Question

我正在尝试将HTML文件中的表读入数组，我被卡住了。任何帮助将不胜感激。

每个表元素都应存储在1个数组值

中

示例：$arr[1]= DER HE1 ges 1

PHP

<?php
      libxml_use_internal_errors(true);
      $i=0;
      // new dom object  
      $dom = new DOMDocument();  

      //load the html  
      $html = $dom->loadHTMLFile("106642new.html");  

      //discard white space   
      $dom->preserveWhiteSpace = false;   

      //the table by its tag name  
      $tables = $dom->getElementsByTagName('table');   

      //get all rows from the table  
      $rows = $tables->item(0)->getElementsByTagName('tr');   
      // $test = $tables->item(0)->getElementsByTagName('td');   

      // loop over the table rows  
      foreach ($rows as $row) {
          // get each column by tag name  
          $cols = $row->getElementsByTagName('td');  
          $i= $i + 1 ;
          $value = "Nummer: ".$i.":  ".$cols->item(0)->nodeValue.PHP_EOL;
          // $value = "test: ".$i.":  ".$cols->item(0)->nodeValue.PHP_EOL;
          $cols = array(1, 2, 3, 4, 5);
          echo $value;
          //  $cols[$i] = $row; 
          // echo the values    
          //echo $cols->item(0)->nodeValue ; 
      }   
?>

Answer 1

如果认为问题是你的第一个表是其他表的容器。如果你想获得所有表的内容，那么你也应该遍历表列表。

如果您只想获取内部表的内容，请先尝试在DOM中找到它。我建议找到第一个表，而不是在其中查找所有表元素并迭代它们。

var_dump是调试的一个很好的起点，你不需要你已经做过的任何其他事情，只需调试和测试更多：）

Answer 2

我猜测它是无效的HTML / XML这一事实让你搞砸了。

您正在使用loadHTMLFile（）函数，该函数可能在某种程度上支持格式错误的HTML，但它可能还需要有效的HTML / XML。

如果它需要有效的XML，那么可能发生的是“＆lt; br＆gt;”不会被解释为独立节点，而是被解释为节点的起点...意味着之后的所有内容都成为“＆lt; br＆gt;”的子节点。

此外这一行没有任何意义：

<p font class="Header">Basisrooster schooljaar 2011 2012 (m.i.v. 12-09-11)</font></p>

＆lt; font＆gt;标签已经过时多年，绝不应该使用，但更重要的是它不是字体标签而是p标签，它仍然会被关闭，就像它是一个字体标签一样。只是做：

<p class="Header">Basisrooster schooljaar 2011 2012 (m.i.v. 12-09-11)</p>

因此解决方案可能是您的HTML / XML无效。

（Dan Bizdadea也有一个很好的观点。）
