| 21 | // ======== ATTENTION, PLEASE READ ======== |
||
| 22 | // This supplement script was created to support rare PHP installations that |
||
| 23 | // do not contain SimpleXML, for example at PHP you need to explicitly |
||
| 24 | // install the package "php-xml" if you want to have SimpleXML (In the PHP |
||
| 25 | // documentation, it is written that SimpleXML is available to all, which is |
||
| 26 | // not true). |
||
| 27 | // |
||
| 28 | // Beware that the supplement behaves differently than the real SimpleXML! |
||
| 29 | // (If you know how to improve this, please feel free to send me a patch) |
||
| 30 | // |
||
| 31 | // Just a few differences towards the original SimpleXML |
||
| 32 | // - print_r() looks different |
||
| 33 | // - The supplement requires that an XML string begins with "<!DOCTYPE" or "<?xml", |
||
| 34 | // otherwise, the first element will not be stripped away |
||
| 35 | // - The supplement is slow because of regular expressions |
||
| 36 | // - Many functions like "asXML" are not implemented |
||
| 510 | daniel-mar | 37 | // - There might be other incompatibilities |
| 480 | daniel-mar | 38 | // |
| 39 | // So, if you want to use the SimpleXML supplement, then please carefully |
||
| 40 | // test it with your application if it works. |
||
| 41 | // ======================================== |
