</table>
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>";
Then how can i print as it is html table in my web page using php dom document. I am new in php dom.
Thank you. Thanks a lot.
回答1:
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.
To get only the two outer you can do something like
$tbody = $table->childNodes;
$outerTr = $tbody->childNodes;
An the iterate on $outerTr
You can also build an Xpath expression to get only the two outer
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 ..)
回答2:
getElementsByTagName works on the whole document. The document has 17 tr elements, so it will return them all regardless where those are placed.
As you want to look for specific tr elements, or more specifically for images inside a specific table, I suggest you let xpath do most of the work:
$xpath = new DOMXPath($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);
}
This will list 3 elements already (not 2). You need to further on decide which ones to drop, but this should make it more easy. Demo & Output:
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
Another tip: First normalize your data into a structure like an array. You can then use your array to generate the output. That done you can separate the parsing from the output which will make it more easy for you to achieve your goals.
- Parse the document into an array.
- Modify values as you need them in that array (e.g.
GetMainBaseFromURL). - Generate the output based on the array.
回答3:
If you just want to copy the table you can do this:
<?php
$xml = new DOMDocument();
$xml->validateOnParse = true;
$xml->loadHTMLFile($url);
$table = $xml->getElementById('machine');
echo $xml->saveXML($table);
?>
