The document body in an XML document is made up of elements that contain data to be stored in the document. Elements are the basic building blocks of XML files. List three important points to remember about XML elements.
What will be an ideal response?
1) Element names are case sensitive, which means that, for example, itemnumber, itemNumber, and ItemNumber are unique elements.
2) Element names must begin with a letter or the underscore character ( _ ) and may not contain blank spaces. Thus, you cannot name an element Item Number, but you can name it Item_Number.
3) Element names cannot begin with the string xml because that group of characters is reserved for special XML commands.
4) The name in an element's closing tag must exactly match the name in the opening tag.
5) Element names can be used more than once, so the element names can mean different things at different points in the hierarchy of an XML document.
Answers may vary. Students can select any three.
