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
