How to Use XML to Represent Structured Data

Step-by-Step Guide

1. 1

   Step 1: Start off the XML document by writing the XML declaration.

   The XML declaration does not show in the XML document, but the document cannot work without it. , The root element must cover all of the XML document except the declaration, otherwise there will be an error.<case...> </case>
   
   Children are tags contained inside the root element.
   
   Sub-children are inside the children.
   
   The tags on the same level are called siblings.
   
   The tags that are predecessors of any tags are their parent.
   
   The <root> element is the parent of all tags.
   
   Children tags include victim, possiblekiller, date.
   
   There are no sub-children in the example. , Attributes are given like in HTML.
   
   A <tag attribute="value"></tag> works here too.
   
   But as XML is designed to carry information, tags are preferred to attributes.<date> <dd>1</dd> <mm>2</mm> <yyyy>2011</yyyy> </date>
   
   HTML forgives small tag closing mistakes but XML is undeniably brutal in checking the document.
   
   To close a line break tag or an open tag, use a space and a slash(/).<open-tag></open-tag>
   
   <killer> and <killer> are not the same. , Comment formats are the same as in HTML.<!-- This is a comment
   -->
