Hi Georg,
A couple of things:
I'm unsure of why you are normalizing the spaces after converting CRs
and tabs to spaces, and stripping line feeds, with translate() (in
two separate operations). Why not simply normalize the spaces, since
that takes care of line feeds and tabs? (The parser should already
have normalized CRs away so they shouldn't even be there.)
More basically, and this is what accounts for your problem: you are
matching elements, creating new elements with the same names (any
reason not to use the simpler xsl:copy instruction?), writing out
their string values (i.e. all the text inside the elements) and then
descending the tree to do the same. This results in your string
values being written out over and over again, every time an ancestor
element gets processed.
So if your input were
<greeting>
<to>Georg</to>
<from>XSL-List</from>
<text>Hey, how are tricks?</text>
</greeting>
you'll get
<greeting>GeorgXSL-ListHey, how are tricks?
<to>Georg</to>
<from>XSL-List</from>
<text>Hey, how are tricks?</text>
</greeting>
since the greeting element gets its text value copied before its own
element contents are traversed.
Instead of this, you only want to normalize values of the *text*
nodes, letting element nodes take care of themselves ... so:
<xsl:template match="text()"/>
<xsl:value-of select="normalize-space()"/>
</xsl:template>
<xsl:template match="*">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
... as you can see, fairly simple, and a garden-variety near-identity
transform.
Cheers,
Wendell

Hello,
i have a xml file with some content in it which contains some unwanted
carriage returns and whitespaces. Now I'm trying to write a stylesheet
which makes an exact copy of the source file but without the returns
and whitespaces. I thought this should work:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output name="stripped" method="xml" version="1.0"
encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<xsl:result-document format="stripped" href="result.xml">
<xsl:apply-templates/>
</xsl:result-document>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{name()}">
<xsl:value-of select="normalize-space(translate(translate(.,
'
', ' '), '	', ' '))"/>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
But the output is a mess in parts. What am I doing wrong?
