PHP读取XML文件的方法

本文实例总结了PHP读取XML格式文件的方法。分享给大家供大家参考，具体如下：

books.xml文件：

1.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];
?>
