GetElementsByTagName format filter (need urgent help)

Question

I'm trying to format a NodeList obtained via getElementsByTagName, actually I can get the content of each tag, but I can't filter, I'm trying to make the output like this:

EXAMPLE:

name: jhon doe
number: 12345678
date: 00/00/0000

But I only get normal content:

JOHN DOE
12345678
00/00/0000
lane DOE
7234567890
00/30/0000

Or if I use [0], it only returns the first letter/number of each tag.

J
1
0
l
7
3

My current code is below, any tips on what I can do?

<?php
$string = '
<tbody>
<tr>
<td>JOHN DOE</td>
<td style="background-color: rgb(25, 194, 25);">12345678</td>
<td>00/00/0000</td>
</tr>
<tr>
<td>lANE DOE</td>
<td style="background-color: rgb(25, 194, 25);">7234567890</td>
<td>30/00/0000</td>
</tr>
</tbody>';
$dom = new DOMDocument();
$dom->loadHTML($string);
foreach($dom->getElementsByTagName('td') as $td) {
    echo $td->textContent[0] . '<br/>';
}

Answer 1

The mistake you made is that you used the td tag, which does not return every record but every value (see your code).

First you should use the "tr" tag

Secondly, you should use nodeValue to get the data for any specific item by mentioning the index

The corrected code is given for your reference. If you have any questions, please feel free to ask questions

JOHN DOE
12345678
00/00/0000


lANE DOE
7234567890
30/00/0000

';
$dom = new DOMDocument();
$dom->loadHTML($string);
$tr = $dom->getElementsByTagName('tr');
echo $tr->item(0)->nodeValue;

If you want to output all items, you can simply use a loop

Answer 2

Where do you expect name, number and date to come from? PHP has no idea what the table values ​​mean, so you have to set them yourself somehow.

There is no indication in HTML what each table cell means, so you can only guess and hope that the table structure never changes. The tables are sorted by name - number - date, so you can deduce from the cell numbers that the label for a specific must be: 0 = name, 1 = number, 2 = date.

So if you parse the HTML for each table row , and then parse each row for each table cell , you can add tags based on cell order.

But please note that if the content of the HTML comes from an external source and they change the order of the cells, an error will occur.

//create an array of labels, based on the cell order per row
$labels=[
    0=>'name',
    1=>'number',
    2=>'date'
    ];

$dom = new DOMDocument();
$dom->loadHTML($string);

// search for table ROWS
$table_rows = $dom->getElementsByTagName('tr');

//loop the ROWS
foreach($table_rows as $row){
   //per ROW node, search for table CELLS
   $row_cells = $row->getElementsByTagName('td');
   //loop the CELLS
   foreach($row_cells as $number => $cell){
     //echo a label based on the cell order + the contents of the cell
     echo $labels[$number].' - '.$cell->textContent.'
';
    }
}
