ParsedXML
by Einar Næss Jensen 13 Nov '02

13 Nov '02

Two questions concerning two different products. 1: ParsedXML I have tried to install ParsedXML with zope 2.51 on redhat 7.2. This is what i get: 2002-11-13T13:46:00 ERROR(200) Zope Couldn't install ParsedXML Traceback (innermost last): File /home/zope/lib/python/OFS/Application.py, line 637, in install_product (Object: Zope) (Info: ParsedXML) File /home/zope/lib/python/Products/ParsedXML/__init__.py, line 92, in initialize AttributeError: 'Products.ParsedXML.ParsedXML' module has no attribute 'ParsedXML' I am no python guru. this does not tell me much. the __init__.py looks like this: def initialize(context): import ParsedXML context.registerClass( ParsedXML.ParsedXML, permission = 'Add Documents, Images, and Files', icon='www/pxml.gif', constructors = (ParsedXML.manage_addParsedXMLForm, ParsedXML.manage_addParsedXML) ) context.registerHelp() context.registerHelpTitle('Parsed XML Help') #context.registerHelpTopic('ParsedXML_Edit', ParsedXML_Edit()) My second problem is this: the product XMLTransform seems to install just fine, but when I try to add a Transformer registry, i get the errormessage "global name 'mesage' is not defined." What happened? What did I do wrong?? I will appreciate any suggestions to what I may do. Also: Is there a preffered method to extract elements from XML-documents and transform them into html?

Delayed full-text indexing for huge documents
by Thierry Florac 13 Nov '02

13 Nov '02

Hi, I'm actually building a Zope intranet documentation web site storing many documents ; all the documents are indexed in a ZCatalog for several metadatas as well as for the "full-text" indexing (using TextIndexNG product). Some of these documents are quite huge, so indexing them can take a lot of time. What I'd like to do is : - index common metadatas as soon as a document is published (mandatory to my site browsing) - update "full-text" index in a daily batch (as long as retrieving these documents does not need to be immediate) A solution I currently use to handle this was to create two ZCatalogs, one for the common metadatas and another one for full-text index. This works quite well, but makes ZCatalog queries more complex when I have to mix indexes. Is there any good solution to handle this kind of problem ?? Many thanks, Thierry -- Linux every day, keeps Dr Watson away... http://gpc.sourceforge.net -- http://www.ulthar.net

Newbie question - blob fields
by Ashley Lloyd 13 Nov '02

13 Nov '02

Can anoyone answer this? I know I posted the other day, and I'm sorry for re-posting, but if anyone can help I'd be very grateful! Thanks ------------------------------------------------------------------- I am quite new to Zope, and I am attempting to implement a Zope application connecting to an existing Interbase database (using Kinterbasdb). I don't seem to have many problems, but do have one with a BLOB field in the database (subtype text). Reading from it is not a problem, but attempting to write to it I get an error (-413, 'execute.isc_dsql_execute: conversion error from string "BLOB". '). I have tried various changes to the type of the input field, and to the insert SQL, but I've had no luck. I have read various postings here and there with similar questions. I seem to get the idea that I can't do this. Can anyone confirm this or preferably explain how wrong I am and why! Thanks in advance, Ashley _________________________________________________________________ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail

Problem with a value assigned in a session mysteriously being overwritten by 0
by Charlie Clark 13 Nov '02

13 Nov '02

Hi, I'm currently using Zope 2.5.1 and have recently discovered a really nasty problem which I cannot explain and am having great difficulty finding a workaround. I have a log-in process with several forms and I use a session object to keep some data (ie. foreign keys) between forms. This has so far worked very well but now one of the values is being overwritten by 0. I can tell when this is happening but can't work out why. Brief description of what's happening: 1st form -> PythonScript: generate 'id_person' do some database work, assign session['id_person'] = id_person, assign session['username'] = username -> call 2nd form via request.response.redirect 2nd form -> PythonScript: do some more work dependent on the key 'id_person' Observations: The 'id_person' is still visible in the session object in the 2nd form but has been assigned to 0 by the PythonScript. But it is the only session variable which has been overwritten. I can't think how this would affect things but I have changed some calls from context.Objectname(request, context) to request.response('Objectname'). Any ideas? The only current workaround I can think of is to pass the key as a hidden value through the form but I'd like to avoid that if possible. Charlie

How to check for valid HTML?
by Martin Kieferhagen 13 Nov '02

13 Nov '02

Hi, Is there a way to check (in a Python script) if a given string is valid HTML code? Ideally, it should return some useful error message (e.g. what you get from the TTW) if the code is not valid HTML. And: Does already some sort of "html_unqoute()" (reversing the effect of html_qoute()) exist in Zope? Thanks, -- Martin This eMail was sent to you using the latest weapon in the war against SPAM.

Authenticate users using a already defined Mysql-Database
by andy toenz 13 Nov '02

13 Nov '02

Hi, wanna migrate my web-project from an proprietary sql-based solution to a zope-project, because I see many benefits and pro's from zope. But I've the problem that I have to migrate about 200 users from my SQL-Database into Zope. I've seen projects like mysqlUserFolders but these have another table-structure. So my question: Is there an easy way to authenticate via Zope using my own database/tables ? table users; | uid | username | password | surname | firstname | This means, that Zope gets the username from that table and authenticates it using the password in this table. It's a bad idea to change the current database-structure, because there exist many foreign-keys that refers to 'uid' etc. Any ideas ? ________________________________________________________________ Viren?

iterating dicts in dtml
by Jorg E. Rødsjø 13 Nov '02

13 Nov '02

The function makePhoneList returns a list of dictionaries. Iterating over the list is ok, but I am having problems doing the same over the dictionaries. This is my idea, which does not seem to be the right one:) <dtml-in "makePhoneList(searchString='foo')"> <dtml-in sequence-item mapping> <dtml-var 'bar'> # Where 'bar' is a key in the dictionary. </dtml-in> </dtml-in> anyone?
