The examples in this article summarize the method of PHP readingXMLformat files. Share it with everyone for your reference, the details are as follows:

books.xml file:

1. DOMDocument method

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. Use SAX parser to read XML:

3. Useregular expressionto parse 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. Parse XML intoarray

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. Check whether the XML is valid

"; //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. Can be used to read XML accurately

"; print_r($myData); echo "
"; echo $myData[message
