I apologize for confusing myself and misleading everyone.  I tried to strip
an example down to a minimum.  In stripping it down, I went too far and
forgot that the problem usually comes, not in whitespace-only nodes (as
you're pointing out) , but when you introduce newlines for visual formatting
of the xslt, but don't really want them in the output.  Sort of the inverse
situation, really, but it comes up just often enough to be worth handling
quickly.

Here's an illustration, sort of contrived but gives the idea.

Source file:

<root>
 <xxx>XXX</xxx>
 <yyy>YYY</yyy>
</root>

Stylesheet 1:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" />
<xsl:template match="/root">
 function <xsl:value-of select='xxx'/>(){
  <xsl:value-of select='yyy'/>
 }
</xsl:template>
</xsl:stylesheet>

Output (screen capture from command line):

        function XXX(){
                YYY
        }

Stylesheet 2:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" />
<xsl:template match="/root">
 function <xsl:value-of select='xxx'
  />(){<xsl:value-of select='yyy'/>
 }
</xsl:template>
</xsl:stylesheet>

Output:

        function XXX(){YYY
        }

Of course, it wouldn't  matter for this bit of javascript, but it often
does.

Cheers,
