Ruby Regex not matching what it should be

Question

I've got the following regex:

regex = /\$([a-zA-Z.]+)/

and the following query

query = "Show me the PE Ratio for $AAPL, $TSLA"

Now regex.match(query) should capture AAPL and TSLA, but instead I get the following:

#<MatchData "$AAPL" 1:"AAPL">

which is completely wrong. Anyone know why?

Note that this regex works fine on Rubular: http://rubular.com/r/j0maQHnVFF

Why do you claim it wrong? It is not wrong. – sawa Jun 04 '14 at 03:01 — sawa, Jun 04 '14 at 03:01

In Ruby the .match method will only return the first capture. You need it to return all captured matches, like the /g flag in PCRE

You can use the scan method. The scan method will either give you an array of all the matches or, if you pass it a block, pass each match to the block.

Code

query.scan(/\$([a-zA-Z.]+)/)

Fixed it, needed to use .scan instead of .match

Doesn't it? It could be expanded upon and better phrased but it is an answer. – indivisible Jun 04 '14 at 03:42
