How to create HTML DOM object?

How to find HTML elements?
// Find all anchors, returns a array of element objects
$ret = $html->find(‘a‘);
// Find (N)th anchor, returns element object or null if not found (zero based)
$ret = $html->find(‘a‘, 0);
// Find lastest anchor, returns element object or null if not found (zero based)
$ret = $html->find(‘a‘, -1);
// Find all <div> with the id attribute
$ret = $html->find(‘div[id]‘);
// Find all <div> which attribute id=foo
$ret = $html->find(‘div[id=foo]‘);
// Find all element which id=foo
$ret = $html->find(‘#foo‘);
// Find all element which class=foo
$ret = $html->find(‘.foo‘);
// Find all element has attribute id
$ret = $html->find(‘*[id]‘);
// Find all anchors and images
$ret = $html->find(‘a, img‘);
// Find all anchors and images with the "title" attribute
$ret = $html->find(‘a[title], img[title]‘);
// Find all <li> in <ul>
$es = $html->find(‘ul li‘);
// Find Nested <div> tags
$es = $html->find(‘div div div‘);
// Find all <td> in <table> which class="hello"
$es = $html->find(‘table.hello td‘);
// Find all td tags with attribite align=center in table tags
$es = $html->find(‘‘table td[align=center]‘);
// Find all <li> in <ul>
foreach($html->find(‘ul‘) as $ul)
{
foreach($ul->find(‘li‘) as $li)
{
// do something...
}
}
// Find first <li> in first <ul>
$e = $html->find(‘ul‘, 0)->find(‘li‘, 0);
