我已经写了这段代码，但没有正确。
外部foreach循环运行17次，但应该只有两次，因为外表只有两行。
I have write this code but its not getting properly. Outer foreach loops runs 17 times but should be only two time because the outer table has only two rows.
$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).$img->getAttribute('src').'"></a>';
}
}
}
}
echo "</td>";
}
echo "</tr>";
}
echo "</table>";
然后我如何打印，因为它是html表在我的网页使用php dom文档。
我在php dom中是新的。
Then how can i print as it is html table in my web page using php dom document. I am new in php dom.
谢谢。
非常感谢。
Thank you. Thanks a lot.
推荐答案
foreach循环迭代17，只因为你发布的HTML代码中有17个标签。
实际上$ rows = $ table-> getElementsByTagName（tr）;提取树中任何深度的任何标签。
The foreach loop iterates 17 just because you have 17 tags in the HTML code you posted. Actually the $rows = $table->getElementsByTagName("tr"); extracts any tag at any depth in the tree.
要只得到两个外部你可以做一些像
To get only the two outer you can do something like
$ tbody = $ table-> childNodes;
$tbody = $table->childNodes;
$ outerTr = $ tbody-> childNodes;
$outerTr = $tbody->childNodes;
$ outerTr
An the iterate on $outerTr
上的迭代您还可以构建一个Xpath表达式，只得到两个外部
You can also build an Xpath expression to get only the two outer
不要测试yout代码，但在其他的foreach中，请记住getElementsByTagName（tr）（或其他标签td，a ..）相同的问题。
I did not test yout code however, in the others foreach, keep in mind the same problem of getElementsByTagName("tr") (or other tags td,a ..)
