Examples

Extracting the Translation from an XMLTYPE

Let doc =

<securityClass xmlns="http://xmlns.oracle.com/xdb/security.xsd"
               xmlns:is="xmlns.oracle.com/iStore"
               xmlns:oa="xmlns.oracle.com/OracleApps"
               targetNamespace="xmlns.oracle.com/example">
    <name>
        securityClassExample
    </name>
    <title xml:lang="en" xdb:srclang="true">
        Security Class Example
    </title>
    <title xml:lang="fr">
        Security Class Example - FR
    </title>
    <title xml:lang="es">
        Security Class Example - ES
    </title>
    <inherits-from>is:iStorePurchaseOrder</inherits-from>
</securityClass>

Let the xpath = '/securityClass/title'. The output of EXTRACTXLIFF will be as follows:

<xliff version='1.1'>
  <file original='' source-language='en' datatype='xml'>
    <body>
      <trans-unit id='/securityClass/title'>
        <source>Security Class Example</source>
        <alt-trans>
          <target xml:lang='fr'>Security Class Example - FR</target>
          <target xml:lang='es'>Security Class Example - ES</target>
        </alt-trans>
      </trans-unit>
    </body>
  </file>
</xliff>

Extracting the Translation from a Resource

Let the resource '/public/security.xml' =

<securityClass xmlns="http://xmlns.oracle.com/xdb/security.xsd"
               xmlns:is="xmlns.oracle.com/iStore"
               xmlns:oa="xmlns.oracle.com/OracleApps"
               targetNamespace="xmlns.oracle.com/example">
    <name>
        securityClassExample
    </name>
    <title xml:lang="en" xdb:srclang="true">
        Security Class Example
    </title>
    <title xml:lang="es">
        Security Class Example - ES
    </title>
    <title xml:lang="fr">
        Security Class Example - FR
    </title>
    <inherits-from>is:iStorePurchaseOrder</inherits-from>
    <privlist>
    <privilege name="privilege1"/>
    <aggregatePrivilege name="iStorePOApprover">
        <title>
            iStore Purchase Order Approver
        </title>
        <privilegeRef name="is:privilege1"/>
        <privilegeRef name="oa:submitPO"/>
        <privilegeRef name="oa:privilege3"/>
    </aggregatePrivilege>
    <privilege name="privilege2">
        <title xml:lang="en">
            secondary privilege
        </title>
        <title xml:lang="fr" xdb:srclang="true">
            secondary privilege - FR
        </title>
        <columnRef schema="APPS" table="PurchaseOrder" column="POId"/>
        <columnRef schema="APPS" table="PurchaseOrder" column="Amount"/>
    </privilege>
    </privlist>
</securityClass>

And let XPATH = '', then the extracted XLIFF is

<xliff version='1.1'>
  <file original='/public/security.xml' source-language='en' datatype='xml'>
    <body>
      <trans-unit id='/securityClass/title'>
        <source>Security Class Example</source>
        <alt-trans>
          <target xml:lang='fr'>Security Class Example - FR</target>
          <target xml:lang='es'>Security Class Example - ES</target>
        </alt-trans>
      </trans-unit>
    </body>
  </file>
  <file original='/public/security.xml' source-language='fr' datatype='xml'>
    <body>
      <trans-unit id='/securityClass/privilege[@name="privilege2"/title'>
        <source>secondary privilege - FR</source>
        <alt-trans>
          <target xml:lang='en'>secondary privilege</target>
        </alt-trans>
      </trans-unit>
    </body>
  </file>
</xliff>

GETBASEDOCUMENT Function

This function returns the base document with all the translations.

Syntax

DBMS_XMLTRANSLATIONS.GETBASEDOCUMENT(
   doc    IN  XMLTYPE)
 RETURN XMLTYPE;

Parameters

        <columnRef schema="APPS" table="PurchaseOrder" column="Amount"/>
    </privilege>
    </privlist>
</securityClass>

Let the input XLIFF be as follows:

<xliff version='1.1'>
  <file original='/public/security.xml' source-language='en' datatype='xml'>
    <body>
      <trans-unit id='/securityClass/title'>
        <source>Security Class Example Modified</source>
        <alt-trans>
          <target xml:lang='fr'>Security Class Example Mod - FR</target>

    <inherits-from>is:iStorePurchaseOrder</inherits-from>
    <privlist>
    <privilege name="privilege1"/>
    <aggregatePrivilege name="iStorePOApprover">
        <title>
            iStore Purchase Order Approver
        </title>
        <privilegeRef name="is:privilege1"/>
        <privilegeRef name="oa:submitPO"/>
        <privilegeRef name="oa:privilege3"/>
    </aggregatePrivilege>
    <privilege name="privilege2">
        <title xml:lang="en" xdb:srclang="true">
            secondary privilege modified
        </title>
        <title xml:lang="fr">
