Hi All!
Basically all my question is in title: how to apply XSLT to XML on the server in JSP or ASP without DOM?
I have data.xml file and style.xsl file. If user access my page (either JSP or ASP or doesn't matter) with browser that supports _full_ XML + XSLT, than I just send to user file data.xml, user's browser processes it, finds reference to style.xlt, retrieves it and process both to the end result. If user uses outdated browser (no XML/XSLT or old versions), I do the same on the server.
Example of such script on server side:
<%
dim xmlMenu
dim xslMenu
'Get the source XML
set xmlMenu = server.CreateObject("Msxml2.DOMDocument.4.0")
xmlMenu.async = false
xmlMenu.load server.MapPath("data.xml")
'Get the XSLT to transform the XML
set xslMenu = server.CreateObject("Msxml2.DOMDocument.4.0")
xslMenu.async = false
xslMenu.load server.MapPath("style.xsl")
'Transform the source XML using XSLT
Response.Write xmlMenu.transformNode(xslMenu)
set xmlMenu = nothing
set xslMenu = nothing
%>
I want to have exactly the same but without DOM, because it takes a lot of memory (well, I personally didn't notice that. The above script processed 8MB file with 16,000+ nodes in 25 sec on my development PC (256MB Ram, P4 1.4, Personal Web Server + MSXML) to table-like HTML. But people say 4MB file takes > 100MB of RAM and is slow. May be they mean "stress testing"?).
I cannot use anything except ASP or JSP - no COM, C++, ActiveX or other stuff. Not that _I_ don't want to, but that's an in-house rules  (((((
Thanks a lot for answer!
SY-
Kosta.

You want to apply XSL to XML, without an XSL parser of any kind ? How, exactly ? I don't think it's possible unless you write your own, and if your management insists you do it this way, I suggest you look for another job, and use the word 'morons' liberally in your resignation letter.
I'm sorry, I don't see how it can be done.

Well, I could use MSXML.
In fact, posted ASP script uses MSXML (I corrected my original question by adding some performance test numbers). But, if I right understand (may be I'm wrong here? - I'm complete novice with XML and ASP  ), that script creates DOM object by calling "CreateObject" method. And I've seen posts in this forum that DOM is slow and takes a lot of memory. I found out that SAXON might be solution, but again - I cannot use any 3rd party software 
I try to rephrase queastion - is it any way to run XSLT processor withing ASP or JSP without using "CreateObject" method?
And by the way - they are not morons. They are US government . Well, may be they are after all Tssss.

MSXML is a COM object, it requires CreateObject and is based on the DOM.

Correct.

Every idiot has an opinion. Yes, DOM is bigger than SAX, but I don't see what option you have. I dunno if there are SAX XSL processors, but either way, you need a processor to do the processing.

Yes, write one yourself in ASP.

Yes, To be honest I do not think the US is unique. I do have experience working with the Australian government also.

Yes, Look at the Apache XML code XALAN http://xml.apache.org/. For large processing it does not require the resources for a DOM implementation. That is the real issue (IMO), if you are having to go to disk to handle a DOM implementation and not for a SAX. If you know you have the resources I find that DOM works just as well. A warning though, The processing can be different between the two. A XSL file for one will not always give the same results when applied to the other.
If that is not acceptable. MSXML does have a SAX implementation. See
http://www.perfectxml.com/msxmlSAX.asp

I have always been intrigued by this statement. MSXML is not 3rd party but XALAN / Xerces is, but the Apache code I can down load and look through.

i would transfrom the xml - and output it to a text file or session variable.
then when you get a request check the date of the xslt & xml file - if either are new regenerate the output.
otherwise just return the file/session variable as the output.

