    <p>I am trying to scrape a pure static html page with tabular data in it using Nodejs &amp; Cheerio. But the problem is that, the page is am trying to scrape doesnt have proper HTML DOM. I mean, there are many opening tags which are not closed. There are other closing tags(<code>&lt;/table&gt;</code>) which has no openings.</p> <p>A sample Code (Alert: The Code is close to real sample &amp; html is broken)</p> <pre><code> &lt;body topmargin="0" leftmargin="0" marginheight="0" marginwidth="0" bgcolor="#FFFFFF" text="#000000" link="#003399" vlink="#003399" alink="#FF8000"&gt; &lt;table border="0" cellpadding="0" cellspacing="0" width="100%"&gt; &lt;tr&gt;&lt;td bgcolor="#445BC6"&gt;hii&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt; &lt;td align="right" bgcolor="#D9D9E8" width="100%"&gt; &lt;p class="menu"&gt;&lt;b&gt;&lt;font color="#000000"&gt;&lt;a href="details.php?type=contact&amp;npo_id=18430"&gt;Individuals&lt;/a&gt;&lt;/font&gt;&lt;/b&gt;&amp;nbsp;&amp;nbsp; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;P&gt; &lt;TABLE CELLPADDING=8&gt;&lt;TR&gt;&lt;TD&gt;&amp;nbsp;&lt;/TD&gt;&lt;TD&gt; &lt;TABLE CELLPADDING=8 STYLE="border-collapse: collapse" BORDER=1 WIDTH=80% ALIGN=cemter&gt; &lt;TR&gt;&lt;TD BGCOLOR="D8D8C4" VALIGN=top ALIGN=right&gt;&lt;P&gt;&lt;B&gt;Data 1&lt;/B&gt;&lt;/TD&gt; &lt;TD&gt;&lt;P&gt;&lt;B&gt;Data 2&lt;/B&gt;&lt;/TD&gt; &lt;/TR&gt; &lt;TR&gt;&lt;TD BGCOLOR="D8D8C4" VALIGN=top ALIGN=right&gt;&lt;P&gt;&lt;B&gt;Data 3&lt;/B&gt;&lt;/TD&gt; &lt;TD&gt;&lt;P&gt;Data 4&lt;/TD&gt; &lt;/TR&gt; &lt;/TABLE&gt; &lt;/TD&gt;&lt;/TR&gt;&lt;/TABLE&gt; &lt;tr&gt; &lt;td width="100%" valign="bottom" colspan="2" align="center"&gt; &lt;p&gt; &lt;a href="#top"&gt;another dirty content&lt;/a&gt;&lt;br&gt; &lt;a href="#top"&gt;&lt;font color="#000000"&gt;table is wrong&lt;/font&gt;&lt;/a&gt;&lt;/p&gt; &lt;/td&gt; &lt;/tr&gt;&lt;/table&gt;&lt;/div&gt; </code></pre> <p>&nbsp;</p> <p></p> <p>As one can see there are P tags which are not closing.. At the bottom there is <code>&lt;/table&gt;</code> &amp; <code>&lt;/div&gt;</code> tags which are not opening. So how do i fetch Data1, Data2, Data3, Data4 using cheerio &amp; nodejs ? Any other library will also do which is efficient in parsing such data</p> <p>EDIT(SOLUTION): The problem is solved. All I did was just converted the html tags to lower-case and it worked fine..Am not sure why lower-case is important but it just worked for cheerio</p>

    1. COScraping with regexes is not that difficult, especially if the pages all have similar formatting. Here: http://pastebin.com/SRDYBxpX is an example written in python that scrapes piratebay. Regexes have the definite advantage that they ignore any issues with closing and opening tags. and you can use the tags enclosing the data you require to safely delimit what the given regex will capture.

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.
