Question

I’m looking to capture just the number after vspace. How would you do that in regex? Here is a sample string.

<img align="left" alt="dude its me" border="10" height="168" hspace="30"  vspace="10" width="130" />

So the end result would be 10

Answer 1

>> s = '<img align="left" alt="dude its me" border="10" height="168" hspace="30"  vspace="10" width="130" />'
>> /vspace="(\d+)"/.match(s)[1]
=> "10"

or, if you’re not sure if it exists or not:

if /vspace="(\d+)"/ =~ s
  puts $1
else
  puts "no match"
end
