我有一个html表,我想将其列转换为行。列可以包含计划文本,表单元素(输入,选择,复选框)或html标记(span,div)。请考虑以下html:
<html>
<body>
<table>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
</tr>
<tr>
<td>Cell 4</td>
<td>Cell 5</td>
<td>Cell 6</td>
</tr>
</table>
</body>
</html>
在dom操作之后我需要以下内容:
<html>
<body>
<table>
<tr>
<td>Cell 1</td>
</tr>
<tr>
<td>Cell 2</td>
</tr>
<tr>
<td>Cell 3</td>
</tr>
<tr>
<td>Cell 4</td>
</tr>
<tr>
<td>Cell 5</td>
</tr>
<tr>
<td>Cell 6</td>
</tr>
</table>
</body>
</html>
$rows = $xpath->query('xpath to table/tr');
foreach ($rows as $row){
$cols = $xpath->query('xpath to table/tr/*');
$row->parentNode->removeChild($row);
foreach ($cols as $col){
$newNode = $this->createElement('tr');
$newNode->appendChild($col);
$node->appendChild($newNode);
}
}
echo $dom->saveHTML();
它的工作正常,但它添加了空行:
<table>
<tr></tr>
<tr></tr>
<tr>
<td>Cell 1</td>
</tr>
<tr>
<td>Cell 2</td>
</tr>
<table>
我知道我做错了吗?

您可以使用DOM解析HTML和XML,这就是您可以阅读表的方法:
$dom = new DOMDocument;
$dom->loadHTML( $table );
$tds = array();
foreach( $dom->getElementsByTagName( 'td' ) as $td ) {
$tds[] = $td->nodeValue;
}
打印展平的结构:
foreach($tds as $td){
print '<td>'.$td.'</td>';
}

您可以将每个<td>
元素移动到其当前祖先<tr>
元素的新<table>
子元素中:
foreach($xpath->query('//td') as $td)
$xpath->query('ancestor::table[1]', $td)->item(0)
->appendChild($doc->createElement('tr'))->appendChild($td);
{{;;}}
之后,您可以删除所有没有<tr>
个孩子的所有<td>
元素:
foreach($xpath->query('//tr[0 = count(td)]') as $tr)
$tr->parentNode->removeChild($tr);
{{;;}}
您的文档现已转换:
<table>
<tr><td>Cell 1</td></tr>
<tr><td>Cell 2</td></tr>
<tr><td>Cell 3</td></tr>
<tr><td>Cell 4</td></tr>
<tr><td>Cell 5</td></tr>
<tr><td>Cell 6</td></tr>
</table>
