generalized unique element

hello
is it possible to output unique nodes in general from an xml file..

<university-records>
	<univ-ids>
		<univ id = "KSU">
			<name>Kansas State University</name>
			<location>Kansas</location>
		</univ>
		<univ id = "FAU">
			<name>Florida Atlantic University</name>
			<location>Florida</location>
		</univ>
		<univ id = "MSU">
			<name> Mississipi State University</name>
			<location> Mississipi </location>
		</univ>
		<univ id = "OSU">
			<name>Ohio State University</name>
			<location> Ohio </location>
		</univ>
	</univ-ids>
	<university-results>
		<university univ-id = "KSU">100%</university>
		<university univ-id = "MSU">90%</university>
		<university univ-id = "FAU">80%</university>
	</university-results>
</university-records>

<university-records>
	<univ-ids id = "">
		<univ></univ>
	</univ-ids>
	<university-results>
		<university univ-id = ""></university>
	</university-results>
</university-records>

any ideas?
Thanks

The following XSL would do:
(though I was not able to filter the redundant universities under univ-ids. your output is similar to the one I get using this xsl file)

<?xml version="1.0"?>
<xsl:stylesheet version='1.0'
				xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
<xsl:output method="xml" indent='yes'/>

<xsl:param name="univ2" select="'./univ2.xml'"/>
<xsl:param name="univ3" select="'./univ3.xml'"/>

<xsl:template match="/">
	<xsl:copy>
		<xsl:apply-templates select="*"/>
	</xsl:copy>
</xsl:template>

<xsl:template match="university-records">
	<xsl:copy>
		<xsl:for-each select="@*">
			<xsl:copy><xsl:value-of select="."/></xsl:copy>
		</xsl:for-each>
		<xsl:apply-templates select="*"/>
	</xsl:copy>
</xsl:template>

<xsl:template match="univ-ids">
	<xsl:copy>
		<xsl:for-each select="@*">
			<xsl:copy><xsl:value-of select="."/></xsl:copy>
		</xsl:for-each>
		<xsl:apply-templates select="univ"/>
		<xsl:copy-of select="document($univ2)//univ-ids/univ/@id[.='OSU']"/>
		<xsl:copy-of select="document($univ3)//univ-ids/*"/>
		<xsl:apply-templates select="university-results"/>
	</xsl:copy>
</xsl:template>

<xsl:template match="univ">
	<xsl:copy-of select="."/>
</xsl:template>

<xsl:template match="university-results">
	<xsl:copy>
		<xsl:for-each select="@*">
			<xsl:copy><xsl:value-of select="."/></xsl:copy>
		</xsl:for-each>
	<xsl:apply-templates select="university"/>
	<xsl:copy-of select="document($univ2)//university-results/*"/>
	<xsl:copy-of select="document($univ3)//university-results/*"/>
	</xsl:copy>
</xsl:template>

<xsl:template match="university">
	<xsl:copy-of select="."/>
</xsl:template>

</xsl:stylesheet>

i have got a fairly conplicated problem ( atleast for me :( )
i have got 3 xml files that contains university result data from 3 different regions.and i have to merge them into one xml with all the data from 3 xmls. The resultant XML should have the same structure as individual XMLs.
for example,
xml1:
<?xml version="1.0"?>
<university-records>
<univ-ids>
<univ id = "KSU">
<name>Kansas State University</name>
<location>Kansas<location>
</univ>
<univ id = "FAU">
<name>Florida Atlantic University</name>
<location>Florida<location>
</univ>
<univ id = "MSU">
<name> Mississipi State University</name>
<location> Mississipi <location>
</univ>
<univ id = "OSU">
<name>Ohio State University</name>
<location> Ohio <location>
</univ>
</univ-ids>
<university-results>
<university univ-id = "KSU">100%</university>
<university univ-id = "MSU">90%</university>
<university univ-id = "FAU">80%</university>
</university-results>
</university-records>

