</line>
<line>
<Date1></Date1>

</line>
</Order>
O/P: earliest Date among all the Date1 nodes and Lease Date among all Date2 nodes in Order tag .
Let me know if any one has worked on similar requirement .

Answer 1

you could use xsl to do this (although it doesn't work one some string dates i tested
see :
http://www.deez.info/sengelha/category/programming/xml/xpath/
Selecting A Maximum Value Using XPath
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
      <xsl:for-each select="/Order/line">
      <xsl:sort select="Date1" order="descending" />
      <xsl:if test="position() = 1">
        <xsl:value-of select="Date1"/>
        </xsl:if>
        <br></br>
      </xsl:for-each>
    <xsl:value-of select="/Order/line[not(preceding-sibling::line/Date1 > Date or following-sibling::line/Date1 > Date)]"/>
</xsl:template>
</xsl:stylesheet>maybe you first need to 'format' the date to some other format so it can do a good sort on it.
maybe the sample helps you a bit
