Question

我又遇到了一个问题，目前XML并不适合我...... 为什么我收到此错误消息以及如何解决？

我收到每个XML文件的错误消息！

错误讯息：

PHP Warning:  DOMDocument::loadXML(): Start tag expected, '<' not found in Entity, line: 1 in C:\Users\Jan\PhpstormProjects\censored\Matcher.php on line 36
Warning: DOMDocument::loadXML(): Start tag expected, '<' not found in Entity, line: 1 in C:\Users\Jan\PhpstormProjects\censored\Matcher.php on line 36

代码：

function loadTitlesIntoArray($tagName, $path){

$dom = new DOMDocument('1.0', 'utf-8');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($path);

$titels = array();
$marker = $dom->getElementsByTagName($tagName);

for ($i = $marker->length - 1; $i >= 0; $i--) {
    $new = $marker->item($i)->textContent;
    array_push($titels, $new);
}

print_r($titels);
}

loadTitlesIntoArray（＆＃39; title＆＃39;，$ kinguinPath）;

XML：

<?xml version="1.0" encoding="UTF-8"?>

问候，谢谢！

Answer 1

loadXML期待string of XML但你试图给它一个文件路径。试试load。或者，您可以将XML文件加载到字符串中，然后调用loadXML。

Answer 2

某些RSS与PHP中的DOM使用的libxml不完全兼容。要解决此问题，您可以像这样扩展您的功能：

function loadTitlesIntoArray($tagName, $path){

  // load XML into simplexml
  $xml = simplexml_load_file( $path );

  // if the XML is valid
  if ( $xml instanceof SimpleXMLElement ) {

    $dom = new DOMDocument( '1.0', 'utf-8' );
    $dom->preserveWhiteSpace = false;
    $dom->formatOutput = true;

    // use it as a source
    $dom->loadXML( $xml->asXML() );

    $titels = array();
    $marker = $dom->getElementsByTagName( $tagName );

    for ( $i = $marker->length - 1; $i >= 0; $i-- ) {
      $new = $marker->item( $i )->textContent;
      array_push( $titels, $new );
    }

    print_r( $titels );
  }
}

DOMDocument :: loadXML（）：期望开始标记：＆＃34;＆lt;＆＃34;
