幫助，打印HTML表使用PHP DOM文檔

我想使用PHP DOM文檔，但掙扎 我也跟下面把代碼寫在我們的網頁打印此HTML代碼。你可以幫我嗎。

</table>

我已經寫了這段代碼，但它沒有得到正確的。 外部foreach循環運行17次，但應該只有兩次，因爲外部表只有兩行。

$xml = new DOMDocument(); 
$xml->validateOnParse = true; 
$xml->loadHTMLFile($url); 

$xpath = new DOMXPath($xml); 

$table =$xpath->query("//*[@id='machine']")->item(0); 

echo "<table border=2>"; 
$rows = $table->getElementsByTagName("tr"); 

foreach ($rows as $row) //there i only two rows. 
{ 
echo "<tr>"; 
    $cells = $row -> getElementsByTagName('td'); 

    foreach ($cells as $cell) 
    { 
    echo "<td>"; 
    foreach ($cell->getElementsByTagName('table') as $innerTable) 
    { 
     foreach ($innerTable->getElementsByTagName("tr") as $innerTrs) 
     { 
     foreach ($innerTrs->getElementsByTagName('td') as $innerCell) 
     { 
      foreach ($innerCell->getElementsByTagName('a') as $a) 
      { 
       echo '<br><a href="'.GetMainBaseFromURL($url).$a->getAttribute('href').'">'.$a->nodeValue.'</a>'; 

       foreach ($a->getElementsByTagName('img') as $img) 
       echo '<br><a href="'.GetMainBaseFromURL($url).$a->getAttribute('href').'"> <img src="'.GetMainBaseFromURL($url).$img->getAttribute('src').'"></a>'; 
      }   
     } 
     } 
    } 

    echo "</td>"; 
    } 
    echo "</tr>"; 
} 
echo "</table>";

那麼我怎麼能打印，因爲它是我的網頁中的HTML表使用PHP DOM文檔。 我是新的PHP DOM。

謝謝。 非常感謝。

什麼不起作用？你有什麼錯誤嗎？ – hakre

沒有得到錯誤，但它僅打印內部html表格數據，而不打印外部表格內部但在內部html表格外部的外部數據。 – Bajrang

然後，我必須寫這個？第一個tr的數據不是打印。 – Bajrang

僅僅因爲您在發佈的HTML代碼中有17個標籤，foreach循環才迭代17。 其實$ rows = $ table-> getElementsByTagName（「tr」）;提取樹中任意深度的任何標籤。

，僅保留兩個外，你可以這樣做

$ TBODY = $表 - >的childNodes;

$ outerTr = $ tbody-> childNodes;

的上$ outerTr的迭代

您也可以建立一個XPath表達式只得到兩個外

我沒有然而，測試YOUT代碼在別人的foreach，記住了同樣的問題的getElementsByTagName（ 「TR」）（或其他標籤TD，一..）的

如果你只是想複製的表，你可以這樣做：

<?php 
$xml = new DOMDocument(); 
$xml->validateOnParse = true; 
$xml->loadHTMLFile($url); 

$table = $xml->getElementById('machine'); 
echo $xml->saveXML($table); 
?>

getElementsByTagName適用於整個文檔。該文檔有17 tr個元素，因此無論放置哪個元素，它都會返回它們。

當你想尋找具體tr元素，或特定表內的圖像更具體，我建議你讓XPath的做的大部分工作：

$xpath = new DOMXPath($xml); 

$nodes =$xpath->query("//table[@id='machine']/tbody/tr/td/div/a/img"); 

echo 'Found ', $nodes->length, ":\n"; 

foreach($nodes as $node) 
{ 
    $img = $node; 
    $a = $node->parentNode; 
    $aHref = $a->getAttribute('href'); 
    $imgSrc = $img->getAttribute('src'); 
    printf("Element:\n + href: %s;\n +- src: %s\n\n", $aHref, $imgSrc); 
}

這將列出3個元素已經（不2）。你需要進一步決定哪些放棄，但這應該更容易。 Demo &輸出：

Found 3: 
Element: 
+ href: /photos.php?id=7135&p=1; 
+- src: /class/class_Image.php?load=cGhvdG9zL0ExMTk0LmpwZ3wyNTB8MjUwfDF8 

Element: 
+ href: /photos.php?id=7135&p=2; 
+- src: /class/class_Image.php?load=cGhvdG9zL0ExMTk0XzEuanBnfDI1MHwyNTB8MXw= 

Element: 
+ href: /machine-print.php?id=7135; 
+- src: http://www.sterlingmachinery.com/images/quick_quote.jpg

另一個提示：一歸一化數據到像陣列的結構。然後你可以使用你的數組來生成輸出。這樣做可以將輸出中的解析分開，這將使您更容易實現目標。

  • 將文檔解析爲數組。
  • 修改您在該陣列中需要的值（例如GetMainBaseFromURL）。
  • 基於數組生成輸出。
