1、关于DOM

文件名：city.php

//实现将各地区的天气情况入库

<?php
header("content-type:text/html;charset=utf-8");
$dsn="mysql:dbname=news;host=127.0.0.1;charset=utf8";

$pdo=new PDO($dsn,$user,$psw);
$url = "http://flash.weather.com.cn/wmaps/xml/china.xml";
//创建对象
$dom=new DOMDocument();
//print_r($dom);die;
$dom->load($url);
//读取最外层的节点
$city=$dom->getElementsByTagName("city");
//print_r($city);die;
$len = $city->length;
for($i=0;$i<$len;$i++){
    $item = $city->item($i);
    $quName = $item->getAttribute("quName");
    //print_r($quName);die;
    $pyName = $item->getAttribute("pyName");

    //执行sql语句
    set_time_limit(0);//取消脚本执行时间限制
    $res = $pdo->exec($sql);
    
    //获取省份信息
    $dom1=new DOMDocument();
    @$dom1->load("http://flash.weather.com.cn/wmaps/xml/".$pyName.".xml");
    $citys=$dom1->getElementsByTagName("city");
    $leng = $citys->length;

        $windState = $item1->getAttribute("windState");
        $windDir = $item1->getAttribute("windDir");
        $windPower = $item1->getAttribute("windPower");
        $humidity = $item1->getAttribute("humidity");
        $time = $item1->getAttribute("time");
        $url = $item1->getAttribute("url");
        //var_dump($humidity);die;
        $sql1 = "insert into sheng(cityX,cityY,cityname,centername,fontColor,pyName,state1,state2,stateDetailed,tem1,tem2,temNow,windState,windDir,windPower,humidity,time,url)values('".$cityX."','".$cityY."','".$cityname."','".$centername."','".$fontColor."','".$pyName."','".$state1."','".$state2."','".$stateDetailed."','".$tem1."','".$tem2."','".$temNow."','".$windState."','".$windDir."','".$windPower."','".$humidity."','".$time."','".$url."')";
        set_time_limit(0);//取消脚本执行时间限制
        //$data = $pdo->exec($sql1);

        //获取市的天气信息
        $dom2=new DOMDocument();
        @$dom2->load("http://flash.weather.com.cn/wmaps/xml/".$pyName.".xml");
        $city1=$dom2->getElementsByTagName("city");
        $length = $city1->length;
        //print_r($length);
        for($s=0;$s<$length;$s++){
            $item2 = $city1->item($s);
            $cityX = $item2->getAttribute("cityX");

            set_time_limit(0);//取消脚本执行时间限制
            $data1 = $pdo->exec($sql2);
        }
    }
}

2、XML基于事件,循环出各地区天气信息：jiexi.php

<?php
header("content-type:text/html;charset=utf-8");
$file = 'http://flash.weather.com.cn/wmaps/xml/china.xml';
$stack = array();
 
function startTag($parser, $name, $attrs) 
{
    global $stack;
    $tag=array("name"=>$name,"attrs"=>$attrs);   
    array_push($stack,$tag);
}
 
function cdata($parser, $cdata)
 {
     global $stack,$i;
     if(trim($cdata))
     {     
        $stack[count($stack)-1]['cdata']=$cdata;    
     }
 }
 
function endTag($parser, $name) 
{
    global $stack;   
   $stack[count($stack)-2]['children'][] = $stack[count($stack)-1];
    array_pop($stack);
}
 
$xml_parser = xml_parser_create();
 xml_set_element_handler($xml_parser, "startTag", "endTag");
 xml_set_character_data_handler($xml_parser, "cdata");
 
$data = xml_parse($xml_parser,file_get_contents($file));
 if(!$data) {
    die(sprintf("XML error: %s at line %d",
 xml_error_string(xml_get_error_code($xml_parser)),
 xml_get_current_line_number($xml_parser)));
 }
 
xml_parser_free($xml_parser);
 
print("<pre>\n");
 print_r($stack);
 print("</pre>\n");
 ?>
