How to combine two table cells in the same table row? - php

How can I merge the date td/cell into the time td/cell?
I would like the table row to consist of 3 cells, the middle cell should read date time.
My Code:
$dom = new DOMDocument;
$dom->loadHTMLFile("test.html");
$dom->validateOnParse = true;
$xpath = new DOMXPath($dom);
$table = $xpath->query("//*[#class='mytable']//tbody")->item(0);
$td = $table->getElementsbytagname("td");
test.html file contents:
<table class="mytable">
<tbody><tr>
<td>date</td>
<td>td1</td>
<td>time</td>
<td>td2</td>
</tr></tbody>
</table>
Desired result:
<table class="mytable">
<tbody><tr>
<td>td1</td>
<td>date time</td>
<td>td2</td>
</tr></tbody>
</table>


Collect the tbody tr cells. Overwrite the 3rd occurring cell's text using the 1st occurring cell' text, then delete the first cell.
Code (Demo)
$html = <<<HTML
<table class="mytable">
<tbody><tr>
<td>date</td>
<td>td1</td>
<td>time</td>
<td>td2</td>
</tr></tbody>
</table>
HTML;
$dom = new DOMDocument;
$dom->loadHTML($html, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
$xpath = new DOMXPath($dom);
foreach ($xpath->query("//table[#class='mytable']/tbody/tr") as $tr) {
$tds = $tr->getElementsByTagName("td");
$tds->item(2)->nodeValue = $tds->item(0)->nodeValue .
' ' . $tds->item(2)->nodeValue;
$tr->removeChild($tds->item(0));
}
echo $dom->saveHTML();
Output:
<table class="mytable">
<tbody><tr>
<td>td1</td>
<td>date time</td>
<td>td2</td>
</tr></tbody>
</table>

php get dom html elements

I have some PHP code which returns the HTML content from another file:
$html = file_get_contents('myFile.html');
$dom = new DOMDocument();
$dom->loadHTML($html);
This is a part of the content of $html:
<table class="content_table">
<tbody>
<tr>
<td>Value1</td>
<td>Value2</td>
<td>Value3</td>
</tr>
<tr>
<td>Value1</td>
<td>Value2</td>
<td>Value3</td>
</tr>
</tbody>
</table>
My question:
How can I get all the values of <td> where the table tag has the class "content_table"?

The following query looks for table element that has content_table class, then extracts the td values from it:
<?php
$html = '<table class="content_table">
<tbody>
<tr>
<td>Value1</td>
<td>Value2</td>
<td>Value3</td>
</tr>
<tr>
<td>Value1</td>
<td>Value2</td>
<td>Value3</td>
</tr>
</tbody>
</table>';
$dom = new DOMDocument('1.0', 'UTF-8');
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$data = [];
foreach($xpath->query('//table[#class="content_table"]') as $table) {
foreach($table->getElementsByTagName('td') as $td) {
$data[] = $td->nodeValue;
}
}
print_r($data);
Or if you need only td elements that have content_table class then it do the task:
foreach($xpath->query('//td[#class="content_table"]') as $td) {
$data[] = $td->nodeValue;
}
Example html:
$html = '<table class="content_table">
<tbody>
<tr>
<td>Value1</td>
<td class="content_table">Value2</td>
<td>Value3</td>
</tr>
<tr>
<td>Value1</td>
<td class="content_table">Value2</td>
<td>Value3</td>
</tr>
</tbody>
</table>';

Remove current node from HTML and fetch the final HTML using DOMDocument php

I have a html like below:
<table>
<thead>
<tr>
<th>Name</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<tr>
<td>ABC</td>
<td><a data-permission="allow"></a></td>
</tr>
<tr>
<td>B</td>
<td><a data-permission="allow"></a></td>
</tr>
<tr>
<td>C</td>
<td><a data-permission="allow"></a></td>
</tr>
<tr>
<td>D</td>
<td><a data-permission="allow"></a></td>
</tr>
<tr>
<td>E</td>
<td><button type="button" data-permission="allow"></button></td>
</tr>
</tbody>
</table>
Now i am finding the nodes who contains "data-permission" attributes like (a, button etc.) from above example.
TO do that i am using the below code. Now what i am trying do is remove that whole <a>..</a> or <button>...</button> or any other element if they contain "data-permission" attribute and after deletion only return remaining HTML. So how to achieve that?
$dom = new DOMDocument;
$dom->loadHTML($output);
$xpath = new DOMXPath($dom);
$nodes = $xpath->query('//#data-permission-id');
foreach ($nodes as $node) {
echo $node->nodeValue;
//$node->parentNode->removeChild($node); throws the error "Not Found Error"
}
Note- I have tried $node->parentNode->removeChild($node); inside loop, but it throws the error. Also after delete that tag, i want to get remaining HTML. I have read the How to delete element with DOMDocument? but it doesn't help.

