* is delegated to Set::classicExtract(). Also the $path and $data arguments are
|
| 284 |
* reversible.
|
| 285 |
*
|
| 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!
|
| 307 |
*
|
| 308 |
* @param string $path An absolute XPath 2.0 path
|
| 309 |
* @param array $data An array of data to extract from
|
| 310 |
* @param array $options Currently only supports 'flatten' which can be disabled for higher XPath-ness
|
| 311 |
* @return mixed An array of matched items or the content of a single selected item or null in any of these cases: $path or $data are null, no items found.
