我想用php读取xml的三个值

Question

$xml = <<<xml
<?xml version="1.0" encoding="utf-8"?>
<xml><row expect="20140421005" opencode="5,7,3,1,5" opentime="2014-04-21 00:25:30" /><row expect="20140421004" opencode="9,4,7,4,5" opentime="2014-04-21 00:20:30" /><row expect="20140421003" opencode="3,4,4,3,9" opentime="2014-04-21 00:15:30" /><row expect="20140421002" opencode="7,0,2,9,4" opentime="2014-04-21 00:10:30" /><row expect="20140421001" opencode="6,3,8,3,1" opentime="2014-04-21 00:05:30" /><row expect="20140420120" opencode="6,9,3,5,3" opentime="2014-04-21 00:00:30" /><row expect="20140420119" opencode="7,7,0,7,2" opentime="2014-04-20 23:55:30" /><row expect="20140420118" opencode="8,9,4,6,9" opentime="2014-04-20 23:50:30" /><row expect="20140420117" opencode="1,1,2,4,0" opentime="2014-04-20 23:45:30" /><row expect="20140420116" opencode="4,3,8,1,0" opentime="2014-04-20 23:40:30" /></xml>
xml;
$doc = new DOMDocument();
$doc->loadXML($xml); //读取xml文件
$items = $doc->getElementsByTagName('row');
for ( $i  =  0 ;  $i  <  $items -> length ;  $i ++) {
$t1 = $items -> item ( $i )->getAttribute('expect');//expect的值
    $t2 = $items -> item ( $i )->getAttribute('opencode');//opencode的值
    $t3 = $items -> item ( $i )->getAttribute('opentime');//opentime的值
    var_dump($t1.'|'.$t2.'|'.$t3);
}

Answer 1

经测试，你的代码没有问题
问题在于 $doc->load($url); 取不到值
该 url 用 file_get_contents 也取不到值
只有用 curl 才可取到取到后可用 $doc->loadXML($str) 载入
然后就可用你的代码处理了

$url = "http://www.cailele.com/static/ssc/newlyopenlist.xml";
$doc = new DOMDocument();
$doc->loadXML(curl_get($url));
$lst = $doc->getElementsByTagName('row');
for ($i=0; $i<2; $i++) {
  $iframe= $lst->item($i);
  $t1=$iframe->attributes->getNamedItem('expect')->value;
  $t2=$iframe->attributes->getNamedItem('opencode')->value;
  $t3=$iframe->attributes->getNamedItem('opentime')->value;
  $t1=substr($t1,-9);
  kjdata($t2,1,$t1,$t3);
}function kjdata() {
  echo join(', ', func_get_args()), PHP_EOL;
}function curl_get($durl) {
  $cookiejar = realpath('cookie.txt');
  $t = parse_url($durl);
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL,$durl);
  curl_setopt($ch, CURLOPT_TIMEOUT,5);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
  curl_setopt($ch, CURLOPT_REFERER, "http://$t[host]/");
  curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiejar);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
  $r = curl_exec($ch);
  curl_close($ch);
  return $r;
}
5,9,6,4,2, 1, 140421023, 2014-04-21 01:55:30
7,6,4,2,4, 1, 140421022, 2014-04-21 01:50:30

Answer 3

$url = "http://www.cailele.com/static/ssc/newlyopenlist.xml";
$doc = new DOMDocument();
$doc->loadXML(curl_get($url));
$lst = $doc->getElementsByTagName('row');
for ($i=0; $i<2; $i++) {
  $iframe= $lst->item($i);
  $t1=$iframe->attributes->getNamedItem('expect')->value;
  $t2=$iframe->attributes->getNamedItem('opencode')->value;
  $t3=$iframe->attributes->getNamedItem('opentime')->value;
  $t1=substr($t1,-9);
  kjdata($t2,1,$t1,$t3);
}function kjdata() {
  echo join(', ', func_get_args()), PHP_EOL;
}function curl_get($durl) {
  $cookiejar = realpath('cookie.txt');
  $t = parse_url($durl);
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL,$durl);
  curl_setopt($ch, CURLOPT_TIMEOUT,5);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
  curl_setopt($ch, CURLOPT_REFERER, "http://$t[host]/");
  curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiejar);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
  $r = curl_exec($ch);
  curl_close($ch);
  return $r;
}这样也还是读不到。
