How Do I get a particular element in the XML I receive (From a third Party)?

Question

I have a XML response which I have received as output of a System link(Infor XA related)process. The response would look like below:

 **<?xml version="1.0" encoding="UTF-8"?>
    -<System-Link hostVersion="1.0" version="1.0">
    -<Response hasWarnings="false" hasErrors="true" systemTimeZoneOffset="-5:00" 
    systemTimestamp="2017-08-22 03:37:01.115" 
    workHandle="-1e4c99eb:15dff5e8e61:-796d" 
    sessionHandle="-1e4c99eb:15dff5e8e61:-7970">
    -<UpdateResponse actionSucceeded="false" 
    requestedDomainClass="com.mapics.epdm.BillOfMaterialComponent" 
    name="updateObject_BillofMaterial Component_1">
    -<Exception name="com.pjx.eScript.ObjectNotFoundException">
    -<Text>
    <![CDATA[Object does not exist]]>
    </Text>
    -<Message type="error">
    -<Text>
    <![CDATA[The named object was not found.]]>  
    </Text>
    </Message>
    </Exception>
    </UpdateResponse>
    <UpdateResponse actionSucceeded="true" 
    requestedDomainClass="com.mapics.epdm.BillOfMaterialComponent" 
    name="updateObject_BillofMaterial Component_2"/>
    <UpdateResponse actionSucceeded="true" 
    requestedDomainClass="com.mapics.epdm.BillOfMaterialComponent" 
    name="updateObject_BillofMaterial Component_3"/>
    <UpdateResponse actionSucceeded="true" 
    requestedDomainClass="com.mapics.epdm.BillOfMaterialComponent" 
    name="updateObject_BillofMaterial Component_4"/>
    <UpdateResponse actionSucceeded="true" 
    requestedDomainClass="com.mapics.epdm.BillOfMaterialComponent" 
    name="updateObject_BillofMaterial Component_5"/>
    </Response>
    </System-Link>**

So I need to get the 'actionSucceeded' value of all the responses(Which would be on one transaction). If it is false, then I would like to get the . Is there a RPG XML function to get this? Basically I need to know if my request was success or not by checking the response(as shown above) and not doing a Scan through the entire request

Use the opcode XML-SAX to parse the xml document. See the IBM Knowledge Center for more info on the opcode, https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_73/rzasd/zzxmlsa.htm .

I use XML-SAX to parse an xml document (configuration file) in one of my projects, see BlueDroplet XML Configuration Provider .

And my opinion: Don't use Java for anything you can easily also do in RPG when your main code base is already RPG.
