用PHP解析XML 的方法

chibs 2008-03-27 11:36:20

关于用PHP解析XML 的方法，有没有不用另外安装什么包，如expat等。。就可以直接解析XML的？

所以，我要的是PHP本身就可以解析XML的语法，请高手指点!!谢谢~~
我学PHP没几天，别怪我问那么菜的问题呵~~

simplexml，PHP自带的。

什么也不用安装，
推荐两种方式
simplexml 比较简单，但是功能也少
dom比较全面，和msxml类似，做过其他语言开发的人很容易上手这个

  $xml ="a.xml";

  $dom = new DOMDocument();

  $dom->load($xml);

  $xml_value = $dom->getElementsByTagName('data');//标签

  foreach($xml_value as $value){

    $nodevalue = $value->nodeValue;

  }

一本书上的例子，可以参考
parse.php

<html>

  <head><title>My Library</title></head>

  <body>

<?php

class BookList{

	var $parser,$record,$current_field='',$field_type,$ends_record,$records;

	function BookList($filename){

		$this->parser=xml_parser_create("utf-8");

		xml_set_object($this->parser,&$this);

		xml_set_element_handler($this->parser,start_element,end_element);

		xml_set_character_data_handler($this->parser,cdata);

		

		//1=单个字段，2=数组字段，3=记录容器

		$this->field_type=array('title'=>1,

		                        'author'=>2,

		                        'isbn'=>1,

		                        'comment'=>1 );

		$this->ends_record=array("book"=>true);

		$x=join("",file($filename));

		xml_parse($this->parser,$x);

		xml_parser_free($this->parser);

	}

	function start_element($p,$element,&$attributes){

		$element=strtolower($element);

		if($this->field_type[$element]!=0){

			$this->current_field=$element;

		}else{

			$this->current_field='';

		}

	}

	function end_element($p,$element){

		$element=strtolower($element);

		if($this->ends_record[$element]){

			$this->records[]=$this->record;

			$this->record=array();

		}

		$this->current_field='';

	}

	function cdata($p,$text){

		if($this->field_type[$this->current_field]===2){

			$this->record[$this->current_field][]=$text;

		}elseif($this->field_type[$this->current_field]===1){

			$this->record[$this->current_field]=$text;

		}

	}

	function show_menu()

	{

		echo "<table border='1'>\n";

		foreach($this->records as $book){

			echo "<tr>";

			$authors=join(',',$book['author']);

			printf("<th><a href='%s'>%s</a></th><td>%s</td>\n",

			$_SERVER['PHP_SELF'].'?isbn='.$book['isbn'],

			$book['title'],

			$authors);

			echo "</tr>\n";

		}

		echo "</table>";

	}

	function show_book($isbn){

		$Find=false;

		foreach($this->records as $book){

			if($book['isbn']===$isbn){

				$author=join(',',$book['author']);

				printf("<b>%s</b> by %s.<br>",$book['title'],$author);

				printf("ISBN:%s<br>",$isbn);

				printf("Comment:%s\n",$book['comment']);	

				$Find=true;			

				break;				

			}

		}

		if(!$Find)echo "<b style='color:red'>Can't find this book of '$isbn'</b>";

		echo '<p>Back to the <a href="'.$_SERVER['PHP_SELF'].'">list of books</a>.</p>';

	}

}



$lib=new BookList("book.xml");

if($_GET['isbn']){

	$lib->show_book($_GET['isbn']);

}

else{

	$lib->show_menu();

}
