php 使用expat方式解析xml文件操作示例

本文实例讲述了php 使用expat方式解析xml文件操作。分享给大家供大家参考,具体如下: test.xml: <?xml version="1.0" encoding="UTF-8"?> <notes> <note> <to>George</to> <from>John</from> <heading>Reminder</heading> <body>Don't forget the meeting!</body> </note> <note> <to>George2</to> <from>John2</from> <heading>Reminder2</heading> <body>Don't forget the meeting!2</body> </note> <instances> <instance st="192.168.234.121" /> <instance st="192.168.234.28" /> </instances> </notes> PHP文件: <?php // Initialize the XML parser $parser = xml_parser_create(); // Function to use at the start of an element function start($parser, $element_name, $element_attrs) { switch ($element_name) { case "NOTE": echo "-- Note --<br />"; break; case "TO": echo "To: "; break; case "FROM": echo "From: "; break; case "HEADING": echo "Heading: "; break; case "BODY": echo "Message: "; } } // Function to use at the end of an element function stop($parser, $element_name) { echo "<br />"; } // Function to use when finding character data function char($parser, $data) { echo $data; } // Specify element handler xml_set_element_handler($parser, "start", "stop"); // Specify data handler xml_set_character_data_handler($parser, "char"); // Open XML file // $fp = fopen("test.xml", "r"); // Read data // while ($data = fread($fp, 10)) { // xml_parse($parser, $data, feof($fp)) or die(sprintf("XML Error: %s at line %d", xml_error_string(xml_get_error_code($parser)), xml_get_current_line_number($parser))); // } // fclose($fp); $data = file_get_contents("test.xml"); xml_parse($parser, $data) or die(sprintf("XML Error: %s at line %d", xml_error_string(xml_get_error_code($parser)), xml_get_current_line_number($parser))); // Free the XML parser xml_parser_free($parser); ?> 运行结果: -- Note -- To: George From: John Heading: Reminder Message: Don't forget the meeting! -- Note -- To: George2 From: John2 Heading: Reminder2 Message: Don't forget the meeting!2 PS:这里再为大家提供几款关于xml操作的在线工具供大家参考使用: 在线XML/JSON互相转换工具: http://tools.jb51.net/code/xmljson 在线格式化XML/在线压缩XML: http://tools.jb51.net/code/xmlformat XML在线压缩/格式化工具: http://tools.jb51.net/code/xml_format_compress XML代码在线格式化美化工具: http://tools.jb51.net/code/xmlcodeformat 更多关于PHP相关内容感兴趣的读者可查看本站专题:《PHP针对XML文件操作技巧总结》、《PHP数组(Array)操作技巧大全》、《php字符串(string)用法总结》、《php面向对象程序设计入门教程》、《php+mysql数据库操作入门教程》及《php常见数据库操作技巧汇总》 希望本文所述对大家PHP程序设计有所帮助。...
