DTML Method truth value
by David Ascher 05 Mar '99

05 Mar '99

The following method tests false (correctly):   But if I change it to:     then it tests true (note that nothing happens in the #in block). Is this correct behavior or one for the Collector? --david

XML discussions
by Robert OConnor 05 Mar '99

05 Mar '99

Hi Paul and Zopesters, Paul writes in the thread: [Zope] Some tough questions about zope... >I've been awfully interested in XML in >the last few days. Can you describe what >user-visible benefits PHP delivers due to its integrated >XML parser? I found a great description about XML in: "20 Questions on XML" http://builder.com/Authoring/Xml20/index.html On Paul's Zope roadmap: (Jan 18th) http://www.zope.org/Information/Roadmap "(2) XML. Zope is a great fit for XML, even better with the machinery from Tabula going in. We also see XML becoming the basis for other initiatives, such as WebDAV and RDF. However, we just can't squeeze out the time to dive in deep. Rather, we'd love to see more community progress like that which popped up this weekend." I did a search for postings that had "XML" in the subject and found 55 messages in ~6 threads between Jan 8th and Feb 2nd Other messages have "XML" in the body. Hopefully we can get some OUTLINE of how ZOPE and XML can work together. --- A framework for further discussions. -bobo connor bob(a)rocnet.com

Simple DTML Method/Acquisition problem
by David Ascher 05 Mar '99

05 Mar '99

I have a standard_html_header/footer pair which works much like that on zope.org. The header inserts a  in the left column. The sidebar DTML method is:    <a href=""></a><p>   (show links to sub-folders which don't have the 'hidden' property set). The above works fine in the toplevel folder. In the subfolder, however, nothing shows up, even though there are two folders which do qualify. I'd tried originally to have it be a DTML Document and change the expr to _.objectValues(['Folder']), but that doesn't work at all. What am I missing? --david

evaluating attribute values
by Robin Dunn 05 Mar '99

How can I evaluate a #var equivallent for setting a tag attribute value? For example, Zope doesn't like this:  --> or this:  (it tries to use smtpHost as the host name, instead of its value) Help! -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ http://AllDunn.com/wxPython/ Check it out!

Documents for web and paper
by Robert OConnor 05 Mar '99

05 Mar '99

I'm looking for the best way to store and retrieve documents with these requirements: SPECS *Easy storage and retrieval on the web *Pretty printing on paper *Easy simple collaboration (no checkout) *One BASE format for both web and paper *Base format *could be* edited with Word or WP *Preserve text markup: bullets, bolds, underlines, tables, graphics, links...etc. *Search by keyword *Search by full text ******* I look forward to comments and Ideas on implementing this in ZOPE Perhaps some of this has been solved already and I don't know it. EXAMPLE: Say you have a small book/article that is fully contained in a WORD or WP file. It has chapters and sections: Chap1 Plants Section1: Trees Section2: Flowers Section3: Vegetables Section4: Fruits Chap2 Animals Section1: Dogs Section2: Cats Section3: Fish Section4: Humans Ok, as a paper document in the word processor it is laid out *nice* with a new page for each chapter, section, and subheadings for groups of paragraphs in each section. It prints *nice* and can even have a table of contents and index. For the web, the whole book could be one LONNNG web page. Ugly and it doesn't work well. Ideally on the web each chapter and section would be navigable with a left hand frame like table a la http://www.zope.org. Then sections can be placed on separate pages on the right. This means that the one source document becomes multiple html "files" on the web site. *Tree Navigation Ok, for tree navigation like http://localhost:9673/QuickStart Each Chapter and Section becomes a folder and the text from each section is contained in the same named: "dtContent" as in ...9673/QuickStart/Outline/Applications/External/dtContent While the tree is nice, and separate html "files" make the website better, *REVISIONS with TWO OUTPUTS How do you do: Make revisions to the source document in word/WP and have it FLOW automatically to html format or tree format for the web? *Perhaps* XML could come to the rescue as holy grail to help solve this problem??? I understand the idea of mark up but how does it solve the problem of two outputs? Can you have a template that automatically chops up the SOURCE into the appropriate folders/files etc and feeds it to ZOPE? Can this or another template reformat for pretty printing including page numbers that are updated based on the planned printing? Maybe I need to reconsider how documents are stored as source, i.e. not Word. And if not, what tool or mechanism would be best? Maybe the NATIVE source could flow to Word/WP or via a template making for pretty printing. Maybe for simple stuff, the source could be simple text entered on a webpage or sent by e-mail with *simple* markup and parsed automatically? *KEYWORD SEARCH Ok, on the web (and Zope), the benefit is it's searchability: Do we "hide" keywords in the source somehow and in addition use Chapter and Section titles as Keywords? Search for: "dogs" gives a result of Chapter 2 Section 1 in the example as one entry. Additional entries might be lessor cross references such as a keyword "dog" in the Section 4 humans as "man's best friend". *FULL TEXT SEARCH Ok so we search for the word "Daisy" and this word is found in the text in sections: Flowers, Dogs (as a pet name) and Humans (as a proper name). The result is then three line entries that take you to the words. *Zope IDEAS for this? I assume that it would be best to store the documents and source in the ZOPE database rather than an external datasource. Thanks for any input on this -bobo connor bob(a)rocnet.com

Yes. ZServer really restores Zope's original intent from the Bobo days: publishing objects through a variety of protocols. I think ILU support was once attempted back in those days. However, a Bobo app at that time could only have one publishing mechanism (ie, CGI, PCGI, FastCGI, ILU, etc...). ZServer allows for multiple publishing mechanisms in the same application, allowing access to the objects through the web, through FTP, or through any other protocol developed for ZServer/Medusa. .jPS | jeffrey(a)digicool.com zope, through the web. www.zope.org

If you want to look in this direction, probably the best idea would be to write a Medusa handler. Check out Sam's site at: http://www.nightmare.com/medusa There currently exists an ftp and http medusa handler for Zope, which you can look at in the latest ZServer alpha release availabe at zope.org. I'm not sure is there is a Medusa CORBA handler or not, I suspect not, but maybe there's some type of CORBA out there written in Python? -Michel > Jody > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope >
