在php中对xml文档操作我们有很多类可以使用,php SimpleXML就是一个很不错的xml解析器,下面我来给大家举两个应用实例.
例,生成xml文档,代码如下:
- class SimpleXMLExtended extends SimpleXMLElement {
- public function addCData($cdata_text) {
- $node = dom_import_simplexml($this);
- $no = $node->ownerDocument;
- $node->appendChild($no->createCDATASection($cdata_text));
- }
- }
- function array2xml($array, $xml = false){
- if($xml === false){
- $xml = new SimpleXMLExtended('<root/>');
- }
- foreach($array as $key => $value){
- if(is_array($value)){
- array2xml($value, $xml->addChild($key));
- }else{
- //如果包含汉字,转编码
- if (preg_match("/([x81-xfe][x40-xfe])/", $value, $match)) {
- $value = iconv('gbk', 'utf-8', $value);
- }
- $xml->$key = NULL; // VERY IMPORTANT! We need a node where to append
- $xml->$key->addCData($value);
- //$xml->$key->addAttribute('lang', 'en');
- // $xml->addChild($key, $value);
- }
- } //开源代码phpfensi.com
- return $xml->asXML();
- }
例,SimpleXMLElement解析xml,代码如下:
- <?php
- $content = <<<XML
- <?xml version="1.0" encoding="UTF-8"?>
- <test>
- <global_setting>
- <ping_protocol>HTTP</ping_protocol>
- <ping_port>80</ping_port>
- <ping_path>/index.html</ping_path>
- <response_timeout>5000</response_timeout>
- <health_check_interval>3000</health_check_interval>
- <unhealthy_threshold>2</unhealthy_threshold>
- <healthy_threshold>3</healthy_threshold>
- </global_setting>
- <instances>
- <instance ip="192.168.234.121"/>
- <instance ip="192.168.234.28"/>
- </instances>
- </test>
- XML;
- $test = new SimpleXMLElement($content);
- //获得ping_protocol的值
- $ping_protocol = $test->global_setting->ping_protocol;
- echo "ping_protocol : $ping_protocol n";
- //开源代码phpfensi.com
- //打印出所有instance的IP
- foreach ( $test->instances->instance as $instance) {
- echo "IP: {$instance['ip']} n" ;
- }
