You can edit the XML, then transform it and run it in a browser to see how it looks. Works great. For production I run the stylesheet using batch files. One advantage of using XML it that you can make the structure much simpler (than HTML), so editing it by hand is often pretty easy. >Is there some demo online where it is possible to edit a XML document, >modify/add/delete nodes? >(I used the sax python library to do it, but without XSL/CSS the document >looks ugly) > There are a lot of editors and editor demos out there, but most of the ones I have tried aren't too useful. One that is useful is XED at http://www.ltg.ed.ac.uk/~ht/xed.html Works very nicely but only on Windows and Solaris. >The only library I found for XSL and python is 'xslpattern', has anybody >used it? > 4XSLT is available and pretty well up to date with the standards. Trouble is, so far it's only working on unix/linux - they have to compile some C code and link it in, I think - and there are a lot of parts to install to get it working right. But it might work fine for you: http://opentechnology.org/4Suite/4XSLT/ The XML editors mostly can't display styled XML documents. The InDelv browser will, but last time I tried to use it it wasn't practical because you couldn't troubleshoot stylesheets and it was written to an old XSL draft. They did say they will be fixing these problems, though: http://www.indelv.com/client.htm The browser part is free even though it comes with a demo version of a non-free editor (which I haven't tried). If they get it fully working it should be a great tool. It's Java, so should run most places.

Well, it was destined to happen - and so it did. Using Squishdot, I've managed to hit the 2gb filesize limitation of Linux ext2. The squishdot posts were automated to grab headlines from other sites. Over the past month or so, this has grown very quickly. I've fought with Reiserfs in the past (only to have the entire filesystem corrupt itself beyond repair due to large file limitation). I'm hesitant to fire up the beta iterations of ext3, and xfs isn't due out anytime soon. Argh. Without breaking up the ZODB store into smaller substores, I'm left with the task of making a Linux filesystem that can exceed the 2gb file limit (or patch my kernel to use the ext2 file limit hack). Any suggestions? - Ian C. Blenke <ian(a)blenke.com> <icblenke(a)2c2.com>

Those are external methods. >In the cases of the Z Classes, they are members of the class. Vanilla Zope >objects like DTML Documents are acquiring those methods from a parent >folder. Hmmm, I don't quite understand. Are you saying that ya'll created and placed in the root folder, say, an external method named 'date' that does the equivalent of the following in a DTML Method <dtml-return bobobase_modification_time> And then you added a field called 'date' to the ZCatalog metadata and index tabs? This seems to work here with a DTML Method -- why was an external method necessary? Also doesn't this mean that the ZCatalog instance is duplicating data, storing the date under both the 'bobobase_modification_time' (for backward compatibility) and 'date' columns? This seems like a bit of overhead just to be able to use the shorter name in search DTML, or am I missing the benefit/intent? {also to construct the 'url' attribute, how did you obtain the url of an arbitrary object -- the generic Zope equivalent of "getpath(record_id)"?} -Jeff Rush

Auction Components

Hello Again, Does anyone know of any auction extensions for Zope? Is anyone working on one? I have a need for some basic functionality and will develop it myself but I do not want to reinvent the wheel if someone else has or is already developing one.

MySQL problem with Zope 2.01 on Linux RH 6.0
by Andreas Björck 03 Nov '99

03 Nov '99

Hello, I've followed the instructions as described in http://www.zope.org/Members/alanpog/zmysqlda_steps but I can't get the MySQLdb-0.1.0 to install. The system is a Linux RH 6.0 Kernel 2.2.5-15 and I have installed MySQL 3.22.27 from source, Python 1.5.2 from source, Zope 2.01 from source. The error I get when trying the "python build.py" as described in the MySQLdb-0.1.0 README.txt file, is something like this: [snippet...] make -f Makefile do-it-again make[2]: Entering directory `/usr/local/Zope-2.0.1-linux2-x86/lib/python/Products/MySQLdb-0.1.0' /usr/lib/python1.5/config/makesetup \ -m Makefile.pre -c /usr/lib/python1.5/config/config.c.in Setup -n /usr/lib/python1.5/config/Setup make[2]: Leaving directory `/usr/local/Zope-2.0.1-linux2-x86/lib/python/Products/MySQLdb-0.1.0' make[1]: Leaving directory `/usr/local/Zope-2.0.1-linux2-x86/lib/python/Products/MySQLdb-0.1.0' gcc -fPIC -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5 -DHAVE_CONFIG_H -I/usr/include/mysql -c ./_mysqlmodule.c ./_mysqlmodule.c: In function `_mysql_ConnectionObject_affected_rows': ./_mysqlmodule.c:478: warning: return makes pointer from integer without a cast ./_mysqlmodule.c: In function `_mysql_ConnectionObject_insert_id': ./_mysqlmodule.c:817: warning: return makes pointer from integer without a cast ./_mysqlmodule.c: In function `_mysql_ResultObject_num_rows': ./_mysqlmodule.c:924: warning: return makes pointer from integer without a cast ./_mysqlmodule.c: In function `init_mysql': ./_mysqlmodule.c:1366: warning: assignment makes pointer from integer without a cast gcc -shared _mysqlmodule.o -L/usr/lib/mysql -lmysqlclient -o _mysqlmodule.so Traceback (innermost last): File "build.py", line 14, in ? import MySQLdb File "MySQLdb.py", line 19, in ? from _mysql import * ImportError: libmysqlclient.so.6: cannot open shared object file: No such file or directory [...snippet] The libmysqlclient.so.6 exists in /usr/lib/mysql/, so I guess that can't be the error. After that I figured I'd attempt installing the ZMySQLDA-1.1.3, but I understand I need to install the MySQLdb module first. MySQL is a pretty popular database, so I hope someone has run into this as well, and hopefully solved the problem. Regards, Andreas

Z39.50
by Fredrick Rybarczyk 03 Nov '99

03 Nov '99

We are using Z39.50 in lots of projects and it would be really cool to use Zope as a gateway for it. We would have to create a product that configures the mappings between a webform and Z39.50 server profiles. ..and some other stuff as well.. I suggest that we discuss this privately.. ..if anyone is intrested that is.
