OpenOffice files are merely zip files with well documented XML inside. Use the builtin zip module to open them, and then it's just XML parsing. As far as the editor, you'll have to familiarize yourself with the XML data from the documentation, and it sounds like that's quite a project. it is indeed a huge project but I need to get started. I know that it is xml inside a zipped archive. but reading the documents is one thing and rendering them is another. just in case we can convert it to html and then render it in some kind of a html browser or html text area and then when user makes changes to the document, we can save it back to odt. but for that we need both way conversion. Just out of curiosity, why not just download OpenOffice? I wished I could use it out of the box. but the problem is that open office does not provide any accessibility on windows and on linux the work is going on. regards.

help developing an editor to view openoffice files.
hello, right now I am involved on doing a very important accessibility work. as many people may or may not know that I am a visually handicap person and work a lot on accessibility. the main issue at hand is to create an accessible editor for open office. there are a lot of things remaining on that front. so right now I am trying to find out a temporary work around by creating a simple accessible editor (with wxpython) for viewing and editing open office files. I know there must be python libraries that can open/ save .odt files because it is an open standard any ways. but I am trying to work out a kind of a program where those files can also be displayed in a text area with all the formatting. probably one way of doing it is to use some thing like a rich text editor and allow the file to be converted to rtf from odt for viewing and back again to odt when the user wishes to save it. another way I find is to actually find out if there is a odt text box that can display these files as they are. viewing the contents of the files in an editable way is most important. any suggestions? regards.

Krishnakant. There is an O'Reilly Book about hacking the Open Office Format, and it is available free on line in both html and pdf. Open office files are a variation on 'Zipped' archives and many unzip tools can be used to open them, apart from ones that insist on a .zip extension. These include python tools. The one 'case study' in the book that uses python is actually for a spreadsheet, but that makes little difference to the 'unzipping' part. You can find it at: http://books.evc-cit.info/odbook/ch05.html#modify-spreadsheet-section Once you have the raw XML you should be able to convert it to any one of many more accessible XML formats, for screen readers, brail printers and so on. I don't know much about them, but hopefully you do! Don't re-invent the wheel! You will find quite a few ways on the Open Office Wiki for converting the format to other things. You can also daisy-tail the XSLT files; for example use one to convert to xhtml and a second that converts xhtml to text. Example (Display write files in the 'Firefox' browser). http://wiki.services.openoffice.org/wiki/Firefox_ODFReader_extension Don't forget that Open Office already has PDF export facilities, and Acrobat reader already has some accessibility ability for simple documents (i.e single column, 'start at the beginning, keep going until you get to the end, and then stop'). For adding structure to other PDF files you would need Acrobat Professional or software that can export 'tagged' PDFs. The case-study code is: import xml.dom import xml.dom.ext import xml.dom.minidom import xml.parsers.expat import sys import od_number from zipfile import * from StringIO import * if (len(sys.argv) == 4): # Open an existing OpenDocument file # inFile = ZipFile( sys.argv[1] ) # ...and a brand new output file # outFile = ZipFile( sys.argv[2], w, ZIP_DEFLATED ); getParameters( sys.argv[3] ) # # modify all appropriate currency styles # fixCurrency( styles.xml ) fixCurrency( content.xml ) # # copy the manifest # copyManifest( ) inFile.close outFile.close else: print Usage: + sys.argv[0] + inputfile outputfile parameterfile -- http://mail.python.org/mailman/listinfo/python-list

Re: help developing an editor to view openoffice files.
hello, well what I exactly need to do is firstly have a way to read .odt and .ods files. I have a lot of information in open office format which I need to access. The most important thing is that I completely want to avoid the use of microsoft office. so I need to firstly get access to open office documents through a python module that can read and parse those documents and may be convert it to html and display in some kind of an html/ text area may be wxpython can help? secondly I want to edit those documents may be in html format and then when I say sayve it should save the changes back to .odt with the formatting information. can this be made possible? thanks and regards, Krishnakant. -- http://mail.python.org/mailman/listinfo/python-list
