Scrape data from Apex which created with PL/SQL dynamic content? - html

Question

I have used PL/SQL dynamic content for creating a report. I need to add functionality to scrape (take data) from this HTML. Moreover, I have SQL which returns data.
How can I do this with APEX region PL/SQL dynamic content?
PL/SQL code for creating HTML tags with data:
declare
l_sql varchar2(2000) := test.function(92500, 2017, 2, 114); --return which select when we dynamical execute this select it will return data
l_columns varchar2(2000) := test.test_function_dynamic_columns_name(92500, 2017, 2, 114);
l_vc_arr2 APEX_APPLICATION_GLOBAL.VC_ARR2;
v_tableclob clob := '<table summary="" class="a-IRR-table" id="2212903112260009" role="presentation">';
v_rowclob clob;
v_rowclob_1 clob;
begin
l_vc_arr2 := APEX_UTIL.STRING_TO_TABLE(l_columns);
v_tableclob := v_tableclob||'<tr>';
v_tableclob := v_tableclob ||'<th class="a-IRR-header">';
v_tableclob := v_tableclob ||REPLACE(REPLACE(l_columns,'"',' '),':','</th><th class="a-IRR-header">');
v_tableclob := v_tableclob ||'</th></tr>';
FOR z IN 1..l_vc_arr2.count LOOP
if l_vc_arr2(z) = '"SUM"' then
v_rowclob := v_rowclob ||'<td class="summation">''||t.'||l_vc_arr2(z)||'||''</td>';
v_rowclob_1 := v_rowclob_1 || '<td id="total_sum"></td>';
else
v_rowclob := v_rowclob ||'<td>''||t.'||l_vc_arr2(z)||'||''</td>';
v_rowclob_1 := v_rowclob_1 || '<td></td>';
end if;
end loop;
execute immediate
'
declare
begin
htp.p('''||v_tableclob||''');
for t in ('||l_sql||') loop
htp.p(''<tr>'||v_rowclob||'</tr>'');
end loop;
htp.p(''<tr>'');
htp.p('''|| v_rowclob_1 ||''');
htp.p(''</tr>'');
htp.p(''</table>'');
end;';
end;
