XML Tags Vs. HTML Tags
XML tags define the data, whereas HTML tags define the page layout, but the tag structure is the same. Text elements are wrapped in "open" and "close" tags, also called "start" and "end" tags, which begin with the less-than (<) character and end with greater-than (>). The HTML in this example defines font size and makes the date boldface. Note that all close (end) tags contain a slash (/) after the beginning less-than (<) character.
