Challenge #13: HTML Table Parsing

[GeneR]

The link to the solution for last challenge #12 is HERE.

For this challenge let’s look at creating a multi-level hierarchy from employee-manager data. As always there are several ways to do this challenge, I have designated it as an advanced challenge because some of the more complex functions like RegEx can be used, but it is not absolutely necessary. 

The use case:

We have HTML data that is in a single field, the HTML contains an HTML Table.

The input contains a series of name/value pairs within the description field. The description field has a HTML table that contains 14 name/value contained within <td> tags. Each pairing can be found on a different row (designated by the <tr> tag).

The objective is to produce a table containing the 14 name/value pairs.

Good luck, I look forward to your feedback.

I'm not familiar with HTML so I'm not sure how well my solution would work on other HTML examples. My bonus was that I got to use one tools in the labratory menu!

I added the second record to make sure the make columns would work with more than 1 record.

I have never seen the 'Make Columns" tool in use before.   Nice Job!

Good work Alex!

Another proof that there are a lot of ways to accomplish a goal in Alteryx!

I'm enjoying these weekly challenges.  Applying quite a bit on my projects - one of which is parsing html tables.

First formula line does large part of the work then two more formula to identify rows/columns

REGEX_Replace(Description,'<[t][^>]*>\W{0,1}|<\/[^t][^>]*>\W{0,1}|Null>','') will remove all but /td and /tr

REGEX_Replace(Description,'</tr>','~')

REGEX_Replace(Description,'</td>','|')

I made this alternative solution. Largely driven by trying to use the xml parse. This was quite a challenge as I'm new to Alteryx and don't know much about HTML so it took me a while to figure out. I explain each step in more detail in this blog post.

I'm not overly proud of this one @JoeM 😞

Kinda half-way between the provided solution from @GeneR, and the solution from @MarqueeCrew

My solution. I might bookmark this one to practice again down the line when I feel a bit more comfortable with my XML Parsing & RegEx skills... 

PS. @alex, the "Make Columns" tool has made my day. This will be SO useful for some of my work applications!! I went back & tested it out with my workflow on this challenge after I'd solved it with my original method, and it's so much cleaner, allows for fewer tools... Very cool tool!
