To preserve text node and element sequence and tags use <xsl:copy-of 
select="" />
A reference on copy-of is here: http://www.w3schools.com/xsl/el_copy-of.asp.

To upper case the text, you may have to parse through the nodes with 
generic templates:

<xsl:template match="node()">
   <xsl:variable name="EltName" select="name()" />
   <xsl:element name="{$EltName}">
     <xsl:value-of select="upper-case(.)" />
   </xsl:element>
</xsl:template>


<xsl:template match="text()">
   <xsl:value-of select="upper-case(.)"/>
</xsl:template>

The select from the parent would be something like this
<xsl:apply-templates select="node()" />
