sorting xml source

Hi,

I am a total newbie. I am using this section of xsl.

###
<xsl:for-each select="Cabinate/Print/item">
<tr>
<td style="COLOR: blue; FONT-FAMILY: Arial; FONT-SIZE: 8pt; FONT-WEIGHT:
700">
   <xsl:value-of select="Group"></xsl:value-of> \
   <xsl:value-of select="Name"></xsl:value-of> \
   <xsl:value-of select="Draw"></xsl:value-of> \
   <xsl:value-of select="Folder"></xsl:value-of> \
 page: <xsl:value-of select="currentPage"></xsl:value-of> to <xsl:value-of
select="toPage"></xsl:value-of>
</tr>
</xsl:for-each>
###

Is there any way to sort the xml source say by "Group". Would sorting affect
my orignal xml source in anyway.

TP.
