Parsing XML into/out of the database
by Tony McDonald 18 Mar '99

18 Mar '99

Hi all, I have an application that consists of 140+ XML documents, roughly 100k bytes each that I want to be able to query (using XSL pattern matching at present) and output to XML/HTML and RTF format. This will happen in real time (if at all possible). At the moment, my XML documents are held as files in a real file system (sacrilige! :). However, I'd like to get them into the database structure if at all possible, as I imagine it will make things easier in terms of searching. For example, the XML file <?xml version="1.0"?> <document title="Cell Biology"> <topic title="introduction" id="cb1"> Cell Biology is a good thing. If it weren't for Cell Biology, you wouldn't be around. </topic> <topic title="lectures" id="cb2"> <topic title="lecture" id="cb2" num="1"> This is lecture 1. </topic> <topic title="lecture" id="cb3" num="2"> This is lecture 2. </topic> <topic title="reading list" id="cb4"> <topic title="bok" id="cb5"> A big bok </topic> </topic> </topic> Would lend itself to creation in the Zope database really easily (I think). XML elements (document, topic) and attributes such as id (used to uniquely identify an element) and title would be properties of the DTML document/method. So long as the id numbers were properly arranged, it should be *relatively* (good word that!) simple to recreate the original XML document. I assume that parsing the XML (in actual fact, the DTML doc/method would consist of *very little* XML I think, it all being taken care of in properties) to create HTML would be, again, relatively easy (my own tendency is to use the 'title' attribute as a class identifier for cascading style sheets). My question is, do people think that this idea could fly? I have spent *a long time* looking at how to get our Word (sorry for saying that!) documents into a format that means they can be easily put into a database and thereby benefit from all the good things that means. Several cul-de-sacs and wasted weekends later, it seems to me that Zope is coming out to be the closest thing to a solution for my problem... (I know from off-list discussions that there's a definite 'weirdness' about how people have been wanting/needing to implement things and then finding that (a) Zope does it already, (b) there's a product available or (c) someones working on it... !). any thoughts, as usual, greatly appreciated. tone.

Newbie: How to make Apache Play Nice...
by Christopher.Abraham＠cio.treas.gov 18 Mar '99

18 Mar '99

Hi. Here's the required History: Cold Fusion almost then found PHP3 and now ZOPE. I am running a P100 RH5.2 Apache 1.3, Kernel 2.0.36 and I am pretty sure I have Zope running: http://memes.org But neither my guru or I can get Apache to dance with Zope -- I am having all kinds of problems getting the admin page to work with me and my Login/PW is just not taking. My guru cannot even get it going and suggests using the Python server -- but I shall not be dashed -- any more info you need, I will give you a wee bit more: Want to use MySQL and will be developing a Writer's site -- for my fun and no profit, currently at: http://coelaboration.com -- I want to publish Hyperfiction and Hypertext using Zope as opposed to Perl or flatstatic... Cheers in advance... Chris

Re: [Zope] Newbie install help needed !!!!!

Hope you don't mind me butting in, but if you just want to check out Zope very quickly, run the Windows version on 95/98/NT. It was nothing to install, and I was playing with Zope two minutes after downloading it. Python is also a snap to insall on Windows. -----Original Message----- From: Thomas Schruefer <tschruefer(a)mail.howard.k12.md.us> To: Zope <zope(a)zope.org> Date: Thursday, March 18, 1999 10:09 AM Subject: Re: [Zope] Newbie install help needed !!!!! > > >>Robert OConnor - rocon(a)pivot.net on 3/18/99 8:13 AM wrote: > >>Hi Thomas, >> > >>***This is were you got stuck*** >> >>./install >> >>***No switches!!! >> > >Ok, unstuck, whoops, stuck again. > >I guess I have to do this in little baby steps.

I guess I have to do this in little baby steps. Some sort of initiation ritual, I think. ;-) Now I am getting the error message below even though python is clearly in the bin directory under the Zope install directory. "./install: bin/python: No such file or directory" This is the shell install script: *** #!/bin/sh # Get script dir if [ -n "`echo $0|sed -e 's%[^/]%%'`" ]; then PYTHONHOME=`echo $0 | sed -e 's%/[a-z.]*$%%'` cd $PYTHONHOME else PYTHONHOME=. fi export PYTHONHOME bin/python inst/product_install.py $* *** A little different than the PERL I am used to seeing, but I've managed to make heads-and-tails of the thing. - I checked the location of python in the Zope install dir, ok. - I checked to ensure that the sh shell was in the bin/ dir, ok. Next up, re-upload the Zope file and check for a corrupted archive. Any other ideas ?

