Re: [Zope-dev] XPath and Aquisition Incompatible?
Josh Zeidner wrote: hi, I was just looking over the Wiki on Zope XML, and came across the current notes on XPath. I tend to think that XPath( which is a relative discripition of a tree traversal ), and Aquisition( which implies quite a bit based on where it gets executed )- may not be exactly compatible. Has there been any discussion on this? No, but there should be and I'll put it as a section under Martin's DevelopmentStrategy page -Josh Z Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope ) -- Chimezie Thomas-Ogbuji Consultant Fourthought Inc.

[Zope-dev] ZDOM alpha release 2
See release notes for changes (installation process simplified w/ release of 4DOM/4XSLT/4XPATH): -- Chimezie Thomas-Ogbuji Consultant Fourthought Inc. (303) 583 9900 ext 104 [EMAIL PROTECTED] ZDOM is the result of a collaborative venture by Digital Creations and Fourthought Inc. to integrate the W3C Document Object Model interface with Zope, allowing effortless and familiar traversal of a Zope heirarchy. The current alpha release is based on Fourthought's 4DOM , which is one component of Fourthought's 4Suite. Fourthought provides custom technological solutions based on open technologies. 4Suite is a powerful set of Python tools developed by Fourthought for Web-based applications in areas such as Intranets, E-Commerce and knowledge-management. Elements of 4Suite have been adopted as core XML technologies in Zope and in the Python XML distribution The necessary files (which are all available on our ftp server: ftp.fourthought.com) are ftp://ftp.fourthought.com/pub/mirrors/python4linux/redhat/i386/python-xml-nodom-0.5.4-1.i386.rpm (Py-XML w/out DOM) ftp://ftp.fourthought.com/pub/mirrors/python4linux/redhat/i386/4DOM-0.10.0-1.noarch.rpm (4DOM core) ftp://ftp.fourthought.com/pub/4Zope/ZDOM-dist.tgz (ZDOM) ftp://ftp.fourthought.com/pub/4Zope/Zope-ZDOM-Patch (patch file for Zope 2.1.6) OR http://www.zope.org/Members/anthony/patches/4ZDOM-vs-CVS-0512.patch (patch file for CVS/alpha 2.2 Zope) Documentation: ftp://ftp.fourthought.com/pub/4Zope/INSTALL.txt (the installation instructions) ftp://ftp.fourthought.com/pub/4Zope/Readme.txt (short description of ZDOM) ftp://ftp.fourthought.com/pub/4Zope/Release.txt (release notes) links: Fourthought: http://fourthought.com 4Suite: http://fourthought.com/4Suite/ DOM 2 Spec: http://www.w3.org/TR/2000/CR-DOM-Level-2-2307/ Zope http://www.zope.org contact: [EMAIL PROTECTED] Installing ZDOM --- This document describes installing ZDOM on Unix. Important Notes ZDOM REQUIRES ZOPE AND PYTHON 1.5.2! Depending on which Zope version you wish to add ZDOM to, there are two patches to download 1) ftp://fourthought.com/pub/4Zope/Zope-ZDOM-Patch (patches Zope 2.1.6) 2) http://www.zope.org/Members/anthony/patches/4ZDOM-vs-CVS-0512.patch (Anthony Baxter's patch which works on the CVS source tree as of 5/16) ftp://ftp.fourthought.com/pub/mirrors/python4linux/redhat/i386/4DOM-0.10.0-1.noarch.rpm (4DOM core) ftp://ftp.fourthought.com/pub/4Zope/ZDOM-dist.tgz (ZDOM) ftp://ftp.fourthought.com/pub/4Zope/Zope-ZDOM-Patch (patch file for Zope 2.1.6) OR http://www.zope.org/Members/anthony/patches/4ZDOM-vs-CVS-0512.patch (patch file for CVS/alpha 2.2 Zope) Installing First download these files from our FTP server: /pub/mirrors/python4linux/redhat/i386/python-xml-nodom-0.5.4-1.i386.rpm /pub/mirrors/python4linux/redhat/i386/4DOM-0.10.0-1.noarch.rpm /pub/4Zope/ZDOM-dist.tgz /pub/4Zope/Zope-ZDOM-Patch OR http://www.zope.org/Members/anthony/patches/4ZDOM-vs-CVS-0512.patch Install the rpms and decompress ZDOM-dist.tgz somewherer in your PYTHONPATH Install and build Zope 2.1.6 if not already done. This is required for the components to work. The following will install the patches to Zope objects to allow manipulation of Zope object via the DOM interface: (the Zope2.1.6 patch assumes that the Zope src files reside in a 'Zope' directory so a symbolic link is necessary) ln -s [Zope install dir] Zope cd (parent directory of Zope install dir) -- if necessary patch -p0 (location of dowloaded files)/Zope-ZDOM-Patch OR 4ZDOM-vs-CVS-0512.patch Then add '(zope install dir)/lib/python' to your PYTHONPATH. RELEASE NOTES - 5/30/00 changed setAttributeNodeNS to check for aq_base and set to None if it doesn't exist (since _setProperty expects aquisition to be set up -- but might not be necessarily so since an element can be created and attributes can be added WITHOUT it having a parent yet) redirected computed attributes to instance methods so DOM interfaces can be overode added check for aq_base in setAttributeNodeNS (sets to None if it doesnt exist) 5/10/00 ZDOM alpha supports to complete DOM Level 2 Specification (http://www.w3.org/TR/DOM-Level-2/) ZDOM maps the DOM interface to Zope, like so: childNodes - objectValues() mappable subset of DOM 2 Interface - attributes - propdict() parentNode - self.aq_parent Default implmentation of both objectValues() and propdict() are provided on SImpleItem.Item for Zope Objects that do not implement these interfaces. All Zope objects support the DOM Level 2 spec through the inheritence of SimpleItem.Item from Element. All objects (except as noted below) created by the use of the DOM interface (i.e., NodeLists, NamedNodeMaps, childNodes for Attr) are transient. All Zope
[Zope-dev] XMLDocument beta release 3
See release notes for changes (installation process simplified w/ release of 4DOM/4XSLT/4XPATH): -- Chimezie Thomas-Ogbuji Consultant Fourthought Inc. (303) 583 9900 ext 104 [EMAIL PROTECTED] XMLDocument beta is a collection of Zope products and python tools that integrate XML into Zope, above and beyond the current XMLDocument product. Like ZDOM, it is the result of a collaborative venture by Digital Creations and Fourthought Inc. XmlDocument This is a Zope product that wraps XML content for use in Zope. In many ways it behaves similarly to the original XMLDocument, except it only creates a single Zope object upon import or creation. XMLImporter This python module allows users to externally import XML content into the Zope database in a 'controlled' manner. The user has full range of control over import parameters. XSLT Method This is a Zope product that wraps an XSLT stylesheet for use in Zope. Like a DTML method, it can be invoked on a ClobXmlDocument instance and return the resulting XSLT transformation. Fourthought provides custom technological solutions based on open technologies. 4Suite is a powerful set of Python tools developed by Fourthought for Web-based applications in areas such as Intranets, E-Commerce and knowledge-management.