xml2:
<?xml version="1.0"?>
<university-records>
<univ-ids>
	<univ id = "OSU">
		<name> Ohio State University</name>
		<location> Ohio <location>
	</univ>
	<univ id = "WSU">
		<name> Wisconsin state University</name>
		<location> Wisconsin <location>
	</univ>
	<univ id = "RPI">
		<name> Rensellar polytechnic Institute </name>
		<location> New Jersey <location>
	</univ>
	<univ id = "MSU">
		<name> Mississipi State University</name>
		<location> Mississipi  <location>
	</univ>
</univ-ids>
<university-results>
	<university univ-id = "OSU">70%</university>
	<university univ-id = "WSU">100%</university>
	<university univ-id = "RPI">100%</university>
</university-results>
</university-records>
xml3:
<?xml version="1.0"?>
<university-records>
<univ-ids>
	<univ id = "NSU">
		<name> Newyork State University</name>
		<location> Newyork <location>
	</univ>
	<univ id = "BU">
		<name> Belmont University</name>
		<location> Belmont <location>
	</univ>
	<univ id = "WSU">
		<name>Wisconsin state University</name>
		<location> Wisconsin <location>
	</univ>
	<univ id = "BCM">
		<name> Berklee College of Music</name>
		<location> Berklee <location>
	</univ>
</univ-ids>
<university-results>
	<university univ-id = "NU">70%</university>
	<university univ-id = "BU">60%</university>
	<university univ-id = "BCM">100%</university>
</university-results>
</university-records>

i want the resultant xml to be ...

<university-records>
<univ-ids>

	<univ id = "KSU">
		<name>Kansas State University</name>
		<location>Kansas<location>
	</univ>
	<univ id = "FAU">
		<name>Florida Atlantic University</name>
		<location>Florida<location>
	</univ>
	<univ id = "MSU">
		<name> Mississipi State University</name>
		<location> Mississipi <location>
	</univ>
	<univ id = "OSU">
		<name> Ohio State University</name>
		<location> Ohio <location>
	</univ>
	<univ id = "OSU">
		<name> Ohio State University</name>
		<location> Ohio <location>
	</univ>
	<univ id = "WSU">
		<name> Wisconsin state University</name>
		<location> Wisconsin <location>
	</univ>
	<univ id = "RPI">
		<name> Rensellar polytechnic Institute </name>
		<location> New Jersey <location>
	</univ>
	<univ id = "MSU">
		<name> Mississipi State University</name>
		<location> Mississipi  <location>
	</univ>
	<univ id = "NSU">
		<name> Newyork State University</name>
		<location> Newyork <location>
	</univ>
	<univ id = "BU">
		<name> Belmont University</name>
		<location> Belmont <location>
	</univ>
	<univ id = "WSU">
		<name>Wisconsin state University</name>
		<location> Wisconsin <location>
	</univ>
	<univ id = "BCM">
		<name> Berklee College of Music</name>
		<location> Berklee <location>
	</univ>

</univ-ids>
<university-results>
	<university univ-id = "NU">70%</university>
	<university univ-id = "BU">60%</university>
	<university univ-id = "BCM">100%</university>
	<university univ-id = "OSU">70%</university>
	<university univ-id = "WSU">100%</university>
	<university univ-id = "RPI">100%</university>
	<university univ-id = "KSU">100%</university>
	<university univ-id = "MSU">90%</university>
	<university univ-id = "FAU">80%</university>
</university-results>
</university-records>

Things to be noticed here: The <univ-ids> in each of the xml files have some <univ-id> elements which are there in other xmls as well. for example the
<univ id = "MSU">
<name> Mississipi State University</name>
<location> Mississipi <location>
</univ>
which is in the xml2
similarly..
<univ id = "OSU">
<name> Ohio State University</name>
<location> Ohio <location>
</univ>
is there in both the xml files..

But The final XML should not reflect this.

Any Ideas as to how we can acheive this??

Thanks in advance..
laura
