| 401 | =head1 DESCRIPTION | ||||||
| 402 | |||||||
| 403 | L |
||||||
| 404 | broken HTML and XML, so you should not use it for validation. | ||||||
| 405 | |||||||
| 406 | =head1 NODES AND ELEMENTS | ||||||
| 407 | |||||||
| 408 | When we parse an HTML/XML fragment, it gets turned into a tree of nodes. | ||||||
| 409 | |||||||
| 410 | |||||||
| 411 | |||||||
| 412 | |
||||||
| 413 | World! | ||||||
| 414 | |||||||
| 415 | |||||||
| 416 | There are currently eight different kinds of nodes, C |
||||||
| 417 | and C |
||||||
| 418 | |||||||
| 419 | root | ||||||
| 420 | |- doctype (html) | ||||||
| 421 | +- tag (html) | ||||||
| 422 | |- tag (head) | ||||||
| 423 | | +- tag (title) | ||||||
| 424 | | +- raw (Hello) | ||||||
| 425 | +- tag (body) | ||||||
| 426 | +- text (World!) | ||||||
| 427 | |||||||
| 428 | While all node types are represented as L |
||||||
| 429 | apply to elements. | ||||||
| 430 | |||||||
| 431 | =head1 HTML AND XML | ||||||
| 432 | |||||||
| 433 | L |
||||||
| 434 | be lowercase as well. | ||||||
| 435 | |||||||
| 436 | # HTML semantics | ||||||
| 437 | my $dom = Mojo::DOM->new(' Hi! '); |
||||||
| 438 | say $dom->at('p[id]')->text; | ||||||
| 439 | |||||||
| 440 | If an XML declaration is found, the parser will automatically switch into XML mode and everything becomes | ||||||
| 441 | case-sensitive. | ||||||
| 442 | |||||||
| 443 | # XML semantics | ||||||
| 444 | my $dom = Mojo::DOM->new(' Hi! '); |
||||||
| 445 | say $dom->at('P[ID]')->text; | ||||||
| 446 | |||||||
| 447 | HTML or XML semantics can also be forced with the L method. | ||||||
| 448 | |||||||
| 449 | # Force HTML semantics | ||||||
| 450 | my $dom = Mojo::DOM->new->xml(0)->parse(' Hi! '); |
||||||
| 451 | say $dom->at('p[id]')->text; | ||||||
| 452 | |||||||
| 453 | # Force XML semantics | ||||||
| 454 | my $dom = Mojo::DOM->new->xml(1)->parse(' Hi! '); |
||||||
| 455 | say $dom->at('P[ID]')->text; | ||||||
| 456 | |||||||
| 457 | =head1 METHODS | ||||||

| 464 | |||||||
