my xml file format is

<?xml version="1.0" encoding="UTF-8"?>

<entity-mappings xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.eclipse.org/eclipselink/xsds/persistence/ormhttp://www.eclipse.org/eclipselink/xsds/eclipselink_orm_2_4.xsd">

  <entity class="com.ofss.fc.domain.account.entity.accountcreditmatrix.CreditMetricDetails">

    <table name="FLX_AC_ACCT_CREDIT_MATRIX_DTLS"/>

    <attributes>

      <embedded-id attribute-type="com.ofss.fc.domain.account.entity.accountcreditmatrix.CreditMetricDetailsKey" name="key">

        <attribute-override name="accountId">

          <column name="ACCOUNT_ID"/>

        </attribute-override>

        <attribute-override name="accountType">

          <column name="ACCOUNT_TYPE"/>

        </attribute-override>

        <attribute-override name="effectiveDate">

          <column name="EFFECTIVE_DATE"/>

        </attribute-override>

        <attribute-override name="matrixIdvalue">

          <column name="MATRIX_ID_VALUE"/>

        </attribute-override>

        <attribute-override name="classification">

          <column name="Classification"/>

        </attribute-override>

      </embedded-id>

I would like to print attribute-override and column value.

I have tried

String expression = "/entity-mappings/entity/table/@name"; 

it works fine

output FLX_AC_ACCT_CREDIT_MATRIX_DTLS

if I go a level down

String expression = "/entity-mappings/entity/table/attributes/embedded-id/attribute-override/@name";  

it does print the value of attribute-override

please can I know the issue

thanks.
