Lining Up XML Elements for Input

Question

I am transforming an XML document into the proper canonical format for inputting into our Oracle database. I am able to change the attributes into elements. However, when I do so I can't get the new elements to line up in the proper canonical format for insert. Being new, they want to line up flush with the left margin. Is there a way to make them even with the equal level elements?
XSL:
<DCCONTROLS>
<xsl:apply-templates/>
</DCCONTROLS>
</xsl:template>
<xsl:template match="//Geopotential">
<xsl:element name="GEOPOTENTIAL">
<xsl:value-of select="node()"/>
</xsl:element>
<xsl:element name="ZONAL">
<xsl:value-of select="@zonal"/>
</xsl:element>
<xsl:element name="TESSERAL">
<xsl:value-of select="@tesseral"/>
</xsl:element>
</xsl:template>
<xsl:template match="//AtmoModelDrag">
<ATMOMODELDRAG>
<xsl:value-of select="node()"/>
</ATMOMODELDRAG>
</xsl:template>
output XML:
<DCCONTROLS>
<GEOPOTENTIAL>EGM-96</GEOPOTENTIAL>
<ZONAL>36</ZONAL>
<TESSERAL>36</TESSERAL>
<ATMOMODELDRAG>JAC70/MSIS90</ATMOMODELDRAG>
</DCCONTROLS>
As you can see, ZONAL and TESSERAL don't line up properly. I would appreciate any suggestions as I've tried about everything I can think of. Thank you.

The whitespace (i.e. indenting) is unimportant for the canonical format, just the correct nested element structure.
Also, there is no need to use the "//" at the beginning of the match pattern in your <xsl:template> it's already understood that this will match a <Geopotential> element wherever it occurs.
