[xsl] Move leading/trailing spaces outside (XSLT 2.0)

[Yves Forkl <Y.Forkl@xxxxxx>]

Hi,

I'm looking for an elegant XSLT 2.0 solution to this tiny problem. When 
processing

<e> one</e>
<e>two </e>
<e> three </e>

I want to separate the leading and trailing spaces from the rest of the 
content but keep them in the output as text nodes, like if I was saying 
in XSLT

<xsl:text> </xsl:text><e>one</e>
<e>two</e><xsl:text> </xsl:text>
<xsl:text> </xsl:text><e>three</e><xsl:text> </xsl:text>

normalize-space() won't tell me how much spaces it removed, and there 
must be a less awkward way than using xsl:choose with 3 clauses...

Any suggestions? Should I try with tokenize() or matches()?
