| 286 |  * #### Currently implemented selectors:
 | 
      ||
| 287 |  *
 | 
      ||
| 288 |  * - /User/id (similar to the classic {n}.User.id)
 | 
      ||
| 289 |  * - /User[2]/name (selects the name of the second User)
 | 
      ||
| 290 |  * - /User[id>2] (selects all Users with an id > 2)
 | 
      ||
| 291 |  * - /User[id>2][<5] (selects all Users with an id > 2 but < 5)
 | 
      ||
| 292 |  * - /Post/Comment[author_name=john]/../name (Selects the name of all Posts that have at least one Comment written by john)
 | 
      ||
| 293 |  * - /Posts[name] (Selects all Posts that have a 'name' key)
 | 
      ||
| 294 |  * - /Comment/.[1] (Selects the contents of the first comment)
 | 
      ||
| 295 |  * - /Comment/.[:last] (Selects the last comment)
 | 
      ||
| 296 |  * - /Comment/.[:first] (Selects the first comment)
 | 
      ||
| 297 |  * - /Comment[text=/cakephp/i] (Selects the all comments that have a text matching the regex /cakephp/i)
 | 
      ||
| 298 |  * - /Comment/@* (Selects the all key names of all comments)
 | 
      ||
| 299 |  *
 | 
      ||
| 300 |  * #### Other limitations:
 | 
      ||
| 301 |  *
 | 
      ||
| 302 |  * - Only absolute paths starting with a single '/' are supported right now
 | 
      ||
| 303 |  *
 | 
      ||
| 304 |  * **Warning**: Even so it has plenty of unit tests the XPath support has not gone through a lot of
 | 
      ||
| 305 |  * real-world testing. Please report Bugs as you find them. Suggestions for additional features to
 | 
      ||
| 306 |  * implement are also very welcome!
 | 
      ||

 | 
      ||
| 308 |  * @param string $path An absolute XPath 2.0 path

 | 
      ||
