Removing Unwanted Scraped Text

Lucien Lachance · 08-25-2014, 06:38 PM

How can I match this string? I would like to remove the first three words with the pipe characters next to each other i.e., "Cookbook | Ingredients | Recipes".

"Cookbook | Ingredients | Recipes Ingredients"

So far I have:

Code:

line.text.gsub(/\t|\[edit\]/, '') # removes tabs and edit hyperlink tags

Hi,

grep can be used for string matching. If that answer is not what you are looking for, then perhaps you could provide a little more information about what you are trying to do.

OP had a detailed example. I was prepared to respond with a grep -v one-liner but then he edited his post to something different.

I apologize, the tag should've been ruby. I can't use grep, I can only use a regex pattern in the gsub method. I just don't know how to begin targeting that text. I thought about targeting any word followed by a pipe symbol like so:

Code:

 line.text.gsub(/\t|\[edit\]|w+.\|/, '')

but there might be a better way of grabbing this.

Hi,

why do you need to use a regex? What is wrong with using standard string substitution? Eg

Code:

line.text.sub('Cookbook | Ingredients | Recipes Ingredients','')

Nothing, I guess I was hoping there was a way to keep it short because I may have to add in additional substitutions to making the patten quite long. I guess I overthought this...

Alone I am not sure I see the relevance of the question? Either evo2's suggestion or simply sub(/.*/,'') ... as you can see, without any context most solutions will work.