Point your browser to where you imported testfolder in the zope heirarchy and follow the directions. NOTE: The demonstration cyclicaly creates and destroys a ZDOM heirarchy in testfolder/, so if you stop it at mid point it may break if you try to restart it (if it's broken run the reset DTML Method: which simply removes folder1, folder2, and ZDOMtester) Installing XMLImporter: decompress XMLImporter-beta.tgz to an arbitrary directory. make sure (Zope install directory)/lib/python is in your PYTHONPATH * read the python files in test_suite for examples on how to use XMLImporter Assuming you've satisfied the dependencies, you should be done! questions? email: [EMAIL PROTECTED] RELEASE NOTES 5/30/2000 1) Solved __call__ problem, XSLTMethods can be invoked programatically 2) Added a default view for XMLDocuments that can return the XML as: syntax highlighted HTML raw XML plain text this can be specified by the output property 3) fixed the copy paste bug 4) added demonstration/example to package 5/16/2000 Moved ClobXMLDocument and XSLTMethod to seperate products changed ClobXMLDocument to XMLDocument ___ XMLDocument beta supports the import and manipulation of XML files in Zope through the use of XSLT. See (XPath: http://www.w3.org/TR/1999/REC-xpath-19991116, and XSLT: http://www.w3.org/TR/1999/REC-xslt-19991116) XMLImporter is currently used as a python based tool to input XML files as Zope Objects. The mapping functionality and XSLT transform are used to manipulate the incomming XML stream into a set of Zope Objects. The transform is applied to the incoming XML to allow manipulation and compression of the incomming XML. See http://216.164.72.7:7780/Wiki/Members/jim/ZDOM/InitialNotes under the heading optimization. The final set of objects created by XMLImporter is defined by the mapping dictionary where keys are the tagNames to be created, and the values are references to python classes. A current limitation of the system is that Zope must not be running during an import. Clob XML Document is a Zope Object that represents a complete XML document. Interfaces are provided to edit the content of the document, and modify how the document is displayed when viewed. XSLTMethod is a Zope Object that applies an XSLT transform to an object. An XSLTMethod can be accessed as any other method of an object. With the ZDOM pakage installed, the XSLTMethod can

I added another note on the Wikki regarding the XSLTMethod __call__ issue, more information on the ZPublisher is neccessesary for any progress. Is there any good documentation on the subject?
