    <p>In my database I have values like this:</p> <pre><code>&lt;p class="description"&gt;Text here &lt;a href=#&gt;Text here&lt;/a&gt; &lt;/p&gt; </code></pre> <p>And I need that whole <code>&lt;p&gt;</code> object to replace the same <code>&lt;p class="description&gt;</code> in a template file.</p> <pre><code>import sys from HTMLParser import HTMLParser from xml.etree import cElementTree as etree import psycopg2 import psycopg2.extras class LinksParser(HTMLParser): def __init__(self): HTMLParser.__init__(self) self.tb = etree.TreeBuilder() def handle_starttag(self, tag, attributes): self.tb.start(tag, dict(attributes)) def handle_endtag(self, tag): self.tb.end(tag) def handle_data(self, data): self.tb.data(data) def close(self): HTMLParser.close(self) return self.tb.close() conn = psycopg2.connect(dbname="**", user="**", password="**", host="/tmp/", port="**") cur.execute("SELECT * FROM landingpagedata;") row = cur.fetchone() template = 'template.html' parser = LinksParser() parser.feed(open(template).read()) root = parser.close() #p_class_description p = root.find(".//p[@class='description']") p.text = str(row['p_class_description']) f = open(row['new_html_page'], 'w') root.write(f) parser = LinksParser() </code></pre> <p>What I end up with in the file is this:</p> <pre><code>&lt;p class="suggested_readings"&gt;&amp;lt;p class="suggested_readings"&amp;gt;Text here &amp;lt;a href=#;"&amp;gt;Text here &amp;lt;/a&amp;gt;.&amp;lt;/p&amp;gt; &lt;a href=#&gt;Text from template&lt;/a&gt; and more from template&lt;/p&gt; </code></pre> <p>I can't seem to replace the whole element with this element. Or, should I be trying to store an actual element in my database? So helpless here.</p> <p>Thanks!!!</p>

    1. COIn your database is there a `<p>` or `&lt;p&gt;` and the column name is `p_class_description`?

    3. COin `parser.feed()` you open the template but after that you look for a class named `description` that is in the `<p>` inside the database.

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.
