保存没有声明的XML文件 - 具有特定地址

Question

我试图找到一种方法来保存编辑后的XML文件，而不包括声明。但我需要能够设置一个地址。因为我正在保存原始XML，并保存在临时位置之一（原件的副本用于访问javascript，因为原始位于本地文件中）。

所以我尝试了$ dom-＆gt; saveXML（$ xml-＆gt; documentElement）;但是出现了一些保存错误。 这是获取表单数据并将其保存到当前加载的xml的php页面，然后保存它和另一个副本（在下面的代码底部）

<?php
//header('Location: ../index.php' );

$dom = new DOMDocument();
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->load("../data/fileloc.xml");

$fileUrlTag = $dom->getElementsByTagName('fileurl')->item(0);
$fileName = $fileUrlTag->getAttribute('filename');
$fileAddress = $fileUrlTag->getAttribute('address');
$fileUrl = $fileAddress.$fileName;


if(isset($_REQUEST['ok'])){
    $xml = new DOMDocument();
    $xml->preserveWhiteSpace = false;
    $xml->formatOutput = true;
    $xml->load($fileUrl);

    //checks if Objects tag exists
    $rootTag = $xml->getElementsByTagName("Objects")->item(0);

    //if Objects tag doesnt exist, creates it and a unique id
    if($xml->getElementsByTagName("Objects")->length == 0){
        $rootTag = $xml->createElement("Objects");
        $alph = "0123456789ABCDEF";
        $ranStr = '';
        for($i=0;$i<32;$i++){
            if($i==8 || $i==12 || $i==16 || $i==20){
                $ranStr .= "-";
            }
            $pos = rand(0,35);
            $ranStr .= $alph[rand(0, strlen($alph)-1)];
            };
        $randId = "{".$ranStr."}";
        $rootTag->setAttribute("OverlayId",$randId);

        $objDocTag = $xml->getElementsByTagName("ObjectsDoc")->item(0);

        if($objDocTag->getAttribute("Version")->length == 0){
                $objDocTag->setAttribute("Version","1.0");
        };

        $objDocTag->appendChild($rootTag);
    };




    //used to set ID on Layer tag - gets value from the Objects->OverlayId attribute
    $getId = $rootTag->getAttribute('OverlayId');
    //used to set ID on Object tag
    $numObj = $xml->getElementsByTagName('Object')->length;

    //commstag determines colours for Pen and Brush tags
    $commsTag = $xml->createElement("comms",$_REQUEST["comms"]);


    //convert from deg to radians
    $lat = $_REQUEST['lat'];
    $long = $_REQUEST['long'];
    $latRad = ($lat*6.28318)/360;
    $longRad = ($long*6.28318)/360;
    if($_REQUEST['comms']=='Good'){
        $color = array(255,0,255,0);
    };
    if($_REQUEST['comms']=='Bad'){
        $color = array(255,0,255,255);

                            $brushTag = $xml->createElement('Brush');
                                $brushTag->setAttribute('A',$color[0]);
                                $brushTag->setAttribute('B',$color[1]);
                                $brushTag->setAttribute('FillStyle',10);
                                $brushTag->setAttribute('G',$color[2]);
                                $brushTag->setAttribute('R',$color[3]);

    //Append RefCoordinate and Coordinate to Coordinates

    $graphicPrimTag->appendChild($fontTag);
    //Append Layer, GraphicPrimitive, Coordinates to Graphic
    $graphicTag->appendChild($layerTag);
    $graphicTag->appendChild($graphicPrimTag);
    $graphicTag->appendChild($coordsTag);
    //Append Graphic to Object
    $objectTag->appendChild($graphicTag);
    $objectTag->appendChild($accessTag);
    //Append Object to Objects
    $rootTag->appendChild($objectTag);

    echo($fileUrl);
    $xml->save($fileUrl);
    $xml->save("..temp/".$fileName);
    exit();
};

我尝试运行这些（第一个保存到我假设的$ xml加载的位置？第二个到javascript的临时文件夹 - 第二个可以有声明）。

$xml->saveXML($xml->documentElement);
$xml->save("..temp/".$fileName);

但是下面会出现这个错误

Warning: DOMDocument::save(..temp/bms_overlays.xml) [domdocument.save]: failed to open stream: No such file or directory in D:\Programs\server2go\htdocs\analyst\scripts\createcontent.php on line 152

任何帮助都会非常感激，因为这是我第一次玩php和xml。

干杯，
