here's what I did, but we didn't run this production yet
1) construct one line of valid xml
2) write it to text file , flush buffer
This produced a text file that resembled xml, but missing the top-level node. To display it in a web page, I pre-pended a top-level node ( < TOP > ) , and appended a closing node name
( < / TOP > ), and this worked.
I think one possible advantage is that it is super fast and simple to write a line of text, and then you can take care of the leading and trailing niceties later when you display the file.
Also, this approach ignores the DOM entirely. It is only straight C text files at the time of logging.

We have done something similar, and for the first time files, if you check their existance before opening them, you can write out the xml header for a new file. You can also write out any trailer information, and if it is static, then when you open the file, you can re-position the file pointer (using fseek) to be that number of characters back from the end, write out your new data, and rewrite the static (ie, fixed/known length) trailer. It's a little clumsy, but it helps to know that you can re-position the file pointer.

This has been driving me crazy! I am trying to use XSL to output a nice pretty XHTML page from my XML feed. And of course, all nice pretty XHTML pages include a !DOCTYPE declaration. But whenever I try and simply stick it in my <xsl:template> tag, it gives me this error:
<br />
<br />
Cannot have a DOCTYPE declaration outside of a prolog. Error processing resource 'file:///C:/Inetpub/wwwroot/PageWriter/Template.xsl'. Line 13, Position 13<br />
<br />
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><br />
------------^<br />
I've tried a variety of things, such as splitting up the !DOCTYPE into various pieces and putting them in <xsl:text> elements, but that didn't work.
Anybody know the answer? This must be a fairly common question, not all XHTML and HTML outputs can be sloppily tossed out w/o a !DOCTYPE (i.e. like they are in all examples I can find).

Domenic,
I am not all that familuar with XHTML but can you post a little more of the transformation you are using and the output it creates. I at least do not see enough to comment on.

Well, in total its huge (10KB hand typed! I'm so proud of myself  ), but here are the relevant parts:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:XHTML="http://www.w3.org/1999/xhtml"
xmlns:MHC="/PageWriter/TemplateSchema.xsd">
<xsl:template match="/">
<xsl:processing-instruction name="xml-stylesheet">
<xsl:text>version="1.0" encoding="utf-8"</xsl:text>
</xsl:processing-instruction>
<!-- This is commented out because it gives me the evil error, how can I simply output this? -->
<!-- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US">
<head>
<!-- Irrelevant stuff here -->

<body>
<!-- Irrelevant stuff here -->
</boy>
</html>
</xsl:template>
</xsl:stylesheet>
Basically I just want to get that commented out part into my output, and because it has the sequence -Domenic Denicola- [CPUA 0x1337]

Have you tried to replace the <! character sequence with the string <! - that should trick the parser enough to work around the problem. Of course, change the closing > symbol at the end of the DOCTYPE to the string >

Yep. Didn't work, just outputted the actual text <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> at the top of the XHTML output document when viewed in the browser (IE6).
 Any other suggestions?

Yes - I forgot to mention that you need to enclose the modified DOCTYPE declaration within an xsl:text element, as follows (assuming that the XSL's namespace prefix is xsl):
<xsl:text disable-output-escaping="yes">
<!DOCTYPE html...>
</xsl:text>
That should work - famous last words...

The problem is your commented out line was being taken as instructions to the transformation processor not as output. Try Essam's suggestion as it is the simplest. And drop a message back. My concern is it may stay as the encoded text in the output. But just because I have never done it that way so what. You may need to force this line to be text output. Look at the processing instruction:
<xsl:text>Most any data here.
There are limits to this also but it is what I have used most often. I also use the output instructions to not have any text output that is not explicit such as this line:
<xsl:output method="text" encoding="utf-8" media-type="model/vrml" indent="no" cdata-section-elements="Script">
I do this so as to not pickup extra linefeeds etc.

I think there's quite a bit of XML data your missing from your output, remember to substitute < and > in the right places.
Besides that, replacing it with < and > didn't work for the !DOCTYPE. It just outputted the actual text of <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Any other ideas?

Yes I did not check the display message as is (no HTML). 
I was just adding the xsl:text tag that essam mentions above. There are also option to not add all of the text (line feeds etc.) to the output.
My Sample lines were approximately:
<xsl:output method="text" encoding="utf-8" media-type="model/vrml" indent="no" cdata-section-elements="Script"/>
<!-- ****** X3D: convert the X3D tag to VRML 3.0 header ****** -->
<xsl:template match="X3D">
<xsl:text>#VRML V2.0 utf8 </xsl:text>
<xsl:text># [X3D] VRML V3.0 utf8 </xsl:text>
<xsl:apply-templates select="Scene"/>
</xsl:template>
This is the begining of my translation file for converting X3D models into VRML97. Lets see if I get it right this time.
There are a number of sites with info here.
One example is the w3schools site
http://www.w3schools.com/xsl/el_text.asp
and zvon
http://www.zvon.org/xxl/XSLTreference/W3C/xslt.html#element-text

This works great! Thank you so much!
But now I've got another question... Should I do the same thing for my <?xml version="1.0" encoding="utf-8"?> that I want at the very top of the output document, or will this be done for me? From what I've seen using XSL Tester to view my XHTML output, this is done for me, but it gives me an encoding="UTF-16", which I don't think is a valid encoding.
Can I somehow change the way this is generated automatically if it is, or is this simply a quirk in XSL Tester and I should do the same thing Idid with my !DOCTYPE, by putting it in that special <xsl:tex> element?

