RE: [Zope] XML

Download and use ParsedXML product (v. 1.3+), which created persistent DOM documents; use standard DOM API to access, traverse, read, and write data from these documents. This will require that you have the PyXML package installed for the version of python you are using to run Zope in your linux distro (http://pyxml.sf.net) Note: PyXML is used to provide the pyexpat parser interface to the expat parser, included. You might also be able to parse your document without storing it in Zope without even using ParsedXML (it sounds like this is what you want to do?). If this is what you are looking to do, use the PyDOM dom implementation that comes with PyXML, and write a parsing script in a Python module; then write an external method that uses that module. This should be pretty easy. Get a copy of the book Python & XML by Jones and Drake (O'Reilly, 2002). Also, there is a Parsed-XML-Dev mailing list and a zope-xml list, both on zope.org.

Rick Anderson [mailto:ruger@acsnv.com] Sent: Thursday, March 06, 2003 12:09 PM To: zope(a)zope.org Subject: [Zope] XML What is the best way to parse XML with Zope? I've been digging all over the site, and the docs there keep talking about adding an XML Document, but that option doesn't exist on my Zope server (2.6.0 on RH 8.0) and I can't find anything indicating that there needs to be a product installed. Simply put, I want to be able to grab an XML document with webclient() and be able to parse the contents of the XML using DTML.

Is there an easy way to tell if a Page Template is valid/invalid? (Meaning the same check that gets done to see if the red exclaimation mark should show up in the ZMI) Ed

Zope vs Twiki - Can someone provide a comparison
by Nesbitt, Steve 07 Mar '03

07 Mar '03

All: I'm expecting a showdown between those who want to standardize on Twiki and me, who doesn't mind Twiki, but doesn't want to move away from Zope/Plone. Can anyone provide a quick overview between the two systems. In particular: 1) What problem space do the two systems address? Are they the same space or different space? 2) Where does Twiki shine in comparison to Zope (with Plone) 3) What things are hard to do in Twiki that are easy to do in Zope and vice versa? I need a compelling argument for not converting my existing site to Twiki. Any help would be appreciated!

context of a for loop
by Fearless Froggie 07 Mar '03

07 Mar '03

Hi, When you are going through a for loop, are you in the context of that for loop variable? Can you drop out of that for loop context and into the context of the script? Example: If I loop through a list of id's with a for loop and do something to each of these objects, I get a "You are not allowed to access editMetadata in this context". Here's the code (here I'm just changing the title of each of my items in my list 'id' to 'bob'): for item in id: item_object = getattr(context, item) item_object.editMetadata(title='bob') But if I do these changes directly, it works fine: item_object = getattr(context, id[0]) item_object.editMetadata(title='bob') So I'm guessing that the for loops puts me into another context. How do I get into the context of the object I want to edit? I've tried "context.item_object.editMetadata(title='bob')" and "container.item_object.editMetadata(title='bob')", but they didn't work either. My script in all these cases is my custom skins directory. Many thanks for any ideas on this. (And thank you once again for all the great ideas I've received for my past emails :) Rita. __________________________________________________ Do you Yahoo!? Yahoo!

sending form data offsite
by Ed Colmar 07 Mar '03

07 Mar '03

Hi fellow zope hackers! I'm building a site for someone who wants to have the entire site within zope, to connect to dbs, etc... But they use a service that requires them to post form data to a master server. Is there an easy way (in dtml or python) to do this without seeing the data transfer or ending up at th other server's pages? So far I've considered making an external method that uses lynx and dumps the return data. Is this the best way? Thanks for the help! -ed- -- Green Graphics ::: Print and Web Design ::: 510.923.0000

squirting variable definitions into macros using fill-slot
by Felix Ulrich-Oltean 07 Mar '03

