Parsing XML File in ABAP

Hello,

an existiting abap program receives a XML String over http and it creates a dom structure of it by using .

Now I want to use the same technique for an other xml file, which is formed based on an other xsd file.

When I do sent this to the service the parse_string method returns a value of 1 which is not ok.

The code snippet and the xml file is below.

Do I have to save the xsd File somewher or provide it elsewhere, or what can be the eror here.

my xml Fiel starts with

<epcis:EPCISDocument xmlns:epcis="urn:epcglobal:epcis:xsd:1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" creationDate="2005-07-11T11:30:47.0Z" schemaVersion="1">

Best regards

Michael

data:

        lref_xmldoc         TYPE REF TO cl_xml_document_base,

        lv_retcode          TYPE sysubrc,

CREATE OBJECT lref_xmldoc.
*   parse payload as XML
    lv_retcode = lref_xmldoc->parse_string( stream = lv_cdata ).
    lv_isinitial = lref_xmldoc->is_initial( ).

    IF lv_retcode = lref_xmldoc->c_ok AND
       lv_isinitial IS INITIAL.

      lref_xmlnode = lref_xmldoc->m_document->get_root_element( ).

....

     endif.

here is the xml document.
