the class TreeUtil method findWComponents.

/**
 * Retrieves WComponents by their path in the WComponent tree.
 * <p>
 * Paths are specified using class names, starting from the furthest ancestor. To reduce the path lengths, class
 * names do not need to be fully-qualified. The path does not need to explicitly state intermediate components
 * between components, and may include an index suffix to select a particular instance of a component in e.g. a
 * repeater or a set of fields. Some example paths are shown below.
 * </p>
 * Example paths.
 * <dl>
 * <dt><code>{ "MyComponent" }</code></dt>
 * <dd>Matches the first instance of MyComponent.</dd>
 * <dt><code>{ "MyComponent[0]" }</code></dt>

 * <dt><code>{ "MyComponent[1]" }</code></dt>
 * <dd>Matches the second instance of MyComponent.</dd>