OK, I finally found answer (sort of) to my question and it is "SAX Parser with ASP" article at
http://www.experts-exchange.com/Web/Web_Languages/XML/Q_20150239.html
Here is copy of code from there (in case anyone interested):
<%Response.ContentType = "text/xml"
Dim generator, ch
' instantiate XML generator class
Set generator = Server.CreateObject("XMLFilesVBSAX.CGenerator")
Set ch = Server.CreateObject("XMLFilesVBSAX.CSerializer")
ch.RegisterOutputStream Response
generator.generateXML ch
%>
Then ->
<%Response.ContentType = "text/xml"
Dim reader, ch
' instantiate XMLReader class
Set reader = Server.CreateObject("MSXML2.VBSAXXMLReader.3.0")
' instantiate class that implements IVBSAXContentHandler
Set ch = Server.CreateObject("XMLFilesVBSAX.CSerializer")
ch.RegisterOutputStream Response
' turn off namespace prefixes
reader.putFeature "http://xml.org/sax/features/namespace-prefixes", False
' register ContentHandler implementation
Set reader.contentHandler = ch
' begin processing document
reader.parseURL "file://c:\temp\whatever.xml"
%>
And lastly ->
<%
Dim reader, ch
' instantiate XMLReader class
Set reader = Server.CreateObject("MSXML2.VBSAXXMLReader.3.0")
' instantiate class that implements IVBSAXContentHandler
Set ch = Server.CreateObject("XMLFilesVBSAX.CInvoice2HTML")
' turn off namespace prefixes
reader.putFeature "http://xml.org/sax/features/namespace-prefixes", False
' register ContentHandler implementation
Set reader.contentHandler = ch
' begin processing document
reader.parseURL "file://c:\temp\whatever.xml"
%>
Thanks for everybody!

Thanks for this info. I've never used SAX, and I did not know it could parse XSL. However, I note you've had to call 'CreateObject', I thought you were not allowed to ? :P

I am not allowed to create my own objects, but I could call existing ones
As far as I understand, government want to have all their projects to be written in one - two languages, so they could get rid of contractors after project finished and hire some idiots fresh from college to support all this trash

Fair enough. In that case, I don't understand why you could not use the DOM, although it's certainly the case that SAX is more lightweight. I'm glad you asked this, I will use SAX myself in future in places where I've used to DOM.

*grin* I see. In that case, I can see why 'no C++' was a requirement.

Hey Guys,
I've got an app that dumps some data as XML and I want to be able to use this data as the basis for a HTML report.
So, knowing nothing about XSL, can XSL do it for me? If so, can anyone give me some pointers about where to look?
Cheers
James

Most definately, it is all just well formed text really.
Here is a good tut on it.[^]
Just remember it is all text and you won't go wrong. Don't get hung up on the buzz words sounding different.

Am encountering the following problem.
in my xml doc, there is elment as such:
<COMMAND function="Write"><![CDATA[$:set:mode EG]]></COMMAND>
the corresponding autogen xml schema from VS.NET returned
<xs:element name="COMMAND" minOccurs="0" maxOccurs="unbounded" >
<xs:complexType>
<xs:attribute name="function" form="unqualified" type="xs:string" use="required"/>
</xs:complexType>
</xs:element>
my understanding is the CDATA tag is asking the xml parser to ignore what is enclosed by the CDATA tag. By the same token, i would think the xml schema should also ignore the element value of COMMAND.
well, I isolated the xml schema validation is failing at this point. How should the xml schema really be to handle CDATA?
thanks,
huikm

Our app transforms xml data with xsl into html.
I use &#160;&#xD;&#xA; (space, carriage return, line feed) to separate data on different lines that eventually is displayed on an excel spreadsheet. After each line is a square that is undesirable.
Can anyone please tell me how to get rid of this square or how to display a line feed without it?
Thanks,
Lilian

|
|
|
|
this is realted to either:
&nbap;* your character encoding in your xslt
* or the fact that excel is not recognising the line feed - try missing out the line feed.
hope this helps.

|
|

After I retrieve the transformed CComBSTR that is produced with XML and xsl, I wrote code to parse through the wstring to replace the CRLF with a \n. I guess Excel didn't like what xsl did to it.

A long time ago, I found an article on MSDN that had all the info for what version of the MSXML parser was included with what version of IE. Does anyone have a referece such as this? It was something as simple as:
IE v4.0 contains MSXML2
IE v4.1 contains MSXML2
...
IE v6.x contains MSXML3 (???)
Writing an app and if I know what version of XML was included with what version of IE (which is the standard browser), I know where to start. Know I'll need this in future apps.
Thanks!

Aaarrgghh, poor chap. You are supposed to reward people for helping you, not subject them to the horrors of the *eery eye twitching music maestro* The Christmas Fruit Cake *crash of lightining, womens scream, eye of knewt, wing of bat...*.
Actually so long as there is no more than a milimetre of marzipan on the damned thing, I like fruit cakes (no, not those kind of fruit cakes all you sickos... I mean the one your auntie gives you and your mom keeps you away from in case you actually try to eat it! Most end up as doorstoppers or as "next years christmas" gifts)
