Question

 I am trying to create a program called parseXml for parsing an XML file, which is a file containing XML tags and text. The tags are used to mark up the structure of the data represented in the file. Here is the algorithm that I have put together but I am having trouble trying to create just the empty tag name stack, which is the first line. What would you suggest I do for starters? 

 create an empty tag name stack 

 set indent level to 0 

 for each token {   if (the token is an opening tag) {     print indenting according to indent level     print token     push tag name onto the tag name stack     increase indent level
