[xsl] RE: A whitespace question, but probably not the same as the other ones

["Nice, Kerry A. (LNG-SHEP)" <Kerry dot Nice at LexisNexis dot com>]

Ok, good call.  I had forgotten I set:
        parser.setFeature(
"http://apache.org/xml/features/dom/include-ignorable-whitespace";,
                               false );  
to fix another problem.  Now I need to figure out how to fix those other
problems.  But the ones I've tried so far I seem to be able to control with
normalize-space().  I tried so many different things, I lost track of what I
tried.  I guess if the whitespace wasn't there in the first place, nothing I
did in the stylesheet would matter.

Another possible cause is that two normalised values are concatenated, and
the
ending white space of the first one and the starting whitespace of the
second one
were eliminated. this can happen like in the following example:

<x>
    <a> Some text </a>
    <b> Some more text </b>
</x>

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
    <xsl:output method="text" />

    <xsl:template match="x/*">
        <xsl:value-of select="normalize-space()" />
    </xsl:template>
</xsl:stylesheet>

Result:
------
Some textSome more text


To avoid this, reproduce the starting and ending characters of a text node
and
normalise the rest of it.

Or, concatenate text nodes and only then normalize-space() the
concatenation.
