We will examine two things: the main APIs and strategies for parsing and manipulating XML in your C application, and the practical uses and tradeoffs of approaches to XML parsing.To get the most from this article, a basic understanding of the C language is required.one parser could use an STL list of strings, while another could use a specially made class to hold attributes and values.The methods for handling a start-element tag with each approach would be very different and would certainly affect how you program them.
