在XML PHP Xpath上寻求帮助

问题描述

$Result = $objXML->xpath(''AllRelease/Release/name[@rdate="''.$DATERELEASE.''"]'');

if(empty($Result)){
    $AllRelease = $objXML->xpath("//AllRelease");
    $releas = $AllRelease[0]->prependChild2("Release");
    $dat = $releas->prependChild2("name");
    $dat->addAttribute("rdate",$DATERELEASE);
    $releas->prependChild("comment",$COMMENT);
    $Anime = $releas->prependChild2("Anime");
    $Anime->prependChild("popup",$POPUP);
    $Anime->prependChild("Title",$VIDEONAME);
    $Anime->prependChild("VideoUrl",$dir);
    $objXML->asXML("MainRelease.xml");
}else{
    $Anime = $objXML->xpath("//Release");
    $anime = $Anime[0]->addChild("Anime");
    $anime->addChild("popup",$POPUP);
    $anime->addChild("Title",$VIDEONAME);
    $anime->addChild("VideoUrl",$dir);
    $objXML->asXML("MainRelease.xml");	
}

我执行了此操作，并且$ Result在任何情况下总是让我为空，因此基本上他不会执行第二条声明xpath不起作用，因为我第一次使用xpath，simplexml，xml不能完全确定，<

i did this and $Result always giving me empty in any condition so basically he won''t do the second statement the xpath not working im not really sure since its first time i working with xpath, simplexml, xml any help would be appreciate
