    <p>Im trying to extract some fields from the output at the end of this question with the following code:</p> <pre><code>doc = LH.fromstring(html2) tds = (td.text_content() for td in doc.xpath("//td[not(*)]")) for a,b,c in zip(*[tds]*3): print (a,b,c) </code></pre> <p>What i expect is to extract only the fields notificationNodeName,notificationNodeName,packageName,notificationEnabled </p> <p>The main problem with that is because i want to put the result into a database. and i need to, instead receiveing:</p> <p>Actual code returns:</p> <pre><code>('JDBCAdapter', 'JDBCAdapter', 'Package:Notif') ('Package', 'yes', 'Package_2:Notif') ('Package_2', 'yes') </code></pre> <p>What i need:</p> <pre><code>('Package:Notif','Package', 'yes') ('Package_2:Notif','Package_2', 'yes') </code></pre> <p>An unly solution that i found was:</p> <pre><code>doc = LH.fromstring(html2) tds = (td.text_content() for td in doc.xpath("//td")) for td, val in zip(*[tds]*2): if td == 'notificationNodeName': notificationNodeName = val elif td == 'packageName': packageName = val elif td == 'notificationEnabled': notificationEnabled = val print (notificationNodeName,packageName,notificationEnabled) </code></pre> <p>It works but doenst seen right for me, im sure it can be a better way to do it.</p> <p>Original HTML Output:</p> <pre><code>&lt;tbody&gt;&lt;tr&gt; &lt;td valign="top"&gt;&lt;b&gt;adapterTypeName&lt;/b&gt;&lt;/td&gt; &lt;td&gt;JDBCAdapter&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td valign="top"&gt;&lt;b&gt;adapterTypeNameList&lt;/b&gt;&lt;/td&gt; &lt;td&gt; &lt;table&gt; &lt;tbody&gt;&lt;tr&gt; &lt;td&gt;JDBCAdapter&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt;&lt;/table&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td valign="top"&gt;&lt;b&gt;notificationDataList&lt;/b&gt;&lt;/td&gt; &lt;td&gt; &lt;table&gt; &lt;tbody&gt;&lt;tr&gt; &lt;td&gt;&lt;table bgcolor="#dddddd" border="1"&gt; &lt;tbody&gt;&lt;tr&gt; &lt;td valign="top"&gt;&lt;b&gt;notificationNodeName&lt;/b&gt;&lt;/td&gt; &lt;td&gt;package:Notif&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td valign="top"&gt;&lt;b&gt;packageName&lt;/b&gt;&lt;/td&gt; &lt;td&gt;Package&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td valign="top"&gt;&lt;b&gt;notificationEnabled&lt;/b&gt;&lt;/td&gt; &lt;td&gt;unsched&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt;&lt;/table&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;table bgcolor="#dddddd" border="1"&gt; &lt;tbody&gt;&lt;tr&gt; &lt;td valign="top"&gt;&lt;b&gt;notificationNodeName&lt;/b&gt;&lt;/td&gt; &lt;td&gt;Package_2:notif&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td valign="top"&gt;&lt;b&gt;packageName&lt;/b&gt;&lt;/td&gt; &lt;td&gt;package_2&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td valign="top"&gt;&lt;b&gt;notificationEnabled&lt;/b&gt;&lt;/td&gt; &lt;td&gt;yes&lt;/td&gt; &lt;/tr&gt; and continues to more ... non relevant repetitive data. </code></pre>

    1. COI've rarely seen a problem that is more easily solved with xpath than with BeautifulSoup. (Actually, I've never been able to figure what class of problems xpath was supposed to be good for).

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).