Hi Thomas, >Is there anyone that could help or give me some pointers ? Yup, those switch options are confusing so I avoid them ;-) First, the most helpful tool for me in working with Linux is "git". This is a nice character based navigation and file management utility. Just type git. It came on my RH Linux and is installed automatically without your request. This program is alot like the DOS Norton Commander that I started using years ago. So you get the distribution: Zope-1_10_2-linux2-x86.tgz I use git's F6 key to rename it zope1102.tgz to ease the long typing. Move it to a newly created directory (F7) named perhaps "zope". Then in that directory, type: tar -xvzf zope1102.tgz A new directory is then created under your new zope directory named: Zope-1_10_2-linux2-x86.tgz/ Go into this directory and type ***This is were you got stuck*** ./install ***No switches!!! Then edit the access file now in this directory and change the obscure username and password to your favorites with F4 key to use "vi" Press i to insert new user/passwrd -- example: zope:gogo Press escape then :wq to save. Then ./start to start zope and maybe later if you EVER want to stop zope (who would ever WANT to stop!, ./stop. BTW, if you want to test the integrity of the downloaded zope distro, only change the t to an x as in: tar -xvzf zope1102.tgz Enjoy!!! -bobo connor

Python freezes in lwp_sema_p()
by Andreas Jung 18 Mar '99

18 Mar '99

We are running Python1.5.2b2 (with thread support) , latest DCOracle, Oracle 7.3 under Solaris 2.5.1. Some of our applications hang in about 10% when they run. We trussed the binaries and discovered that they all sleep in a lwp_sema_p() call. Python/thread_cthread.h seems to mention a problem with the Solaris PThreads implementation however I can't figure out if this is the real problem. I am not sure whether it's a problem of Python, DCOracle or the Oracle libraries. Any ideas or comments ?

Zope LDAP Products available (v0.1)
by Anthony Baxter 18 Mar '99

18 Mar '99

Short Version of message: ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now available from http://www.interlink.com.au/anthony/python/ I'm looking for opinions on the LDAP zope product I've been building. Right now, LDAP connections work, LDAP Methods work, but there's still a bit more to do. Right now, the following is unimplemented: In ZLDAPconn: . Anything other than simple_bind(who, passwd) for connecting to the LDAP server . meaningful doc strings In ZLDAPMethods: . Pluggable Brains . Result Caching . Limits on the number of results . Variable interpolation in the filters, and in the base DN . modify or add queries (only search is supported right now) . meaningful doc strings :) Other stuff: . UserLDAP is not finished yet (or released) - the primary issue is the storing of roles and domains. Right now this would have to be some non-standard LDAP attribute... but what should it be? It also probably needs modify and add added to ZLDAPMethods before being really useful. Things I'd like comments on: For ZLDAPconn: what other bind methods would you like to see? For ZLDAPMethods: how should add/modify/query be distinguished? Separate methods? I had planned to get variable interpolation working tonight, but decided I'd rather get an early night. Probably tomorrow evening, instead. Stuff I hope to get going in the next day or so: variable interpolation, pluggable brains. Anyway, ZLDAPconn-0.1 and ZLDAPMethods-0.1 are now available from http://www.interlink.com.au/anthony/python/ It requires David Leonard's ldapmodule, from http://www.it.uq.edu.au/personal/leonard/dc-prj/ldapmodule/ It's been tested on Linux 2.2, under Zope 1.10.2 and ZServer. Assuming the ldapmodule works on other platforms (it's available in source, and also as a windows .pyd) it should work elsewhere, too. Anthony

ZAP
by Shaw, Howard 18 Mar '99

18 Mar '99

How can I configure ZAP so that all http requests go through the cgi? Zope is the only thing running through this apache, so I don't want everything on the site prefixed with Zope/ (or anything else, so no, I don't just want to know how to change the prefix). This is basically what is keeping me on ZopeHTTPServer. BTW, running ZopeHTTPServer multi-threaded worked well for about 15 minutes. Then suddenly certain pages wouldn't load. I stopped and restarted the server, but the pages still wouldn't load. I also noticed that if I stopped Netscape and hit reload, it would cause several new ZopeHTTPServer instances to appear, and doing so again would continue to create new instances which never seemed to dissappear. Are these locking the items they are downloading? The behavior I saw seemed consonant with it locking the item it was downloading, then failing to recognize the netscape had disconnected, and thus never removed its lock. When I restarted it single-threaded, all the pages came up without a problem. I would really like to move to Zap, but I can't afford at this point to have the URL of the page change. How can I make a Zope pcgi accessible as the root of a Zap install? Please help. Howard C. Shaw III Programmer/SysAdmin St. Thomas High School

multiple trees
by cimarron＠taylors.org 18 Mar '99

18 Mar '99

There seems to be a problem with DTML documents which uses more than one  ..  sections. I'm seeing a python error when attempting to expand any node of the second tree. I'm going to try and fix this on my own as a way to familiarize myself with Zope internals but I thought others on this list might want to be aware of the problem and/or provide information about their own experience with multiple trees.
