I don't know whether I got you right: your expected output assumes you
want all contacts with different Nids and if Nids are the same you want
the latest. If so this should work:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">
<xsl:output method="xml" encoding="UTF-8"/>
<xsl:template match="/objects">
<xsl:copy>
<xsl:for-each-group select="Contact" group-by="Nid">
<xsl:sort select="Nid"/>
<xsl:sort select="LastModifiedDate" order="descending"/>
<xsl:copy-of select="."/>
</xsl:for-each-group>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
This also sorts by Nid - just for the heck of it. :)

I have only one XML. and there <Nid> contains same data like 892828740. I
want get the Id,LastModifiedDate,Nid for Contact based on updated
LastModifiedDate if <Nid> has more then one same kind of data. Below is my
Input data, XSL, expected output. But my code is not working fine
Below is XML:
<?xml version="1.0" encoding="UTF-8"?>
<objects>
<Contact>
<Id>003j000001DQMkcAAH</Id>
<LastModifiedDate>2016-09-08T10:31:24.000Z</LastModifiedDate>
<Nid>892828740</Nid>
</Contact>
<Contact>
<Id>003j000001DQMlXAAX</Id>
<LastModifiedDate>2016-09-08T10:22:47.000Z</LastModifiedDate>
<Nid>879284114</Nid>
</Contact>
<Contact>
<Id>003j000001DQMlYAAX</Id>
<LastModifiedDate>2016-09-08T10:22:47.000Z</LastModifiedDate>
<Nid>882692370</Nid>
</Contact>
<Contact>
<Id>003j000001DQMlZAAX</Id>
<LastModifiedDate>2016-09-08T10:22:47.000Z</LastModifiedDate>
<Nid>892828740</Nid>
</Contact>
</objects>
Below in XSL:
<xsl:stylesheet version="2.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="objects">
<xsl:if test="count(//Contact/Nid[(. =
../following-sibling::Contact/Nid)])">
<Nids>
<Nid>
<Id>
<xsl:value-of
select="//Contact/Nid[(. =
../following-sibling::Contact/Nid)]"/>
</Id>
<LastModifiedDate>
<xsl:value-of select="//LastModifiedDate"/>
</LastModifiedDate>
<Nid/>
</Nid>
</Nids>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
Expected output:
<objects>
<Contact>
<Id>003j000001DQMkcAAH</Id>
<LastModifiedDate>2016-09-08T10:31:24.000Z</LastModifiedDate>
<Nid>892828740</Nid>
