    "description": "The RegExpValidator class lets you use a regular expression to validate a field. You pass a regular expression to the validator using the <code>expression</code> property, and additional flags to control the regular expression pattern matching using the <code>flags</code> property.  <p>The validation is successful if the validator can find a match of the regular expression in the field to validate. A validation error occurs when the validator finds no match.</p>  <p>The RegExpValidator class dispatches the <code>valid</code> and <code>invalid</code> events. For an <code>invalid</code> event, the event object is an instance of the ValidationResultEvent class, and it contains an Array of ValidationResult objects.</p>  <p>However, for a <code>valid</code> event, the ValidationResultEvent object contains an Array of RegExpValidationResult objects. The RegExpValidationResult class is a child class of the ValidationResult class, and contains additional properties used with regular expressions, including the following:</p> <ul> <li><code>matchedIndex</code> An integer that contains the starting index in the input String of the match.</li> <li><code>matchedString</code> A String that contains the substring of the input String that matches the regular expression.</li> <li><code>matchedSubStrings</code> An Array of Strings that contains parenthesized substring matches, if any. If no substring matches are found, this Array is of length 0.  Use matchedSubStrings[0] to access the first substring match.</li> </ul>   <p>The <code>&lt;mx:RegExpValidator&gt;</code> tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:</p>  <pre>\\n &lt;mx:RegExpValidator\\n expression=&quot;<i>No default</i>&quot;\\n flags=&quot;<i>No default</i>&quot;\\n noExpressionError=&quot;The expression is missing.&quot;\\n noMatchError=&quot;The field is invalid.&quot;\\n /&gt;\\n </pre>",
