<div class="textblock"><p>C++ API: Regular Expressions. </p>
<h2>Regular Expression API</h2>
<p>The ICU API for processing regular expressions consists of two classes, <code>RegexPattern</code> and <code>RegexMatcher</code>. <code>RegexPattern</code> objects represent a pre-processed, or compiled regular expression. They are created from a regular expression pattern string, and can be used to create <code>RegexMatcher</code> objects for the pattern.</p>
<p>Class <code>RegexMatcher</code> bundles together a regular expression pattern and a target string to which the search pattern will be applied. <code>RegexMatcher</code> includes API for doing plain find or search operations, for search and replace operations, and for obtaining detailed information about bounds of a match. </p>
<p>Note that by constructing <code>RegexMatcher</code> objects directly from regular expression pattern strings application code can be simplified and the explicit need for <code>RegexPattern</code> objects can usually be eliminated. </p>
