Arrays 使用PHP将XML转换为数组，但返回错误

我正在使用API并以以下形式返回XML，需要一些专家帮助：

我得到XML解析错误：格式不正确，XML解析错误：未找到根元素错误

谢谢

当您知道输入是有效的XHTML时，SimpleXML是一个选项。如果需要解析不完整/不严格的XML/HTML，甚至不要考虑SimpleXml，因为它会阻塞。另一方面，DOMDocument在解析非严格有效的XHTML方面要好得多。现在，您提供的示例输入实际上是有效的XML，但您所指的错误是，

格式不正确，并且XML解析错误：未找到根元素错误。

在尝试使用SimpleXml解析非严格XHTML时发生。改用DOMDocument。比如说,

$domd = @DOMDocument::loadHTML ( $xml );
$xp = new DOMXPath ( $domd );
foreach ( $domd->getElementsByTagName ( "record" ) as $record ) {
    $interesting = $xp->query ( './/prefix|.//fname|.//email', $record );
    foreach ( $interesting as $ele ) {
        echo "{$ele->nodeName}: {$ele->textContent}\n";
    }
    echo "-\n";
}

将处理您提供的样品，打印

prefix: Ms.
fname: Mark
email: mabbotto@site.net
-
prefix: Ms.
fname: Traci
email: jdoe@mysite.com
-

而粗糙相当于你的

$movies = new SimpleXMLElement($xmlstr);

echo $movies->movie[0]->plot;

代码为：

$movies=@DOMDocument::loadHTML($xmlstr);

echo $movies->getElementsByTagName("movie")->item(0)->getElementsByTagName("plot")->item(0)->textContent;

可能是重复的谢谢。非常感谢

$movies = new SimpleXMLElement($xmlstr);

echo $movies->movie[0]->plot;

$movies=@DOMDocument::loadHTML($xmlstr);

echo $movies->getElementsByTagName("movie")->item(0)->getElementsByTagName("plot")->item(0)->textContent;