Replace your node value to remove : $node->nodeValue = "";
$dom = new DOMDocument;
$dom->loadHTML($output);
echo "Previous : ".PHP_EOL.$dom->textContent.PHP_EOL;
$xpath = new DOMXPath($dom);
$nodes = $xpath->query("//*[#data-permission='allow']");
foreach ($nodes as $node) {
$node->nodeValue = "";
$dom->saveHTML();
}

Merging two DOMDocument nodes

<table>
<tr>
<th>Year</th>
<th>Score</th>
</tr>
<tr>
<td>2014</td>
<td>3078</td>
</tr>
</table>
If I have the above table being successfully stored as a variable, how could I append it to a div with an overflow-x style attribute?
I've tried the following snippet but no cigar:
$div = str_get_html('<div style="overflow-x:auto;"></div>');
$div = $div->find('div');
$div = $div->appendChild($table);
return $div;
so expected output should be:
<div style="overflow-x:auto;">
<table>
<tr>
<th>Year</th>
<th>Score</th>
</tr>
<tr>
<td>2014</td>
<td>3078</td>
</tr>
</table>
</div>

Hope this one will give you a basic idea of implementation. Here we are using DOMDocument.
Try this code snippet here
<?php
ini_set('display_errors', 1);
//creating table node
$tableNode='<table><tr><th>Year</th><th>Score</th></tr><tr><td>2014</td><td>3078</td></tr></table>';
$domDocument = new DOMDocument();
$domDocument->encoding="UTF-8";
$domDocument->loadHTML($tableNode);
$domXPath = new DOMXPath($domDocument);
$table = $domXPath->query("//table")->item(0);
//creating empty div node.
$domDocument = new DOMDocument();
$element=$domDocument->createElement("div");
$element->setAttribute("style", "overflow-x:auto;");
$result=$domDocument->importNode($table,true);//importing node from of other DOMDocument
$element->appendChild($result);
echo $domDocument->saveHTML($element);

How to select the Last elements attribute and change its value on html with php

HTML file (Demo)
<table>
<tr>
<td rowspan="1"> 1 </td>
<td rowspan="1"> 2 </td>
<td rowspan="1"> 3 </td>
</tr>
</table>
When I'll trigger the PHP file, it should get the last rowspan of the HTML file and change its value to 2.

$html = new DOMDocument();
$html->loadHTMLFile($file);
// find the last td by xpath and set value
$xpath = new DOMXpath($html);
$td = $xpath->query("(//td)[last()]")->item(0)->setAttribute('rowspan', 2);
echo $html->saveHTML();
UPDATE
$xpath = new DOMXpath($html);
$tds = $xpath->query("//td[position()=last() or (position()=last()-1)]");
foreach($tds as $td)
$td->setAttribute('rowspan', 5);

PHP parsing won't find "span" tags

I'm trying to find the span tags on a website similar to this: http://www.pointstreak.com/prostats/leagueschedule.html?leagueid=49&seasonid=14225. The tags I need are these:
However, when I use code such as the following:
$my_url = 'http://www.pointstreak.com/prostats/leagueschedule.html?leagueid=49&seasonid=14225';
$html = file_get_contents($my_url);
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
//Put your XPath Query here
$my_xpath_query = "//span";
$result_rows = $xpath->query($my_xpath_query);
// Create an array to hold the content of the nodes
$statsListings = array();
//here we loop through our results (a DOMDocument Object)
foreach ($result_rows as $result_object) {
$statsListings[] = $result_object->nodeValue;
}
echo json_encode($statsListings);
The only output I get is [].
If I replace $statsListings[] = $result_object->nodeValue; with $statsListings[] = $result_object->childNodes->item(0)->nodeValue;, I still get the same [] as output. When there are clearly span tags with values, why am I getting nothing?

XPath is not guilty at all.
Span tags are added dinamically. Just have a look at the source code of the page, not the DOM-Structure, which may be already modified by javascript, but use "view-source:" and you will see exactly the same html, as it is parsed by XPath.
It would be a good idea to have a look at the table with class tablelines? probably, you have there everything you may need.
You should skip "maincolor" and "tableheader", and start processing with "light" class.
<table width="98%" class="tablelines" cellpadding="2" border="0" cellspacing="1">
<tr class="maincolor">
<td colspan="8" align="right">All Times Local</td>
</tr>
<tr class="tableheader">
<td width="4%">
<b>GN</b>
</td>
<td nowrap width="21%">
<b>AWAY</b>
</td>
<td nowrap width="21%">
<b>HOME</b>
</td>
<td width="14%"><b>DATE</b></td>
<td width="11%"><b>TIME</b></td>
<td width="8%"><b>SCORE</b></td>
<td nowrap align="right" width="*"><b>BOXSCORE</b></td>
<td nowrap align="center" width="4%"><b>GS</b></td>
</tr>
<tr class="light">
<td></td>
<td>Sioux City
<b>1</b></td>
<td>Sioux Falls
<b>5</b></td>
<td>Tue, Apr 14</td>
<td> 7:05 PM</td>
<td> <b>1 - 5</b> </td>
<td align="right">
<img src="/images/gamelive_icon.gif" title="Click here for Game Live!" alt="Click here for Game Live" border="0">
Final</td>
<td align="center">
<img src="/images/playersection/prostats/gslink.gif" border="0">
</td>
</tr>
For example, try this:
$my_url = 'http://www.pointstreak.com/prostats/leagueschedule.html?leagueid=49&seasonid=14225';
$html = file_get_contents($my_url);
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
//Put your XPath Query here
$my_xpath_query = "//tr[#class='light']/td";
$result_rows = $xpath->query($my_xpath_query);
echo $result_rows->length;
// Create an array to hold the content of the nodes
$statsListings = array();
//here we loop through our results (a DOMDocument Object)
foreach ($result_rows as $result_object) {
$statsListings[] = $result_object->nodeValue;
}
echo json_encode($statsListings);
Probably I have found what you need, and even in nice JSON form:
