I want to append new records and remove some records from this file in oracle soa

Answer 1

You should not be using XSLT to make this adjustment, you should be using the BPELX functions in an Assign activity.
To append a new record into the list you should be doing the following
bpelx:append
The bpelx:append extension in an assign activity enables a BPEL process to append the contents of one variable, expression, or XML fragment to another variable's contents.
<bpel:assign>
<bpelx:append>
<bpelx:from ... />
<bpelx:to ... />
</bpelx:append>
</bpel:assign>
The following example will show you how to implement this in your example.
<bpel:assign>
<bpelx:append>
<from variable="variableFrom"
query="variableFromQuery" />
<to variable="variableTo"
query="/ns1:Employees/ns1:person" />
</bpelx:append>
</bpel:assign>
To remove this from the queue you should
The bpelx:remove extension in an assign activity enables a BPEL process to remove a variable.
<bpel:assign>
<bpelx:remove>
<bpelx:target variable="variableName" part="Employee" query="query to match node you want to remove" />
</bpelx:remove>
</bpel:assign>
