Unable to parse the CDATA section in the input XML file.

   string result;

There are probably better ways with regex, but I'm not able to advise you on that.

Thank you lastchance for the reply.

I have implemented the below solution on similar line you have mentioned above.
Please have a look:

Traverse DOM tree till tag matches to the Parent Tag.
Then check for the children is of CDATA_SECTION_NODE

if(currentNode->getNodeType && if(currentNode->getNodeType == DOMNode:: CDATA_SECTION_NODE)
{
   DOMCharacterData* obj = (DOMCharacterData*) currentNode;
   const XMLCh* chardata = obj->getData();
   char* value = XMLString::transcode(chardata); 
   string x = value;
   int pos = c.find(tagname);
   
   // run a loop for multiple value with same tag
   while(pos > -1)
   {
      string tagValue;
      int posEnd = x.find("</TagName>", pos);
      int diff = posEnd - pos;
      tagValue = x.substr(pos, diff);

      // Update pos
      pos = x.find(tagName, posEnd);
   }
}
