    <p>I have just started reading documentation and examples about DOM, in order to crawl and parse the document.</p> <p>For example I have part of document shown below:</p> <pre><code> &lt;div id="showContent"&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt; Crap &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td width="172" valign="top"&gt;&lt;a href="link"&gt;&lt;img height="91" border="0" width="172" class="" src="img"&gt;&lt;/a&gt;&lt;/td&gt; &lt;td width="10"&gt;&amp;nbsp;&lt;/td&gt; &lt;td valign="top"&gt;&lt;table cellspacing="0" cellpadding="0" border="0"&gt; &lt;tbody&gt;&lt;tr&gt; &lt;td height="30"&gt;&lt;a class="px11" href="link"&gt;title&lt;/a&gt;&lt;a&gt;&lt;br&gt; &lt;span class="px10"&gt;&lt;/span&gt; &lt;/a&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;img height="1" width="580" src="crap"&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td align="right"&gt; &lt;a href="link"&gt;&lt;img height="16" border="0" width="65" src="/buy"&gt;&lt;/a&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td valign="top" class="px10"&gt; &lt;p style="width: 500px;"&gt;description.&lt;/p&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt;&lt;/table&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; Crap &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; Crap &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/div&gt; </code></pre> <p>I'm trying to use the following code to get all the <code>tr</code> tags and analyze whether there is crap or information inside them:</p> <pre><code>$dom = new DOMDocument(); @$dom-&gt;loadHTML($html); $xpath = new DOMXPath($dom); $tags = $xpath-&gt;query('.//div[@id="showContent"]'); foreach ($tags as $tag) { $string=""; $string=trim($tag-&gt;nodeValue); if(strlen($string)&gt;3) { echo $string; echo '&lt;br&gt;'; } } </code></pre> <p>However I'm getting just stripped string without the tags, for example:</p> <pre><code>Crap Crap Title Description </code></pre> <p>But I would like to get:</p> <pre><code>&lt;tr&gt; &lt;td&gt;Crap&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;a href="link"&gt;title&lt;/a&gt; &lt;/tr&gt; </code></pre> <p>How to keep html nodes (tags)?</p>

    2. COYour XPath matches the div. To get the HTML you show, you'd have to use different XPath Query/Queries and then pass the results to `echo $dom->save($node)`. Please clarify what you are trying to get.

Guidance
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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
