+<blockquote><pre>
+&lt;condition propery="legal-password"&gt;
+  &lt;matches pattern="[1-9]" string="${user-input}"/&gt;
+&lt;/condition&gt;
+&lt;fail message="Your password should at least contain one number"
+      unless="legal-password"/&gt;
+</pre></blockquote>
+  <p>
+    The following example sets the property "ok" if
+    the property "input" is three characters long, starting
+    with 'a' and ending with 'b'.
+  </p>
+<blockquote><pre>
+&lt;condition property="ok"&gt;
+  &lt;matches string="${input}" pattern="^a.b$"/&gt;
+&lt;/condition&gt;
+</pre></blockquote>
+  <p>
+    The following defines a reference regular expression for
+    matching dates and then uses antunit to check if the
+    property "today" is in the correct format:
+  </p>
+<blockquote><pre>
+&lt;regexp id="date.pattern" pattern="^[0123]\d-[01]\d-[12]\d\d\d$"/&gt;
 
+&lt;au:assertTrue xmlns:au="antlib:org.apache.ant.antunit"&gt;
+  &lt;matches string="${today}"&gt;
+    &lt;regexp refid="date.pattern"/&gt;
+  &lt;/matches&gt;
+&lt;/au:assertTrue&gt;
+</pre></blockquote>
+  <p>
+    The following example shows the use of the singleline and the casesensitive
+    flags.
+  </p>
+<blockquote><pre>
+&lt;au:assertTrue&gt;
+  &lt;matches string="AB${line.separator}C" pattern="^ab.*C$"
+           casesensitive="false"
+           singleline="true"/&gt;
+&lt;/au:assertTrue&gt;
+&lt;au:assertFalse&gt;
+  &lt;matches string="AB${line.separator}C" pattern="^ab.*C$"
