387 | =head1 DESCRIPTION |
388 | |
389 | Given a L<HTML::Zoom> stream, provide methods to apply filters which |
390 | alter the content of that stream. |
391 | |
f6644c71 |
392 | =head1 METHODS |
393 | |
394 | This class defines the following public API |
395 | |
e225a4bd |
396 | =head2 set_attribute |
f6644c71 |
397 | |
f8ad684d |
398 | Sets an attribute of a given name to a given value for all matching selections. |
399 | |
400 | $html_zoom |
401 | ->select('p') |
402 | ->set_attribute(class=>'paragraph') |
403 | ->select('div') |
434a11c8 |
404 | ->set_attribute(name=>'class', value=>'divider'); |
405 | |
f8ad684d |
406 | |
407 | Overrides existing values, if such exist. When multiple L</set_attribute> |
408 | calls are made against the same or overlapping selection sets, the final |
409 | call wins. |
f6644c71 |
410 | |
e225a4bd |
411 | =head2 add_to_attribute |
f6644c71 |
412 | |
434a11c8 |
413 | Adds a value to an existing attribute, or creates one if the attribute does not |
414 | yet exist. |
f6644c71 |
415 | |
434a11c8 |
416 | $html_zoom |
417 | ->select('p') |
418 | ->set_attribute(class=>'paragraph') |
419 | ->then |
420 | ->add_to_attribute(name=>'class', value=>'divider'); |
f6644c71 |
421 | |
434a11c8 |
422 | Attributes with more than one value will have a dividing space. |
423 | |
e225a4bd |
424 | =head2 remove_attribute |
434a11c8 |
425 | |
426 | Removes an attribute and all its values. |
427 | |
428 | $html_zoom |
429 | ->select('p') |
430 | ->set_attribute(class=>'paragraph') |
431 | ->then |
432 | ->remove_attribute('class'); |
433 | |
434 | Removes attributes from the original stream or events already added. |
f6644c71 |
435 | |
436 | =head2 collect |
437 | |
ac3acd87 |
438 | Collects and extracts results of L<HTML::Zoom/select>. It takes the following |
439 | optional common options as hash reference. |
440 | |
441 | =over |
442 | |
443 | =item into [ARRAY REFERENCE] |
444 | |
445 | Where to save collected events (selected elements). |
446 | |
447 | $z1->select('#main-content') |
448 | ->collect({ into => \@body }) |
449 | ->run; |
450 | $z2->select('#main-content') |
451 | ->replace(\@body) |
452 | ->memoize; |
453 | |
454 | =item filter [CODE] |
455 | |
456 | Run filter on collected elements (locally setting $_ to stream, and passing |
457 | stream as an argument to given code reference). Filtered stream would be |
458 | returned. |
459 | |
460 | $z->select('.outer') |
461 | ->collect({ |
462 | filter => sub { $_->select('.inner')->replace_content('bar!') }, |
463 | passthrough => 1, |
464 | }) |
465 | |
466 | It can be used to further filter selection. For example |
467 | |
468 | $z->select('tr') |
469 | ->collect({ |
470 | filter => sub { $_->select('td') }, |
471 | passthrough => 1, |
472 | }) |
473 | |
474 | is equivalent to (not implemented yet) descendant selector combination, i.e. |
475 | |
476 | $z->select('tr td') |
477 | |
478 | =item passthrough [BOOLEAN] |
479 | |
480 | Extract copy of elements; the stream is unchanged (it does not remove collected |
481 | elements). For example without 'passthrough' |
482 | |
483 | HTML::Zoom->from_html('<foo><bar /></foo>') |
484 | ->select('foo') |
485 | ->collect({ content => 1 }) |
486 | ->to_html |
487 | |
488 | returns '<foo></foo>', while with C<passthrough> option |
489 | |
490 | HTML::Zoom->from_html('<foo><bar /></foo>') |
491 | ->select('foo') |
492 | ->collect({ content => 1, passthough => 1 }) |
493 | ->to_html |
494 | |
495 | returns '<foo><bar /></foo>'. |
496 | |
497 | =item content [BOOLEAN] |
498 | |
499 | Collect content of the element, and not the element itself. |
500 | |
501 | For example |
502 | |
503 | HTML::Zoom->from_html('<h1>Title</h1><p>foo</p>') |
504 | ->select('h1') |
505 | ->collect |
506 | ->to_html |
507 | |
508 | would return '<p>foo</p>', while |
509 | |
510 | HTML::Zoom->from_html('<h1>Title</h1><p>foo</p>') |
511 | ->select('h1') |
512 | ->collect({ content => 1 }) |
513 | ->to_html |
514 | |
515 | would return '<h1></h1><p>foo</p>'. |
516 | |
517 | See also L</collect_content>. |
518 | |
519 | =item flush_before [BOOLEAN] |
520 | |
521 | Generate C<flush> event before collecting, to ensure that the HTML generated up |
522 | to selected element being collected is flushed throught to the browser. Usually |
523 | used in L</repeat> or L</repeat_content>. |

526 | |
527 | =head2 collect_content |
528 | |
ac3acd87 |
529 | Collects contents of L<HTML::Zoom/select> result. |
