct more fancy things like authoring tools.

XMLWidgets plugs into the NodePath system of ParsedXML with its own
form of node paths, called 'widget'. They are very similar to 
element_id paths, with the difference that the object that will be returned
won't a be manageable node (node with manageable wrapper), but instead a
node with a widget wrapper (adding the methods to the node depending on the
association).

Think of this as a preview of some of the things Zope3 will be able to do,
though it'll likely be called entirely different things and work differently.
But conceptually there's some overlap. :)

Regards,

Martijn

Dear List,

is it possible to manipulate and extract node-Content of xml-Files just with the python that comes with zope 2.4.3 as it seems to me when I read Jesper Holmberg?s mail? Is there any documentation about it?

Anything about using XML in Zope is appropriate in my opinion. :)

Hi Elena,

I am by no means an expert in this field, and I'm sure you'll have answers
more knowledgeable than mine, but as far as my example, I have *not* just
used the basic functionality of Zope, but instead I have added necessary
Python libraries to my Zope installation to be able to work with XML.

Thus my example file starts with line:

from xml.dom import minidom

where minidom is not part of the standard Zope installation.

But as far as I understand it, the ParsedXML is a product which permits
you to work with XML under Zope.

Jesper

Elena,

It is possible to parse and manipulate XML using the standard python 
that comes with Zope.  Recent editions of Zope come with python 2.0, 
which includes several XML tools.  There are more advanced tools that 
you'll want if you get deeper into XML, but for basic stuff you should 
be fine with what's built in.

Here's a good starting point for the relevant documentation on built-in 
XML tools in Python 2.0:

http://www.python.org/doc/2.0/lib/markup.html

The Python XML Howto:

http://py-howto.sourceforge.net/xml-howto/xml-howto.html

How to write an application using the SAX interface:

http://www.hobby.nl/~scaprea/XML/

For further XML support, you'll want to install two libraries: PyXML and 
4Suite.  I'm afraid I'm not too knowledgeable about installing in 
windows, as I mainly use Linux and Mac, but they each include 
installation instructions and pre-compiled binaries are standard for 
windows, so it should be relatively easy.

PyXML (has a windows installer for Python 2.0):

http://sourceforge.net/projects/pyxml

4Suite installation instructions:

http://www.4suite.org/4Suite.org/documents/howto/4Suite/Windows

4Suite download (assuming you're using python 2.0):

ftp://ftp.fourthought.com/pub/4Suite/4Suite-0.11.1.win32-py2.0.exe

I hope this helps. If you have further questions, fire away!

Message-ID: <Pine.GSO.4.21.0112162200090.10732-100000@isis.visi.com>

Hi everyone,

I've been looking into ParsedXML a bit lately, and I wonder if someone more
experienced than I would be willing to offer a more specific example to get
me started. I feel like I'm really missing the big picture right now and I'm
hoping that having an example to work with will help.

Also, can anyone recommend some docs on the DOM for someone (me) that knows
a bit about XML basics, but am a complete newbie at programming with it.

I've got a sample bookmark file posted at
http://www.isd197.org/sibley/staff/wilsont/bookmarks.xml (24 kB) and I'd
like to render it like this:

Actual bookmarks should use the <title> to create a link to the
href. Folders should be a link to a new page that display whatever bookmarks
are present. I guess it's similar to a tree, but I don't want to use
<dtml-tree>

I'm having trouble figuring out what names to use to refer to all the nodes,
children, etc. The sample code that's included with ParsedXML might help
someone with more experience than I, but it hasn't done me much good yet.

Any hints (or sample code :-) would be greatly appreciated!

-Tim

Hi Tim,

The Python DOM Docs:

http://www.python.org/doc/current/lib/module-xml.dom.html

I tried to get to your example, but it required a login/password.

Unfortunately, most of the XML in Python documentation is focussed on 
SAX parsing, not DOM manipulations.  Here are a couple of starting 
points, though:

Python XML Howto:

http://py-howto.sourceforge.net/xml-howto/xml-howto.html

Python XML Topic Guide:

http://pyxml.sourceforge.net/topics/

Pyton XML Special Interest Group:

http://www.python.org/sigs/xml-sig/

If you post your example data and desired results (or a short form of 
each if they're long %-) I can take a stab at example code.

HTH

Hi Dethe,

Thanks for your willingness to look at my example. I've posted the bookmarks
file (right-click to download) and a simple mock-up at
http://www.isd197.org/sibley/staff/wilsont/xbel/ (Ignore the little
breadcrumbs menus at the top of the page.)

If I work on this some more, I'd probably add a little icon next to links to
subfolders to distinguish them from hyperlinks to other Web sites.

Hi Tim,

I'm going to be AWC (away from computer) for the rest of the day, so I 
won't be able to give you feedback until tonight or tomorrow, but wanted 
you to know the xbel file is still password-protected and I cannot

Try right-clicking on the link and saving to a file that way. It worked for
me.
