So let's begin by opening the xmlparsing_start file.…And the first thing I'm going to do is import the module…that lets me operate on an XML DOM.…So I'll write import xml.dom.minidom.…So the XML file I'm going to be parsing,…is this one over here named samplexml.xml.…So if you open it up and look at it,…you can see it's a pretty standard XML file.…It's just got some basic information about a person in it,…
