9.1 11/8/2002 (Craeg)

Added test for relative URL resolution
Added http scheme resolver for SabPyth
Added STATUS report for each processor to README file.

9.0 11/1/2002 (Craeg)

Fixed limitation where calling an XMLTransform directly as a DTML didn't work. That is, now
<dtml-var MyXmlTransform>

works when only

<dtml-var expr="MyXmlTransform(MyXmlTransform)">

worked before.
Fixed limitation where calling an XMLTransform directly as a ZPT didn't work. That is, now
<div tal:replace="here/MyXmlTransform">foo</div>

works when only

<div tal:replace="python:here.MyXmlTransform(MyXmlTransform)">foo</div>

worked before.
ZSyncing instances across xslt processors -- As of release 0.8, it was only possible to ZSync instances of XMLTransform to other Zope instances that had exactly the same set of XSLT processor libraries installed. This enables one to "upgrade" simply by ZSyncing to a machine with a different processor.
Added Sablotron support (SabPyth 0.52)
Added Pyana support (Pyana 0.6)
Upgraded to use 4Suite 0.12.a3 and PyXML 0.8.1
Upgraded to use libxml 2.4.26 and libxslt 1.0.22
Upgraded to use ZopeTestCase 0.5.3
Added ability to switch XSLT Processors on the fly. XMLTransform lists which processor is selected, and the transformer registry enables runtime selection among available processors.
XMLTransform mentions the processor it's bound to on its manage_editForm.
If transformer is a ZPT, make the XMLTransform behave_like zpt by default. otherwise, make it behave_like DTMLMethod by default

8.1 9/15/2002 (Craeg)

Removed inconsistencies in docs in spelling of XSLparameters
Added new Todos for behave_like (to match transformer when transformer is DTML or ZPT)
Fixed relative URL resolution on 4Suite 12
Fixed relative URL resolution on 4Suite 11

8.0 8/27/2002 (Craeg)

Added more functions to Cache Manager: list up to date, list out of date, and regenerate if needed
Noted potential issue with ZSyncer in README and TODO
All "if foo:" changed to "if foo is not None:" to guard against len(0)
Made 4Suite 11 the default processor
Wrote TUTORIAL.txt
Fixed bug where editing a transformer did not invalidate the cache
Ensured compatibility with ExternalFile 1.1, CVSFile 0.8.1 and ZSyncer 0.4.5

7.0 8/25/2002 (Craeg)

Refactored factory methods according to new conventions (pure python covers return new object, not a string)
Wrote README file
Fixed verbiage on all DTML ZMI screens
Added help text for all screens
Made FourSuite12Processor.py work with latest 4Suite 0.12alpha2+ (8/25/2002 CVS version). URI resolver patch required...
Implemented LibXsltProcessor.py for compabitility with GNOME libxml2 and libxslt

6.0 8/14/2002 (Craeg)

Add form now lists whether a cache manager is available or not
Refactored factory methods for all objects to allow them to be created either programmatically or via the ZMI GUI
Implemented unit tests for all objects
When you change the debugLevel property, in XMLTransform, it now changes the debug level in the underlying XSLTProcessor as well.
Implemented content_type attribute
Changed name of XSLTransformerRegistry to TransformerRegistry
Implemented behave_like functionality so can return either a DTMLMethod or a PageTemplate
Made FTP access work for XMLTransform, but only list the name (cannot edit transform nor source contents for security reasons)

5.0 8/11/2002 (Craeg)

Added ability to specify which meta_types can be transformers within an XSLTransformerRegistry. That way it will ignore other types of objects.
Added "omit" attribute. If an object contained within a registry has an "omit" attribute, it will be ommitted from the list of transformers regardless of its meta_type.
Changed XSLTransformerRegistry to be a folder-like object. All non-folder items that do not have an "omit" attribute will be considered transformers. The registry is now finally policy-free.

4.0 08/07/2002 (Craeg)

Created IXSLTProcessor interface, made 4suite 0.11 and 0.12 versions of implementation.
Enhanced CacheManager to check for existance of cache dir when cachePrefix property is set
Enhanced CacheManager to include delete cache functionality

3.0 08/04/2002 (Craeg)

Added separate CacheManager. Caching is now optional; it is done iff an instance of CacheManager is found.

2.0 07/29/2002 (Craeg)

Added separate XSLTransformerRegistry.

1.0 07/23/2002 (Craeg)

Changed name to XMLTransform
Removed ability to store content. It is now only a transformer, that points to another Zope object from which it obtains the XML document to be transformed.
Made product more modular by separating out Caching and calls to XSLT processor into separate Python modules. These modules could ultimately be made pluggable to allow different caching strategies or xslt libraries to be specified at run-time.

0.13 02/14/2002 (Craeg)

Refactored for compatibility with new CVSFile (0.7)

0.12 01/02/2002 (Craeg)

Fixed long standing bug where spelling error in self.contents silently created a new attribute on the fly
Integrated edit with ExternalFile to take advantage of edit via upload and Taller/Shorter buttons

0.11 12/18/2001 (Craeg)

Cache files now start with ZopeCache and omit the host name and port number

0.10 12/14/2001 (Chip)

Changed to _debugLevel. "0" means no debugging, "1" means some debugging trace, "3" means full template-by-template execution trace.
Fixed bug that made it impossible to turn off caching.

0.9 11/26/2001 (Craeg)

Cache will refresh itself in response to a modification of the underlying external file (if appropriate)

0.8 11/21/2001 (Chip)

Added ability to cache the result of the XSLT transformations. This dramatically improves performance.

0.7 11/18/2001 (Craeg)

Converted XMLDocument to use the 4Suite 4XSLT processor instead of Saxon. This obviates XML-RPC requirement.
Added URNResolver for xsl:include, xsl:import, and document() commands. Added ability to define URN namespaces in the ZODB and use them for lookup of local or remote objects. Local object lookup will use acquition. Remote object lookup uses URL streaming.

0.6 11/5/2001 (Chip)

Added the ability to pass xsl parameters to the transformer. See the README.txt file under "XSL Parameters" for more information.
Fixed bug: missing property_error object now inherits from CVSFile.

0.5 10/31/2001 (Craeg & Chip)

Added Help to Edit and Create screens.
ClassSecurityInfo now defines security.
Separated CVS information into separate management tab.
Added "Cancel Changes" tab to edit screen.
Fixed FTP get/put for both internal and external files.

0.4 10/30/2001

Incorporated new CVSFile (was ZCVSFile) forms and initialization functionality. XMLDocument is now an "optional CVSFile".
Redesigned how transformers are found. XMLDocument now obtains a list of transformers and presents them when the user attempts to create a new XML Document or edit an old one.
Changed the organization of the htmlLib to an xslFragments with html, pdf, etc. subdirectories. XMLDocument now uses this to generate the possible values of outputFormat.

0.3 10/23/2001 Incorporated ZCVSFile

Integrated ZCVSFile to allow the contents of an XMLDocument either to be local to Zope (part of ZOBD) or to refer to an external CVS-managed file.
Added a properties management screen to permit users to change certain values.
Separated notion of RPCServerURL into Server Host and Server Port properties. Removed cache property (for now).

0.2 10/22/2001 Refined design

Changed to inherit from SimpleItem to get acquisition working.
Made "catalog aware" and added indexing to creation method.
Defined __str__() to return the raw content, not the transformed content.
Removed the dependency on the dtml/xsl.dtml script to find the transformer object. Use direct Python calls, instead.
Wrote a better README.txt.
Now inherits from ZCVSFile. Edit form adjusted to accommodate.

0.1 10/18/2001 Initial Release