530 | |
531 | HTML::Zoom->from_file($foo) |
532 | ->select('#main-content') |
533 | ->collect_content({ into => \@foo_body }) |
534 | ->run; |
535 | $z->select('#foo') |
536 | ->replace_content(\@foo_body) |
537 | ->memoize; |
538 | |
539 | Equivalent to running L</collect> with C<content> option set. |
f6644c71 |
540 | |
541 | =head2 add_before |
542 | |
ac3acd87 |
543 | Given a L<HTML::Zoom/select> result, add given content (which might be string, |
544 | array or another L<HTML::Zoom> object) before it. |
545 | |
546 | $html_zoom |
547 | ->select('input[name="foo"]') |
548 | ->add_before(\ '<span class="warning">required field</span>'); |
f6644c71 |
549 | |
550 | =head2 add_after |
551 | |
ac3acd87 |
552 | Like L</add_before>, only after L<HTML::Zoom/select> result. |
553 | |
554 | $html_zoom |
555 | ->select('p') |
556 | ->add_after("\n\n"); |
557 | |
558 | You can add zoom events directly |
559 | |
560 | $html_zoom |
561 | ->select('p') |
562 | ->add_after([ { type => 'TEXT', raw => 'O HAI' } ]); |
f6644c71 |

566 | TBD |
567 | |
568 | =head2 append_content |
569 | |
570 | TBD |
571 | |
572 | =head2 replace |
573 | |
ac3acd87 |
574 | Given a L<HTML::Zoom/select> result, replace it with a string, array or another |
575 | L<HTML::Zoom> object. It takes the same optional common options as L</collect> |
576 | (via hash reference). |
f6644c71 |
577 | |
578 | =head2 replace_content |
579 | |
244252e7 |
580 | Given a L<HTML::Zoom/select> result, replace the content with a string, array |
581 | or another L<HTML::Zoom> object. |
f6644c71 |
582 | |
ac3acd87 |
583 | $html_zoom |
584 | ->select('title, #greeting') |
585 | ->replace_content('Hello world!'); |
586 | |
f6644c71 |
587 | =head2 repeat |
588 | |
ac3acd87 |
589 | $zoom->select('.item')->repeat(sub { |
590 | if (my $row = $db_thing->next) { |
591 | return sub { $_->select('.item-name')->replace_content($row->name) } |
592 | } else { |
593 | return |
594 | } |
595 | }, { flush_before => 1 }); |
596 | |
597 | Run I<$repeat_for>, which should be iterator (code reference) returning |
598 | subroutines, reference to array of subroutines, or other zoom-able object |
599 | consisting of transformations. Those subroutines would be run with $_ |
600 | local-ized to result of L<HTML::Zoom/select> (of collected elements), and with |
601 | said result passed as parameter to subroutine. |
602 | |
603 | You might want to use iterator when you don't have all elements upfront |
604 | |
605 | $zoom = $zoom->select('.contents')->repeat(sub { |
606 | while (my $line = $fh->getline) { |
607 | return sub { |
608 | $_->select('.lno')->replace_content($fh->input_line_number) |
609 | ->select('.line')->replace_content($line) |
610 | } |
611 | } |
612 | return |
613 | }); |
614 | |
615 | You might want to use array reference if it doesn't matter that all iterations |
616 | are pre-generated |
617 | |
618 | $zoom->select('table')->repeat([ |
619 | map { |
620 | my $elem = $_; |
621 | sub { |
622 | $_->select('td')->replace_content($e); |
623 | } |
624 | } @list |
625 | ]); |
626 | |
627 | In addition to common options as in L</collect>, it also supports |
628 | |
629 | =over |
630 | |
631 | =item repeat_between [SELECTOR] |
632 | |
633 | Selects object to be repeated between items. In the case of array this object |
634 | is put between elements, in case of iterator it is put between results of |
635 | subsequent iterations, in the case of streamable it is put between events |
636 | (->to_stream->next). |
637 | |
638 | See documentation for L</repeat_content> |
639 | |
640 | =back |
f6644c71 |
641 | |
642 | =head2 repeat_content |
643 | |
ac3acd87 |
644 | Given a L<HTML::Zoom/select> result, run provided iterator passing content of |
645 | this result to this iterator. Accepts the same options as L</repeat>. |
646 | |
647 | Equivalent to using C<contents> option with L</repeat>. |
648 | |
649 | $html_zoom |
650 | ->select('#list') |
651 | ->repeat_content( |
652 | [ |
653 | sub { |
654 | $_->select('.name')->replace_content('Matt') |
655 | ->select('.age')->replace_content('26') |
656 | }, |
657 | sub { |
658 | $_->select('.name')->replace_content('Mark') |
659 | ->select('.age')->replace_content('0x29') |
660 | }, |
661 | sub { |
662 | $_->select('.name')->replace_content('Epitaph') |
663 | ->select('.age')->replace_content('<redacted>') |
664 | }, |
665 | ], |
666 | { repeat_between => '.between' } |
667 | ); |
