Whitespace
Whitespace in a document includes multiple spaces, tab characters, carriage returns,
newline characters, and so on. An XML parser reads and processes XML tags in a
document, but ignores extra whitespace. To an XML parser, there is no difference between
<clip><name>Coffee house wide shot</name><reel>17</reel></clip>
and
<clip>
<name>Coffee house wide shot</name>
<reel>17</reel>
</clip>
Whitespace is permitted so you can make your XML file more readable without
affecting the fundamental structure or meaning.
