一个用PHP5.X编写的HTML Dom解析器。Dom Parser非常适合处理XML和HTML。Dom解析器基于树进行访问，在访问数据之前，将数据加载到dom对象中，并将数据更新到Web浏览器。以下示例显示如何在Web浏览器中访问HTML数据。
<?php
$html = "
<head>
<title>Tutorialspoint</title>
</head>
<body>
<h2>Course details</h2>
<table border = "0">
<tbody>
<tr>
<td>Android</td>
<td>Gopal</td>
<td>Sairam</td>
</tr>
<tr>
<td>Hadoop</td>
<td>Gopal</td>
<td>Satish</td>
</tr>
<tr>
<td>HTML</td>
<td>Gopal</td>
<td>Raju</td>
</tr>
<tr>
<td>Web technologies</td>
<td>Gopal</td>
<td>Javed</td>
</tr>
<tr>
<td>Graphic</td>
<td>Gopal</td>
<td>Satish</td>
</tr>
<tr>
<td>Writer</td>
<td>Kiran</td>
<td>Amith</td>
</tr>
<tr>
<td>Writer</td>
<td>Kiran</td>
<td>Vineeth</td>
</tr>
</tbody>
</table>
</body>
</html>
";
/*** a new dom object ***/
$dom = new domDocument;
/*** load the html into the object ***/
$dom->loadHTML($html);
/*** discard white space ***/
$dom->preserveWhiteSpace = false;
/*** the table by its tag name ***/
$tables = $dom->getElementsByTagName("table");
/*** get all rows from the table ***/
$rows = $tables->item(0)->getElementsByTagName("tr");
/*** loop over the table rows ***/
foreach ($rows as $row) {
/*** get each column by tag name ***/
$cols = $row->getElementsByTagName("td");
/*** echo the values ***/
echo "Designation: ".$cols->item(0)->nodeValue."<br />";
echo "Manager: ".$cols->item(1)->nodeValue."<br />";
echo "Team: ".$cols->item(2)->nodeValue;
echo "<hr />";
}
?>
输出结果如下 -
