Subject: RE: [xsl] Result still indented despite indent="no" From: Pieter Reint Siegers Kort <pieter.siegers@xxxxxxxxxxx> Date: Thu, 24 Feb 2005 08:54:41 -0600 |
Yeah Mukul, I know, but this is old news... I still see myself using WD-XSL, for what is what it was awesome. The big mistake MS made was not to follow the standard, I guess because they want to be the standard themselves (?) - it was a wrong decision. Now they know better - you can see that with decisions around bringing XQuery 1.0 or not in Whidbey and Yukon - leaving only a subset to come in the latter. That is after all a better decision, taking into account possible changes until the spec becomes W3C Recommendation. However, I still think MS's decision to exclude XSLT 2.0 from the big picture is a wrong decision. With Saxon.NET (https://sourceforge.net/projects/saxondotnet/) we're going to add it anyway, so no worries there - and there are more projects, like XQP (http://sourceforge.net/projects/xqp). I now realize this thread is way OT... which leads me to the original Q... has this been answered? I don't even see Sebastien comment, but it's the longest thread I've seen until now and with my 2 cents it's going to be even longer!! Anyone else? :-) Cheers, <prs/> http://www.pietsieg.com -----Original Message----- From: Mukul Gandhi [mailto:mukul_gandhi@xxxxxxxxx] Sent: Thursday, February 24, 2005 7:30 AM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: [xsl] Result still indented despite indent="no" I am sorry for another post on this subject! I am sorry if it annoys anyone.. I feel my duty to post this, as the views I expressed might have raised some doubts.. I just read an interesting article on Microsoft site about MSXML.. I have marked some phrases with * , which caught my attention more.. History of MSXML (quoted from Microsoft site) --------------------------------------------- When MSXML 2.0 first shipped, it introduced support for one of the first W3C XSL working drafts, which included a path-based language *known at the time as XSL Patterns*. It also included push-model interfaces available through the IXMLParser and IXMLNodeFactory interfaces. As time passed, the underlying specifications solidified. The original XSL working draft was factored into several independent specifications, including XPath 1.0 and XSLT 1.0. And during the same time frame, SAX evolved into the de facto streaming (push-model) API for XML documents. The *XML standards landscape* had changed dramatically and *MSXML had to follow suit*. The MSXML team shipped version 3.0, which *included support for these now stationary specifications*. But *instead of immediately deprecating the preceding versions, they decided to leave them in and make them the default implementation in order to foster backward compatibility*. Although the MSXML 3.0 components are installed in side-by-side mode by default, you can optionally run xmlinst.exe to place them in replace mode. *Replace mode forces older applications to load the newer components*(of MSXML 3.0). This decision ultimately backfired because it confused developers and *the replace mode made applications harder to maintain and somewhat fragile*. The confusion was evident on the MSXML-related mailing lists and newsgroups where a large percentage of the most common, recurring questions were directly related to the differing implementations. A similar issue existed with the XSL/XSLT implementations, only *it was subtler since the actual implementation was determined by the namespace in the transformation document*. You might argue that since all of this was clearly documented, developers should have known better. But in reality, no matter how good the documentation, *having too many options and not-so-obvious defaults always leads to confusion*. Problems like this one coupled with *the resulting confusion forced the MSXML team to simplify the library by completely removing the legacy code along with replace mode* starting with the July 2001 Technology Preview release. *But removing replace mode also means that you can no longer control which version of the XSLT engine is used by Microsoft Internet Explorer to process the <?xsl-stylesheet?> processing instruction that is often used to render XML documents*. *Internet Explorer 5.0 will now be restricted to MSXML 2.0 (or MSXML 3.0 in replace mode) until they deploy a new version written against the latest MSXML release*. Of course, Web developers can still use the latest and greatest XSLT engine, or any other new MSXML components for that matter, by simply referencing the appropriate version-dependent PROGIDs *in script*. Overall, these changes are positive for the future of MSXML. This sentence caught my attention most in the above artile(in light of this thread).. "A similar issue existed with the XSL/XSLT implementations, only it was subtler since the actual implementation was determIined by the namespace in the transformation document." I won't offer my further comments(as much has been discussed already).. I'll let readers to think(and experts to comment)..
