我有一个名为 processDeleteForm() 的 PHP 函数，用于从名为 structure.xml 的 xml 文档中删除指定的节点。到目前为止我遇到的唯一问题是在 processDeleteForm() 中，它通过循环遍历父节点的每个子节点来搜索要删除的节点，并通过“名称”属性匹配它，但我没有'能够为循环获取正确数量的子节点，因此它在到达正确的节点之前停止。相关代码:
function processDeleteForm($dir, $filename)
{
echo "Processing delete request.<br/>";
echo "Request to delete ".$filename." from ".$dir.".<br/>";
$xmlDoc = new DOMDocument();
$xmlDoc->load("structure.xml");
$node = dirDOMNodeWritable($dir, $xmlDoc);
$target;
echo "Working directory has ".count($node->childNodes)." child(ren).<br/>";
for($x = 0; $x < count($node->childNodes); $x++)
{
if($node->childNodes->item($x)->getAttribute("name") == $filename)
{
$target = $node->childNodes->item($x);
echo "Target found.<br/>";
}
else
{
echo "Searching for target...<br/>";
}
}
if($target->getAttribute("type") != "directory")
{
$fstored = "uploads/".$target->childNodes->item(0)->wholeText;
unlink($fstored);
}
$node->removeChild($target);
$file = fopen("structure.xml", "w");
fwrite($file, $xmlDoc->saveXML());
}

*上面应该是一个xml文件的内容，但我不知道如何显示它。如果对在 stackoverflow 上格式化 xml 有更多了解的人可以修复它，我将非常感激。
查看负责创建名为“test01”、“test02”和“test03”的目录的代码可能也很有用:
function processNewForm($dir, $dirName, $readPrivs, $writePrivs)
{
$readString = "";
$writeString = "";
$dirOwner = $_SESSION["user"];
for($x = 0; $x < count($readPrivs); $x++)
{
$readString += $readPrivs[$x].",";
}
for($x = 0; $x < count($writePrivs); $x++)
{
$writeString += $writePrivs[$x].",";
}
$xmlDoc = new DOMDocument();
$xmlDoc->load("structure.xml");
$node = dirDOMNodeWritable($dir, $xmlDoc);
$newDir = $xmlDoc->createElement("directory");
$newDir->setAttribute("name", $dirName);
$newDir->setAttribute("owner", $dirOwner);
$newDir->setAttribute("read", $readString);
$newDir->setAttribute("write", $writeString);
$newDir->setAttribute("type", "directory");
$node->appendChild($newDir);
$file = fopen("structure.xml", "w");
fwrite($file, $xmlDoc->saveXML());
}
当前输出如下所示:
