Question

我正在使用API并以下面的形式返回XML，需要一些专家帮助：

我正在使用像这样的卷曲

<?php

header('Content-Type: text/xml');
$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://api.info',
    CURLOPT_USERPWD => "user",
    CURLOPT_ENCODING => 'pass',
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_RETURNTRANSFER => true));

$responseData = curl_exec($curl);

if(curl_errno($curl))
{
    $errorMessage = curl_error($curl);
    // TODO: Handle cURL error
}
else
{
    $statusCode = curl_getinfo($curl, CURLINFO_HTTP_CODE); 
    // TODO: Handle HTTP status code and response data
    print $responseData;
}

curl_close($curl);
?>

print $responseData;会返回您在上面看到的XML。我想将其转换为数组或能够提取类似于

的单个值

<?php
include 'example.php';

$movies = new SimpleXMLElement($xmlstr);

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

在http://php.net/manual/en/simplexml.examples-basic.php

我得到XML解析错误：格式错误且XML解析错误：找不到根元素错误。

由于

当您知道输入是有效的XHTML时，SimpleXML是一个选项。如果你需要解析破碎/非严格的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，但是当您尝试使用SimpleXml解析非严格的XHTML时，会发生您所指的错误not well-formed and XML Parsing Error: no root element found errors.。请改用DOMDocument。例如，

$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";
}

将对您提供的样本进行处理，打印

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

虽然粗略等同于你的

$movies = new SimpleXMLElement($xmlstr);

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

代码将是：

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

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

XML到数组使用PHP但返回错误
