Get data from table using regex php - php

I want to extract some data from a table using php preg_match_all(). I have the html as under,
I want to get the values in td,
say Product code: RC063154016.
How can I do that? I don'y have any experience with regex,
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td><span>Product code:</span> RC063154016</td>
<td><span>Gender:</span> Female</td>
</tr>
</tbody>
</table>


Use DomDocument
$str = <<<STR
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td><span>Product code:</span> RC063154016</td>
<td><span>Gender:</span> Female</td>
</tr>
</tbody>
</table>
STR;
$dom = new DOMDocument();
#$dom->loadHTML($str);
$tds = $dom->getElementsByTagName('td');
foreach($tds as $td){
echo $td->nodeValue . '<br>';
}
OUTPUT
Product code: RC063154016
Gender: Female


This should do for you:
preg_match_all('|<td><span>Product code:</span>([^<]*)</td>|', $html, $match);
But if you think there can be random white spaces around tags, then this one:
preg_match_all('|<td>\s*<span>\s*Product code:\s*</span>([^<]*)</td>|', $html, $match);


$data = <<<HTML
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td><span>Product code:</span> RC063154016</td>
<td><span>Gender:</span> Female</td>
</tr>
</tbody>
</table>
HTML;
if(preg_match_all('#<td>\s*<span>Product code:</span>\s*([^<]*)</td>#i', $data, $matches)) {
print_r($matches);
}


Use any one parser and parse the HTML and use it. Don't use preg* functions here. Please read this answer How do you parse and process HTML/XML in PHP?

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:

PHP Table Reader

How to read and get the ISP value from html table?
<table style="padding-top:10px;">
<tbody>
<tr>
<th>ISP:</th>
<td>My Provider</td>
</tr>
<tr><th>Organization:</th><td nowrap=""></td>
</tr>
<tr><th>Connection:</th>
</tbody></table>

Given you lack of information, a regular expression would be the easiest solution.
$matches = array();
preg_match("<th>ISP:</th>[\r\n\s\t]*<td>(.*)</td>", "<th>ISP:</th><td>My Provider</td>...", $matches);
var_dump($matches);

PHP Simple HTML DOM Parser how to get Third table using find method

I have HTML code like following structure.
How can I fetch the 3rd table's content from this HTML code using PHP Simple HTML DOM find method?
<table width="100%" cellspacing="0" cellpadding="0" border="0">
<tbody>
<tr>
<td>
<table width="100%" cellspacing="0" cellpadding="0" border="0">
<tbody>
<tr>
<td>
<table width="100%" cellspacing="0" cellpadding="0" border="0">
.......
</table>
</td>
<tr>
..........
<td>
<tr>
</tbody>
</table>

To get third table pass second argument(index start from 0) in find method.
$html = file_get_html(<your_file_url/html_code>);
$html->find("table", 2);

The tables are nested so:
$dom->find("table", 0); # first table
$dom->find("table table", 0); # second table
$dom->find("table table table", 0); # third table

just an idea, try this:
// Find first <table> in first <td>
$html = file_get_html('yours.htm');
$var = $html->find('td', 0)->find('table', 0);

I am not that sure but you can try something like below:
$dom = new DomDocument;
$dom->loadXML($YourHTML);
//I have written as item(1) to point at the second table
$params = $dom->getElementsByTagName('table')->item(1);

php regex or html dom parsing

I use regex for HTML parsing but I need your help to parse the following table:
<table class="resultstable" width="100%" align="center">
<tr>
<th width="10">#</th>
<th width="10"></th>
<th width="100">External Volume</th>
</tr>
<tr class='odd'>
<td align="center">1</td>
<td align="left">
http://xyz.com
</td>
<td align="right">210,779,783<br />(939,265 / 499,584)</td>
</tr>
<tr class='even'>
<td align="center">2</td>
<td align="left">
http://abc.com
</td>
<td align="right">57,450,834<br />(288,915 / 62,935)</td>
</tr>
</table>
I want to get all domains with their volume(in array or var) for example
http://xyz.com - 210,779,783
Should I use regex or HTML dom in this case. I don't know how to parse large table, can you please help, thanks.

here's an XPath example that happens to parse the HTML from the question.
<?php
$dom = new DOMDocument();
$dom->loadHTMLFile("./input.html");
$xpath = new DOMXPath($dom);
$trs = $xpath->query("//table[#class='resultstable'][1]/tr");
foreach ($trs as $tr) {
$tdList = $xpath->query("td[2]/a", $tr);
if ($tdList->length == 0) continue;
$name = $tdList->item(0)->nodeValue;
$tdList = $xpath->query("td[3]", $tr);
$vol = $tdList->item(0)->childNodes->item(0)->nodeValue;
echo "name: {$name}, vol: {$vol}\n";
}
?>

What's wrong with this preg_match_all

I'm using file_get_contents to read a .html file that has a table.
<table id="someTable" style="width:100%;margin-bottom:0;">
<tr style="display:none;">
<td style="padding-left:25px;">Some text</td>
</tr>
<tr style="display:none;">
<td style="padding-left:25px;">another text</td>
</tr>
</table>
When I use preg_match_all to read the table, I get nothing when I count $matches[1]
preg_match_all('/<table id="someTable" style="width:100%;margin-bottom:0;">(.*)<\/table>/', $html, $matches);
$co = count($matches[1]);

Add modifier s to your preg_match.
preg_match_all('/<table id="someTable" style="width:100%;margin-bottom:0;">(.*)<\/table>/s', $html, $matches);
