Paper Title
Development of Web Services Based on XML Language and Concerning the Soap Protocol

Abstract
This research paper on the topic: of "Development of WEB Services Based on XML Language and Concerning the SOAP Protocol" will explore: what is the main purpose of the SOAP protocol, its shortcomings of the SOAP protocol, whether there are security vulnerabilities within the SOAP protocol and security options. In addition to the research part, the paper will also use a scientific method of content analysis based on which certain definitions of WEB services will be given, such as (1) XML, (2) AJAX, (3) SOAP and (4) REST. The research will be conducted on respondents (sample) belonging to the group of web developers (in terms of collecting relevant information). Also, in theory, the following will be explained in detail: (1) web services and (2) protocols such as (1) AJAX protocols, (2) SOAP protocols, and (3) REST state transfers. In addition to the mentioned protocols and XML as an extensible language for tagging data and documents, formats such as (1) HTML 5.3 and (2) JSON open standards for formatting data when transferring between applications are also an indispensable part of the web service, as for the scientific practice of “FlexSim” 3D Simulation Modelling and Analysis Software usage (https://www.flexsim.com/) with aims to analyse and assess the possibility of applying intelligent transport systems, i.e. advanced digital technologies in road traffic to increase traffic flow, safety and comfort.
