+ -
+
- Basics +
- Advanced +
- Descendant selectors +
- Nested selectors +
- Attribute Filters +
- Text & Comments +
+
+ // 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]');
+
+ + $ret = $html->find('a');
+
+ // Find (N)th anchor, returns element object or null if not found (zero based)
+ $ret = $html->find('a', 0);

+
+
+
+ Supports these operators in attribute selectors:
+
+
+
+ +
| Filter | +Description | +
|---|---|
| [attribute] | +Matches elements that have the specified attribute. | +
| [!attribute] | +Matches elements that don't have the specified attribute. | +
| [attribute=value] | +Matches elements that have the specified attribute with a certain value. | +
| [attribute!=value] | +Matches elements that don't have the specified attribute with a certain value. | +
| [attribute^=value] | +Matches elements that have the specified attribute and it starts with a certain value. | +
| [attribute$=value] | +Matches elements that have the specified attribute and it ends with a certain value. | +
| [attribute*=value] | +Matches elements that have the specified attribute and it contains a certain value. | +
+
+ // 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

+ // 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 text blocks
+ $es = $html->find('text');
+
+ // Find all comment (<!--...-->) blocks

+ {
+ // do something...
+ }
+ }
+
+ // Find first <li> in first <ul>
+ $e = $html->find('ul', 0)->find('li', 0);

How to access the HTML element's attributes?
+ Top +
+
+
+
+
+
+
+ // Get a attribute ( If the attribute is non-value attribute (eg. checked, selected...), it will returns true or false)
+ $value = $e->href;
+
+ // Set a attribute(If the attribute is non-value attribute (eg. checked, selected...), set it's value as true or false)
+ $e->href = 'my link';
+
+ // Remove a attribute, set it's value as null!
+ $e->href = null;
+
+ // Determine whether a attribute exist?
+if(isset($e->href))
+ echo 'href exist!';
+
+ + $value = $e->href;
+
+ // Set a attribute(If the attribute is non-value attribute (eg. checked, selected...), set it's value as true or false)
+ $e->href = 'my link';
+
+ // Remove a attribute, set it's value as null!
+ $e->href = null;
+
+ // Determine whether a attribute exist?
+if(isset($e->href))
+ echo 'href exist!';
+
+
+ // Example
+ $html = str_get_html("<div>foo <b>bar</b></div>");
+ $e = $html->find("div", 0);
+
+ echo $e->tag; // Returns: " div"
+ echo $e->outertext; // Returns: " <div>foo <b>bar</b></div>"
+ echo $e->innertext; // Returns: " foo <b>bar</b>"
+ echo $e->plaintext; // Returns: " foo bar"
+
+ +
+
+
+ + $html = str_get_html("<div>foo <b>bar</b></div>");
+ $e = $html->find("div", 0);
+
+ echo $e->tag; // Returns: " div"
+ echo $e->outertext; // Returns: " <div>foo <b>bar</b></div>"
+ echo $e->innertext; // Returns: " foo <b>bar</b>"
+ echo $e->plaintext; // Returns: " foo bar"
+
+ +
| Attribute Name | +Usage | +
|---|---|
| $e->tag | +Read or write the tag name of element. | +
| $e->outertext | +Read or write the outer HTML text of element. | +
| $e->innertext | +Read or write the inner HTML text of element. | +
| $e->plaintext | +Read or write the plain text of element. | +
+
+ // Extract contents from HTML
+echo $html->plaintext;
+
+ + // Wrap a element
+ $e->outertext = '<div class="wrap">' . $e->outertext . '<div>';
+
+ // Remove a element, set it's outertext as an empty string
+ $e->outertext = '';
+
+ // Append a element
+$e->outertext = $e->outertext . '<div>foo<div>';
+
+// Insert a element
+$e->outertext = '<div>foo<div>' . $e->outertext;
+
+ +echo $html->plaintext;
+
+ + // Wrap a element
+ $e->outertext = '<div class="wrap">' . $e->outertext . '<div>';
+
+ // Remove a element, set it's outertext as an empty string
+ $e->outertext = '';
+
+ // Append a element
+$e->outertext = $e->outertext . '<div>foo<div>';
+
+// Insert a element
+$e->outertext = '<div>foo<div>' . $e->outertext;

How to traverse the DOM tree?
+ Top +
+
+
+
+
+
+ // If you are not so familiar with HTML DOM, check this link to learn more...
+
+ // Example
+ echo $html->find("#div1", 0)->children(1)->children(1)->children(2)->id;
+ // or
+ echo $html->getElementById("div1")->childNodes(1)->childNodes(1)->childNodes(2)->getAttribute('id');
+ +
+ // Example
+ echo $html->find("#div1", 0)->children(1)->children(1)->children(2)->id;
+ // or
+ echo $html->getElementById("div1")->childNodes(1)->childNodes(1)->childNodes(2)->getAttribute('id');
+
+
+ You can also call methods with Camel naming convertions.
+
+
+
+ +
| Method | +Description | +
|---|---|
|
+ mixed $e->children ( [int $index] ) |
+ Returns the Nth child object if index is set, otherwise return an array of children. | +
|
+ element $e->parent () |
+ Returns the parent of element. | +
|
+ element $e->first_child () |
+ Returns the first child of element, or null if not found. | +
|
+ element $e->last_child () |
+ Returns the last child of element, or null if not found. | +
|
+ element $e->next_sibling () |
+ Returns the next sibling of element, or null if not found. | +
|
+ element $e->prev_sibling () |
+ Returns the previous sibling of element, or null if not found. | +
How to dump contents of DOM object?
+ Top +
+
+
+ -
+
- Quick way +
- Object-oriented way +
+
+ // Dumps the internal DOM tree back into string
+ $str = $html->save();
+
+ // Dumps the internal DOM tree back into a file
+ $html->save('result.htm');
+ + $str = $html->save();
+
+ // Dumps the internal DOM tree back into a file
+ $html->save('result.htm');
+
+ // Dumps the internal DOM tree back into string
+ $str = $html;
+
+ // Print it!
+ echo $html;
+
+ + $str = $html;
+
+ // Print it!
+ echo $html;
+
How to customize the parsing behavior?
+ Top +
+
+
+
+
+
+ // Write a function with parameter "$element"
+ function my_callback($element) {
+ // Hide all <b> tags
+ if ($element->tag=='b')
+ $element->outertext = '';
+ }
+
+ // Register the callback function with it's function name
+ $html->set_callback('my_callback');
+
+ // Callback function will be invoked while dumping
+ echo $html; +
+ + function my_callback($element) {
+ // Hide all <b> tags
+ if ($element->tag=='b')
+ $element->outertext = '';
+ }
+
+ // Register the callback function with it's function name
+ $html->set_callback('my_callback');
+
+ // Callback function will be invoked while dumping
+ echo $html; +
