Are you actually getting results from "string(/\|$/,1)"? I get what I
would expect:
irb(main):001:0> st="joe|blogg|clothing|"
=> "joe|blogg|clothing|"
irb(main):004:0> st(/(.*)\|$/)
#<Class:0x3f99248>: undefined method `st' for main:Object

I think you mean [ ]

Try this:

string[/(.*)\|$/,1]

irb(main):010:0> st[/(.*)\|$/,1]
=> "joe|blogg|clothing"

By the way, if you're doing this to split up that string into joe,
blogg and clothing later, you can just skip the Regex and use split:

irb(main):011:0> st.split("|")
=> ["joe", "blogg", "clothing"]
