That is output I'm looking is 102888(102 is sno of Tamil and 888 is for Ravi).

SELECT xmltype('<class>
<student>
<name>Raju</name>
<sno>101</sno>
</student>
<student>
<name>Tamil</name>
<sno>102</sno>
</student>
<student>
<name>Ravi</name>
<sno>888</sno>
</student>
</class>') result1,'111' keyid
FROM dual
union all
SELECT xmltype('<class>

</student>
<student>

<sno>208</sno>
</student>
</class>') result1,'222' keyid FROM dual
