Need help in xslt transformation

Hi

I have one input xml file
<param name="EXTR_COL" valueDesc="AUTHD_RFLL" value="rx.AUTHD_RFLL" />
There is a mapping parameters in Database.

if EXTR_COL is present in input XML then it is mapped to fieldlist.

so the o/p XML looks like

 &lt;fieldlist&gt;
&lt;datasource name="Oracle database" value=""&gt;
  &lt;schemaname value="schema"&gt;
    &lt;table value="tablename" dbobjtype="table"&gt;

<field value="AUTHD_RFLL" calcid="0" dbobjtype="field" datatype="varchar2" datasize="9" precision="0" not_null="true">

I want to know how we can do this transformation.

Double post. Need help for xslt transformation using Shell script
