deb4998ba50060c48cce222fd18a8eed053918d7vboxsync to "none", no encoding will be done. If set to "url",

deb4998ba50060c48cce222fd18a8eed053918d7vboxsync appropriate for use within URLs in links, etc.) will be

deb4998ba50060c48cce222fd18a8eed053918d7vboxsync ISO-8859-1 character encoding will be encoded. This

deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <p>The <strong><code>if</code></strong> element works like an
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync if statement in a programming language. The test condition is
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync evaluated and if the result is true, then the text until the

deb4998ba50060c48cce222fd18a8eed053918d7vboxsync output stream.</p>
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <strong><code>else</code></strong> statements are be used the
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync put text into the output stream if the original test_condition
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync was false. These elements are optional.</p>
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <p>The <strong><code>endif</code></strong> element ends the
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <strong><code>if</code></strong> element and is required.</p>
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <p><em>test_condition</em> is one of the following:</p>
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <dd>Compare string1 with string 2. If string2 has the form
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync expression. Regular expressions have the same syntax as those
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <dt><em>test_condition1</em> || <em>test_condition2</em></dt>
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <p>"<em>=</em>" and "<em>!=</em>" bind more tightly than
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync "<em>&&</em>" and "<em>||</em>". "<em>!</em>" binds
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync most tightly. Thus, the following are equivalent:</p>
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <!--#if expr="$a = test1 && $b = test2" -->
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <!--#if expr="($a = test1) && ($b = test2)" -->
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <p>Anything that's not recognized as a variable or an operator
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync is treated as a string. Strings can also be quoted:
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <em>'string'</em>. Unquoted strings can't contain whitespace
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync (blanks and tabs) because it is used to separate tokens such as
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync variables. If multiple strings are found in a row, they are
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync concatenated using blanks. So,</p>
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <em>string1 string2</em> results in <em>string1 string2</em>
deb4998ba50060c48cce222fd18a8eed053918d7vboxsync <em>'string1 string2'</em> results in <em>string1 string2</em>
