Pieter,

There is a utility called msxsl.exe that can be used to strip or preserve
whitespace (it's not a new tool, and works as a wrapper for MSXML 3 and 4):

msxsl.asp
Check for the -xw option:
"White Space Stripping (-xw Option)
The -xw option instructs MSXSL to strip non-significant white space from the
input XML document during the load phase (preserveWhitespace set to False).
Enabling this option can lower memory usage and improve transformation
performance while, in most cases, creating equivalent output."
Thanks for posting the reminder: it's nice to be able to run MSXSL and get
proper results.
Do you know of any way of disabling the option when just opening XML
natively in IE, with an xml-stylesheet PI?
Personally, in some cases, I don't see a problem in stripping the white
space; in fact, in the HTML world, stripping white space can even optimize
the way browsers renders a given page. Extra whitespace between elements
(and carriage returns) can introduce differences at the pixel render
position level.
It's the "in some cases" that bites. It's really terrible to see HTML come
out like
<p>Here's my <b>extra</b><i>special</i> HTML page</p>
... because the space that was there (between the elements rendered as b
and i) happens to be treated like a case where we wouldn't see a problem.
That's why we prefer to use long one-liners without
whitespace and CRs - ugly, but necessary.
Whitespace control in the stylesheet, as Mike just reminded us, is an
entirely different thing. Providing you use <xsl:text> and <xsl:output>
properly, you can use all the whitespace you like, in the stylesheet,
without getting any extra space in the output.
Cheers,
Wendell
