4 $result = $fmt->formatFile(‘originalFile.xml‘, ‘beautifiedFile.xml‘);
5 if (PEAR::isError($result)) {
6 echo $result->getMessage();
7 exit();
8 }
9 echo "File beautified, awaiting orders!<br />";
10 ?>
2.XML_DTD
引用外部的dtd文件以对xml内容进行验证
1 <?php
2 require_once ‘XML/DTD/XmlValidator.php‘;
3 $dtd_file = realpath(‘myfile.dtd‘);
4 $xml_file = realpath(‘myfile.xml‘);
5 $validator = new XML_DTD_XmlValidator();
6 if (!$validator->isValid($dtd_file, $xml_file)) {
7 die($validator->getMessage());
8 }
9 ?>

4 /* Where Relax NG is available, we can force validation of the feed */
5 $validate = true;
6 /* Whether or not to suppress non-fatal warnings */
7 $suppress_warnings = false;
8 /* If the feed is not valid XML and the tidy extension is installed we can * attempt to use it to fix the feed */
9 $use_tidy = true;

2 require_once ‘XML/Parser.php‘;
3 class myParser extends XML_Parser {
4 function myParser() {
5 parent::XML_Parser();
6 }
7 /** * 处理起始标签 * * @access private * @param resource xml parser 句柄 * @param string 标签名 * @param array 属性值 */
8 function startHandler($xp, $name, $attribs) {
9 printf(‘handle start tag: %s<br />‘, $name);
10 }
11 /** * 处理结束标签 * * @access private * @param resource xml parser 句柄 * @param string 标签名 */
12 function endHandler($xp, $name) {

14 }
15 /** * 处理字符数据 * * @access private * @param resource xml parser 句柄 * @param string 字符数据 */
16 function cdataHandler($xp, $cdata) {
17 // does nothing here, but might e.g. print $cdata
18 }
19 }

1 <?php
2 require_once "XML/RDDL.php";
3
4 // create new RDDL parser
5 $rddl = &new XML_RDDL();
6
7 // parse a document that contains RDDL resources
8 $result = $rddl->parseRDDL(‘http://www.rddl.org‘);
9 // check for error
10 if (PEAR::isError($result)) {
11 echo sprintf( "ERROR: %s (code %d)", $result->getMessage(), $result->getCode());
12 exit;
13 }
14
15 // get all resources
16 $resources = $rddl->getAllResources();
17 echo "<pre>";
18 print_r($resources);
19 echo "</pre>";
20
21 // get one resource by its Id
22 $test = $rddl->getResourceById(‘CSS‘);
23 echo "<pre>";
24 print_r($test);
25 echo "</pre>";
26
27 // get all stylesheets
28 $test = $rddl->getResourcesByNature(‘http://www.w3.org/1999/XSL/Transform‘);
29 echo "<pre>";
30 print_r($test);
31 echo "</pre>";
32
33 // get all normative references
34 $test = $rddl->getResourcesByPurpose(‘http://www.rddl.org/purposes#normative-reference‘);

8 echo "<ul>\n";
9
10 foreach ($rss->getItems() as $item) {
11 echo "<li><a href=\"" . $item[‘link‘] . "\">" . $item[‘title‘] . "</a></li>\n";

5
6 if ($stat->isError($result)) {
7 die("Error: " . $result->getMessage());
8 }
9
10 // total amount of tags:
11 echo "Total tags: " . $stat->countTag() . "<br />";
12
13 // count amount of ‘title‘ attribute, in all tags
14 echo "Occurences of attribute title: " . $stat->countAttribute("title") . "<br />";
