C++ programming assignment

This assignment builds on a previous assignment which is provided in attached zip folder. The previous assignment parses the element names in an XML file and creates Element object names for each of them. The new assignment is to test an XML well-formedness. To accomplish this, the parser and program need to be enhanced to do the following: -Initialize the state of the parser. -Read an XML file containing data on several of your favorite songs. -“Parse” each line as it is read in and pick out element opening tags. -Print information about each tag. -Push tags that are not closed on the same line as their opening tag onto a stack. -When you find a closing tag, check to make sure that it matches the last element on the stack. -If it does, pop the stack. If it does not, print an error message. -Display the stack as it grows and shrinks. WHAT NEEDS TO BE DONE: 1) Begin by declaring all of the parser states you will need in this program. Write a function that will display the parser state at any given moment so that you have it handy during debugging. 2) Initialize an STL vector or stack that will store pointers (references) to Element objects. This stack will hold pointers to elements that have not yet been closed as you move through each line of the file. This vector could simply hold the names of those elements as string objects, but it is more meaningful to store pointers (references) to actual Element objects themselves. 3) Write a function that will display the contents of this vector or stack for testing purposes. Search the web for an elegant and efficient way to do this using iterators. 4) Next, start enhancing your function that reads the XML file. There are a number of things that you will have to add to this file — most importantly information about the parser state — that we will discuss in class. But at this point you can write the main parts of the function: (a) the commands needed to open and close the XML file and read it line-by-line, and (b) a large switch statement that displays information for each of the parser states that you define. 5) The last major step is to write the function that parses each line of data. This is a complex function that has to check for lots of conditions in a series of if / else if / else tests for each state. Note that some tests will need to know the parser’s current state to fully determine what’s going on. Therefore, there are a number of parameters that you must pass into this function, and a number of values besides the parser state that you must return. Also, the order of your tests will be significant. We will discuss these issues further in class. *NOTES*: The output of the program should look very similar if not exactly like the output file included named, "output for new assignment". I am using a different XML file than the one in the output file so the element names and attributes will be different.
