从String中提取Hashtags

Question

Let's say I have a paragraph with some hashtags and I want to copy those out and display them separately. Here's some dummy Text:

Visualize how you can e-enable #vertical #architectures? Whenever you can, disintermediate vertical #convergence? #Visualize how you can e-enable #vertical architectures? Whenever you can, disintermediate vertical #convergence?

I'd like to present the hashtags: #convergence, #Visualize, #vertical on my template.

Answer 1

str = "Visualize how you can e-enable #vertical #architectures?..."
str.scan(/#\w+/).flatten #=> ["#vertical", "#architectures", "#convergence",...]

Answer 2

Using regex,

input = 'Visualize how you can e-enable #vertical #architectures? Whenever you can, disintermediate vertical #convergence? #Visualize how you can e-enable #vertical architectures? Whenever you can, disintermediate vertical #convergence?'
input.scan(/#(\w+)/)

will get you

[["vertical"], ["architectures"], ["convergence"], ["Visualize"], ["vertical"], ["convergence"]]
