由于StackOverflow社区的帮助,修改了与jsTree一起使用的复杂XML源,我取得了一些成功。但是现在我有可用的数据,只有当我手动编辑XML才能执行以下操作时:
<user>
代码重命名为<item>
<user>
代码'encoding=UTF-8'
插入XML opener <response>
(打开XML标记)修改为<root>
XML文件示例:SampleXML
我已阅读并阅读了这么多页面和谷歌但找不到实现上述项目的方法。
点(2)我发现通过SimpleXML加载并使用UNSET
我可以删除我不需要的部分,但我仍然有其余的麻烦。
我想我可以用SimpleXML(我更熟悉)来修改源代码,然后通过之前提供的帮助继续修改代码。
<?php
$s = file_get_contents('http://www.fluffyduck.com.au/sampleXML.xml');
$doc1 = simplexml_load_string($s);
unset($doc1->row);
unset($doc1->display);
#$moo = $doc1->user;
echo '<textarea>';
echo $doc1->asXML();
echo '</textarea>';
$doc = new DOMDocument();
$doc->loadXML($doc1);
$users = $doc->getElementsByTagName("user");
foreach ($users as $user)
{
if ($user->hasAttributes())
{
// create content node
$content = $user->appendChild($doc->createElement("content"));
// transform attributes into content elements
for ($i = 0; $i < $user->attributes->length; $i++)
{
$attr = $user->attributes->item($i);
if (strtolower($attr->name) != "id")
{
if ($user->removeAttribute($attr->name))
{
if($attr->name == "username") {
$content->appendChild($doc->createElement('name', $attr->value));
} else {
$content->appendChild($doc->createElement($attr->name, $attr->value));
}
$i--;
}
}
}
}
}
$doc->saveXML();
header("Content-Type: text/xml");
echo $doc->saveXML();
?>

使用递归,您可以根据输入创建一个全新的文档,一次解决所有问题:
<强>代码强>
<?php
$input = file_get_contents('http://www.fluffyduck.com.au/sampleXML.xml');
$inputDoc = new DOMDocument();
$inputDoc->loadXML($input);
$outputDoc = new DOMDocument("1.0", "utf-8");
$outputDoc->appendChild($outputDoc->createElement("root"));
function ConvertUserToItem($outputDoc, $inputNode, $outputNode)
{
if ($inputNode->hasChildNodes())
{
foreach ($inputNode->childNodes as $inputChild)
{
if (strtolower($inputChild->nodeName) == "user")
{
$outputChild = $outputDoc->createElement("item");
$outputNode->appendChild($outputChild);
// read input attributes and convert them to nodes
if ($inputChild->hasAttributes())
{
$outputContent = $outputDoc->createElement("content");
foreach ($inputChild->attributes as $attribute)
{
if (strtolower($attribute->name) != "id")
{
$outputContent->appendChild($outputDoc->createElement($attribute->name, $attribute->value));
}
else
{
$outputChild->setAttribute($attribute->name, $attribute->value);
}
}
$outputChild->appendChild($outputContent);
}
// recursive call
ConvertUserToItem($outputDoc, $inputChild, $outputChild);
}
}
}
}
ConvertUserToItem($outputDoc, $inputDoc->documentElement, $outputDoc->documentElement);
header("Content-Type: text/xml; charset=" . $outputDoc->encoding);
echo $outputDoc->saveXML();
?>
