How can I exclude first <tr>
Question by mustafa
With php dom, I am getting all TRs and TDs inside.
<?PHP
foreach($table->getElementsByTagName('tr') as $tr){
echo $tr->getElementsByTagName('td')->item(0)->nodeValue);
}
?>
Can we exclude the first tr and its tds.
Answer by Michael Berkowski
I think the node list is numerically indexed (though I cannot test it), so using a key in the foreach may work:
foreach($table->getElementsByTagName('tr') as $key => $tr){
// Don't act on the first element
if ($key > 0) {
echo $tr->getElementsByTagName('td')->item(0)->nodeValue);
}
}

Compare the index of elements, if its first and use continue the to skip the loop.
<?PHP
foreach($table->getElementsByTagName('tr') as $index => $tr){
if($index == 0) { continue; }
echo $tr->getElementsByTagName('td')->item(0)->nodeValue);
}
?>
