ABAP Service: Scanning through HTML

Question

Dear ABAP community,
Iu2019m thinking about a method to scan through HTML code of an specified URL.
The idea is to scan the HTML content by a search term; so I need a function to get the data of the page specified by a URL and scan this page.
Is there any method/function in ABAP?
Thanks for your feedback.
Best regards,
Kurt.

Hello to all,
a colleague of mine found a very good solution to scan a page provided by an appropriated URL:
  data: lv_html   type string,
        lv_url    type string.
* Create client
  call method cl_http_client=>create_by_url
    exporting
      url                = lv_url
    importing
      client             = lv_client
    exceptions
      argument_not_found = 1
      plugin_not_active  = 2
      internal_error     = 3
      others             = 4.
  if sy-subrc ne 0.
    message id sy-msgid type sy-msgty number sy-msgno
      with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  endif.
* Get request:
  call method lv_client->send
    exceptions
      http_communication_failure = 1
      http_invalid_state         = 2
      http_processing_failed     = 3
      others                     = 4.
  if sy-subrc ne 0.
    message id sy-msgid type sy-msgty number sy-msgno
      with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  endif.
* Prepare client-receive:
  lv_client->receive( exceptions others = 1 ).
* Get HTML:
  lv_html = lv_client->response->get_cdata( ).
* Sesrch for a string in HTML:
  if not pa_find is initial.
    find first occurrence of pa_find in lv_html in character mode ignoring case.
    if sy-subrc eq 0.
    endif.
  endif.
Best regards,
Kurt.
