只加載XPath搜索到XMLReader的內存？

-1

我可以以某種方式做到這一點嗎？ XMLReader是pull語法分析器，所以我期望他能給我提供我搜索的數據，但它會將整個文檔加載到內存中，然後從我的內存中給我提供搜索。只加載XPath搜索到XMLReader的內存？

此代碼：

$url = $this->buildUrl($name,$params); 
    $xml = ''; 

    $reader = new XMLReader(); 
    $reader->open($url); 
    $pathXML = ''; 
    $dom = new DomDocument(); 

    while($reader->read()) { 
     if ($reader->nodeType == XMLREADER::ELEMENT && $reader->localName == 'OddsList'){ 
      $xml = simplexml_import_dom($dom->importNode($reader->expand(),true)); 
      if(!is_null($this->getExpression())){ 
       $pathXML = $xml->xpath($this->getExpression()); 
      } 
     break; 
     } 

    } 

    var_dump($pathXML);

返回我：

我想以某種方式得到的只是飼料，其中博彩公司Interwetten開而不加載他人，只是跳轉到Interwetten開回我搜索進料端。這需要很多時間。

什麼是'$這個 - > getExpression（）'結果呢？ – mhall

/XMLSOCCER.COM/OddsList/Odds[contains(Bookmaker,'Interwetten'）] – user1814358

你還在搜索整個OddsList。嘗試使用XMLReader可以是這樣的：

$reader = new XMLReader(); 
$reader->open($url); 
$dom = new DomDocument(); 

// Find first occurrence of Odds 
while ($reader->read() && $reader->name !== 'Odds'); 

// Iterate Odds 
while ($reader->name === 'Odds'){ 
    $odds = simplexml_import_dom($dom->importNode($reader->expand(), true)); 

    // Process those having the correct Bookmaker child value 
    if ($odds->xpath('./Bookmaker[string()="Interwetten"]')) { 
     var_dump($odds); 
    } 

    // Move to the next one 
    $reader->next('Odds'); 
}

輸出：

object(SimpleXMLElement)#4 (6) { 
    ["FixtureMatch_Id"]=> 
    string(6) "346076" 
    ["Bookmaker"]=> 
    string(11) "Interwetten" 
    ["UpdatedDate"]=> 
    string(23) "2015-06-20T19:42:33.113" 
    ["Type"]=> 
    string(14) "Over/Under 2.5" 
    ["HomeOdds"]=> 
    string(4) "1.85" 
    ["AwayOdds"]=> 
    string(4) "1.75" 
} 
object(SimpleXMLElement)#4 (7) { 
    ["FixtureMatch_Id"]=> 
    string(6) "346076" 
    ["Bookmaker"]=> 
    string(11) "Interwetten" 
    ["UpdatedDate"]=> 
    string(23) "2015-06-20T19:42:31.397" 
    ["Type"]=> 
    string(3) "1X2" 
    ["HomeOdds"]=> 
    string(3) "1.8" 
    ["DrawOdds"]=> 
    string(3) "3.4" 
    ["AwayOdds"]=> 
    string(1) "4" 
}
