local characters and ParsedXML
by Juan Manuel Ruiz Garcia 17 Dec '02

17 Dec '02

Hi all, I want to know if someone is working with ParsedXML, using local characters, like stressed vowels (spansih, french, german...) and so on... The point is that when I specify the correct encoding at the ParsedXML editForm if I press the "save changes" button, that encoding disappears and the special characters are changed for strange chars. If I try to view the document in explorer, it crashes because of that chars. If I don't specify an special encoding, the save changes button does not works if the xml doc has any of the special characters (which seems to be reasonable) But the strange thing is that I can manipulate via python scripts the info of that XML document, I can write stressed vowels inside it, and I can read it later, but once again I can't simply view the xml document in the navigator, I get an error because of an invalid character. What can I do to make all this work?? Is there any way to write an encoding for the parsed XML whitout being removed automatically from it when I save changes? Thanks in advance ___________________________________________________ Yahoo! Sorteos Consulta si tu número ha sido premiado en Yahoo! Sorteos http://loteria.yahoo.es

MSWordDocument
by Jose Angelo P. Abarentos 17 Dec '02

Hello Zopistas, I've been wrestling with Eric Barroca's MSWordDocument product for days now, trying to get the HTML version of a Word file to output on my DTML document. I've tried: <dtml-var name="MyWordDoc"> but it seem to only print "MSWordDocument instance at... ". I also went to the product's source and saw a method that looks like what I needed, getDocHTML. So I tried: <dtml-var expr="MyWordDoc.getDocHTML()"> but now it's giving me an "AttributeError". I'm relatively new to Zope and Python so I would really appreciate it if any of you more experienced Zope people could care to help. -- Angelo Abarentos, a Zope newbie

Whoa there! What's up WebDAV???
by Bryan Capitano 17 Dec '02

17 Dec '02

I'm just experimenting with Dreamweaver MX + WebDAV + Zope for the first time. When I open up a Zope Page Template (ZPT), all my TAL syntax disappears. And then when I go back to Zope's ZMI and look at the ZPT, indeed all my TAL expressions are completely wiped out!! What's up with that? I think this defeats the whole purpose of being able to edit ZPT's through Dreamweaver+WebDAV, no? I want to retain the TAL expression syntax round-trip back and forth from Dreamweaver. Is there a way to do this / "fix" this ?? Thanks, Bryan

dtml syntax- check file existence
by Sean Kelley 17 Dec '02

17 Dec '02

Hi I need help checking the existence of a file in a sub folder. if file(graphic) in sub folder exists display graphic else display message that there is no graphic The tricky part of this for me is that I have an ID for a graphic which is available in a <dtml-in> loop so the graphic I am testing the existence of is named "id.thumb.jpg" and is in a sub folder so if I do another dtml-in my ID is not available in the second in loop. A partial failed example: <dtml-in photos2> <dtml-if <dtml-var id>.thumb.jpg> // I know this is not right <img src="/photos2/<dtml-var id>.thumb.jpg"> // and know id is not available at this level but not sure how to pass it along. <dtml-else> no image </dtml-in>

Re: [Zope] ZClasses and FTP/WebDAV

One thing that is a pain about ZClasses is that when you want to call the method of a particular superclass, you have to do some really nasty digging with an external method to specify it, unlike in python products. This seems like it might be related to your problem. You would want to simply have your class call the manage_FTPget, manageFTP_list, manage_FTPstat, and PUT() of the PageTemplate class. In python, you would do this like: class A: def manage_FTPlist(self,REQUEST): #do something here class B(A): def manage_FTPlist(self,REQUEST): return A.manageFTPlist(self,REQUEST) But, alas, you need to get a reference to the class A, which is very hard in a ZClass. You could do likely this with some very deep digging in an external method (something resembling this): def getPageTemplateClass(self): clist = self.___class__.__bases__ #get tuple of all base classes for superc in clist: if superc.__name__ == 'ZopePageTemplate': return superc #return the ZPT class return self.__class__ #fallback/default: return our own class You would then need to create external methods for each of the 4 FTP methods named above and call the appropriate method of the ZopePageTemplate class returned by the above external method. The said methods would use the above method to get access to the superclass A lot of this might be easier in a Python product. The Zope Bible is a pretty good reference/tutorial for building products. My guess is that trying to do this as a ZClass would actually be harder than as a Python Product. Sean You wrote: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> My ZClass is based off Page Template and CatalogAware (vis a vis a CatalogAware wrapper for Page Templates! Is there any reason the developers are not making older types CatalogAware to save us this trouble and make the ZCatalog that much more usefull? I digress.) I had hoped the inheritance from Page Templates would have handled the required functions, but it does not. I can see where I might begin to move towards a solution in a Python Product, but not at all with a ZClass. It's a pity, as I'm so very close to being where I want with this. If anyone has any further thoughts on manipularing the inner workings of a ZClass, I'd find that tremendously helpful. In lieu of that, a primer on how to make a Python Product would be nice as it looks like I'll be working overtime... But, for the time being, I'll work with the ancient patch mentioned previously to see if I can incorporate the features I desire into Zope 2.6 Ed

HOW TO COUNT VARIABLE WITH <DTML-IN>
by Mike Doanh Tran 16 Dec '02

16 Dec '02

How do i count the value of a variable inside of <dtml-in> I want to count not just the occurence of the variable but the value of that variable also. For Example i have a variable name "weight": <dtml-in getQuery> <dtml-var count-weight> </dtml-in getQuery> <dtml-var count-weight> will give me a total number of occurence for the variable weight. What i want to do is count the value of weight. if weight=1 then count how many 1 there are if weight=2 then count how many 2 there are and so on .... I've tried to used <dtml-let> to initial a variable but can't do it. Does anyone have any suggesstions on how i can do this using DTML? Thanks for any suggestion, -- Mike

Add multiple photos
by Bin Zhang 16 Dec '02

Can someone tell me how to add multiple photos into a Photo Folder in Zope? Can you use FTP or WebDav to do this? I would like to upload a photo album from a CD and hope that I don't have to add them one by one by hand. Thanks for your help. Bin

Yes, you can use FTP. Create the Photo Folder via the ZMI, the upload jpg files via FTP to the folder.

I've done searches for the file with no sucess, so I gave up and looked specifically for something to do a MSWord2HTML, this is one I found. http://www.wvware.com/ I havn't tried it yet, and I will look to see what the error message was for MSWordDocument.

ZClasses and FTP/WebDAV
by Edward Pollard 16 Dec '02

16 Dec '02

Can anyone bring me up to speed on why my ZClasses cannot be manipulated via FTP/WebDAV, and what I need to do to make them so they can? I was pleased to note that built in Zope objects perform admirably during FTP/WebDAV manipulation : I'd feared that changed files would revert to 'File' objects. (Irrational, I know). However, my lovely ZClass, that I've put so much time and energy into, does not work. In FTP - I just get an error when I try to replace it. (Downloading is fine) In WebDAV - it sees my ZClass as a Folder. Downloads it as a Folder. Wierd. I'll be happy as can be to get one of theses methods working. This is imperative as we use Dreamweaver as our site manager/editor. Now, I've found this: http://www.zope.org/Members/akendall/zclassftp Seems relevant, but old as can be. I'm going to compare the files it alters with the ones that come with Zope 2.6, and hopefully I can distill some wisdom as to what needs changing. But if anyone can shed some light to help guide my way, I'd appreciate it. Ed
