Hi Sola,
You didn't show your full code and you didn't tell what processor you
are using and what XSLT version. If you specifiy "number" for the
data-type, then the content is converted to a numeric value. This
includes the minus sign.
Note that your data is illegal XML as where legal XML it is not allowed
to have any element starting with xml, XML or any combination of case,
see http://www.w3.org/TR/xml/#IDAKKFS. However, most XML processors dig
it anyway ;)
I tried the following stylesheet and ran it with Saxon 8. It gives the
result you want:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes" />
<xsl:template match="/xml">
<xsl:apply-templates select="data">
<xsl:sort select="." data-type="number" />
</xsl:apply-templates>
</xsl:template>
<xsl:template match="data">
<xsl:text> </xsl:text>
<xsl:value-of select="text()"/>
</xsl:template>
</xsl:stylesheet>
If this does not work with your processor, it is likely a bug.
Good luck with it,
Cheers,

Hi,
Can anyone tell why the code below will not work?
<xsl:sort select="data" data-type="number"/>
I am trying to sort numeric data that contains negative values but the
order seems to be wrong
<xml>
<data>22</data>
<data>2</data>
<data>-5</data>
<data>42</data>
<data>0</data>
<data>-1</data>
<data>0</data>
</xml>
This is the output
0
-1
0
-5
2
22
42
I want
-5
-1
0
0
2
22
42
