Subject: [XML-SIG] PyXML and DOM example 'generate_xml1.py'
Message-ID: <411464.18620.qm@web23704.mail.ird.yahoo.com>

I've started to use PyXML because I needed a xml library for a tool I am making. Due to lack of documentation, I have been looking for the examples, but I've found some of them does not work. In fact, the fist I tested was the one on the Subject. I have made some modifications get it to work. Here I paste the full file contents:



"""
A basic example of using the DOM to create an XML document from scratch.
"""


from xml.dom import ext
from xml.dom import implementation

if __name__ == '__main__':

    #Create a doctype using document type name, sysid and pubid
    dt = implementation.createDocumentType('mydoc', '', '')

    #Create a document using document element namespace URI, doc element
    #name and doctype.  This automatically creates a document element
    #which is the single element child of the document
    doc = implementation.

( None, 'mydoc', dt)

    #Get the document element
    doc_elem = doc.documentElement

    #Create an element: the Document instanmce acts as a factory
    new_elem = doc.createElementNS( None, 'spam')

    #Create an attribute on the new element
    new_elem.setAttributeNS( None, 'eggs', 'sunnysideup')

    #Create a text node
    new_text = doc.createTextNode('some text here...')

    #Add the new text node to the new element
    new_elem.appendChild(new_text)

    #Add the new element to the document element
    doc_elem.appendChild(new_elem)

    #Print out the resulting document
    import xml.dom.ext
    xml.dom.ext.Print(doc)



Basic changes have been: 

-Change createHTMLDocument for createDocument
-Change '' for None in, createDocument, createElementNS, createAttributeNS
-Change the two lines from "xml.doc.*" to "xml.dom.*"

Please, report if I am wrong or not.

Thanks,

David.

PS.- I have changed createHTMLDocument for createDocument because first only takes 2 arguments whereas second takes four, as it reported the function from inspect module 'getargspec'

if you're writing new code, I strongly suggest using a library based on 
the ElementTree API instead of struggling with an old, unmaintained and 
rather unwieldy XML library.

if I'm reading things correctly, your entire example boils down to

     import xml.etree.ElementTree as ET

     elem = ET.Element("spam", eggs="sunny side up")
     elem.text = "some text here..."

     print ET.tostring(elem)

with the ET API.

The standard implementation of ET is included in Python 2.5 and later:

    http://docs.python.org/dev/library/xml.etree.elementtree.html

and is available for Python 1.5.2 and newer from here:

    http://effbot.org/zone/element-index.htm

and there's also a separate implementation based on the libxml2 and 
libxslt libraries, which adds validation and lots of other goodies:

Hallo,
 I have Python 2.5 version on a MacOSX, and tried to install Pyxml:
python setup.py build

error: command 'gcc' failed with exit status 1

I previously had problems with other programs I tried to install, as if no
gcc compiler could be found, but do not know how to check that indeed ( I
used alternative programs previously).
Could you please help me with that? I am a newbie in such issues...
Thank you in advance,

I do not know MacOSX (I use only free software) but isn't there a
packaging system with already-made Pyxml packages?

Compiling by yourself (if you are not a developer) is quite 20th
century :-)

gcc is included in the Apple developer toolset known as Xcode.  Xcode  
is available as a free download from http://developer.apple.com/

Subject: [XML-SIG] Choosing an XML method for a backing store
Message-ID: <e17d46420809211157v625b98d4j1f463c1b5e7f70c@mail.gmail.com>

I'm writing a simple application that has a tree-like data structure.
I'd like to be able to eventually easily synchronize this data from
one client to another.  With that in mind, I have a few questions
regarding how I should best store my data and whether DOM or SAX is a
more appropriate choice.  I am new to XML and am trying to make sure
I'm headed in the right direction before I make any pervasive changes
to my application.  If I'm barking up the wrong tree, can someone
point me in the right direction?

Example data structure

list of type A
  type A
    data
  type A
    data

tree of types B,C,D,E
type B
  data
  list of type C
    type C
      data
      type B ref
      list of type D
        type D
          data
          type C ref
          list of type E
            data
            type D ref
            list of type A ref
              type A ref
              type A ref

Thoughts/Questions:
1) The structure seems to lend itself well to DOM

2) Using DOM seems to mean one single file, which makes synchonization
harder and more error prone, lots of individual files seem like a
better approach for that

3) Since I already have a data structure, it seems I'd end up building
the DOM, then constructing the data structure from the DOM, then
writing the entire thing out on each save... seems to invalidate some
of the benefits of a DOM (easy reorganization of nodes for example).

4) Is it common practice to subclass the DOM objects into something my
application can use explicitly, thus avoiding the need to convert from
the DOM to the structure outlined above?  My objects currently use
signals to communication with the GUI and other objects.

5) Is there a common practice for dealing with the references in my
data structure?  For example, when parsing the XML file(s) with SAX it
is possible I'll come across a reference to an object that hasn't yet
been created and is defined elsewhere in the file (or another file).
My thought was to store a unique ID for each object, and use object
reference elements in the xml with the unique as CTEXT, if this is
encountered and the object hasn't been constructed, a proxy object
would be built and converted to a complete object when the xml data
for it was encountered.

Thanks for the time,
