Python Script limit in range()
by Peter Bengtsson 14 Mar '01

14 Mar '01

A simple Script (Python) of mine: Id: randomtext_pys Title: Returns a random text <params>length=500</params> [code] import string import random text='' pool = "qwertyuioplkjhgfdsazxcvbnm 1234567890 \n" for i in range(int(length)): text='%s%s'%(text,pool[random.randint(0,(len(pool)-1))]) return text [/code] When I test this script within the management interface of Python Scripts everything looks good and I can enter values of "length" like 100 to 10 000. However, when I call this script from a DTML Method like this: <dtml-var "randomtext_pys(1000)"> it throws an error at me. <dtml-var "randomgtext_pys(500)"> and <dtml-var "randomgtext_pys(999)"> works fine. Error Type: ValueError Error Value: range() too large (traceback below) So according to the traceback the error you find this: ----------- lib/python/DocumentTemplate/DT_Util.py ------------ def careful_range(md, iFirst, *args): # limited range function from Martijn Pieters RANGELIMIT = 1000 if not len(args): iStart, iEnd, iStep = 0, iFirst, 1 elif len(args) == 1: iStart, iEnd, iStep = iFirst, args[0], 1 elif len(args) == 2: iStart, iEnd, iStep = iFirst, args[0], args[1] else: raise AttributeError, 'range() requires 1-3 int arguments' if iStep == 0: raise ValueError, 'zero step for range()' iLen = int((iEnd - iStart) / iStep) if iLen < 0: iLen = 0 if iLen >= RANGELIMIT: raise ValueError, 'range() too large' return range(iStart, iEnd, iStep) ------------------------------------------------------------------- WHY is that LIMIT there? I can mod my Python Script to accomodate for the value of 1000, but I am just curious of it.

XML Parsed for all platforms?
by Zanotti Michele 14 Mar '01

Ciao, I see that XMLParsed 0.1 b3 is only for generic Unix-like platform, while 0.1 b1 and b2 are for all platforms. Do you know if XMLParsed developers want to abandon Win platform?

It'll let you access your XML via DOM calls. They may seem less convenient than your example, but will cover the cases where you have more than one 'comic' element. Your example could translate to: xmlDoc.documentElement.childNodes[0].childNodes[0].childNodes[0] xmlDoc.documentElement.childNodes[0].getAttribute('issue') or by using the tagname the first example would become: comic = xmlDoc.documentElement.getElementsByTagName('comic')[0] authorName = comic.getElementsByTagName('author')[0].getChildNodes(0) In future versions, XML id support is planned; if you have a DTD that tells the parser what attributes are Id's, you can traverse the tree using Id attributes for the same effect. Then you can use a document like: <collection> <comic issue="1" id="first_issue"> <author>Stan Lee</author> </comic> </collection> and code like: comic = xmlDoc.getElementById('first_issue') authorName = comic.getElementsByTagName('author')[0].getChildNodes(0) Hope this helps! -- Martijn Pieters | Software Engineer mailto:mj@digicool.com | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ --------------------------------------------- _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Natural XML Parsing
by Jeff Griffith 14 Mar '01

14 Mar '01

Hey All, While messing around with XML I became really frustrated at how unnatural it seemed to extract data out of documents. I ended up writing my own python class to do exactly what felt natural. The problem is the entire time I kept telling myself "this code has to already exist somewhere" I just could never find it. So if anyone is interested take a look at how this class works and tell me if 1) this seems useful 2) this is already supported by someone else A brief example of how it is used -------------- < collection > < comic issue="1"> < author > Stan Lee < /author > < /comic > < /collection > can be accessed as collection.comic.author.TEXT collection.comic.ATTR('issue') --------------- a more complete write-up w/source is available at http://www.people.hbs.edu/jgriffith/simplexmlobject.html Thanks! -Jeff Griffith

Re: [Zope] ZSQL method LAST_INSERT_ID() error
by paul_s_johnson＠urscorp.com 14 Mar '01

14 Mar '01

Thanks for the all tips; it's getting me down the right road. I also learned I need to include my LAST_INSERT_ID in the same ZSQL method as my INSERT statement and join them together with a <dtml-var sql_delimiter> inside the method. That said, it's still not working. Here's what's returned when I test my method: There was no data matching this sql_add_deliverable query. SQL used: INSERT INTO Deliverables ( DeliverableID, ProjectID, DeliverableTypeID, UserID, Abstract, DateEntered, CategoryRequest) VALUES ( NULL, 1, 2, 3, 'some text blah blah', NOW(), '5') ------------------------------------------------------------ SELECT LAST_INSERT_ID() AS TheLastID The INSERT part of the above works and inserts the data into the table. The DeliverableID field of the Deliverables table is really an AUTO_INCREMENT field. I tested the above at the MySQL command line and the LAST_INSERT_ID () function returns the correct ID. Why is no data returned? I should be getting the last ID and I'm getting nothing. Help! P.

Items disappear from Catalog when updated
by Joel Burton 14 Mar '01

14 Mar '01

I have a ZClass (JBook) which is CatalogAware as its first class inheritance. When JBooks are added, they are added to the Catalog (default name, root level). However, if I request an update, the books are removed. Only the documents that were present when I did the last manual 'Find Objects' are kept. Can anyone shed any light on this? Many thanks, -- Joel Burton <jburton(a)scw.org> Director of Information Systems, Support Center of Washington
