how can i grab my tables and display them on another page using reg-ex

[luke]

For some reason

page 1.html // get contents from page 2.html

 
function get_tag($htmlelement,$attr, $value, $html) 
{
    $attr = preg_quote($attr);
    $value = preg_quote($value);
 
    if($attr!='' && $value!='')
    {
 
        $tag_regex = '/<'.$htmlelement.'[^>]*'.$attr.'="'.$value.'" width="100%">(.*?)<\\/'.$htmlelement.'>/si';
 
        $matchCount = preg_match($tag_regex,$html,$matches);
 
            if ($matchCount > 0) 
            {
            echo("$matchCount matches found.\n");
            }
                else 
                {
                echo("no records");
                }
 
    }
}    
$htmlcontent = file_get_contents("http://page2.html/");
$extract = get_tag("table","class", "tablemenu", $htmlcontent);
 
    echo $extract;
 
 
 
 

page2.html

I would like to grab all of the tables from the page and display them on another one.

 
// more code
 
<table width="100%" class="tablemenu">
<tbody>
<tr>
<td> 
 
</td>
</tr>
</tbody>
</table>
 
<table width="100%" class="tablemenu">
<tbody>
<tr>
<td> 
   // some data
</td>
</tr>
</tbody>
</table>
 
<table width="100%" class="tablemenu">
<tbody>
<tr>
<td> 
   // some data
</td>
</tr>
</tbody>
</table>
 
<table width="100%" class="tablemenu">
<tbody>
<tr>
<td> 
   // some data
</td>
</tr>
</tbody>
</table>
 
// more code
 
 

I have kept trying but had no luck :(

Regular expressions are not a good way to find things in a HTML document. HTML syntax is to irregular for it to be reliable. You need an actual parser if you want this to work properly.

PHP has a built in libraries that can be used to parse HTML documents. Most of them are more focused on XML, but many can also be used to deal with HTML. - The DOM extension, for example, has a DOMDocument class with a loadHTMLFile method. With that, you can traverse the HTML structure in much the same way you would in JavaScript.

For example:

<?php
 
$filePath = "/path/to/HTML/file.html";
 
// Load the HTML file.
$dom = new DOMDocument();
$dom->loadHTMLFile($filePath);
 
// Find all the tables.
$tables = $dom->getElementsByTagName("table");
 
// Go through the table list and look for tables
// with the class: "tablemenu"
if ($tables && $tables->length > 0) {
    for ($i = 0; $i < $tables->length; ++$i) {
        $item = $tables->item($i);
        $class = $item->attributes->getNamedItem("class")->nodeValue;
        if ($class == "tablemenu") {
            // The $item here would be one of the
            // tables we are looking for!
        }
    }
}

Getting an error Trying to get property of non-object in C:\wamp\www

reffers to this line...

$class = $item->attributes->getNamedItem("class")->nodeValue;

but my table does print out.

$filePath = "http://msn.net/";
 
// Load the HTML file.
$dom = new DOMDocument();
@$dom->loadHTML(file_get_contents($filePath));
 
// Find all the tables.
$tables = $dom->getElementsByTagName("table");
 
if ($tables && $tables->length > 0) {
    for ($i = 0; $i < $tables->length; ++$i) {
        $item = $tables->item($i);
        $class = $item->attributes->getNamedItem("class")->nodeValue;
 
        if ($class == "tablemenu") {
 
           echo $item->nodeValue;
           echo "<br />";
        }
    }
}
