    <p>I am trying to parse a webpage and print out a table which is on the webpage. I am using php_simple_html dom parser. However, when I try to parse the table off the webpage, all the javascript commands to output the table get turned into comments within the php:</p> <pre><code>&lt;html&gt; &lt;script type="text/javascript" src="jquery.js"&gt;&lt;/script&gt; &lt;?php include 'crawling/simple_html_dom.php'; $html = file_get_html('http://uiucfreefood.com/'); $ret = $html-&gt;find('body', 0)-&gt;find('div', 10)-&gt;find('table',0); //gets to the table tag echo $ret; // nothing is echoed out because the original webpage uses jscript commands to write the table to the page but these commands get turned to comments for some reason. ?&gt; &lt;/html&gt; </code></pre> <p>When I inspect the element of the page where I am echoing the parsed information I am able to see that the table tag with all the info is in there but the jscript commands have been turned into comments. Is there a way for me to just grab the info and echo it out myself? I tried adding another ->find('tbody'); at the end of the parse command but it doesn't do anything. Any advice is appreciated. Thanks.</p> <p>EDIT: You can try this code out yourself if you download the simple_html_dom.php and include it in your php file.

The javascript commands are commented out in the original webpage also. Instead, the original webpage is using a javascript function to print out the table which I do not have defined. Writing that function myself should fix the issue. </p> <p>EDIT: yup, that worked. </p>

    2. COto be honest, I don't if there is a way for me to grab the info. I thought just keeping the jscript commands in there would be an easy way to just output the table as is. For example, I would just like every row of the table, such as: "lunch 11/12 12:00 428 Armory Building Integrating Undergrad Research in Large Introductory Classes"

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
