Hello Soufiène,

You can make use of the class CL_XML_DOCUMENT to read the value in the XML tags:

DATA: v_str TYPE string.

v_str = '<boolean xmlns="http://www.webservice.net">true</boolean>'.

DATA:
      lcl_xml_doc TYPE REF TO cl_xml_document,
      v_subrc TYPE sysubrc,
      v_node TYPE REF TO if_ixml_node,
      v_iterator TYPE REF TO if_ixml_node_iterator,
      v_node_value TYPE string,
      v_seqnc TYPE i.

* Create an instance of the class CL_XML_DOCUMENT
CREATE OBJECT lcl_xml_doc.

*  Send XML to method parse_string from class cl_xml_document
v_subrc = lcl_xml_doc->parse_string( v_str ).

* Get the instance of the XML document
v_node = lcl_xml_doc->m_document.

CHECK NOT v_node IS INITIAL.

* Get the instance of the XML iterator
v_iterator = v_node->create_iterator( ).

* Get the next XML Node
v_node = v_iterator->get_next( ).

CLEAR v_seqnc.

WHILE NOT v_node IS INITIAL.

  CASE v_node->get_type( ).
    WHEN if_ixml_node=>co_node_text OR
      if_ixml_node=>co_node_cdata_section. "Node Text
      v_node_value = v_node->get_value( ).
  ENDCASE.

  v_node = v_iterator->get_next( ).

ENDWHILE.

WRITE: v_node_value.

Hope this helps.

BR,

Suhas
