How can we display dynamic fields from a XML CLOB?

Question

Jdeveloper Version : 11.1.1.4.0 (11g)
We are calling a database package.procedure from a page VO and it returns a result set. The result set is mainly a XML CLOB. Within XML CLOB, we have various sections which we need to parse and display those on JSF page. Couple of sections within XML are having dynamic fields which means the number of fields returned under that section may change depending upon data conditions. We need to find technical way of displaying those dynamic fields (field name and its data – both are part of XML).
Please suggest how can this be achieved.
Thanks
