Summary

Today, you took a look at how to create XML documents in general. You saw various ways of writing XML to files, and worked with a few XML editors.

You also took a look at the parts of an XML document—XML prologs, XML declarations, comments, processing instructions, comments, processing instructions, elements, CDATA sections, and entities. You're going to get more familiar with all these items in the days to come.

You can use XML validators to check your XML documents, and there are a number of free ones online. However, you need a way of specifying how that document's syntax is supposed to work, such as a Document Type Definition (DTD) or XML schema.

Most of today's work centered around the creation of XML documents and what's legal to put in them and what's not. You'll see more details in the Days to come, but we've gotten a good foundation here.
