    <p>Let me start off by showing the 3 different type of strings I will be dealing with:</p> <pre><code>"&lt;h1&gt;Money Shake&lt;/h1&gt;&lt;p&gt;Money&lt;br&gt;Money&lt;br&gt;MORE MONEY&lt;/p&gt;&lt;p&gt;Take money and stuff in blender.&lt;/p&gt;&lt;p&gt;Blend.&lt;/p&gt;" "&lt;h1&gt;Money Shake&lt;/h1&gt;&lt;p&gt;Posted by Gordon Gekko&lt;/p&gt;&lt;p&gt;Money&lt;br&gt;Money&lt;br&gt;MORE MONEY&lt;/p&gt;&lt;p&gt;Take money and stuff in blender.&lt;/p&gt;&lt;p&gt;Blend.&lt;/p&gt;" "&lt;h1&gt;Money Shake&lt;/h1&gt;&lt;p&gt;Posted by Gordon Gekko&lt;/p&gt;&lt;p&gt;They're great&lt;/p&gt;&lt;p&gt;Yield: KA-CHING&lt;/p&gt;&lt;p&gt;Money&lt;br&gt;Money&lt;br&gt;MORE MONEY&lt;/p&gt;&lt;p&gt;Take money and stuff in blender.&lt;/p&gt;&lt;p&gt;Blend.&lt;/p&gt;" </code></pre> <p>Essentially, what I wish to do is to rip out the chunk that has the ingredients:</p> <pre><code>"&lt;p&gt;Money&lt;br&gt;Money&lt;br&gt;MORE MONEY&lt;/p&gt;" </code></pre> <p>This is the regex that I am using:</p> <pre><code>re.search(r'&lt;p&gt;[^&lt;/p&gt;](.*)&lt;br&gt;(.*?)&lt;/p&gt;', string, re.I) </code></pre> <p>When I use this on the first and second string, it does exactly what I want and returns me this match object:</p> <pre><code>"&lt;p&gt;Money&lt;br&gt;Money&lt;br&gt;MORE MONEY&lt;/p&gt;" </code></pre> <p>But when I use this on the third string, it returns me this match object:</p> <pre><code>"&lt;p&gt;They're great&lt;/p&gt;&lt;p&gt;Yield: KA-CHING&lt;/p&gt;&lt;p&gt;Money&lt;br&gt;Money&lt;br&gt;MORE MONEY&lt;/p&gt;" </code></pre> <p>What am I screwing up?</p> <hr> <p>@Blender</p> <p>Hi Blender, this is what I came up with in grabbing the chunks I want. I'm sure there is a better way, but consider that I'm 2 weeks into Python / programming:</p> <pre><code>def get_ingredients(soup): for p in soup.find_all('p'): if p.find('br'): return p ingredients = get_ingredients(soup) p_list = soup.find_all('p') ingredient_index = p_list.index(ingredients) junk = [] junk += p_list[:ingredient_index] instructions = [] instructions += p_list[ingredient_index+1:] </code></pre>

    1. CO"What am I screwing up?" I don't want to be judgmental, but the consensus here is that HTML and regular expressions don't mix. Even in the blender.

    3. CO`[^</p>]` is not really what you think it is. It is "not any of `<>/p` symbols". I think you need `(?!</p>)`

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.
