Question

I am trying to get the text between two tag.

<b> foo</b>bar<br/> => bar

I tried using '<b>asdasd</b>qwe<br/>'.scan(/<b>[a-zA-Z0-9]*<\/b>(.*)<br\/>/) and it gives me proper result.

but when I try this :

'<b>exclude</b>op1<br/>exclude 2<b>exclude</b>op2<br/>exclude 2<b>exclude</b>op3<br/>exclude 2'.scan(/<b>[a-zA-Z0-9]*<\/b>(.*)<br\/>/) { |ele|
puts ele
}

It matches the first <b> tag and the last <br/> tag and returns the whole string I was expecting an array of matches

Answer 1

Change (.*) to (.*?) to make it ungreedy

/<b>[a-zA-Z0-9]*<\/b>(.*?)<br\/>/

Test

[2] pry(main)> '<b>exclude</b>op1<br/>exclude 2<b>exclude</b>op2<br/>exclude 2<b>exclude</b>op3<br/>exclude 2'.scan(/<b>[a-zA-Z0-9]*<\/b>(.*?)<br\/>/) { |ele|
[2] pry(main)*   puts ele
[2] pry(main)* }  
op1
op2
op3
