DOMDocument方法

load( 'books.xml' ); $books = $doc->getElementsByTagName( "book" ); foreach( $books as $book ){ $authors = $book->getElementsByTagName( "author" ); $author = $authors->item(0)->nodeValue; $publishers = $book->getElementsByTagName( "publisher" ); $publisher = $publishers->item(0)->nodeValue; $titles = $book->getElementsByTagName( "title" ); $title = $titles->item(0)->nodeValue; echo "$title - $author - $publisher\n"; echo "
"; } ?>

2.用 SAX 解析器读取 XML：

3.用正则表达式解析 XML：

(.*?)\<\/book\>/s", $xml, $bookblocks ); foreach( $bookblocks[1] as $block ){ preg_match_all( "/\(.*?)\<\/author\>/", $block, $author ); preg_match_all( "/\(.*?)\<\/title\>/", $block, $title ); preg_match_all( "/\(.*?)\<\/publisher\>/", $block, $publisher ); echo( $title[1][0]." - ".$author[1][0]." - ".$publisher[1][0]."\n" ); } ?>

4.解析XML到数组

简单的XML数据"; $parser = xml_parser_create(); //创建解析器 xml_parse_into_struct($parser, $data, $values, $index); //解析到数组 xml_parser_free($parser); //释放资源 //显示数组结构 echo "\n索引数组\n"; print_r($index); echo "\n数据数组\n"; print_r($values); ?>

5.检查XML是否有效

"; //输出错误行，列及其错误信息 $error_line = xml_get_current_line_number($xml_parser); $error_row = xml_get_current_column_number($xml_parser); $error_string = xml_error_string(xml_get_error_code($xml_parser)); $message = sprintf("［第%d行，%d列］：%s", $error_line, $error_row, $error_string); echo $message; } else { echo "该XML文档是结构良好的。"; } //关闭XML解析器指针，释放资源 xml_parser_free($xml_parser); ?>

6.可用于精确的读取XML

test.xml

test.php:

 -1) { try { //加载解析xml $xml = simplexml_load_string($file); if($xml) { //echo $this->result; //获取节点值 $CONNECT_ID = $xml->CONNECT_ID; $MO_MESSAGE_ID = $xml->MO_MESSAGE_ID; $RECEIVE_DATE = $xml->RECEIVE_DATE; $RECEIVE_TIME = $xml->RECEIVE_TIME; $GATEWAY_ID = $xml->GATEWAY_ID; $VALID = $xml->VALID; $CITY_CODE = $xml->CITY_CODE; $CITY_NAME = $xml->CITY_NAME; $STATE_CODE = $xml->CITY_CODE; $STATE_NAME = $xml->STATE_NAME; $TP_PID = $xml->TP_PID; $TP_UDHI = $xml->TP_UDHI; $MSISDN = $xml->MSISDN; $MESSAGE_TYPE = $xml->MESSAGE_TYPE; $MESSAGE = $xml->MESSAGE;//短信 $LONG_CODE = $xml->LONG_CODE; $SERVICE_CODE = $xml->SERVICE_CODE; preg_match("/(561)\d{1,2}/", $MESSAGE, $code); switch($code[0]) { case 5618 : $myData[message] = $MESSAGE; break; default : $myData[] = '没有短消息。'; break; } } else { echo "加载xml文件错误。"; } } catch(exception $e){ print_r($e); } } else { echo "没有该XML文件。"; } echo ""; print_r($myData); echo "
"; echo $myData[message