07 Mar '03

I have a macro like this: <metal:block define-macro="conf_form"> <div class="something" tal:define="chosen_thing request/chosen_thing|here/chosen_thing; the_name request/the_name|here/the_name"> <input type="radio" tal:attributes="name the_name; checked python:chosen_thing=='a' or nothing;" value="a" /> a <br /> <input type="radio" tal:attributes="name the_name checked python:chosen_thing=='b' or nothing;" value="b" /> b <br /> </div> </metal:block> I will be using it several times from the same template. I want to be able to pass in values for chosen_thing and the_name, but I can't think how. If I define a slot, e.g. for the <div>, the stuff in fill-slot will replace all the stuff in the macro. Alternatively, I could use fill-slot and a 'global' definition, but then I wouldn't be able to use it more than once. Am I just being dumb here? It must be possible to pass in dynamic information using fill-slot. Thanks for any advice, Felix.

If I run three sites at- www.mydomain.com intranet.mydomain.com extranet.mydomain.com And I map them to the following locations in my Zope using either VHM or siteroot- /www /intranet /extranet Will I still be able to accquire objects in the root container? For example, a shared database connection?

NuxUserGroups: workaround, anyone?
by baiewola＠netscape.net 07 Mar '03

07 Mar '03

My zope site is already created, and I did not create it with the idea that I would be implementing user groups. Therefore, I already have an acl_users folder at the top level of my site. All of my users are defined in that folder, and all access throughout the site is inherited, except for a few local roles assigned here and there. Now that I want to use NuxUserGroups, I have a problem: I cannot create groups at the top level. Since I already have an acl_users folder, I get an error when I try to create a "User Folder with Groups" at the root level. So I can't simply move all my existing users into a different type of user folder that supports groups. And when I create a "User Folder with Groups"at any other level, of course my users from my root level acl_users folder are not recognized so they cannot be added to groups. So if I want to add groups at any level, I have to re-create all my users. Does anyone have a workaround to this? Or am I overlooking a product that will let me do what I want (add groups to an existing site at the root level)? __________________________________________________________________ The NEW Netscape 7.0 browser is now available.

sending a post request to a secure site (paypal) from a python script/external method
by Richard Ettema 07 Mar '03

07 Mar '03

I'm trying to work out how to setup a python script and external method to post form data to a paypal https url. I basically want the user to click a button to pay for their selection which calls the python script, their order info is saved for our records, and then the external script passes onto paypal's secure server. Is this possible? The closest I have got this to work is the palpay page displayed with images missing, but not on a secure connection. I assume the images are missing because the url in the address bar is that of the python script, not the paypal url. Should I be doing something different than a read() in the ext. method? I have looked thru the examples in the urllib.py and urllib2.py but could not work out where I am going wrong, or if it is possible. I have seen comments about python must be built/installed with ssl support for secure connections to https urls, how do I work out if python was built/installed with this? Running: system: freebsd Zope: 2.5.1 python: 2.1.3 The python script: payBill ######### req = context.REQUEST form_dict = {} order_ref = context.recordOrder() form_dict['cmd'] = '_xclick' form_dict['business'] = 'test@test' form_dict['item_name'] = 'Services' form_dict['item_number'] = '%s' % order_ref form_dict['amount'] = '%.2f' % float(req['gdttl']) form_dict['return'] = '%s/services_thankyou' % req['URL'] form_dict['cancel_return'] = '%s/services_thanks' % req['URL1'] form_dict['no_note'] = 1 form_dict['currency_code'] = req['currency_code'] #send info to external method url_req = context.payBillExt( 'https://www.paypal.com/cgi-bin/webscr', form_dict ) return url_req ########## The External Method: payBillExt ######### import urllib2 import urllib def urlRequestCreation(self, url, data): """url""" url_data = urllib.urlencode( data ) url_req = urllib2.urlopen(url, url_data) return url_req.read() ######### Thanks for any pointers in the right direction.

Does anyone know of a good module/product/hack that I can feed a date to and it will let me know if it's valid or not? It should check leap years ... end days of the month and the like...