I assume that you are using one of the MSXML implementations. To set the encoding see the xsl:output transformation element (at the begining of the transformation), You should be able to set utf-8 with it. UTF-16 is a valid encoding. Most of my work right now is with the Apache line of implementations so there may be some variations. I have shown that DOM and SAX transformations do not always give the same results. I do have some test applications with the MSXML v3 and v4 so I can do some experiments if needed.
<xsl:output method="text" encoding="utf-8"/>

I am using the MSXSL that comes with IE6 or the .NET Runtime, whichever is newer (I have both installed).
So XSL will generate an <?xml...?> declaration automagically, which can be controlled by the <xsl:output> element?

I can say that the xml declaration is not allways output. With the output line shown earlier it should never be output. Just add it with the xsl:text line if needed. The output line will set if encoding is utf-8.

So, my XSL should like like this:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0">
<xsl:output encoding="utf-8" />
<xsl:template match="/">
<xsl:text disable-output-escaping="yes">
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
</xsl:text>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US">
<!-- Stuff here -->
</html>
</xsl:template>
</xsl:stylesheet>
And this will output:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US">
<!-- The stuff that was where the comment was goes here -->
</html>
If you're not absolutely sure, could you write me quick program or give me the JScript code (not .NET) to just output the text? Whenever I do a view source in IE, it just gives me the original XML.
I would do that myself, but I'm stuck on this Windows 98 until I get a new hard drive
Thank you!

There are two ways to output the DOCTYPE.
One is using the OUTPUT method in XSL, like so:
>xsl:output method="html" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype-system="DTD/xhtml1-transitional.dtd" indent="yes" /<
The other, is easier but probably not such a good idea. It uses the XSL:TEXT and CDATA section methods:
>xsl:text disable-output-escaping="yes"<>![CDATA[>!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"<]]<>/xsl:text<
This one also baffled me for awhile until I found the OUTPUt method, happy hunting.

The output works GREAT for the !DOCTYPE, and is much preferable to the method I got from above (enclosing it in a <xsl:text disable-output-escaping="yes"> section)
But... I'm still stuck on getting my <?xml...?> into the output, as I am really trying to output XHTML, not HTML as the above <xsl:output> you posted says (and all good XHTML has a <?xml...?> declaration, as it is XML).
Will this automagically appear, with the encoding specified in the <xsl:output> tag? Or do I have to put it in a <xsl:text disable-output-escaping="yes"> tag?
Again, I could figure this all out myself without bugging everyone if someone would just write a program that takes in.xml, and using transform.xsl outputs out.xsl. That's all I need! I have one that is supposed to do this called XSL Tester, but it's rather screwy (always outputting a <?xml version="1.0" encoding="UTF-16"?> at the top, no matter what I do with output or text tags.), and doesn't use the .NET version of MSXML so I'm never sure if that's really what's going to happen. Heck, I could send you the source code if you would compile it!
Thank you for your time and help,

Actually, now I have a working solution, but I'm getting the idea it's bad practice, and wanted to know if it is.
I enclose EVERYTHING in a:
<xsl:text>
<!CDATA[[
<!-- There's a bunch of XHTML here,
including the xml processing instruction and the
DOCTYPE, but it's parsed as simply text. Is
this good practice? Because it's convenient! -->
]]>
</xsl:text>
section. It works, and it's very convienient. Whenever I want to output something using template rules, I simply end if with a ]]></xsl:text>, write the xsl element, then restart it with the <xsl:text><!CDATA[[. But... this just seems kind of wrong... but it works... but it seems wrong... but... so, what do you think?

It works, just like using pantyhose to fix a broken fan-belt in a car works. However as soon as you can you should get a new proper fan-belt, right?
I had a crushing deadline which forced me to use the xsl:text method to output the DOCTYPE.
However what happened was that when a third party tried to programatically query my XSL documents to gather some info for an integration project they failed to get the DOCTYPE. I eventually re-coded my XSL docs to use the output method.
So the answer is; Yes it works but don't do it if you can avoid it. Your XSL docs will be technically better and easier to maintain in the future if you use the proper output method.
