Large XML files

I am testing the possibilities of delivering the content of XML Documents through the Zope environment. Unfortunately, some of the proposed file are rather large (up to 760KB) and just uploading them and viewing them on our current Zope server is prohibitively slow. Our server, running Z2 is a blazing P133 running NT 4.0 with 32 MB of RAM (I get the bottom feeders). Is the bottleneck the hardware; is there something I can do software-wise to improve performance; or is development not yet advanced enough to handle this scenario efficiently? Any opinions on this? Thanks, P. Johnson

RE: [Zope] FTP in HTML-Kit? Sussed it!
by Paul Browning 06 Dec '00

06 Dec '00

Like others I was a bit puzzled as to how to Save As FTP in HTML-Kit. I've just downloaded build 290 and got it all working (the stuff may have lain undiscovered in earlier verions - RTFM .....). The keys to cracking it are: 1. Go Workspace -> Add FTP Server/Folder -> Add FTP Server. Do the obvious (all familiar to Homesite users). A blue coloured ftp source will appear in the File pane on the RHS. Expand/collapse trees to navigate to the file you want to open. 2. Right-click and "Open As Text". Haven't yet fathomed the significance of this as opposed to other options. What I do know is that "Save" then does the business - saves it back to your FTP source. As a 24-day-old (6 days to go ....) Homesite evaluation user I'm really, really impressed so far with HTML-Kit. My thanks to Phil Harris et al for the tip.

META Tags in Zope Documents
by David Legg 06 Dec '00

06 Dec '00

Hello, I am currently embedding meta tags into documents within the Zope environment. At the moment the meta tags are in the standard_html_header file and embedded within index_html and other documents. Are there any issues with embedding meta data this way when a search engine spiders the site? Will the search engine pick up the contents of <dtml-var standard_html_header> or just the literal document itself, or is there anything else to consider? Thanks in advance, David

RE: [Zope] string splitting in dtml

You're right, it's not really a string, even though Zope is smart enough to render it into one when inserting it directly into HTML. > I also tried the > > <dtml-var "_.string.split(start_date, '/')[1]"> > > solution but got the error: > > Error Type: TypeError > Error Value: argument 1: expected read-only character buffer, instance found Now if only Zope were smart enough to tel us what it "really" is, so we could transform it! It looks like MS Access delivers dates as some proprietary object type. However, in your query, you may be able to wrap the date field like so: to_char(dateFieldName) to convince MS Access to return a formatted string instead. Once you can see what the string looks like, the slicing bit should work. Good Luck! Jerry S.

New user - couple of questions
by Paolo Quaglia 06 Dec '00

06 Dec '00

Hi to all, I'm a new Zope user/developer ... Zope has impressed me very much! Ihave a couple of questions. I want to build a new intranet site for my company using Zope, but: 1. How can I import and use Python modules For example I want to use the function sleep(secs) that resides in the time module. I wrote this code: import time def hello(self): sleep(10) return "I'm Back!!" but when I call the external method bounded with the hello function an error occours!! 1st. Have I to install the time module? - if yes where can I found it and where can I install it? 2nd. How do I have to call the sleep function? 2. I want to build an application that use the database transection to update rows. I use SQL server that support DB transactions. where can I build SQL transactions with Zope? do I have to build a ZSQL method with multiple SQL calls? .. for example: ... begin transaction <dtml-var sql_delimiter> update t_cliente set primaetichinterna = 'mia' <dtml-var sql_delimiter> commit .... Am I sure that the transaction will work (if another user use the same method at the same time)? How can I test if a transaction has been committed or aborted? Thanks VERY MUCH in advance Paolo Quaglia Sitek Spa Italy Paolo Quaglia Information Technology Coordinator Sitek S.p.A. paolo(a)sitek.it

Hallo, I've got a minor problem. My ZClasses won't update the ClassIcons when I change them. Has someone implemented an aesthetic-filter? A great step in AI?? Furthermore a nice St.Nikolaus, like we say in Germany.

From: Mark A. Pappas [mailto:pappasm@ashecca.com] >after the -D. In the start.bat. I tried all kinds of things and never was >able to get zope up on port 80 as a web server (www.whatever.com_ or >XXX.XXX.XXX.XXX). What am I missing? Your approach sound about right. Perhaps you are running another webserver at port 80? Have you got Apache or IIS running on your machine allready, chances are that they are using port 80 allready creating a conflict. Regards Max M
