Smooks XML-XML transformation with multiple insertion points - freemarker

Question

I am trying to transform an xml from one format to another using smooks. The source xml looks like what is shown below:
<page>
<responsedata>
<header>
...
<ref_no>xyz</ref_no>
</header>
<detail>
<acc_no>x</acc_no>
<ac_ccy>y</ac_ccy>
<avail_bal>z</avail_bal>
</detail>
<detail>
...
</detail>
</responsedata>
</page>
I am trying to tranform the above to something like this:
<detail>
<ref_no>xyz</ref_no>
<accounts>
<account>
<Account_no>x</Account_no>
<Curr>y</Curr>
<Avail_Bal>z</Avail_Bal>
</account>
<account>
...
</account>
</accounts>
</detail>
For this, I used the following smooks configuration:
<ftl:freemarker applyOnElement="responsedata">
<ftl:template><!--<?xml version="1.0" encoding="UTF-8" ?>
<DETAIL>
<Ref_No>????<Ref_No> //how to bring the ref_no here
<Accounts>
<?TEMPLATE-SPLIT-PI?>
</Accounts>
</DETAIL>
--></ftl:template>
</ftl:freemarker>
<ftl:freemarker applyOnElement="detail">
<ftl:template><!--
<Account>
<Account_no>${detail.acc_no}</Account_no>
<Curr>${detail.ac_ccy}</Curr>
<Avail_Bal>${detail.avail_bal}</Avail_Bal>
</Account>
--></ftl:template>
</ftl:freemarker>
Except for the reference number, I am able to transform everything else. Any suggestions on how to accomplish this would be highly appreciated.

Answer 1

Could you use the Smooks javabean capability to bind that value to a Java object (just put in a HashMap) and then access that bean from the Freemarker template?

Answer 2

<resource-config selector="header">
<resource>org.milyn.javabean.BeanPopulator</resource>
<param name="beanId">header</param>
<param name="beanClass">java.util.HashMap</param>
<param name="bindings">
<binding property="refNo" selector="header/ref_no" />
</param>
</resource-config>
<resource-config selector="header">
<resource type="ftl">
<![CDATA[<detail>
<ref-no>${header.refNo}</ref-no>
...
</detail>]]>
</resource>
</resource-config>
