how to parse contents from a html file using CURL?

问题:

I want to parse an XHTML content using CURL. How to scrap transaction number, weight, height, Width between <table> tags. How to scrap only the contents from this HTML document and get it as array using CURL?

transactions.php

 <table border=0 cellspacing=0 width=100%>
       <tr> 
        <td colspan="2">&nbsp;</td>
      </tr>
      <tr> 
        <td width="30%" class="Mellemrubrikker">Transaction Number::</td>
        <td width="70%">24752734576547IN</td>
      </tr>
      <tr> 
        <td width="30%" class="Mellemrubrikker">Weight:</td>
        <td width="70%">0.85 kg</td>
      </tr>
      <tr> 
        <td width="30%" class="Mellemrubrikker">Length:</td>
        <td width="70%">543 mm.</td>
      </tr>
      <tr> 
        <td width="30%" class="Mellemrubrikker">Height:</td>
        <td width="70%">156 mm.</td>
      </tr>
      <tr> 
        <td width="30%" class="Mellemrubrikker">Width:</td>
        <td width="70%">61 mm.</td>
      </tr>
      <tr> 
         <td colspan="2">&nbsp;</td>
      </tr>    
    </table>

index.php

<?php
$url = "http://localhost/htmlparse/transactions.php";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
//print_r($output);
echo $output;
?>

This code gets whole html content from transactions.php . How to get data between <table> as an array value ?

回答1:

Try simple html dom from http://simplehtmldom.sourceforge.net/

If you don't mind to use python or perl you can use beautifulsoup or WWW-Mechanize

回答2:

I would use the Document Object Model rather than writing your own parsing code or (God forbid!) regular expressions.

Here's an example in PHP: PHP Parse HTML code
