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\>/",$title );
preg_match_all( "/\(.*?)\<\/publisher\>/",$publisher );
echo( $title[1][0]." - ".$author[1][0]." - ".$publisher[1][0]."\n" );
}
?>
4.解析XML到数组
";
$parser = xml_parser_create(); //创建解析器
xml_parse_into_struct($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);
?>
-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];
?>
